Answer:
For B the answer is 1 : 30. For A the graph is Y goes up 2 for every 60 on the X.
Answer:
The scale factor is 
Step-by-step explanation:
Yes the figures are similar to each other. The ratio of their linear measurements is in uniform ration
The ration of radius of large cylinder (R) to that of the smaller cylinder (r) is

Like wise the ration of height of large cylinder (H) to that of the smaller cylinder (h) is

The scale factor is 
28/100=14/50=7/25 &the second one 2=200/100 so 200/100+65/100=265/100
265/100=53/20
0, 12, 36, 108
just plug n (1,2,3,4) into the equation and that’s your answer.
1/2d+6=1/2(d+12)
Leaving us with 0.5 or 1/2
