A cougar is sleeping for 4 hours at night, and a zebra for 2 hours more. How much time do both animals sleep in one week?
Let's think: The zebra sleeps for 4 + 2 = 6 hours. During one week, the cougar sleeps 4 * 7 = 28 hours. And the zebra sleeps 6 * 7 = 42 hours. Both animals sleep for 28 + 42 = 70 hours during one week.. The answer is: 70.

Adah practiced the cello for a total of 7.5 hours last week. He practiced for 86 minutes on each of 2 days. How many minutes in total did he practice on the other days?
Let's think: 7.5 hours = 450 minutes. Two days = 2 * 86 = 172 minutes. 450 - 172 = 278 minutes. Adah practiced a total of 278 minutes on the other days.. The answer is: 278.

Kat gets a 95% on her first math test and an 80% on her second math test. If she wants an average grade of at least 90% in her math class, what does she need to get on her third final math test?
Let's think: Let x = the percent needed on her third math test. (95 + 80 + x) / 3 = 90. (95 + 80 + x) = 270. x = 270 - 95 - 80. x = 95.. The answer is: 95.

Frank originally had 5 + 8 = 13 apples. After his dog eats 3, there are 13 - 3 = 10 apples.. The answer is: 10.
