he circle graph shows how Tremaine divided his time on the computer last week.
Tremaine used the computer a total of 30 hours last week. How many more hours did Tremaine use the computer to play games than to do research?
6 hours
20 hours
7.5 hours
1.5 hours
To find out how many more hours Tremaine used the computer to play games than to do research, we first need to calculate the number of hours he spent on each activity based on the circle graph.
From the circle graph:
- Games: 40%
- Research: 20%
- Other: 40%
Calculating the hours spent on each activity:
- Games: 40% of 30 hours = 0.4 * 30 = 12 hours
- Research: 20% of 30 hours = 0.2 * 30 = 6 hours
Now we can calculate the difference in hours:
12 hours (games) - 6 hours (research) = 6 hours
Therefore, Tremaine used the computer 6 hours more to play games than to do research. So the answer is 6 hours.
