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

$\$60\ per\ hour$

How do I find miles per hour from 2 fractions? For Example: If I ran for 1/2 miles when It lasted 1/3 of an hour. Would It be 1/

ale4655 [162]

Answer:

3/2 miles per hour

Step-by-step explanation:

How do I find miles per hour from 2 fractions? For Example: If I ran for 1/2 miles when It lasted 1/3 of an hour. Would It be 1/6?

Given data

distance= 1/2 miles

time= 1/3 hour

Speed= distance/time

Substitute

Speed= 1/2/1/3

Speed= 1/2*3/1

Speed= 3/2 miles per hour

The function g(t) = - 16t2 + vt + h represents the height of an object, g, in feet, above the ground in relation to the time, t,

timurjin [86]

Answer:

$g(t) = -16t^2+80t$ .

Step-by-step explanation:

We are given that $v=80$ and $h=0$ (because that's the ground), so substituting that into $g(t) = -16t^2+vt+h$ gives $g(t) = -16t^2+80t$ .
