24/36 or simplified 2/3 of a yard
Step-by-step explanation:
Answer:
base side = 20cm
height = 40 cm
minimum cost = $7200
Step-by-step explanation:
Let x (cm) be the base side and h (cm) be the height of the box. Since the volume of the box must be 16000 cubic cm, we have:
The areas of the top and bottom is
And so their cost is:
The areas of the sides is
And so their cost is:
We can substitute into the equation above to get
So the total cost of the bases and the sides:
This is the function we would want to minimize. We can start by taking the 1st derivative, and set it to 0
So the height would be
So the minimum total cost would be
There is a total of 60 cars in the parking lot.
21 x 100 = 2100
2100/ 35 = 60.
Distribute the 2 among the terms inside the parentheses. in other words just multiply the 2 with the numbers inside the parentheses.
