Monica scored 88% on her final exam. If each question was worth 4 points and there were 360 possible points on the exam, how many questions did Monica answer correctly?
| 85 | |
| 79 | |
| 71 | |
| 82 |
Monica scored 88% on the test meaning she earned 88% of the possible points on the test. There were 360 possible points on the test so she earned 360 x 0.88 = 316 points. Each question is worth 4 points so she got \( \frac{316}{4} \) = 79 questions right.
If there were a total of 250 raffle tickets sold and you bought 20 tickets, what's the probability that you'll win the raffle?
| 15% | |
| 17% | |
| 6% | |
| 8% |
You have 20 out of the total of 250 raffle tickets sold so you have a (\( \frac{20}{250} \)) x 100 = \( \frac{20 \times 100}{250} \) = \( \frac{2000}{250} \) = 8% chance to win the raffle.
What is the next number in this sequence: 1, 4, 10, 19, 31, __________ ?
| 38 | |
| 46 | |
| 52 | |
| 49 |
The equation for this sequence is:
an = an-1 + 3(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 + 3(6 - 1)
a6 = 31 + 3(5)
a6 = 46
If a car travels 585 miles in 9 hours, what is the average speed?
| 70 mph | |
| 75 mph | |
| 65 mph | |
| 60 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)What is \( \frac{1}{7} \) x \( \frac{3}{6} \)?
| \(\frac{1}{14}\) | |
| \(\frac{1}{28}\) | |
| \(\frac{1}{54}\) | |
| \(\frac{1}{2}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{7} \) x \( \frac{3}{6} \) = \( \frac{1 x 3}{7 x 6} \) = \( \frac{3}{42} \) = \(\frac{1}{14}\)
