A bread recipe calls for 3\(\frac{3}{8}\) cups of flour. If you only have \(\frac{5}{8}\) cup, how much more flour is needed?
| 2\(\frac{3}{4}\) cups | |
| 1\(\frac{1}{4}\) cups | |
| 2\(\frac{5}{8}\) cups | |
| 2\(\frac{3}{8}\) cups |
The amount of flour you need is (3\(\frac{3}{8}\) - \(\frac{5}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{27}{8} \) - \( \frac{5}{8} \)) cups
\( \frac{22}{8} \) cups
2\(\frac{3}{4}\) cups
How many 6-passenger vans will it take to drive all 31 members of the football team to an away game?
| 6 vans | |
| 3 vans | |
| 11 vans | |
| 7 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{31}{6} \) = 5\(\frac{1}{6}\)
So, it will take 5 full vans and one partially full van to transport the entire team making a total of 6 vans.
Bob loaned Charlie $600 at an annual interest rate of 5%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $72 | |
| $20 | |
| $10 | |
| $30 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $600
i = 0.05 x $600
i = $30
4! = ?
4 x 3 |
|
4 x 3 x 2 x 1 |
|
3 x 2 x 1 |
|
5 x 4 x 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.
