Answer:
The car uses less gas
They use the same amount of gas after 
miles
Step-by-step explanation:
Given
The table represents the car mileage
--- The van
First, calculate the car's slope (m)
From the table, we have:
So, we have:
Calculate the equation using:
implies that for every mile traveled, the car uses 1/40 gallon of gas
Also:
--- The van
By comparison to: 
This implies that for every mile traveled, the van uses 1/5 gallon of gas.
By comparison:
This means that the car uses less gas
Solving (b): Distance traveled for them to use the same amount of gas.
We have:
--- The van
--- The car

Answer:
First one: 0.4
Second one: 4
Step-by-step explanation:
We find the cube root of 0.064 which is 0.4
In order to find the length of side s, we just cube root 64 because it is 
Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.
