If there were a total of 150 raffle tickets sold and you bought 6 tickets, what's the probability that you'll win the raffle?
| 2% | |
| 13% | |
| 3% | |
| 4% |
You have 6 out of the total of 150 raffle tickets sold so you have a (\( \frac{6}{150} \)) x 100 = \( \frac{6 \times 100}{150} \) = \( \frac{600}{150} \) = 4% chance to win the raffle.
How many hours does it take a car to travel 385 miles at an average speed of 55 miles per hour?
| 1 hour | |
| 5 hours | |
| 7 hours | |
| 4 hours |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for time:
time = \( \frac{\text{distance}}{\text{speed}} \)
time = \( \frac{385mi}{55mph} \)
7 hours
Solve 3 + (2 + 5) ÷ 3 x 3 - 52
| 1\(\frac{1}{3}\) | |
| \(\frac{1}{4}\) | |
| -15 | |
| \(\frac{5}{8}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
3 + (2 + 5) ÷ 3 x 3 - 52
P: 3 + (7) ÷ 3 x 3 - 52
E: 3 + 7 ÷ 3 x 3 - 25
MD: 3 + \( \frac{7}{3} \) x 3 - 25
MD: 3 + \( \frac{21}{3} \) - 25
AS: \( \frac{9}{3} \) + \( \frac{21}{3} \) - 25
AS: \( \frac{30}{3} \) - 25
AS: \( \frac{30 - 75}{3} \)
\( \frac{-45}{3} \)
-15

April scored 88% on her final exam. If each question was worth 3 points and there were 240 possible points on the exam, how many questions did April answer correctly?
| 63 | |
| 67 | |
| 76 | |
| 70 |
April scored 88% on the test meaning she earned 88% of the possible points on the test. There were 240 possible points on the test so she earned 240 x 0.88 = 210 points. Each question is worth 3 points so she got \( \frac{210}{3} \) = 70 questions right.
