Roberto is having his house painted. The job takes three days, and he pays the painter the same hourly rate
Tom [10]

Answer:

\$60\ per\ hour

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of hours worked

y ----> the amount paid in dollars

In this problem we have a proportional variation, between two variables, x, and y

<em>Find out the constant of proportionality k</em>

For (5,300) -----> k=y/x ----> k=300/5=60\ \$/h

For (4,240) -----> k=y/x ----> k=240/4=60\ \$/h

For (6,360) -----> k=y/x ----> k=360/6=60\ \$/h

The constant k is

k=60\ \$/h

The equation is equal to

y=60x

The unit rate of change of dollars with respect to time is equal to the constant of proportionality or slope of the linear equation

therefore

\$60\ per\ hour

The ratio of youths to adults at a skating rink is 13:7. What percent of these people are youths?
lara31 [8.8K]
The percentage of people at the scathing ring that are Youth is 65%. You would have to add 13 + 7, to get 20. Then you do 100 percent divided by 20 to get 5. Finally, you would do 5 times 13 to reach 65%.
