Answer:
7 cents/mile
Step-by-step explanation:
You are looking for a unit rate of cents per mile.
Change the dollar amount to cents, and divide by the number of miles.
$13.08 * (100 cents)/$ = 1308 cents
(1308 cents)/(183 miles) = 7.001 cents/mile

Answer:
76
Step-by-step explanation:
arrange the data set from least to greatest:
16, 31, 55, 61, 92
Range = Highest value - Lowest value = answer
Range = 92 - 16 = 76
You are right to circle both 10 or 12. Neither can be solved without knowing something about the x values in 10 and the x value of the smaller base in 12.
In this problem, you are asked to write a number in
scientific notation. In figures, 78 million would look like this:
78,000,000
To write this to scientific notation, you have to move the
decimal point to the left until you will get a number between 1 and 10.
Here, you will have to move the decimal point 7 times to get
7.8
The exponent of the scientific notation is the number of
times you moved your decimal point. Since the movement of decimal point is
going to the left, you will have a positive exponent.
The scientific notation would look like this:
7.8 x 10^7
