I am having trouble with this word problem. I have read it over many times and am very confused. Can someone please help me?

The production cost of a job depends in part on the accuracy required. On most sheet metal jobs, an accuracy of 1,2, or 0.1 mils is required. A mil is (1/1000), (2/1000), or (1/10,000) inch larger or smaller than the blueprint states. Industrial jobs often require a higher degree of accuracy.

a. Write inequalities that moels the possible dimensions of a part that is supposed to be 8 inches by 4.25 inches if the accuracy required is 2 mils.

b. Graph the region that shows the satifactory dimensions for the part.

I appreicate any help you can give me

How do you calculate the the area and perimeter of an irregular polygon knowing the length of sides

I am looking for how quickly can the tank be completely drained.

Maybe this would help

The velocity = 8.02 times the square root of the fluid level (in feet) remaining in the tank

The amount of fluid drained through the hole (in one second) is velocity multiplied by the area of hole.

Can anyone help with this one.

You want to drill a hole in the tank that will take the most time to drain, and then drill a hole in the tank that will take the second most time to drain.

Tank Height is 20 feet, tank diameter is 8 feet, hole diameter of 2 inches. It takes 42 minutes and 45 seconds to drain the tank.

If someone could just help me set up an equasion that would be wonderful

Thanx for any help
