2:4
4:8
5:10
200:400
This is because if you divide each ratio you get 1/2
Volume = pi x radius^2 x height
400=3.14 x 4^2xheight
400=50.24h
400/50.24= h
7.96 = height
Answer:
11/17≈0.647059
Step-by-step explanation:
Ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375
hence ,<span> there is a greater proportion of smokers in the second city than in the first.
