Dennis takes care of private swimming pools. He charges $50 to travel to a home and then $30 per hour. The equation t=50+30h models the total charge t for h hours of service. Find the ordered pair that presents 3 hours of work

(3, 140)

Step-by-step explanation:

If we have the equation , we can substitute the value 3 as to find the value of .

So we know that the total cost is $140.

To represent this as an ordered pair, we need to take note that the independent variable (x) is the one that we change to get the result (y).

We changed to get , so is the x and is the y.

So it's represented as (3, 140).

Hope this helped!

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

this is answer of 144 cubic meters
