How many 11-passenger vans will it take to drive all 87 members of the football team to an away game?
| 4 vans | |
| 8 vans | |
| 10 vans | |
| 3 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{87}{11} \) = 7\(\frac{10}{11}\)
So, it will take 7 full vans and one partially full van to transport the entire team making a total of 8 vans.

A tiger in a zoo has consumed 84 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 154 pounds?
| 7 | |
| 4 | |
| 5 | |
| 10 |
If the tiger has consumed 84 pounds of food in 6 days that's \( \frac{84}{6} \) = 14 pounds of food per day. The tiger needs to consume 154 - 84 = 70 more pounds of food to reach 154 pounds total. At 14 pounds of food per day that's \( \frac{70}{14} \) = 5 more days.
What is 6x2 x 2x4?
| 12x-2 | |
| 12x4 | |
| 8x6 | |
| 12x6 |
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:
6x2 x 2x4
(6 x 2)x(2 + 4)
12x6
If the ratio of home fans to visiting fans in a crowd is 4:1 and all 45,000 seats in a stadium are filled, how many home fans are in attendance?
| 40,000 | |
| 32,667 | |
| 31,200 | |
| 36,000 |
A ratio of 4:1 means that there are 4 home fans for every one visiting fan. So, of every 5 fans, 4 are home fans and \( \frac{4}{5} \) of every fan in the stadium is a home fan:
45,000 fans x \( \frac{4}{5} \) = \( \frac{180000}{5} \) = 36,000 fans.
