12 members of a bridal party need transported to a wedding reception but there are only 4 2-passenger taxis available to take them. How many will need to find other transportation?
| 9 | |
| 4 | |
| 2 | |
| 8 |
There are 4 2-passenger taxis available so that's 4 x 2 = 8 total seats. There are 12 people needing transportation leaving 12 - 8 = 4 who will have to find other transportation.
Solve 5 + (4 + 4) ÷ 5 x 4 - 32
| 2\(\frac{2}{5}\) | |
| 4 | |
| \(\frac{2}{9}\) | |
| \(\frac{4}{5}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
5 + (4 + 4) ÷ 5 x 4 - 32
P: 5 + (8) ÷ 5 x 4 - 32
E: 5 + 8 ÷ 5 x 4 - 9
MD: 5 + \( \frac{8}{5} \) x 4 - 9
MD: 5 + \( \frac{32}{5} \) - 9
AS: \( \frac{25}{5} \) + \( \frac{32}{5} \) - 9
AS: \( \frac{57}{5} \) - 9
AS: \( \frac{57 - 45}{5} \)
\( \frac{12}{5} \)

Charlie loaned Frank $700 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?
| $35 | |
| $2 | |
| $1 | |
| $108 |
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 $700
i = 0.05 x $700
i = $35
What is the next number in this sequence: 1, 4, 10, 19, 31, __________ ?
| 46 | |
| 43 | |
| 52 | |
| 40 |
The equation for this sequence is:
an = an-1 + 3(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 3(6 - 1)
a6 = 31 + 3(5)
a6 = 46
What is \( \frac{3}{5} \) x \( \frac{4}{8} \)?
| \(\frac{8}{63}\) | |
| 2\(\frac{2}{5}\) | |
| \(\frac{3}{10}\) | |
| \(\frac{2}{9}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{5} \) x \( \frac{4}{8} \) = \( \frac{3 x 4}{5 x 8} \) = \( \frac{12}{40} \) = \(\frac{3}{10}\)
