Solve 3 + (2 + 5) ÷ 3 x 2 - 52
| \(\frac{2}{9}\) | |
| -17\(\frac{1}{3}\) | |
| 2 | |
| 1\(\frac{1}{5}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
3 + (2 + 5) ÷ 3 x 2 - 52
P: 3 + (7) ÷ 3 x 2 - 52
E: 3 + 7 ÷ 3 x 2 - 25
MD: 3 + \( \frac{7}{3} \) x 2 - 25
MD: 3 + \( \frac{14}{3} \) - 25
AS: \( \frac{9}{3} \) + \( \frac{14}{3} \) - 25
AS: \( \frac{23}{3} \) - 25
AS: \( \frac{23 - 75}{3} \)
\( \frac{-52}{3} \)
-17\(\frac{1}{3}\)
Bob loaned Ezra $100 at an annual interest rate of 7%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $7 | |
| $28 | |
| $14 | |
| $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 $100
i = 0.07 x $100
i = $7
If there were a total of 300 raffle tickets sold and you bought 27 tickets, what's the probability that you'll win the raffle?
| 1% | |
| 8% | |
| 10% | |
| 9% |
You have 27 out of the total of 300 raffle tickets sold so you have a (\( \frac{27}{300} \)) x 100 = \( \frac{27 \times 100}{300} \) = \( \frac{2700}{300} \) = 9% chance to win the raffle.
How many 7-passenger vans will it take to drive all 77 members of the football team to an away game?
| 11 vans | |
| 4 vans | |
| 7 vans | |
| 8 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{77}{7} \) = 11
4! = ?
3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
|
4 x 3 |
|
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.
