Answer:
1046 pounds
Step-by-step explanation:
The volume of the hemisphere is given by the formula ...
V = 2/3πr³
where r is the radius, or half the diameter.
The radius is (4 ft)/2 = 2 ft, so the volume of the tank is ...
V = (2/3)π(2 ft)³ = 16/3π ft³ ≈ 16.755 ft³
Then the weight of the water in the tank is ...
(16.755 ft³)(62.4 lb/ft³) ≈ 1045.52 lb
The total weight of the water is about 1046 pounds.
Set this up as follows...
12x - 10 = 7x + 20
solve for x
X is 6
sub VW=7X with 7•6
VW=42
check by subbing also for UW
72 - 10 is 62
uV plus VW equals 62. it checks out.
Jenna has 3 red balloons and 5 blue balloons.
The ratio of the number of red balloons to the number of blue balloons is
3:5
She adds 2 red balloons and removes 1 blue balloon.
The new ratio of the number of red balloons to the number of blue balloons is
3+2:5-1
5:4
The volume of rectangular prism is 90m
