Let the side of the square base be x, and the height of the box be h.
<span>The material of the base is x^2, and the material of the four sides is 4xh. </span>
<span>4000 = hx^2 </span>
<span>h = 4000/x^2 </span>
<span>The total material is </span>
<span>M = x^2 + 4x(4000/x^2) = x^2 + 16000/x </span>
<span>Take the first derivative of M and set equal to 0. </span>
<span>M' = 2x - 16000/x^2 = 0 </span>
<span>Multiply by x^2: </span>
<span>2x^3 = 16000 </span>
<span>x^3 = 8000 </span>
<span>x = 20; h = 10; M = 1200</span>
Okay,
So we know how many pizzas they sold throughout the week, we add those together.
93
67
78
44
<u> 123</u>
405
You divide "405" by the amount of numbers there are.
so "5" into "405"
5 goes into 40 8 times
now we have 5 into 5 which goes 1 time.
Our answer is a solid 81.
To check our work, we can multiply 81 by 5.
5*1=5
5*8=40
405.
