Solve for X, log10X + log√10 X + log3√100 X = 27.
[ "1", "106", "104", "15" ]
B
Changing the base to 10, we get log√10 X = log10X / log10√10 = 2log10X log3√X = log10X / log103√100 = 3log10X / 2. Thus, log10X + 2log10X + 3/2 log10X = 27 => 9/2 log10X = 27 => log10X = 6 ANSWER:B

There are some new drivers going back to school. Teens who have recently gotten their driver's licenses may be taking the wheel to school this fall. However, parents fear when their teen starts driving. And it turns out that such parental fears are justified, so it's worth reviewing how to keep your teen safe while he or she is behind the wheel. Motor vehicle crashes are the leading cause of death among US teens. Drivers 16 to 19 years old are at the greatest risk of crashes. In fact, their risk is 4 times greater than that of older drivers. The teens at the greatest risk are those who are male, those carrying other teenage passengers in the car, and those still in their first year of driving. Nearly 50 percent of teen deaths related to automobile crashes happen on Fridays, Saturdays, or Sundays between the hours of 3 pm and midnight. Why are teens at higher risk of motor vehicle crashes? Development. Teens haven't completely matured mentally and have greater risktaking behaviors, possibly because they tend to underestimate the risk associated with a particular behavior. Teens also have a greater tendency to speed and to drive too close to the cars in front of them. No seatbelts. Teens have the lowest rate of seatbelt use among all driving groups. Alcohol. A least 25 percent of motor vehicle deaths in teens are related to drinking alcohol. Technological distractions .Cellphones,texting,MP3 players,and the like can all distract drivers greatly--and who more than teenagers? Be aware of your teen's driving practices and discuss safe driving habits when opportunities present themselves. Check out the applications and devices now available for restricting your teen's use of technology while driving. Some applications alert you to the danger when your teen is texting while the vehicle is moving. Another device blocks incoming and outgoing texts when the car is running--incoming messages get an automatic reply (eg. "I'm driving right now"), and phone calls go directly to voicemail. You can also get notifications if your teen tries to shut off the program. There are also GPS programs that let you know your new driver's whereabouts at all times. All in all, you can't be too cautious when teaching your teen how to be safe on the road. Teens probably turn away their attention from driving when they are _ .

A recent Living Social survey showed that Americans may live up to their poor reputation while travelling abroad. But what's more surprising is that many of those surveyed self-identified themselves as 'ugly' Americans and the world's worst travelers. Those in the U.S. ranked themselves as the worst travellers by a shocking 20 per cent, followed by 15 per cent saying the Chinese were the most substandard tourists. Americans topped the list as being the worst-behaved travelers in a survey of 5,600 respondents, 4,000 of whom were Americans. Other respondents were in Australia, Canada, Ireland and the United Kingdom. But even American respondents considered their compatriots as the worst travelers from a list of 16 nationalities. Canadians and Australians also put Americans in the No. 1 spot. Irish respondents pointed to U.K. residents and U.K. respondents gave Germans the nod. On the other hand, 37% of Americans opted for "none of the above" in answer to the worst-tourists question, displaying more tolerance and open-mindedness than the other nationalities. Other survey questions had respondents admitting _ from hotels. Four in ten U.S. survey-takers said they'd stolen something - mostly towels (28%) and bathrobes (8%). Other popular pinched items included pillows, remote controls, Bibles and sheets. Not surprising is that Americans have less time off from work than other nationalities. Americans reported getting 16 days off, compared with 28 days for the Irish, 27 days for Australians, 23 days for U.K. workers; and 21 days for Canadians. In the travel mishaps department, the most common travel disaster reported by Americans was lost luggage on an airline (21%); bad weather (21%); and getting very lost (16%). As for places Americans most want to see, Disney World and Las Vegas made the top 10, but they weren't at the top of the heap. And New York didn't make the cut. What's the best title of this passage?

