Answer:

Step-by-step explanation:

Answer: 348.8 miles on 16 gallons of gas
Step-by-step explanation:
Make the following proportion:
= 
Since the car consumes gas at the same rate and only the amount of gas is changed, these two fractions must be equivalent. If the rate at which the car consumes gas changes, it would be different.
Use basic algebraic skills and you should get 348.8 miles.
D(x)=1375-110x
when it reaches 0 it has reached destination
0=1375-110x
add 110x to both sides
110x=1375
divide both sides by 110
x=12.5
answer is 12.5 hour
The obtuse angles are all the same, and in order to find the acute angles you have to subtract the obtuse angle from 180 degrees.
Acute angles will be equal to 180-130 = 50 degrees.
All the obtuse angles will be the same and all the acute angles will be the same.
