Question

use the drop - down menus to complete each sentence. experts recommend that teens get between 7 to 8 hours of sleep each night. angelique needs to get up at 7 a.m. to get ready for school the next day, so she should plan on going to sleep around 8 p.m. 10 p.m. 12 a.m.

Explanation:

Step1: Calculate sleep duration from 10 p.m. to 7 a.m.

From 10 p.m. to 12 a.m. is \(12 - 10= 2\) hours. From 12 a.m. to 7 a.m. is \(7-0 = 7\) hours. Total sleep time is \(2 + 7=9\) hours.

Step2: Calculate sleep duration from 8 p.m. to 7 a.m.

From 8 p.m. to 12 a.m. is \(12 - 8 = 4\) hours. From 12 a.m. to 7 a.m. is \(7-0=7\) hours. Total sleep time is \(4 + 7 = 11\) hours.

Step3: Calculate sleep duration from 12 a.m. to 7 a.m.

From 12 a.m. to 7 a.m. is \(7-0 = 7\) hours. But \(7\) hours is at the lower - end of the \(7 - 8\) hour recommendation. \(10\) p.m. gives a more reasonable \(9\) hours (close to the recommended range).

Answer:

10 p.m.
