12 and 2 are the two factors
Answer:
Part A:
Blueprint 10 inches ⇒ Actual 35 feet
Blueprint 20 inches ⇒ Actual 70 feet
Part B:
The cost of the cover is $857.5
Step-by-step explanation:
Part A:
∵ The drawing scale is 2 inches for 7 feet
∵ The length = 20 inches and the width = 10 inches
∴ The actual length = (20 × 7) ÷ 2 = 70 feet
∴ The actual width = (10 × 7) ÷ 2 = 35 feet
Part B:
∵ The cost per square foot = $0.35
∵ The area of the pool = 70 × 35 = 2450 feet ²
∴ The cost of the cover = 2450 × 0.35 = $857.5
Answer:
slope: 5/7
0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714
Answer: 11.05
Step-by-step explanation:
