How many 8-passenger vans will it take to drive all 93 members of the football team to an away game?
| 5 vans | |
| 3 vans | |
| 6 vans | |
| 12 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{93}{8} \) = 11\(\frac{5}{8}\)
So, it will take 11 full vans and one partially full van to transport the entire team making a total of 12 vans.
If all of a roofing company's 6 workers are required to staff 3 roofing crews, how many workers need to be added during the busy season in order to send 6 complete crews out on jobs?
| 2 | |
| 6 | |
| 12 | |
| 1 |
In order to find how many additional workers are needed to staff the extra crews you first need to calculate how many workers are on a crew. There are 6 workers at the company now and that's enough to staff 3 crews so there are \( \frac{6}{3} \) = 2 workers on a crew. 6 crews are needed for the busy season which, at 2 workers per crew, means that the roofing company will need 6 x 2 = 12 total workers to staff the crews during the busy season. The company already employs 6 workers so they need to add 12 - 6 = 6 new staff for the busy season.
Solve 4 + (3 + 2) ÷ 5 x 4 - 42
| 2 | |
| 1\(\frac{1}{2}\) | |
| 3 | |
| -8 |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
4 + (3 + 2) ÷ 5 x 4 - 42
P: 4 + (5) ÷ 5 x 4 - 42
E: 4 + 5 ÷ 5 x 4 - 16
MD: 4 + \( \frac{5}{5} \) x 4 - 16
MD: 4 + \( \frac{20}{5} \) - 16
AS: \( \frac{20}{5} \) + \( \frac{20}{5} \) - 16
AS: \( \frac{40}{5} \) - 16
AS: \( \frac{40 - 80}{5} \)
\( \frac{-40}{5} \)
-8
If there were a total of 450 raffle tickets sold and you bought 18 tickets, what's the probability that you'll win the raffle?
| 18% | |
| 8% | |
| 4% | |
| 10% |
You have 18 out of the total of 450 raffle tickets sold so you have a (\( \frac{18}{450} \)) x 100 = \( \frac{18 \times 100}{450} \) = \( \frac{1800}{450} \) = 4% chance to win the raffle.
A bread recipe calls for 2\(\frac{3}{8}\) cups of flour. If you only have 1\(\frac{1}{2}\) cups, how much more flour is needed?
| \(\frac{7}{8}\) cups | |
| 1\(\frac{1}{4}\) cups | |
| 2 cups | |
| 2\(\frac{1}{8}\) cups |
The amount of flour you need is (2\(\frac{3}{8}\) - 1\(\frac{1}{2}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{19}{8} \) - \( \frac{12}{8} \)) cups
\( \frac{7}{8} \) cups
\(\frac{7}{8}\) cups
