The relation between a and s is given to be:
a = 640s
where,
a = number of acres
s = number of square miles
We are to find the number of acres for 7.5 square miles.
This means, s = 7.5
Using the value in the formula, we get:
a = 640 x 7.5 = 4800 acres
So the answer to this question is option B

Answer:
2x + 1/2 sq. ft
Step-by-step explanation:
Surface area = 2(lw+wh+lh)
Given
length l = x ft
width w = 1/2 ft
height h = 1/2ft
Substitute
Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))
Surface area = 2(x/2+1/4+x/2)
Surface area = 2(2x/2 + 1/4)
Surface area = 2(x + 1/4)
Surface area = 2x + 2/4
Surface area = 2x + 1/2 sq. ft
