Answer:
565.5 in^3
Step-by-step explanation:
To find the full volume of the tank
V = l*w*h
We know 12 inches high, 14.5 inches long, and 6.5 inches wide.
Substituting in
V = 12 * 14.5*6.5
V =1131 in ^3
He is filling it 1/2 full, that would be 1/2 of the volume
1/2 V = 1131/2 = 565.5 in^3
Answer:
at least above 3$
Step-by-step explanation:
If you let the convenience fee equal x, then...
(2×17.25)+(2×1)+(2×x)= 40.50
There are 2 girls so we multiply all the charges by 2. Add them together and you'll get 40.50. Now if we solve for x, we will get the amount of the convenience fee.
2×17.25 + 2×1 + 2x = 40.50
34.50 + 2 + 2x = 40.50
36.50 + 2x = 40.50
2x = 40.50 - 36.50
2x = 4
x = 2
Each girl paid a 2 dollar convenience fee.
Given :
A building is of unknown height. At a distance of 400 feet away from the building .
An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .
To Find :
How far is the poster from the roof of the building .
Solution :
Height is given by :
( Here , 
is angle of elevation )
So , height of tower :
For height of poster :
Therefore , distance of poster from the roof of the building is :
Hence , this is the required solution .
