Answer: if you had a circle of radius r, then the 2*radius is equal to the diagonal of the square. So the length of the side is calculated from the Pythagorean theorem since squares have right triangles in them: (2r)^2=2(l^2). Sqrt(2*r^2)=l where l is the length of the side of the square.
Step-by-step explanation:
Let x = # of monthly fee
f(x) = (50x + 30)/x
average cost will be below 56 for how many months?
(50x + 30)/x = 56
50x + 30 = 56x
56x - 50x = 30
6x = 30
x = 5
answer:
the average cost will be below $56 for 5 months
