Answer:
5/6
Step-by-step explanation:
Addition or subtraction of fractions requires a common denominator. The value 3/3 can be multiplied by 2/2 to give 6/6, which has the same denominator as the other fraction.
Answer:
<em>Volume = 36.4 m^3 or 9616.6 gallon</em>
<em>weight = 18025.47 N or 80213.33 lbs</em>
<em></em>
Step-by-step explanation:
The complete question is
A small family home in Tucson, Arizona, has a rooftop area of 1967 square feet, and it is possible to capture rain falling on about 56% of the roof. A typical annual rainfall is about 14 inches. If the family wanted to install a tank to capture the rain for an entire year, without using any of it, what would be the required volume of the tank in m3 and in gallons? How much would the water weigh when the tank was full (in N and in lbf)?
The area of the roof = 1967 ft^2
Area of water to be possibly captured = 56% of 1967 ft^2 = 0.56 x 1967 = 1101.52 ft^2
Rainfall depth = 14 inches = 14/12 ft = 1.167 ft
Volume of water = (area of water) x (depth of water) = 1101.52 ft^2 x 1.167 ft = <em>1285.47 ft^3</em>
<em></em>
35.315 ft^3 = 1 m^3
1285.47 ft^3 = m^3
==> 1285.47/35.315 = <em>36.4 m^3</em>
<em></em>
1 ft^3 = 7.481 gallon
1285.47 ft^3 = gallon
==> 1285.47 x 7.481 = <em>9616.6 gallon</em>
<em></em>
Weight of water W = ρv
where ρ is the density of water = 62.4 lbs/ft^3
v is the volume of water = 1285.47 ft^3
substituting values,
W = 62.4 x 1285.47 = <em>80213.33 lbs</em>
but,
1 lb = 4.45 N
therefore,
80213.33 lbs = 80213.33/4.45 = <em>18025.47 N</em>
