You are putting a rectangular hot tub on your back porch. it is 6 feet long, 5 feet wide, and 3 feet deep. how much will it cost to fill the hot tub if water costs $5 per 1000 gallons?

The cost of filling the hot tub is $3.37.

Step-by-step explanation:

Given:

You are putting a rectangular hot tub on your back porch.

It is 6 feet long, 5 feet wide, and 3 feet deep.

If water costs $5 per 1000 gallons.

Now, to find the cost to fill the hot tub.

So, to find the volume of tub first.

Length = 6 feet.

Width = 5 feet.

Height = 3 feet.

Now, we put formula to get its volume:

Volume = length × width × height

As given $5 per 1000 gallons so we get the unit rate by using unitary method:

1000 gallons of water costs $5.

1 gallon of water costs $5 ÷ 1000 = $0.005.

Now, we convert the volume of tub into gallon.

1 feet³ = 7.48052.

So, multiplying 90 feet³ by 7.48052 we get:

90 feet³ = 673.247 gallons.

Thus, the volume of tub = 673.247 gallons.

So, 1 gallon of water cost $0.005.

Thus, 673.247 gallon of water costs

=

= .

Therefore, the cost of filling the hot tub is $3.37.

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
