What is the greatest common factor of 60 and 52?
| 3 | |
| 8 | |
| 4 | |
| 32 |
The factors of 60 are [1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60] and the factors of 52 are [1, 2, 4, 13, 26, 52]. They share 3 factors [1, 2, 4] making 4 the greatest factor 60 and 52 have in common.
A tiger in a zoo has consumed 143 pounds of food in 11 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 182 pounds?
| 3 | |
| 11 | |
| 6 | |
| 7 |
If the tiger has consumed 143 pounds of food in 11 days that's \( \frac{143}{11} \) = 13 pounds of food per day. The tiger needs to consume 182 - 143 = 39 more pounds of food to reach 182 pounds total. At 13 pounds of food per day that's \( \frac{39}{13} \) = 3 more days.
What is \( \frac{1b^6}{6b^2} \)?
| \(\frac{1}{6}\)b12 | |
| \(\frac{1}{6}\)b\(\frac{1}{3}\) | |
| \(\frac{1}{6}\)b4 | |
| 6b-4 |
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:
\( \frac{b^6}{6b^2} \)
\( \frac{1}{6} \) b(6 - 2)
\(\frac{1}{6}\)b4
What is 5\( \sqrt{6} \) x 4\( \sqrt{4} \)?
| 20\( \sqrt{6} \) | |
| 9\( \sqrt{6} \) | |
| 40\( \sqrt{6} \) | |
| 9\( \sqrt{24} \) |
To multiply terms with radicals, multiply the coefficients and radicands separately:
5\( \sqrt{6} \) x 4\( \sqrt{4} \)
(5 x 4)\( \sqrt{6 \times 4} \)
20\( \sqrt{24} \)
Now we need to simplify the radical:
20\( \sqrt{24} \)
20\( \sqrt{6 \times 4} \)
20\( \sqrt{6 \times 2^2} \)
(20)(2)\( \sqrt{6} \)
40\( \sqrt{6} \)
What is \( \frac{1}{5} \) x \( \frac{3}{5} \)?
| \(\frac{3}{5}\) | |
| \(\frac{12}{35}\) | |
| \(\frac{3}{25}\) | |
| \(\frac{1}{72}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{5} \) x \( \frac{3}{5} \) = \( \frac{1 x 3}{5 x 5} \) = \( \frac{3}{25} \) = \(\frac{3}{25}\)
