Question

Frank created a circle graph to show how he spent his time one day. He spent 8 hours at school, 8 hours sleeping, and the rest of the time hanging out at home. What percentages will be included in his circle graph?

Answer 1

Answer:

The three percentages are the same and equal to $33.33\%$

Step-by-step explanation:

Let

x------> is the time hanging out at home

y------> is the time he spends sleeping

z------> is the time he spends in school.

we know that

One day has $24$ hours

so

$x+y+z=24$

$y=8\ hours$

$z=8\ hours$

Substitute the values and solve for x

$x+8+8=24$

$x=24-16=8\ hours$

Find the percentages

$x=\frac{8}{24}*100=33.33\%$

$y=\frac{8}{24}*100=33.33\%$

$z=\frac{8}{24}*100=33.33\%$

The three percentages are the same and equal to $33.33\%$

Answer 2

If there are 24 hours a day, he hangs out 8 hours a day since 24-8-8=16

All activities are eqyal to 8/24, which simplifies to 1/3.

1/3 as a percent is 33.33...%

He should include 33.33..% three times in his circle graph.
