Damon loaned Roger $1,100 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?
| $77 | |
| $28 | |
| $56 | |
| $88 |
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 $1,100
i = 0.07 x $1,100
i = $77
9 members of a bridal party need transported to a wedding reception but there are only 2 3-passenger taxis available to take them. How many will need to find other transportation?
| 8 | |
| 4 | |
| 3 | |
| 5 |
There are 2 3-passenger taxis available so that's 2 x 3 = 6 total seats. There are 9 people needing transportation leaving 9 - 6 = 3 who will have to find other transportation.
Which of the following is a mixed number?
\(1 {2 \over 5} \) |
|
\({7 \over 5} \) |
|
\({5 \over 7} \) |
|
\({a \over 5} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
What is \( \frac{3c^6}{7c^4} \)?
| \(\frac{3}{7}\)c2 | |
| \(\frac{3}{7}\)c10 | |
| 2\(\frac{1}{3}\)c2 | |
| \(\frac{3}{7}\)c24 |
To divide terms with exponents, the base of both exponents must be the same. In this case they are so divide the coefficients and subtract the exponents:
\( \frac{3c^6}{7c^4} \)
\( \frac{3}{7} \) c(6 - 4)
\(\frac{3}{7}\)c2
