D) 3/2
On a test with 42 questions, answering 37 correctly yields a score of approximately 88 percent. This result is obtained by dividing the number of correctly answered questions by the total number of questions, and then multiplying that result by 100 to find the percent.
The subject for this problem is percentages, a common topic in mathematics. To solve this, you need to relate the number of correct answers to the total number of questions. The formula for percent is (part / total) * 100, where the part is the number of problems you answered correctly (37), and total is the overall number of questions on the test (42).
In this case, you'd calculate (37 / 42) * 100, which equals approximately 88.09%. Therefore, if you answered correctly on 37 out of 42 questions, your score would be about 88 percent.

By using the principles of inverse variation, it is determined that it would take 20 workers 38 days to build a similar house.
The problem is an example of inverse variation, where the amount of time (days) to build a house decreases if the number of workers increases. In this specific scenario, one house was built in 76 days by 10 workers. We can represent the inverse variation relationship with the equation: days * workers = constant.
Using the given data, the constant can be calculated by multiplying the days by the number of workers, hence:
constant = 76 days * 10 workers = 760
To find the number of days it would take for 20 workers to build the house, we divide the constant by the number of workers:
days = constant / workers = 760 / 20 = 38 days
This means that it would take 20 workers 38 days to build a similar house.
