An office building casts a shadow that is 55 m long. at the exact same time, a 5 m tree casts a shadow that is 1.1 m long. use similar triangle ratios, to calculate the height of the office building.

The ratio of the triangle is 55/1.1, which is 50/1.

This means that the building is 50/1 = x/5

x = 250

The office building is 250 m tall.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
