Question

13. Summerville has a population of 430,000

people, while Eagleton has a population of
5.7 x 105 people. What is the difference in
population between the two towns? Write your
answer in scientific notation.

Answer 1

The difference in population between Summerville and Eagleton is 140,000 people, which is written as 1.4 x 10^5 in scientific notation.

Step-by-step explanation:

To determine the difference in population between Summerville and Eagleton, we need to subtract the population of Summerville from the population of Eagleton. Eagleton's population is given in scientific notation as 5.7 x 105, which equals 570,000 people. Summerville has a population of 430,000 people. Performing the subtraction, we get:

570,000 (Eagleton) - 430,000 (Summerville) = 140,000

To express 140,000 in scientific notation, we write it as 1.4 times 105. Therefore, the difference in population between the two towns is 1.4 x 105, expressed in scientific notation.

Answer 2

1.4 x 10 to the power of 5

Step-by-step explanation:

5.7 x 10 to the power of 5 = 570,000

570,000 - 430,000 = 140,000

1.4 x 10 to the power of 5 = 140,000

1.4 x 10 to the power of 5 is the answer
