Hi there! :)

Answer:

$\huge\boxed{\frac{17}{7} }$

Given ratio of 51 boys to 21 girls:

Write as a ratio:

$51 : 21$

Divide both terms by GCF, or 3:

$\frac{51}{3} : \frac{21}{3}$

$17 : 7$ or $\frac{17}{7}$

Therefore, the ratio is 17 boys to 7 girls, or $\boxed {\frac{17}{7}}$

Answer: 3. 4 $\sqrt{13}$ 4. $\sqrt{225}$

Step-by-step explanation:

8^2 + 12^3 = c^2

64 + 144 = c^2

208 = c^2

√208

$4\sqrt{13}$

The final answer is the square root of 208

8^2 + b^2 = 17^2

64 + b^2 = 289

-64 64

b^2 = 225

$\sqrt{225}$

Assuming x and y are two odd numbers and x/y is an integer. Which of the following statements are true?

yan [13]

9514 1404 393

Answer:

C: 2 and 3 only.

Step-by-step explanation:

We know the sum or difference of two odd numbers is even, eliminating choices (1) and (4).

The product of two odd numbers is odd, so (2) is one of the true statements.

Let x/y = k, where x and y are both odd. Then x = ky. If k is even, then x is even, a contradiction. So, k must be odd. The integer ratio of two odd numbers is odd, so (3) is one of the true statements.

Only statements (2) and (3) are true.
