Just divide 27.040 divided by 40 equals 0.648 witch means 648 $ per hour well i think
If a number is 75% of 85, the value of the number is 63.75.
<h3>What is 75% of 85?</h3>
Let the number the represented by 'x'
Such that; 75% of 85 = x
Solve for x.
75% of 85 = x
75% × 85 = x
75/100 × 85 = x
x = ( 75 × 85 )/100
x = 6375/100
x = 63.75
Therefore, if a number is 75% of 85, the value of the number is 63.75.

(ab+3)(ab−3)
=(ab+3)(ab+−3)
=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)

=a^2b^2−9
A = s2 (Area of a square is its side squared)
P = 4s (perimeter of a square is a side times 4)
A = 324 (the area of this square is 324 ft2)
fencing = $7 per foot
Let's find the side through the area. Find the root:
√324 = √s2
18 = s
Now the perimeter:
P = 4 * 18 = 72
Now to find how much the fencing will cost:
72 * 7 = 504