Two friends have an argument that bleaks up their friendship forever, even though neither one can remember how the whole thing got started. Such sad events happen over and over in high schools across the country. In fact, according to an official report on youth violence, "In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence". Given that this is the case, why aren't students taught to manage conflict the way they are taught to solve math problems, drive cars, or stay physically fit? First of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult . For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn't in the sandwich, but in the way students deal with the conflict. Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words, name-calling, and accusation only add fuel to the emotional fir On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control. After both sides have calmed down, they can use another key strategy for conflict resolution; listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non-threatening questions to clarify the speaker's position. Then the two people should change roles. Finally, students need f. consider what they are hearing. This doesn't mean trying to figure out what's wrong with the other person. It means understanding what the real issue is and what both sides are trying to accomplish. For example, a shouting match over a peanut butter sandwich might happen because one person thinks the other person is unwilling to try new things. Students need to ask themselves questions such as these: How did this start? What do I really want? What am I afraid off As the issue becomes clearer, the conflict often simply becomes smaller. Even if it doesn't, careful thought helps both sides figure out a mutual solution. There will always be conflict in schools, but that doesn't mean there needs to be violence. After students in Atlanta started a conflict resolution program, according to Educators for Social Responsibility, "64 percent of the teachers reported less physical violence in the classroom; 75 percent of the teachers reported an increase in student cooperation; and 92 percent of the students felt better about themselves". Learning to resolve conflicts can help students deal with friends, teachers, parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country. After the conflict resolution program was started in Atlanta, it was found that _ .

A train overtakes two persons who are walking in the same direction in which the train is going, at the rate of 2 kmph and 4 kmph and passes them completely in 9 and 10 seconds respectively. The length of the train is:
[ "45m", "50m", "72m", "70m" ]
B
Explanation: 2 kmph = ( 2 x5/18)m/sec = 5/9m/sec. 4 kmph =(4x5/18)m/sec =10/9m/sec. Let the length of the train be x metres and its speed by y m/sec. Then, (x/y-5/9)=9and(x/y - 10/9)=10. 9y - 5 = x and 10(9y - 10) = 9x => 9y - x = 5 and 90y - 9x = 100. On solving, we get: x = 50. Therefore Length of the train is 50 m. ANSWER IS B

The number of ways to arrange 9 people in a row is 9! From this we want to subtract all the arrangements where the two friends are next to each other. If we consider them as one unit, then the number of arrangements of this 2-person unit and the 7 other friends is 8! And the number of arrangements of the two friends within this unit are 2 because the two friends can switch places. So the total number of arrangements of the 9 friends with the 2-person unit together is 8!*2 The total number of permutations where these two friends are not seated next to each other is 9! - 8!*2 = 7*8! = 282,240 The answer is E.

A hierarchical system has levels and each group at one of the levels includes groups at the next lowest level, so that at the lowest level each member belongs to a series of nested groups. An analogy is the nested series of directories on the main disk drive of a computer. For example, in the most inclusive grouping, scientists divide organisms into three domains: Bacteria, Archaea, and Eukarya. Within each domain is a second level called a kingdom. Each domain contains several kingdoms. Within kingdoms, the subsequent categories of increasing specificity are: phylum, class, order, family, genus, and species. As an example, the classification levels for the domestic dog are shown in Figure 12.3. The group at each level is called a taxon (plural: taxa). In other words, for the dog, Carnivora is the taxon at the order level, Canidae is the taxon at the family level, and so forth. Organisms also have a common name that people typically use, such as domestic dog, or wolf. Each taxon name is capitalized except for species, and the genus and species names are italicized. Scientists refer to an organism by its genus and species names together, commonly called a scientific name, or Latin name. This two-name system is called binomial nomenclature. The scientific name of the wolf is therefore Canis lupus. Recent study of the DNA of domestic.

What vessels supply blood to the myocardium and other components of the heart?
[ "rapid arteries", "specialized arteries", "surface arteries", "coronary arteries" ]
D
Coronary Arteries Coronary arteries supply blood to the myocardium and other components of the heart. The first portion of the aorta after it arises from the left ventricle gives rise to the coronary arteries. There are three dilations in the wall of the aorta just superior to the aortic semilunar valve. Two of these, the left posterior aortic sinus and anterior aortic sinus, give rise to the left and right coronary arteries, respectively. The third sinus, the right posterior aortic sinus, typically does not give rise to a vessel. Coronary vessel branches that remain on the surface of the artery and follow the sulci are called epicardial coronary arteries. The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery. The larger anterior interventricular artery, also known as the left anterior descending artery (LAD), is the second major branch arising from the left coronary artery. It follows the anterior interventricular sulcus around the pulmonary trunk. Along the way it gives rise to numerous smaller branches that interconnect with the branches of the posterior interventricular artery, forming anastomoses. An anastomosis is an area where vessels unite to form interconnections that normally allow blood to circulate to a region even if there may be partial.

