Answer:
$12,000,000
Step-by-step explanation:
To find her commission, create a proportion.

To solve use cross multiplication.
40(x) = 100(480000)
40x = 48000000
x= 12,000,000
Answer:
The average temperature of coffee in the sample, which is 70.2.
Step-by-step explanation:
The population is all the costumers. The company has determined that they want the average coffee temperature to be 65 degrees C. So, 65 degrees C is the average of the population.
The sample is the 20 orders. The mean
of the sample is 70.2C(That is, the mean of the 20 orders0. So, the correct answer is:
The average temperature of coffee in the sample, which is 70.2.

SAS stands for side angle side. so in this question we know that one side is equal to another side, but we don't know wether or not there is another angle and another side that is congruent. so for that reason it is not congruent by SAS.
Answer:
Width=20 feet
Since Length=Width=20 feet, the rectangle is a Square.
Step-by-step explanation:
Area, 
To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.

The width of the rectangle that gives the maximum area =20 feet.
Perimeter of a rectangle=2(l+w)
Perimeter of the rectangle=80 feet
2(l+w)=80
2l+2(20)=80
2l=80-40
2l=40
l=20 feet
Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
Answer:
the price per book is $3 the constant of proportionality is 3
Step-by-step explanation:
12 divided by 4 is 3 and 9 divided by 3 is 3 so it means that the price for 1 book is going to be 3 and for every book you buy the original value will be 3.
