Step-by-step explanation:
40-6
34
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
Answer:
y=5x+6
Step-by-step explanation:
use the equation y=mx+b
m=slope and b=y-intercept
You can go ahead and insert 5 into the equation because we know that the slope of the line is 5. for b. the y-intercept, we know that points are in (x,y) form so we can infer that -3 is the x and 6 is the y. from here you can plug in the number 6 for b and there's your equation. hope this helps!!
