Answer:
The width of the floor is 10 ft.
Step-by-step explanation:
First, you have to form expressions of width and length in terms of w. With the given information :
width = w ft
length = (w - 2) ft
Given that the area of rectange is A = length × width so you have to subtitute the expressions and value into the formula :
A = l × w
80 = (w - 2) × w
w(w - 2) = 80
w² - 2w = 80
w² - 2w - 80 = 0
(w + 8)(w - 10) = 0
w + 8 = 0
w = -8 (rejected)
w - 10 = 0
w = 10
Answer:
Step-by-step explanation:
The angles between the parallel sides add up to 180 degrees.
So 180-70 = 110 degrees.
Answer:
<h2><em><u>
11.2 - B to C</u></em></h2><h2><em><u>
12 - B to A</u></em></h2><h2><em><u>
8.8 - A to C</u></em></h2>
You have to multiply all the sides by 4.
B to C = 2.8*4
2.8 * 4 = 11.2
B to A = 3*4
3*4 = 12
A to C = 2.2*4
2.2*4 = 8.8
Hope this helped!
Step-by-step explanation:
To find unit rate
1 bag = 36÷ 3 = 12
So unit rate = $12
