Sometimes
for example a 30 degree angle has a 60 degree angle as its complement and a 150 degree angle as its supplement.

if you choose a 90 degree angle it can only have a supplement
if you choose a 180 degree angle it can't have either

a vehicle uses 1 1/8 gallons of gas to travel 13 1/2 miles. at this rate how many miles can the vehicle travel per gallon of gas

elena55 [62]

Answer:

The vehicle can travel 12 miles per gallon of gas.

Step-by-step explanation:

The number of gallons used by a vehicle = 1 1/8 gallons

i.e.

$1\frac{1}{8}=\frac{9}{8}$ gallons

The number of miles traveled by a vehicle = 13 1/2 miles

i.e.

$13\frac{1}{2}=\frac{27}{2}$ miles

Thus,

Total Gallons =9/8 gallons

Total Distance in miles = 27/2 miles

Hence:

Unit Rate = [27/2 miles] / [9/8 gallons]

= 12 miles per gallons ∵ $\frac{27}{2}\div \frac{9}{8}=12$

Therefore, the vehicle can travel 12 miles per gallon of gas.
