Answer:
She work <u>23 hours</u>.
Step-by-step explanation:
Given:
Tracy works at the Pizza Place. She earns $4.50 an hour plus tips.
Last week, she earned a total of $156.00, of which $52.50 was tips.
Now, to find the number of hours she work.
Total salary = $156.00
Amount of tips = $52.50.
So, first we deduct the amount of tips from the total salary:

<em>Thus, the remaining salary = $103.50.</em>
As, given salary she earns an hour = $4.50.
And then, to get the number of hours she work last week by dividing $103.50 the remaining salary by $4.50:


Therefore, she work 23 hours.

Step-by-step explanation:
Answer:
Input
Independent variable
Step-by-step explanation:
we know that
<u>Independent variables</u>, are the values that can be changed or controlled in a given model or equation
<u>Dependent variables</u>, are the values that result from the independent variables
we have the function

In this problem
This is a proportional relationship between the variables d and t
The function d(t) represent the dependent variable or the output
The variable t represent the independent variable or input
Answer: 102
-----------------------------------------------
We'll use the formula
A = h*(b1+b2)/2
where
A = area of trapezoid
h = height
b1 & b2 are the parallel bases
In this case,
b1 = 6+7 = 13
b2 = 21
h = 6
Making the area to be
A = h*(b1+b2)/2
A = 6*(13+21)/2
A = 6*(34)/2
A = 204/2
A = 102
Side Note: We don't use the slanted side of 10 cm at all
