1. (The base on top is 15 ft.
To find the base on the bottom you have to first find the length of the right side of the triangle. 7 - 4 = 3. Then, square both sides of the triangle and add them together. 15^2 + 3^2 = 234
Next take 234 and find its square root = 15.3. The bases of the trapezoid are 15 and 15.3)
2. (Both bases and the height.)
3. (2l + 2w does not belong, all of the equations are formulas for area but that one is perimeter)
A=6,500×(1+0.07÷360)^(360×5)
A=9,223.63
Interest earned
9223.63-6500==2,723.63
9/10 + 8/100
9/10 + 2×4/25×4
Common denominator is 50.
9/10 + 2/25.
5×9/5×10 + 2×2/2×25
45/50 + 4/50
= 49/50
Here, 635/9
Nearest divisible of 9 is 630 so,
It would be: 70 * 9 + 5
In short, Your Quotient would be 70
Hope this helps!
I believe it would be 12 because 9 min divided by .75 a rotation gets 12 rotations
