How many 12-passenger vans will it take to drive all 31 members of the football team to an away game?
| 3 vans | |
| 9 vans | |
| 4 vans | |
| 16 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{31}{12} \) = 2\(\frac{7}{12}\)
So, it will take 2 full vans and one partially full van to transport the entire team making a total of 3 vans.
What is -3b5 x 9b4?
| -27b | |
| -27b9 | |
| 6b9 | |
| 6b20 |
To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:
-3b5 x 9b4
(-3 x 9)b(5 + 4)
-27b9
A bread recipe calls for 3\(\frac{1}{2}\) cups of flour. If you only have 1 cup, how much more flour is needed?
| 1\(\frac{1}{2}\) cups | |
| 1\(\frac{1}{4}\) cups | |
| 1\(\frac{7}{8}\) cups | |
| 2\(\frac{1}{2}\) cups |
The amount of flour you need is (3\(\frac{1}{2}\) - 1) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{28}{8} \) - \( \frac{8}{8} \)) cups
\( \frac{20}{8} \) cups
2\(\frac{1}{2}\) cups
Which of these numbers is a factor of 32?
| 3 | |
| 32 | |

12 members of a bridal party need transported to a wedding reception but there are only 2 5-passenger taxis available to take them. How many will need to find other transportation?
| 48 | |
| 9 | |
| 5 | |
| 2 |
There are 2 5-passenger taxis available so that's 2 x 5 = 10 total seats. There are 12 people needing transportation leaving 12 - 10 = 2 who will have to find other transportation.
