Answer:
$138
Step-by-step explanation:
We can first turn the words into a mathematical equation by substituting words with the information we have:
Total earning - ( Price of three books)
$180 - (Price of one book x 3)
$180 - ($14 x 3)
Finally, after we have created the mathematical equation, we solve it!
$180 - ($14 x 3)
$180 - $42
$138
I would need to know the denominators that are showed to be able to answer the question
Answer:
![V_2 = 583.67](https://tex.z-dn.net/?f=V_2%20%3D%20583.67)
Step-by-step explanation:
Given
Represent the volume of the cylinder with V1 and the cone with V2.
So:
![V_1 = 1751](https://tex.z-dn.net/?f=V_1%20%3D%201751)
Required
Find V2
The volume of a cylinder is:
![V_1 = \pi r^2h](https://tex.z-dn.net/?f=V_1%20%3D%20%5Cpi%20r%5E2h)
Because the cone and the cylinder have the same base area and height, the volume of the cone is:
![V_2 = \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
Substitute
for
.
![V_2 = \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
![V_2 = \frac{1}{3}V_1](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B1%7D%7B3%7DV_1)
Substitute 1751 for V1
![V_2 = \frac{1}{3} * 1751](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%201751)
![V_2 = \frac{1* 1751}{3}](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B1%2A%201751%7D%7B3%7D)
![V_2 = \frac{1751}{3}](https://tex.z-dn.net/?f=V_2%20%3D%20%5Cfrac%7B1751%7D%7B3%7D)
![V_2 = 583.67](https://tex.z-dn.net/?f=V_2%20%3D%20583.67)
<em>The volume of the cone is 583.67 cubic units</em>
Answer:
8
Step-by-step explanation:
There are 4 possible ways he could have written it: chalk, pen, pencil, and marker.
There are 2 ways he wrote it: French and English
4*2=8
He wrote his name in 8 different ways.
The answer is $79.96 but rounded it would be $80
