Answer:
15.7 - 2a
Step-by-step explanation:
Perimeter = 15.7 inches
2a + b = 15.7
b = 15.7 - 2a
The area of the roof is 1984 sq. ft. 1984 square feet of roofing is needed for the roof of a building that is 32 ft wide and 62 ft long.
Given, the length of the roof is 62 ft long and the width of the roof is 32 ft wide. Therefore, the area of the roof is length * width.
Area of the roof = length of the roof * width of the roof
Area = 62 ft * 32 ft
Area = 1984 sq. ft
Here, also given the slope of the roof is 1:2 which indicates the ratio of rise and run.
Slope of the roof = Rise / Run = 1 / 2
Then, the slope factor is
=
= 0.04167

Answer:
0.29M + 84
Step-by-step explanation:
The mileage charge is multiplied by the number of miles and added to the basic daily charge to get the total cost for one day:
one-day cost = 0.29M + 84.00
Answer:
x = $3, or x = $11
Step-by-step explanation:
The equation given is
where
- P(x) is the profit, and
- x is the app price
<u>We want app prices (x's) when profit (P(x)) is 0, so plugging in into the equation:</u>

<em>It means (x-3) = 0 OR (x-11) = 0</em>
So, x = 3, or 11
Answer:
Number of apples = 6
Number of oranges = 5
Step-by-step explanation:
At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.
Let
Number of apples = x
Number of oranges = y
x + y = 11 (1)
0.80x + 0.95y = 9.55 (2)
From (1)
x = 11 - y
Substitute into (2)
0.80x + 0.95y = 9.55 (2)
0.80(11 - y) + 0.95y = 9.55
8.8 - 0.80y + 0.95y = 9.55
- 0.80y + 0.95y = 9.55 - 8.8
0.15y = 0.75
y = 0.75/0.15
y = 5
Substitute y = 5 into (1)
x + y = 11 (1)
x + 5 = 11
x = 11 - 5
x = 6
Number of apples = 6
Number of oranges = 5
