Answer: (0.120)(x) = 78 ; x is 65
Step-by-step explanation:
I am quite confused what this problem asks about.
We are given that:
4,000 / 10 is equal to hundred / 10
I believe this problem is asking us how much in hundreds
is 4,000
Therefore the answer is: 40
Such that:
<span>4,000 / 10 = 40 hundreds / 10</span>
We know that
area of the composite figure=area of the rectangle+area of semicircle
area of rectangle=b*h
b=10 ft
h=6 ft
area rectangle=10*6----> 60 ft²
area of semicircle=pi*r²/2
r=6/2----> 3 ft
area of semicircle=pi*3²/2-----> 14.13 ft²
area of the composite figure=[60+14.13]-----> 74.13 ft²-----> 74 ft²
the answer is
74 ft²
