Answer:

a) y = -500x + 130,000

b)67,500 gallons remaining

c) 260 hours

Step-by-step explanation:

Since water is being removed at a rate of 500 gallons per hour, the slope would be a negative.

a) y = -500x + 130,000

For<u> part b</u> input 125 for x:

y = -500(125) + 130,000

y = 67,500

There are 67,500 gallons remaining

For part c we are solving for the x intercept

0 = -500x + 130,000

Subtract 130,000 from both sides

-130,000 = -500x

x = 260

It will take 260 hours for the pool to completely drain

A bolt has 6 1/2 turns per inch. How many turns would be in 2 1/2 inches of threads?
Reika [66]

There would be 41 1/4 turns in 2 1/2 inches of threads.

Given, number of turns a bolt has = 16 1/2 turns per inch.

per inch bolt turns = 16 1/2 =33/2

how many turns would be there in 2 1/2 inches of threads = ?

Threads Per Inch, or TPI, is a measure of how many threads are found in one inch along a fastener's length. American fasteners are the only ones that employ TPI. Typically, the thread count is higher for smaller fasteners since they have finer threads. Just as the name implies, the Threads Per Inch (TPI) refers to the number of threads that run the length of a screw for one inch. The TPI of a screw can be easily calculated by simply counting the threads and dividing the total length.

so, 5/2 inches bolt turns =33/2 x 5/2

=165/4

hence 41 1/4 turns

Therefore, 2 1/2 inches of threads have 41 1/2 turns.
