Damon loaned Ezra $100 at an annual interest rate of 1%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $35 | |
| $126 | |
| $1 | |
| $10 |
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 = 0.01 x $100
i = $1
If there were a total of 300 raffle tickets sold and you bought 18 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 18% | |
| 17% | |
| 12% |
You have 18 out of the total of 300 raffle tickets sold so you have a (\( \frac{18}{300} \)) x 100 = \( \frac{18 \times 100}{300} \) = \( \frac{1800}{300} \) = 6% chance to win the raffle.
Monty loaned Christine $400 at an annual interest rate of 7%. If no payments are made, what is the total amount owed at the end of the first year?
| $436 | |
| $428 | |
| $420 | |
| $404 |
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 $400
i = 0.07 x $400
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $400 + $28What is \( \frac{-6c^7}{9c^2} \)?
| -\(\frac{2}{3}\)c3\(\frac{1}{2}\) | |
| -1\(\frac{1}{2}\)c5 | |
| -\(\frac{2}{3}\)c9 | |
| -\(\frac{2}{3}\)c5 |
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:
\( \frac{-6c^7}{9c^2} \)
\( \frac{-6}{9} \) c(7 - 2)
-\(\frac{2}{3}\)c5
