1% = 36000÷20= 1800
100% = 100× 1800= 180000
the dollar amount of the retail price of his recordings is $ 180000.
Let x represent the side length of the base.
The area of the base and roof are each x^2, so their cost together will be
.. (8 +9)x^2 = 17x^2
The height of the shed will be 125/x^2, so the area of one side will be
.. (125/x^2)*x*8.50
and the area of all four sides will be
.. 4*125/x*8.50 = 4250/x
So, the total cost is the cost of top and bottom together with the cost of the sides:
.. cost = 17x^2 +4250/x
This is minimized when its derivative with respect to x is zero.
.. d(cost)/dx = 0 = 2*17x -4250/x^2
.. 4250/34 = x^3
.. x = ∛125 = 5
The most economical shed is a 5 ft cube.
Answer:
(t+1)(t^2+1)
Step-by-step explanation:
t^3+t^2+t+1
(t+1)(t^2+1)
(6x(7+5))+3
(6x12)+3
72+3 = 75
C = 2pi*r
If we rearrange the terms to make r the subject,
We get r = C/2*pi
Hope it helps :)
