Answer 1
Answer:

Hey!

-------------------------------------------------

Prefect Pipes: 120 + 40 = $160 (y-intercept)

No Leaks Here: 50 + 60 = $110 (y-intercept)

-------------------------------------------------

Hour #1:

Prefect Pipes: 160 + 40 = $200

No Leaks Here: 110 + 60 = $170

Hour #2:

Prefect Pipes: 200 + 40 = $240

No Leaks Here: 170 + 60 = $230

Hour #3:

Prefect Pipes: 240 + 40 = $280

No Leaks Here: 230 + 60 = $290

-------------------------------------------------

$280 < $290

After 3 hours Perfect Pipes is less expensive than No Leaks Here!

-------------------------------------------------

Hope This Helped! Good Luck!
Answer 2
Answer:

Answer:  After 3.5 hours, Perfect pipes is less expensive than No leaks here.

Step-by-step explanation:

Let the number of hours be 'h'.

So, Perfect pipes charges $120 plus $40 per hour.

so, our equation becomes,

f(h)=120+40h

No leaks charges $50 plus $60 per hour.

So, our equation becomes,

g(h)=50+60h

According to question, Perfect pipes is less expensive than no leaks here after how many hours.

So, it becomes,

120+40h<50+60h\n\n120-50<60h-40h\n\n70<20h\n\n(70)/(20)<h\n\n3.5<h

Hence, After 3.5 hours, Perfect pipes is less expensive than No leaks here.

The volume of the cylinder to the nearest hundredth is  1,846.32 cubic feet.

A cylinder is a three-dimensional shape. It is a prism with circular edges.

Volume of a cylinder = πr²h

  • π = pi = 3.14
  • r = radius
  • h = height

3.14 x 7² x 12 = 1,846.32 cubic feet

Please find attached an image of a cylinder. To learn more about to determine the volume of a cylinder, check: brainly.com/question/12763699
Find the area of the base of the cylinder, 

A = \pi x 49

Then multiply by the height of the cylinder,

49\pi x 12 = 588\pi

then insert 3.14 for pi

588 x 3.14 = 1,846.32 cubic feet
