1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700.
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.
I think the first box on the top is 10 and the bottom is 4. Hope this helped :)
Slope: Take two points from the graph, and do y-y, over x-x.
for ex. (1,2) and (2,4) do 4-2 over 2-1. your slope is 2/1= 2
y-intercept: find the one point on the graph that is exactly on the y-axis.
for ex. (4,0)= your y-intercept is 4
The number of stamps and the cost are illustrations of unit rates
40 stamps would cost $22
The cost of 15 postage stamps is $8.25
Start by calculating the unit rate of the stamps.


So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.
So, we have:


Hence, 40 stamps would cost $22
