Question

Annapolis, Maryland has an approximate population of 36,000. Columbus, Ohio has an approximate population of 7.3 x 105. Which of the following is true?
Question 2 options:


Annapolis is approximately twice the size of Columbus.


Columbus is approximately 200 times larger than Annapolis.


Columbus is approximately 20 times larger than Annapolis.


Annapolis is approximately 5 times larger than Columbus.

Answer 1

Given, Annapolis, Maryland has an approximate population of 36,000.

And Columbus, Ohio has an approximate population of $(7.3)(10)^5$.

First we have to multiply $(7.3)(10)^5$.

$(7.3)(10^5) = (7.3)(100000) = 730000$

We can see the population of columbus is larger than population of Annapolis.

Now we will divide the population of Columbus by the population of Annapolis to find how much times the population of columbus is larger. We will get,

$\frac{730000}{36000}$ = 20.28 ( Approximately taken upto two decimal place)

So it is more than 20 times.

We can say, The population of columbus is approximately 20 times larger than Annapolis.

We have got the required answer.

Option 3 is correct.
