How many 13-passenger vans will it take to drive all 52 members of the football team to an away game?
| 4 vans | |
| 8 vans | |
| 9 vans | |
| 5 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{52}{13} \) = 4
What is \( \frac{1}{5} \) x \( \frac{2}{7} \)?
| \(\frac{2}{5}\) | |
| \(\frac{1}{9}\) | |
| \(\frac{2}{35}\) | |
| \(\frac{1}{36}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{5} \) x \( \frac{2}{7} \) = \( \frac{1 x 2}{5 x 7} \) = \( \frac{2}{35} \) = \(\frac{2}{35}\)
If there were a total of 250 raffle tickets sold and you bought 15 tickets, what's the probability that you'll win the raffle?
| 2% | |
| 7% | |
| 6% | |
| 13% |
You have 15 out of the total of 250 raffle tickets sold so you have a (\( \frac{15}{250} \)) x 100 = \( \frac{15 \times 100}{250} \) = \( \frac{1500}{250} \) = 6% chance to win the raffle.
What is 9y3 + 9y3?
| 3 | |
| 18y9 | |
| 18y3 | |
| 18y-6 |
To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so add the coefficients and retain the base and exponent:
9y3 + 9y3
(9 + 9)y3
18y3