"I can't concentrate." "My mind wanders when I try to study." Lack of concentration is one of the most common complaints heard at school. We all have the ability to concentrate. Think of the times when you were attracted to a super novel or the times when you were playing your guitar or piano. But at other times your mind races from one thing to another. Here are some tips. Rest from time to time. Remember to take short breaks. Lectures are usually 50 minutes long, and that's about the length of time most people can direct their attention to one task. But that's just an average. Your concentration time might be shorter (20-35 minutes) or longer (perhaps 90 minutes).When you take a break, you get more oxygen to your brain! When we sit for long periods, blood tends to be pooled in our lower body and legs. Get up and walk around the room for a couple of minutes. As a result, more oxygen is carried to the brain and you can concentrate better. _ If you study one subject for a long time, you may find it hard to concentrate. Many students improve their concentration by changing one subject to another every one to two hours. In this way you can pay more attention to something that's different. Reward yourself. Give yourself a reward when you've completed a task. The task might be small, such as staying with a difficult paper until you've finished. But giving yourself a reward can help you be more interested in doing other tasks. Increase your activity level. Your concentration wanders more easily if you just read an article straight through. Instead, take the heading for each part and turn it into a question. For this part, that would be, "How can I increase my activity level while studying?" Then study that part to answer that question. Do this routinely. The questions give us a focus for each part and increase our involvement . The writer wrote the passage to _ .

Not a metabolic product of urea cycle-
[ "Citrulline", "Ornithine", "Alanine", "Arginine" ]
C
Biosynthesis of urea occurs in five steps. 1) Carbamoyl phosphate synthase-I (CPS-I), a mitochondrial enzyme, catalyzes the formation of carbamoyl phosphate by condensation of CO2 and ammonia. Two molecules of ATP are required for the reaction. CPS-I is the rate-limiting enzyme of the urea cycle. It is an allosteric enzyme and allosterically activated by N-acetyl glutamate. 2) Ornithine transcarbamylase catalyzes the formation of citrulline from carbamoyl phosphate and ornithine. 3) Argininosuccinate synthase catalyzes the formation of argininosuccinate from citrulline and aspartate. This reaction requires 1ATP, but 2 high energy phosphate bonds are consumed as ATP is converted to AMP + PPi. The amino group of aspartate provides one of the two nitrogen atoms that appear in urea (The other one is provided by ammonia NH4). 4) Argininosuccinate lyase (argininosuccinase) catalyzes the cleavage of argininosuccinate into arginine and fumarate. Fumarate enters in TCA cycle. 5) Arginase catalyzes the formation of urea from arginine by hydrolytic cleavage of arginine to yield urea and ornithine. Ornithine is thus regenerated and can enter mitochondria to initiate another round of the urea cycle.

But, from 5 o'clock to 6 o'clock and from 6 o'clock to 7 o'clock (a span of hours), they would be exactly opposite only once (at exact 6 o'clock). Thus, during the span of 12 hours, the two hands would be exactly opposite 11 times. Hence, in the span of 24 hours they would be exactly opposite 22 times. ANSWER D

A couple of years ago, those who forecast that oil price would reach $ 100 a barrel were seen as doomsters. However, now some are predicting $ 200 a barrel. Had economists been told that oil price would barely pause at $ 100 before reaching the recent peak of nearly $ 127, they would no doubt have forecast terrible economic consequences. But the global economy, though interrupted by the high price of energy, is still chugging along. Meanwhile, inflation has picked up, but the headlinerates of inflation in most developed countries are nowhere near the levels seen in the 1970s and 1980s. There are three explanations for the oil price's unclear impact. The first is that nowadays developed economies are more efficient in their use of energy, thanks partly to the increased importance of service industries and the diminished role of manufacturing . According to the Energy Information Administration, the energy intensity of America's GDP fell by 42% between 1980 and 2007. A second theory is that the oil-price rise has been steady, not sudden, giving the economy time to adjust. Giovanni Serio of Goldman Sachs points out that in 1973 there was a severe supply shock because of the oil embargo , when the world had to cope with 10%-15% less crude almost overnight. Not this time. The third explanation turns the argument on its head; rather than oil harming the global economy, it is global expansion that is driving up the price of oil. The most important factor is the shift in favor of the developing economies. America has responded to high price in familiar fashion: UBS forecasts that demand will drop by 1.1% this year and will be no higher in 2010 than it was in 2004. But the demand from China and other emerging markets is more than offsetting this shortfall. What is the passage mainly talking about?

