Your teacher is right. There is no reason to use algebra, which is misused in many problems as a shortcut, and slows the actual learning of math skills.

Here, the solution is as follows:
1. Find the volume of water in tank X.
2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
3. Find the height of water in the new tank.

1. Find the volume of water in tank X.
Volume = 32*20*39.5=25280 cm^3

2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
Total base area = 32*20 + 30*16 + 20*8 = 640+480+160 = 1280 cm^2

3. Find the height of water in the new tank
Height = Volume / base area
= 25280 / 1280
= 19.75 cm

In 1970, a record 1.5 inches of rain fell in one minute at Brasse Terre, Guadalupe in the Caribbean. At this rate how much rain fell in 3 seconds or 0.05 of a minute? A 3 inches... B 0.075 inch... C 0.75 inch... D 30 inch. Pick one. Evan chose D as the correct answer. How did he get that answer?

Answer:

$0.075 inches$

Option B is correct.

Step-by-step explanation:

Given.

The rain fall rate is 1.5 inches per minute.

How much rain fall in 3 second or 0.05 of minute?

First we find rain fall rate in one second.

$1.5 inch/min=\frac{1.5}{60} inch/second\\=0.025 inch/second$

So, 0.025 inches of rain fall in one second.

Therefore, the rain fall in 3 second is

$= 3\times 0.025\\=0.075 inches$

The rain fall in 3 second is 0.075 inches.

If you chose option D is correct

If the rain fall is continue to 20 min at the rate of 1.5 inches per min, then the rain fall will be 30 inches.

The rain fall in 3 second is 0.075 inches.

GCF stands for "greatest common factor". This means what is the largest quantity you can divide into 6x and 20xyz without a remainder. First see what is the biggest number you can divide 6 by and also 20 without having a remainder. Next, you should see which variables 6x and 20xyz have in common. variables are the (x,y, and z). Put these two values togther and this will be your GCF.
