The answer is $911.68.

After a little research on the internet, I found the design of the window.
First, you need to find the area of the window which is a composite figure made up of a rectangle and a circle. So, the total area (A) is the sum of the area of the rectangle (A1) and the area of the circle (A2).

Area of the rectangle with length l and width w is:
A = l * w
According to the image, l = 5 ft and w = 4 ft.
A1 = 5 * 4 = 20 ft²

Area of the circle with radius r is:
A = r²π
According to the image, r = 2 ft.
A2 = 2² * 3.14 = 12.56 ft²

The area of the window is:
A = A1 + A = 20 ft² + 12.56 ft² = 32.56 ft²

<span>The glass costs $28 per square foot, so to replace the glass will cost:
</span>32.56 ft² * $28/ft² = $911.68

A cafeteria serves 120 pints of milk each day . how many quarts of milk does the cafetieria serve each day
frosja888 [35]

For this case we have by definition:

1 Pint is equal to 0.5 quart

We must indicate how many quarts there are in 120 pints.

Making a rule of three we have:

1 pint --------------------> 0.5 quart

120 pints -------------> x

Where the variable "x" represents the number of quarts equivalent to 120 pints.

x = \frac {120 * 0.5} {1}\\x = 60

Thus, 120 pints are equivalent to 60 quarts

Option C
