Step-by-step explanation:
500 cubic feet of 1/2-inch thick stainless steel plates will weigh the same no matter what dimensions are use for area and height of tank.
A 5 foot by 5 foot area 20 feet high (500 cubic feet) will weigh just as much as a 10 foot by 10 foot area 5 feet high (also 500 cubic feet) since you are using the same amount of material for the whole tank. Only possible change in weight of tank is the use of welding material and how evenly and good the welder is at welding stainless steel.
This is called the "Additive Identity Property (of Addition)". Any number plus or minus 0 is still that number.


This is reflected in the second equation here.
When estimating, you want to round the dividend and the divisor to the nearest time table number (i.e. 5700 --> 5400). Finding the quotient is easier when you estimate. Writing the remainder as a fraction is simple. First, get your remainder and your divisor, then make it to a fraction.
ex:
If you get a remainder of 3, and have a divisor if 12, your remainder would be 3/12, or 1/4.
first divide by 3
y = -2/3x +3
y equals negative two-thirds x plus three
