Answer: not proportional


Step-by-step explanation:

The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.

In the given table , let the variables are proportional then the constant of proportion(k)=(y)/(x)

\Rightarrow\ k=(3)/(2)=1.5

\Rightarrow\ k=(7)/(4)=1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.
The answer is:Not proportional

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.

keith spent 60% of jis birthday money at the mall. If he spent $24 at the mall, how much money did Keith receive for his birthday

Answers

24 x 100 = 2400

2400 divided by 60 = 40

Keith got $40 for his birthday.
We know that Keith spend 60% of his money, or $24
60% = $24
To find 100%, we must first find 10%
To get from 60% to 10%, we divide by 6
Do the same to the other value
$24 / 6 = $4
10% = $4
To find 100%, we now multiply by 10
$4 x 10 = $40
Keith received $40 for his birthday

Help pls 2,4 +0,8=........+1,21=........+1,78=........-5,14=

Answers

Lets write this out:-

2.4 + 0.8 = ________ + 1.21 = ______ + 1.78 = ______ - 5.14 = _____

So to solve d blanks we will do d following:-

2.4 + 0.8 = 3.2

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = ______ + 1.78 = ______ - 5.14 = ____

Now lets solve again:-

3.2 + 1.21 = 4.41 

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = ______ - 5.14 = ____

Now lets solve again:-

4.41 + 1.78 = 6.19

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = 6.19 - 5.14 = ____

Now lets solve again:-

6.19 - 5.14 = 1.05

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = 6.19 - 5.14 = 1.05

So, 2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = 6.19 - 5.14 = 1.05
