I've tried this many times, but I keep getting a really big answer. A rancher wants to fence in an area of 2500000 square feet in a rectangular field and then divide it in half with a fence down the middle parallel to one side. What is the shortest length of fence that the...

calculus?
assuming the garage will be one of the long sides (otherwise lots of extra fencing will be used), then if the long side is x, the short side will be 50/x. So, the amount of fence, f, is f(x) = x + 2(50/x) = x + 100/x df/dx = 1 - 100/x^2 we want minimum fence, so df/dx = 0: x...

the square has to be at least 10x10, using 40 yds of fence. That leaves 240 yds for the rectangle, so X+2X<=120, or X <= 40. If X = 40, 2X = 80, so area = 3200 If 2X^2 = 800, X=20, so 20 <= X <= 40 As X increases from 20 to 40, the area increases ...

Change these fractions to equivalent fractions with the same denominator. 1/2 = 60/120 7/8 = 105/120 9/10 = 108/120 1/3 = 40/120 3/5 = 72/120 1/4 = 30/120 Now you can arrange them in order.
