between 50 and 100 it has 5 lines. so, 100-50 = 50 and divide to 5. because there are 5 parts. 50/5 = 10.1 line = 10. 50 + 10 + 10 = 70.ans: 70
You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3
Answer:
129 square foot
Step-by-step explanation:
<u>Step 1: Convert height of the door to inches</u>
Height of the door = 10 feet 8 inches
1 feet = 12 inches
10 feet = y inches
<em>Cross Multiply</em>
y = 120 inches
Height of door in inches = 120 + 8 =128 inches
<u>Step 2: Find the surface area of one side of the door</u>
Surface area = length x width
length = 128 inches
width = 145 inches
Surface area = 128 x 145
Surface area = 18560 inches
<u>Step 3: Convert surface area from inches to square foot</u>
Surface area = 18560 inches
1 square foot = 144 inches
y = 18560 inches
<em>Cross multiply</em>
144y = 18560
y = 18560/144
y = 128.89 rounded off to 129 square foot.
Therefore, you should report 129 square foot surface area to the hardware store.
