Which of these numbers is a factor of 16?
| 13 | |
| 2 | |
| 19 | |
| 16 |
The factors of a number are all positive integers that divide evenly into the number. The factors of 16 are 1, 2, 4, 8, 16.
A bread recipe calls for 2\(\frac{3}{8}\) cups of flour. If you only have 1\(\frac{1}{4}\) cups, how much more flour is needed?
| 1\(\frac{1}{8}\) cups | |
| 1 cups | |
| 2\(\frac{1}{2}\) cups | |
| 2\(\frac{3}{8}\) cups |
The amount of flour you need is (2\(\frac{3}{8}\) - 1\(\frac{1}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{19}{8} \) - \( \frac{10}{8} \)) cups
\( \frac{9}{8} \) cups
1\(\frac{1}{8}\) cups
Alex loaned Ezra $200 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?
| $20 | |
| $16 | |
| $14 | |
| $8 |
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 $200
i = 0.07 x $200
i = $14
9 members of a bridal party need transported to a wedding reception but there are only 3 2-passenger taxis available to take them. How many will need to find other transportation?
| 3 | |
| 5 | |
| 4 | |
| 6 |
There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 9 people needing transportation leaving 9 - 6 = 3 who will have to find other transportation.
What is \( \frac{35\sqrt{36}}{5\sqrt{9}} \)?
| 7 \( \sqrt{4} \) | |
| 4 \( \sqrt{7} \) | |
| 4 \( \sqrt{\frac{1}{7}} \) | |
| \(\frac{1}{7}\) \( \sqrt{\frac{1}{4}} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{35\sqrt{36}}{5\sqrt{9}} \)
\( \frac{35}{5} \) \( \sqrt{\frac{36}{9}} \)
7 \( \sqrt{4} \)
