Answer:

Option B.

Step-by-step explanation:

We need to find the approximate surface-area-to-volume ratio of a softball.

Surface area of sphere is

A=4\pi r^2

where, r is the radius of sphere.

Volume of sphere is  

V=\dfrac{4}{3}\pi r^3

where, r is the radius of sphere.

The ratio of surface-area-to-volume is

Ratio=\dfrac{A}{V}=\dfrac{4\pi r^2}{\frac{4}{3}\pi r^3}=\dfrac{3}{r}

It is given that the radius of the ball is 2 inches.

Ratio=\dfrac{A}{V}=\dfrac{3}{r}=\dfrac{3}{2}=1.5

Therefore, the correct option is B.

5•x+5 - (5x + 25)
sukhopar [10]
Ok, so you have your equation, 5·x+5-(5x+25).
First, do the prathases, so you have, 5x+5-5x-25.(5·x also means 5x)
Now, you need to combine like terms, and through that the xs cancel out, so you are left with -20 as you answer.
