Latoya scored 88% on her final exam. If each question was worth 4 points and there were 200 possible points on the exam, how many questions did Latoya answer correctly?
| 44 | |
| 42 | |
| 50 | |
| 54 |
Latoya scored 88% on the test meaning she earned 88% of the possible points on the test. There were 200 possible points on the test so she earned 200 x 0.88 = 176 points. Each question is worth 4 points so she got \( \frac{176}{4} \) = 44 questions right.
What is \( \sqrt{\frac{4}{25}} \)?
| 3 | |
| \(\frac{2}{5}\) | |
| \(\frac{5}{7}\) | |
| 1 |
To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:
\( \sqrt{\frac{4}{25}} \)
\( \frac{\sqrt{4}}{\sqrt{25}} \)
\( \frac{\sqrt{2^2}}{\sqrt{5^2}} \)
\(\frac{2}{5}\)
What is \( \frac{3}{7} \) x \( \frac{3}{7} \)?
| \(\frac{2}{45}\) | |
| \(\frac{9}{49}\) | |
| \(\frac{4}{15}\) | |
| \(\frac{1}{10}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{7} \) x \( \frac{3}{7} \) = \( \frac{3 x 3}{7 x 7} \) = \( \frac{9}{49} \) = \(\frac{9}{49}\)
A tiger in a zoo has consumed 72 pounds of food in 8 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 126 pounds?
| 3 | |
| 7 | |
| 8 | |
| 6 |
If the tiger has consumed 72 pounds of food in 8 days that's \( \frac{72}{8} \) = 9 pounds of food per day. The tiger needs to consume 126 - 72 = 54 more pounds of food to reach 126 pounds total. At 9 pounds of food per day that's \( \frac{54}{9} \) = 6 more days.
