Answer:
1. The graph represents a proportional relationship
2. 70,000 miles
Step-by-step explanation:
1. The graph represents a proportional relationship since the graph line is straight and begins at the origin.
2. Plot 5.5 hours on the graph and it'll give you 70,000 miles
24:15 would be the simplified version, if that's what you meant.
Answer:
B
Step-by-step explanation:

Multiplication and division with the powers of ten
So, when multiply powers of ten, all you have to do add up the powers.
The reverse goes when you are dividing. You would subtract the powers.
9 x 10^7 => 3 x 10^3
The words " how many times as large as " indicates that we are going to divide the two, making it look like this:

Divide the 9 by 3 you get 3
Then subtract 10^3 from 10^7
Therefore, the answer is 3 x 10^4, or A
Answer:
18, 54, 108
Step-by-step explanation:
Let the first angle is ‘x’
Second angle =3x
Third angle=2(3x)=6x
Sum of the three angles of a triangle =180 degrees
x+3x+6x=180
x=18
The first angle is 18,second angle is (3*18)=54.third angle is (6*18)=108
The angles are 18,54 and 108 degrees
