pool has 45000 gallons.  It loses 780 gallons per hour, so the amount at any given time:

45000 - 780h, where h is the number of hours.

The chemical could be added once the amount of gallons in the pool hits 15000. So the equation to solve:

45000 - 780h = 15000

solve:

30000 = 780h

38.46 = h

It will take about 38.46 hours before chemical could be added.  It will not take longer than 2 days because 2 days is 48 hours, and we only need about 38 hours.

The softball team is selling hats. John bought 3 for $24.00. Stacey bought 5 for $40.00. Jim bought 2 for $16.00.
iren2701 [21]

The value of the hats bought by John, Stacey, and Jim are $8 per hat. This shows a proportional relationship.

<h3>What is a proportional relationship?</h3>

It should be noted that a proportional relationship is one where it van be expressed as y = kx.

In this case, John bought 3 for $24.00. This will be:

= $24 / 3

= $8 per hat

Stacey bought 5 for $40.00. This will be:

= $40 / 5

= $8 per hat

Jim bought 2 for $16.00. This will be:

= $16/2

= $8 per hat

Therefore, it's a proportional relationship.

Simplify the expression.
notsponge [240]
The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
