which of the following could you use to find 40% of 32?

\frac{40}{100}*32

\frac{2}{5}*32

0.4*32

step-by-step explanation:

we know that

40\%=\frac{40}{100}=\frac{2}{5}=0.4

therefore

40\% of 32

is equal to

\frac{40}{100}*32=12.8

\frac{2}{5}*32=12.8

0.4*32=12.8

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

$5.41
