Ababy goes to sleep at 8 p. m., wakes up after two hours, stays awake for 15 minutes, and then goes back to sleep. if the baby repeats this sleep pattern until she is awakened at 6 a. m., what percent of the time from 8 p. m. to 6 a. m. was the baby asleep?

87.5%

Step-by-step explanation:

I am not sure how to set this upso I am just gonna try to figure this a different waywithout any formula

8 p.m - 10 pmawake for 15 minutes

10 pm - 12 amawake 15 minutes

12 am - 2 amawake 15 minutes

2 am to 4 amawake 15 minutes

4 am to 6 amawake 15 minutes

so from 8 pm to 6 amthat is a total of 10 hrsand in those 10 hrs, the baby was awake 5(15) = 75 minuteschange 10 hrs to minutes1 hr = 60 min...so 10 hrs = (10 * 60) = 600 minutes

so in 600 minutes, the baby was awake 75 minutesthat means the baby was asleep (600 - 75) = 525 minutes

525/600 = 0.875 = 87.5% <=== baby was asleep

or maybe this wayfor every 2 hrs, the baby was awake 15 minutesmeans the baby was asleep (120 - 15) = 105 minutes.

2 / 105 = 10 / x

2x = 1050

x = 1050/2

x = 525 minutesso the baby was asleep 525 minutes out of 600 minutes.

525/600 = 0.875 = 87.5%

I am getting the same answer either way

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
