Determine equivalent ratios:
First, we simplify the ratio to the least possible
By comparison with the given options, we have A and B as answer.
See Proof Below
Proof: A
Compare this to the simplified ratio (given), we have:
=
Proof B
Simplify the ratio to the least possible
Compare this to the simplified ratio (given), we have:
=
Answer:
The dimensions of swimming pool are:
Length = 26.2 feet
Width = 16.3 feet
Height = 5 feet
During a few hot weeks during the summer, some water evaporates from the pool, and Jill needs to add 8 inches of water to the depth of the pool.
We will convert 8 inches o feet.
1 inch = 1/12 feet
So, 8 inch = feet
Now we have to tell how much water will be there in 0.66 feet depth.
So, volume = cubic feet.
1 cubic feet has 7.480 gallons
So, 281.86 cubic feet will have gallons of water.
You just need a slight idea about phase shift of waves .And it's just similar like that
