Rooter Plus charges a $25 service fee plus $40 per hour of work done. Is this a proportional or non-proportional relationship?
1 answer:
Answer:
Non-proportional; the rate of change is $40/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 or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and the line passes through the origin</u>
Let
x -----> the number of hours
y ----> The total charge in dollars
The equation of the line in slope intercept form is equal to
where
m is the slope
b is the y-intercept
we have
substitute
This relationship is not proportional, because the line not passes through the origin
therefore
Non-proportional; the rate of change is $40/hour

Answer:
<u>44 fluid ounces</u> of lemonade are left.
Step-by-step explanation:
Given:
Tate fills a container with 9 1/2 cups of lemonade.
Tate drinks 32 fl. oz. of lemonade.
Now, to find the quantity of fluid ounces left.
So, we convert the unit of cups into fluid ounces.
Tate fill the container of lemonade with =
As, 1 cup = 8 fluid ounces.
So, by conversion factor:
<em>Thus, Tate fill the container of lemonade with = 76 fl. oz.</em>
<em>Tate drinks lemonade = 32 fl. oz.</em>
Now, to get the fluid ounces left we subtract the quantity of lemonade Tate drink from the total quantity of lemonade filled in the container:
Therefore, 44 fluid ounces of lemonade are left.
