In 2012, the population of NY was about 2.4 x 10^7 and the population of Oregon was 4x10^5. What is the total population of the two states?

9 answers

To find the total population of the two states, we simply add the populations of NY and Oregon together.

Total population = population of NY + population of Oregon

Total population = 2.4 x 10^7 + 4 x 10^5

Total population = 24,000,000 + 400,000

Total population = 24,400,000

Therefore, the total population of NY and Oregon is 24.4 million.
3.71 x 10^5 + 4.65 x 10^5
To add 3.71 x 10^5 and 4.65 x 10^5 together, we first need to make sure the exponents are the same.

3.71 x 10^5 = 371,000
4.65 x 10^5 = 465,000

Now we can add them together:

371,000 + 465,000 = 836,000

Therefore, 3.71 x 10^5 + 4.65 x 10^5 is equal to 8.36 x 10^5.
7.35 x 10^-7 + 2.16 x 10^-8
To add 7.35 x 10^-7 and 2.16 x 10^-8 together, we first need to make sure the exponents are the same.

7.35 x 10^-7 = 0.000000735
2.16 x 10^-8 = 0.0000000216

Now we can add them together:

0.000000735 + 0.0000000216 = 0.0000007566

Therefore, 7.35 x 10^-7 + 2.16 x 10^-8 is equal to 7.566 x 10^-7.
5 x 10^3 + 3 x 10^5 =
To add 5 x 10^3 and 3 x 10^5 together, we first need to make sure the exponents are the same.

5 x 10^3 = 5,000
3 x 10^5 = 300,000

Now we can add them together:

5,000 + 300,000 = 305,000

Therefore, 5 x 10^3 + 3 x 10^5 is equal to 3.05 x 10^5.
In 2006, the US had a Gross Domestic
What do I need help with?
Product (GDP) of 1.313 x 10^13. The United Kingdom had a GDP of 1.93 x 10^12. What
were the combined GDPs of the US and the UK in 2006?

Incorrect Work/ Laila’s Solution Identify and Explain the error
(1.313 x 10^13) + (1.93 x 10^12)
1.313 + 1.93 = 3.243
10^13 + 10^12 = 10^25

The combined GDPs of the US and the UK in 2006 was
3.243 x 10^25.
Laila's solution to add the GDPs of the US and the UK is incorrect. She correctly added the values outside the exponents (1.313 + 1.93 = 3.243), but made an error when adding the exponents (10^13 + 10^12 = 10^25).

To add the GDPs correctly, we need to make sure the exponents are the same:

1.313 x 10^13 = 13,130,000,000,000
1.93 x 10^12 = 1,930,000,000,000

Now we can add them together:

13,130,000,000,000 + 1,930,000,000,000 = 15,060,000,000,000

Therefore, the combined GDPs of the US and the UK in 2006 was 1.506 x 10^13, not 3.243 x 10^25 as incorrectly calculated by Laila.
