Rates are used to measure a quantity over another.
<em>The 1.8 million cars use </em>
<em> liters each year</em>
Given

--- distance

First, we calculate the number (n) of gallons used by each car

Solve for n

So, we have:


Convert miles to kilometers



The number of gallons (N), used by all the cars is:


Convert to liters


In scientific notation to 2 decimal places, we have:

<em>Hence, the number of liters used is </em>

120/210 = 0.57
0.57 x 60 = 34.2
34 hours and 12 minutes
C because there are 60 seconds in a minute so if you multiply 600 x 60 you get 36000
Answer:
answer is choice 4 because in te given angle A and angle B are congrunt and if they are acute the degree measure is 0-90
Answer: Total cost is $1.75
Explanation:
Since we have given that
Number of postcards bought by Doug's family= 7
Cost of each postcard including tax = $0.25
Total cost is given by

Now, we want to show this in number line :
On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.
Each step is of length 0.25 and there are 7 jumps to reach required answer.
So, after 7 jumps we reach at 1.75 which is the required answer.
Hence total cost is $1.75
