Answer:
198571428571/10000000000
Step-by-step explanation:
You simply convert the decimal.
2x + 7 = 15
Get 2x by itself
Take away 7 from both sides.
2x = 8
Divide both sides by 2, or multiply both sides by 0.5.
x = 4.
Your answer is C.)
see the picture in the attached figure
step 1
find the area of rectangle
A=110*43
A=4730 yd²
step 2
find the area of semicircles
we know that two semicircles is equal to one circle
so
Area of the circle=pi*r²
r=43/2
r=21.5 yd
A=pi*21.5²
A=462.25 *pi yd²-------->1,451.465 yd²
total area=area rectangle + area of circle
total area=4,730+1,451.465---------> 6,181.465 yd²
step 3
find the cost
$0.12 per square yard
6,181.465*0.12=$741.78
therefore
the answer is
$741.78
