Answer: 1/10
Step-by-step explanation:
From the question, we are informed that Karen spent 7/10 hour reading and 3/5 hours writing in her journal.
To calculate how much longer karen spent reading than writing in her journal, we have to subtract 3/5 from 7/10. This will be:
= 7/10 - 3/5
Note that the lowest common multiple of 5 and 10 is 10.
= 7/10 - 6/10
= 1/10
Therefore, the answer is 1/10

Answer:
so whats the question
Step-by-step explanation:
Question:
Suppose that the populations of the United States and China both increase by 12 million people in one year. What would be the relative change for each country? Answer to the nearest tenth of a percent (1 decimal place). Make sure that you fill in each answer area before checking "How Did I Do?".
If you assume that the U.S. population is about 300 million, an increase of 12 million would result in a relative change of Number %.
If you assume that China has about 1 billion people, an increase of 12 million would result in a relative change of Number %.
Answer:
The relative change of the United States and China is 4% and 1.2%, respectively.
Step-by-step explanation:
Given
Represent population with p. So, we have:
United States


China


Required
Determine the relative change for each country
Relative change, C is calculated as:

For United States





For China





The relative change of the United States and China is 4% and 1.2%, respectively.
The area is 40 because you do 12 times two then eight times two then add the awnsers
