The calculation is not reasonable, because 0.45 is less tha 1/2 ( 0.50) and what he has for an answer is half the distance ( 250.17 is 1/2 of 500.34).
To find actual mileage, multiply by 0.45:
500.34 x 0.45 = 225.153 miles.
Round the answer as needed.

Answer:
Step-by-step explanation:
In order to add or subtract numbers in scientific notation, the powers of ten must have the same exponent. In this caes the diameter of an average human body cell is a power of -4 and the diameter of a plant cell is a power of -3. In order to add them, we can move the decimal over for the body cell diameter:
Add the two values: 
Answer:
I would say B
Step-by-step explanation:
A. would make no sense and the graph will always have a straight line unless its compairing something and it does not have anything to do with 0 because it shows where it starts
The height of Mount Kilimanjaro is 19,340 feet.
To convert to scientific notation move the decimal point so there is only 1 digit to the left of the decimal pint, you then multiply that by 10 raised to the number of spaces you moved the decimal point.
19,340 - Move the decimal point 4 places to the left to get 1.9340
You can remove the 0 at the end to get 1.934
You moved the decimal 4 places so raise 10 to 4 and get the final answer:
1.934 x 10^4
The first choice is the correct one.
