A tiger in a zoo has consumed 80 pounds of food in 10 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 120 pounds?
| 15 | |
| 5 | |
| 14 | |
| 12 |
If the tiger has consumed 80 pounds of food in 10 days that's \( \frac{80}{10} \) = 8 pounds of food per day. The tiger needs to consume 120 - 80 = 40 more pounds of food to reach 120 pounds total. At 8 pounds of food per day that's \( \frac{40}{8} \) = 5 more days.
If a mayor is elected with 58% of the votes cast and 33% of a town's 21,000 voters cast a vote, how many votes did the mayor receive?
| 4,851 | |
| 5,128 | |
| 4,019 | |
| 4,227 |
If 33% of the town's 21,000 voters cast ballots the number of votes cast is:
(\( \frac{33}{100} \)) x 21,000 = \( \frac{693,000}{100} \) = 6,930
The mayor got 58% of the votes cast which is:
(\( \frac{58}{100} \)) x 6,930 = \( \frac{401,940}{100} \) = 4,019 votes.
Which of the following statements about exponents is false?
b1 = b |
|
all of these are false |
|
b1 = 1 |
|
b0 = 1 |
A number with an exponent (be) consists of a base (b) raised to a power (e). The exponent indicates the number of times that the base is multiplied by itself. A base with an exponent of 1 equals the base (b1 = b) and a base with an exponent of 0 equals 1 ( (b0 = 1).
The __________ is the smallest positive integer that is a multiple of two or more integers.

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.
If a car travels 45 miles in 3 hours, what is the average speed?
| 65 mph | |
| 20 mph | |
| 55 mph | |
| 15 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)
