The Lamaster family is a family of five people. They have used 4,885.78 gallons of water so far this month. They cannot exceed 7
oksian1 [2.3K]

Let X be the amount of water one person can use.

Multiply that by 5 people to get 5X

That amount plus what they already used ( 4885.78) needs to be less than or equal to the amount they are limited to ( 7250.50 ).

Now write out the equation to get : 5x + 4885.78 ≤ 7250.50

A round baby pool holds 48.2 cubic feet of water. If the pool has a radius of 3.2 feet, what is the height of the pool in feet?
Daniel [21]
The formula for the volume of a cylinder is
  V = π×r²×h

Substitute your given numbers and solve for h.
  48.2 ft³ = π×(3.2 ft)²×h
  h = (48.2 ft³)/(π×(3.2 ft)²)
  h ≈ 1.5 ft

The height of the pool is about 1.5 feet.

Suppose that the functions h and f are defined as follows. h(x) =3/x, x notequalto 0 f(x) = x^2 - 1 Find the compositions h comp
Klio2033 [76]

Answer:

hf(x) = 3/(x² - 1)

fh(x) = (9 - x²)/x²

Step-by-step explanation:

h(x) = 3/x

f(x) = x² - 1

h(f(x)) = 3/f(x)

hf(x) = 3/(x² - 1)

f(h(x)) = (h(x))² - 1

= (3/x)² - 1

= 9/x² - 1

fh(x) = (9 - x²)/x²

Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease. Increasing 20 to 40 is the
STALIN [3.7K]

Answer:

To find increase/decrease, divide the starting number by the ending number.

<u>40 to 20</u>

20 ÷ 40 = 0.5

0.5 can be represented by 50%.

<u>20 to 40</u>

40 ÷ 20 = 2

2 can be represented by 200%. This is why decreasing 40 to 20 is a 200% increase. In the wording, it says it's a 100% increase. That would be 20 plus 20 times 1 (which is the same as 100%) which is 40.
