What is \( \frac{9\sqrt{15}}{3\sqrt{5}} \)?
| 3 \( \sqrt{\frac{1}{3}} \) | |
| 3 \( \sqrt{3} \) | |
| \(\frac{1}{3}\) \( \sqrt{3} \) | |
| \(\frac{1}{3}\) \( \sqrt{\frac{1}{3}} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{9\sqrt{15}}{3\sqrt{5}} \)
\( \frac{9}{3} \) \( \sqrt{\frac{15}{5}} \)
3 \( \sqrt{3} \)
Bob loaned Latoya $700 at an annual interest rate of 6%. If no payments are made, what is the total amount owed at the end of the first year?
| $721 | |
| $749 | |
| $756 | |
| $742 |
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 = 0.06 x $700
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $700 + $42What is (c3)3?

| c0 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(c3)3If there were a total of 50 raffle tickets sold and you bought 3 tickets, what's the probability that you'll win the raffle?
| 6% | |
| 14% | |
| 10% | |
| 7% |
You have 3 out of the total of 50 raffle tickets sold so you have a (\( \frac{3}{50} \)) x 100 = \( \frac{3 \times 100}{50} \) = \( \frac{300}{50} \) = 7% chance to win the raffle.
