Answer:
So we have an original figure with a value of 50 and then a scaled version or dilation
Hence we have a scale factor of
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:
5y + 4 and 7y + 4 - 2y
Step-by-step explanation:
Look at the second choice:-
5y + 4 and 7y + 4 - 2y
Simplifying the second expression:-
7y + 4 - 2y
= 5y + 4
So both expressions are equivalent . Therefore if you plug in 2 or 5 the results will be the same.
4: 7,14,21,28,35
6: 10,8,6,4,2
8: 9,7,5,3,1
4x+3x=42
7x=42
x=6
4(6)+3(6)=42
24+18= 42
42=42
I know it's too much but hope this helped :)