According to the octet rule, magnesium is unstable (reactive) because its valence shell has just two electrons. It is therefore likely to participate in chemical reactions in which it donates two electrons. 37 Water is a polar molecule. It has a region of weakly positive charge and a region of weakly negative charge. These regions are attracted to ions as well as to other polar molecules. Oils are nonpolar, and are repelled by water. 39 It is not. An exchange reaction might be AB + CD → AC + BD or AB + CD → AD + BC . In all chemical reactions, including exchange reactions, the components of the reactants are identical to the components of the products. A component present among the reactants cannot disappear, nor can a component not present in the reactants suddenly appear in the products. 41 Lemon juice is one hundred times more acidic than orange juice.

I'm going to have a great weekend. I'll go across Canada with my parents by car. We'll drive seven or eight hours a day. In Toronto, we'll stay in a big hotel. The food is very delicious. There's a big swimming pool and a lot of game rooms. I think I'll play there happily. But there'll be lots of people in the hotel, so I think we'll sleep in one room. And it's expensive. Then we are going to stay in a small cabin in the mountains. I really love it. The cabin is clean and quiet. We'll have two rooms, so I can get up late in the morning. But we have to get up early because we want to go swimming. There is a beautiful lake near the cabin. We also can go fishing and cook food outside. Where're they going to stay in Toronto?

B
Let the amount in Chris’s wallet be $x Donna has $7 more than Chrish's wallet = $(x + 7) Austin has 3 times than Donna's wallet = $3(x + 7) According to the problem, Donna, chris, and Austin have a total of $93 in their wallets. Therefore, x + (x + 7) + 3(x + 7) = 93 x + x + 7 + 3x + 21 = 93 5x + 28 = 93 - 28 -28 (subtract 28 from both sides) 5x = 65 or, 5x/5 = 65/5 (Divide both sides by 5) x = 13 Amount in Chris wallet = $x = $13 Amount in Donna's wallet = $(x + 7) = $(13 + 7) = $20 Amount in Austin 's wallet = $3(x + 7) = $3(13 + 7) = $3(20) = $ 60 Answer: Amount in Chris’s wallet: $13 Amount in Donna's wallet: $20 Amount in Austin's wallet: $60 correct answer B

Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren't doing any more physical activity than usual. Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men's blood pressure also dropped, which the researchers believed was due to weight lost. Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual--about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data. Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile. Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn't practical as a treatment. He says, half- jokingly, "If fat people plan their holidays, they might not go to the sea, but maybe to the mountain." In what manner does Lippl talk about the way of losing weight by spending holidays on mountains?

Many different sports were played, including boxing, running, throwing the discuss , though there were fewer sports involved than those in the modern Olympics. The Games were held every five years until they were forbidden by the Romans in AD 393. The first new Olympics were held in 1896 in Greece. From 1900, the Games were held every four years, only three Olympics were wiped out because of wars---1916, 1940 and 1944. Nowadays, different countries hold the Games in turns. The country which holds the Games provides vast facilities, including a stadium , swimming pools and accommodation , but competing countries pay their own players' expense. The Olympics start with the arrival in the stadium of a torch , lighted on Mount Olympus by the sun's rays. The well-known Olympic flag, however, is a modern conception : the five interlocking rings symbolize the uniting of all five continents that take part in the Games.

Tom Sawyer is known as one of the most beloved characters in American literature , but new research found that Mark Twain based this character on his friend named Tom Sawyer. He admired his firefighting friend so much that he gave the character his name. Mark Twain and Tom Sawyer had many adventures together, gambling in Nevada and drinking in pubs. Tom Sawyer once worked as a volunteer firefighter, policeman and customs officer. Before making his way out West, Tom Sawyer used his strength to save 90 people from a burning ship. Mark Twain was particularly moved by this story because his own brother died in a fire while working on a similar steamboat. The two men became friends immediately after meeting in 1863, with Tom Sawyer traveling to Virginia City, while Mark Twain was working as a reporter there. After one night they returned to San Francisco, Mark Twain told his friend that he would base a character in his yet-unwritten book on him. Tom Sawyer said, "One day he said to me, 'I'm going to put you between the covers of a book, Tom.' 'Go ahead, Sam,' I Said, 'but don't disgrace my name.'" Besides their fondness of drinking, the two men also shared a hobby for storytelling. Tom sawyer believed that it was his anecdotes about his own childhood that inspired Mark Twain to create a book on him. Finally Mark Twain said that the character of Tom sawyer was based on a mix of three real people---John B. Briggs, William Bowen and himself. In spite of this, the historical evidence shows that there might be a fourth, more prominent influencer. The text mainly tells us that _ .
