A tiger in a zoo has consumed 60 pounds of food in 5 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 132 pounds?
| 4 | |
| 5 | |
| 6 | |
| 7 |
If the tiger has consumed 60 pounds of food in 5 days that's \( \frac{60}{5} \) = 12 pounds of food per day. The tiger needs to consume 132 - 60 = 72 more pounds of food to reach 132 pounds total. At 12 pounds of food per day that's \( \frac{72}{12} \) = 6 more days.
Convert a-4 to remove the negative exponent.
| \( \frac{4}{a} \) | |
| \( \frac{1}{a^4} \) | |
| \( \frac{-4}{a} \) | |
| \( \frac{-1}{-4a} \) |
To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.
Latoya scored 78% on her final exam. If each question was worth 2 points and there were 80 possible points on the exam, how many questions did Latoya answer correctly?
| 31 | |
| 34 | |
| 35 | |
| 32 |
Latoya scored 78% on the test meaning she earned 78% of the possible points on the test. There were 80 possible points on the test so she earned 80 x 0.78 = 62 points. Each question is worth 2 points so she got \( \frac{62}{2} \) = 31 questions right.

Which of the following is an improper fraction?
\({a \over 5} \) |
|
\({2 \over 5} \) |
|
\(1 {2 \over 5} \) |
|
\({7 \over 5} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
