What is the similarity ratio of the smaller to the larger similar cones? enter your answer as a: b

To find similarity ratio a:b

We take the sides and make a proportion

So the ratio a:b is 3:5

at 0 hours the plane has 422,000 gallons of gas.

after 2 hours it has 369,250 gallons.

subtract to find the difference and then divide by 2 hours:

422000 – 369250 = 52750 /2 = 26,375 gallons per hour.

can also do the full 16 hours:

the plance used 422,000 gallons in 16 hours:

422,000 / 16 = 26,375 gallons per hour.
