Malaria proved that the equation you need to add the parenthesis first
Subtract the amount you have from the amount you need:
2 cups - 1 3/8 cups
Subtract the whole cup first:
2 cups -1 cup = 1 cup
8/8 = 1
Rewrite 1 as 8/8 then subtract the 3/8 you have:
8/8 - 3/8 = 5/8
You need 5/8 cup more
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
