Answer:

C. x=15

Step-by-step explanation:

Use the Pythagorean Theorem:

$a^{2} +b^{2} =c^{2}$

Plug in the known values:

$9^2+12^2=c^2$

Simplify:

$81+144=c^2$

Solve:

$255=c^2$

$\sqrt{225} =c^$

$15=c$

Answer:

$Q=\frac{40}{y-16}$

$Q=10$

Step-by-step explanation:

Let the quotient be represented by 'Q'.

Given:

The difference of a number 'y' and 16 is $y-16$

Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is $y-16$ . So, we divide both these terms to get an expression for 'Q'.

The quotient of 40 and $y-16$ is given as:

$Q=\frac{40}{y-16}$

Now, we need to find the quotient when $y=20$ . Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,

$Q=\frac{40}{20-16}\\Q=\frac{40}{4}=10$

Therefore, the quotient is 10, when the value of 'y' is 20.
