Since 800 is greater than 0.8 your statement would be 800>0.8
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
$741.78
-530
I hope this helps! (^_^)
16. 5(7)+13 /8
35+13/8
48 /8
6 is the answer for 16
17. 45+40= 85
85 is the answer
18. I don’t see 18
Answer:By multiplying with (1+0.01x) where x is the percentage of increase, monthly pay rate of 21$ after marked up 78.7% and 10% profit will be $41.28.
Step-by-step explanation:
Given that pay rate is 21$ and it is marked up by 78.7% and made a 10% profit.
If any value marked up or made a profit of x% then we have to multiply with (1+0.01x) to find the new value.
New pay after 78.7% marked up using above formula is 
Now we have to use above formula again for 10% profit.
Hence new value
≈$41.28
