Of all numbers whose sum is 70 , find the two that have the maximum product. That is, maximize Q=xy where x+y=70. The values of x and y that have the maximum product are x= and y=.

A rectangular box with a volume of 475ft3 is to be constructed with a square base and top. The cost per square foot for the bottom is 20ϕ, for the top is 10ϕ, and for the sides is 2.5ϕ. What dimensions will minimize the cost? What are the dimensions of the box? The length of one side of the base is The height of the box is (Round to one decimal place as needed.)
