Answer:
360
Step-by-step explanation:
A circle has 360 degrees.
Here lesson started at 9 and finished at 10.
This means that her lesson was one hour.
A minute hand makes a full rotation in an hour.
It would have started at 12, and ended back at 12.
This means that it rotated 360 degrees.
Answer:

Step-by-step explanation:
In this exercise, we have two equations, namely:

And we are asked to solve this problem by graphing. In this way, we can write a system of linear equations in two variables, but first of all, let's rewrite:

Then:

So here we have two lines.
The first one is:

This line passes through the origin and has a slope 
The second one is:

This line has a slope
and cuts the y-axis at 
By using graph tools, we get the graph shown below, then:

Answer:
48
Step-by-step explanation:
You are doubling 2 dimensions, so you just multiply the volume by 2 each time. Since you are doing it twice, you multiply the volume by 4. 12*4=48. You could also brute force it and just do 24*36*12/216(the volume of the 6 inch cube).
You can use the distibutive property by breaking apart the bigger number (38) into 30 and 8. Now, you can do: (9 x 30) + (9 x 8)
I hope this helps!!!
