Answer:
This question is incomplete
Step-by-step explanation:
This question is incomplete. However, there are mainly four types of graphical representations in mathematics; line graph, bar graph (and histogram), pie chart and cartesian graph. The most suitable representation for fluctuating data sets of the same variables on each of the y and x-axis is the line graph. Since download speed will fluctuate during the course of a download, the correct type of graph to be used here will be the line graph. And the exact type of line graph that will be used here is a simple line graph. A simple line graph is a type of line graph in which one line is drawn on the graph. A simple line graph is usually used to represent two variables (in this case data downloaded per time).
The volume of a cylinder with a radius r and a height h:

The volume of a cone with a radius r and a height h:

Therefore

We have 
Substitute:

Answer: The volume of a cone is equal 10.75 in³
Answer:
12x+19.95=13x+9.95
19.95=x+9.95
10=x
So after 10 classes the cost will be the same
12(10)+19.95=120+19.95= $139.95
13(10)=9.95=130+9.95= $139.95
Answer:
x=m/(p+r)
Step-by-step explanation:
m/x-r=p
m/x=p+r
m=x(p+r)
m/(p+r)=x
