How many 15-passenger vans will it take to drive all 32 members of the football team to an away game?
| 6 vans | |
| 3 vans | |
| 7 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 = \( \frac{32}{15} \) = 2\(\frac{2}{15}\)
So, it will take 2 full vans and one partially full van to transport the entire team making a total of 3 vans.

In a class of 36 students, 14 are taking German and 11 are taking Spanish. Of the students studying German or Spanish, 3 are taking both courses. How many students are not enrolled in either course?
| 27 | |
| 14 | |
| 12 | |
| 34 |
The number of students taking German or Spanish is 14 + 11 = 25. Of that group of 25, 3 are taking both languages so they've been counted twice (once in the German group and once in the Spanish group). Subtracting them out leaves 25 - 3 = 22 who are taking at least one language. 36 - 22 = 14 students who are not taking either language.
4! = ?
4 x 3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
|
4 x 3 |
|
3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
a(b + c) = ab + ac defines which of the following?
distributive property for division |
|
commutative property for division |
|
commutative property for multiplication |
|
distributive property for multiplication |
The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
