What is 2z7 x 5z7?
| 10z49 | |
| 10z14 | |
| 7z49 | |
| 10z0 |
To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:
2z7 x 5z7
(2 x 5)z(7 + 7)
10z14

Charlie loaned Monty $500 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?
| $28 | |
| $2 | |
| $36 | |
| $25 |
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 $500
i = 0.05 x $500
i = $25
A bread recipe calls for 3\(\frac{3}{8}\) cups of flour. If you only have \(\frac{3}{8}\) cup, how much more flour is needed?
| 2\(\frac{1}{4}\) cups | |
| 1\(\frac{7}{8}\) cups | |
| \(\frac{7}{8}\) cups | |
| 3 cups |
The amount of flour you need is (3\(\frac{3}{8}\) - \(\frac{3}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{27}{8} \) - \( \frac{3}{8} \)) cups
\( \frac{24}{8} \) cups
3 cups
