Answer:
1312.5 cubic feet
Step-by-step explanation:
Let the swimming pool be a rectangular prism
The volume of a rectangular prism is:
Volume = length * width * depth
Length = 25 (given)
Width = 15 (given)
The depth is 4ft, but they want the volume when water is 6 inches FROM THE TOP, that is, out of 4 feet, 6 inches (1/2 feet) IS NOT FILLED. So the depth of water is
4 - 1/2 = 3.5 feet
So, we can say
Depth = 3.5 (found)
Hence, the volume would be:
Volume = 25 * 15 * 3.5 = 1312.5 cubic feet
Answer:
30 centimeters
Step-by-step explanation:
You have to find the scaling of the lengths first, and to do that, you divide the 20 by 8, which would be 2.5. After, you multiply 2.5 by 12 to get your answer.
Answer:
17.0
Step-by-step explanation:
right angle with angles 45, 45 and 90
SOHCAHTOA
cos 45 = A/H
Cos 45 = 12/r
r= 12/cos 45
r= 16.97
Answer:
(3,0) reflection on x axis (3,0)
(3,0) reflection on y axis (-3,0)
You would solve it in two parts.
4*n = 44 Divide by 4
4n/4 = 44/4
n = 11
=============
z^m * z^2 = z^9
When the bases are the same (on the left) the powers on the left add
m + 2
The powers on the left side of the equation are the same as the powers on the right when the bases are the same.
m + 2 = 9 Subtract 2 from both sides.
m + 2 - 2 = 9 - 2
m = 7
