Jennifer scored 77% on her final exam. If each question was worth 2 points and there were 180 possible points on the exam, how many questions did Jennifer answer correctly?
| 64 | |
| 60 | |
| 69 | |
| 83 |
Jennifer scored 77% on the test meaning she earned 77% of the possible points on the test. There were 180 possible points on the test so she earned 180 x 0.77 = 138 points. Each question is worth 2 points so she got \( \frac{138}{2} \) = 69 questions right.
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 33 | |
| 31 | |
| 30 | |
| 28 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
If a car travels 325 miles in 5 hours, what is the average speed?
| 35 mph | |
| 20 mph | |
| 65 mph | |
| 30 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.
A tiger in a zoo has consumed 64 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 104 pounds?
| 10 | |
| 3 | |
| 1 | |
| 5 |
If the tiger has consumed 64 pounds of food in 8 days that's \( \frac{64}{8} \) = 8 pounds of food per day. The tiger needs to consume 104 - 64 = 40 more pounds of food to reach 104 pounds total. At 8 pounds of food per day that's \( \frac{40}{8} \) = 5 more days.
