What is \( \frac{16\sqrt{24}}{8\sqrt{8}} \)?
| \(\frac{1}{2}\) \( \sqrt{3} \) | |
| 2 \( \sqrt{\frac{1}{3}} \) | |
| 3 \( \sqrt{\frac{1}{2}} \) | |
| 2 \( \sqrt{3} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{16\sqrt{24}}{8\sqrt{8}} \)
\( \frac{16}{8} \) \( \sqrt{\frac{24}{8}} \)
2 \( \sqrt{3} \)
If there were a total of 300 raffle tickets sold and you bought 15 tickets, what's the probability that you'll win the raffle?
| 18% | |
| 5% | |
| 9% | |
| 2% |
You have 15 out of the total of 300 raffle tickets sold so you have a (\( \frac{15}{300} \)) x 100 = \( \frac{15 \times 100}{300} \) = \( \frac{1500}{300} \) = 5% chance to win the raffle.
Simplify \( \frac{36}{44} \).
| \( \frac{7}{18} \) | |
| \( \frac{7}{16} \) | |
| \( \frac{9}{11} \) | |
| \( \frac{9}{20} \) |
To simplify this fraction, first find the greatest common factor between them. The factors of 36 are [1, 2, 3, 4, 6, 9, 12, 18, 36] and the factors of 44 are [1, 2, 4, 11, 22, 44]. They share 3 factors [1, 2, 4] making 4 their greatest common factor (GCF).
Next, divide both numerator and denominator by the GCF:
\( \frac{36}{44} \) = \( \frac{\frac{36}{4}}{\frac{44}{4}} \) = \( \frac{9}{11} \)
A tiger in a zoo has consumed 16 pounds of food in 2 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 72 pounds?
| 9 | |
| 7 | |
| 5 | |
| 4 |
If the tiger has consumed 16 pounds of food in 2 days that's \( \frac{16}{2} \) = 8 pounds of food per day. The tiger needs to consume 72 - 16 = 56 more pounds of food to reach 72 pounds total. At 8 pounds of food per day that's \( \frac{56}{8} \) = 7 more days.
Charlie loaned Monty $1,400 at an annual interest rate of 9%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $18 | |
| $126 | |
| $56 | |
| $1 |
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 $1,400
i = 0.09 x $1,400
i = $126
