Use the circle graph to determine how many hours per day Becky spends on each activity.
Oduvanchick [21]
404 error: graph not found

anyway, the graph was not included. since the sleep time was included, I will assume that the circle graph is worth 24 hours

all we need to do is to convert the percentages to fractions and multiply that by 24 to find out how many hours per activity


percent means parts out of 100 so x%=x/100


so we have
School
Eating
Sleep
Homework
Free Time

School=25%
25%=25/100=1/4
1/4 times 24=6
School: 6 hours


Eating=10%
10%=10/100=1/10
1/10 times 24=2.4
Eating: 2.4 hours


Sleep=40%
40%=40/100=4/10=2/5
2/5 times 24=48/5=9.6
Sleep: 9.6 hours


Homework=10%
10%=10/100=1/10
1/10 times 24=2.4
Homework: 2.4 hours


Free Time=15%
15%=15/100=3/30
3/20 times 24=72/20=36/10=3.6
Free Time: 3.6 Hours

Answers:
School: 6 hours
Eating: 2.4 hours
Sleep: 9.6 hours
Homework: 2.4 hours
Free Time: 3.6 Hours

Choose which set or sets the following number belongs to. Be sure to account for ALL sets.
Lelechka [254]

The sets to which the number -√3 belongs are:

D: Rational numbers.

E: Real numbers.

<h3>To which sets the number belong?</h3>

Here we have the number:

-√3

Notice that 3 is a prime number, and the square root of 3 is then an irrational number.

If it is an irrational number, it also is a real number (Remember that the real set contains all the numbers that are either rational or irrational). And because it has a negative sign, it is a negative number.

Then the correct options are:

D: Rational numbers.

E: Real numbers.

Concluding, the sets to which the number -√3 belongs are:

D: Rational numbers.

E: Real numbers.
