Grade 7 students were surveyed to determine how many hours a day they spent, on average, doing various activities. The results are shown in the circle graph. About how much time do seventh-graders spend at school and eating combined? Round answers to the nearest tenth, if necessary.

To combine, add the values.

To find the amount of time seventh-graders spend at school and eating combined, we need to add up the percentages for those two categories on the circle graph.

First, let's find the percentage for the "School" category.

Looking at the circle graph, find the section that represents "School." Look at the corresponding number or label next to that section, which indicates the percentage for that category. Let's say it is 20%.

Next, let's find the percentage for the "Eating" category.

Again, look at the circle graph and find the section that represents "Eating." Look at the corresponding number or label next to that section, which indicates the percentage for that category. Let's say it is 15%.

Now, add up the percentages for school and eating: 20% (school) + 15% (eating) = 35%.

The sum of the percentages is 35%.

Finally, to convert the percentage to hours, multiply the total number of hours in a day (24 hours) by the percentage:

35% of 24 hours = 0.35 * 24 hours = 8.4 hours.

So, about 8.4 hours is the approximate amount of time seventh-graders spend at school and eating combined. Rounded to the nearest tenth, this would be 8.4 hours, or approximately 8.4 h.

Therefore, the correct answer is approximately 8.4 h.
