Perfect Pipes charges $120 plus $40 anhour to make plumbing repairs. No Leaks
Here charges $50 plus $60 an hour. For
how many hours is Perfect Pipes less
expensive than No Leaks Here?

Answers

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:  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.

If a metal sheet is 1.2mm thick how must be put together to have thickness of 1.44 cm

Answers

By stacking 12 metal sheets, each 1.2 mm thick, on top of one another, the combined thickness will be 1.44 cm (14.4 mm).

To achieve a thickness of 1.44 cm, the metal sheets must be stacked on top of each other.

Since the thickness of each individual metal sheet is 1.2 mm, we need to find the number of sheets required to reach 1.44 cm.

First, we convert 1.44 cm to mm, which is 1.44 cm × 10 mm/cm = 14.4 mm.

Next, we divide the total thickness (14.4 mm) by the thickness of each metal sheet (1.2 mm):

Number of sheets = 14.4 mm / 1.2 mm

= 12

Therefore, to achieve a thickness of 1.44 cm, you need to stack 12 metal sheets on top of each other.

#SPJ3

First convert 1.2mm to cm

10mm = 1cm

so 1.2mm = 0.12cm

Then divide 1.44cm by 0.12cm
that equals to 12.

so you need 12 sheets to make it 1.44cm
