A tiger sleeps 18 to 20 hours a day. How many hours will a tiger sleep in 7 weeks? (1 point)
O 126 to 140 hours
25 to 2.9 hours
630 to 700 hours
882 to 980 hours
To find out how many hours a tiger will sleep in 7 weeks, we can multiply the number of hours it sleeps per day by the number of days in 7 weeks.
If a tiger sleeps for 18 to 20 hours a day:
Minimum hours slept in 7 weeks = 18 hours/day * 7 days/week * 7 weeks = 882 hours
Maximum hours slept in 7 weeks = 20 hours/day * 7 days/week * 7 weeks = 980 hours
Therefore, a tiger will sleep 882 to 980 hours in 7 weeks.
To calculate the number of hours a tiger will sleep in 7 weeks, we need to multiply the number of hours a tiger sleeps per day by the number of days in 7 weeks.
First, let's calculate the number of days in 7 weeks:
1 week = 7 days
7 weeks = 7 * 7 = 49 days
Since a tiger sleeps 18 to 20 hours a day, we'll calculate the range:
18 hours x 49 days = 882 hours
20 hours x 49 days = 980 hours
Therefore, a tiger will sleep for 882 to 980 hours in 7 weeks. The answer is option "882 to 980 hours".
To find the number of hours a tiger will sleep in 7 weeks, we first need to find the total number of hours a tiger sleeps in one day. It is given that a tiger sleeps 18 to 20 hours a day.
To find the minimum number of hours a tiger sleeps in one day, we take the lower bound of 18 hours.
To find the maximum number of hours a tiger sleeps in one day, we take the upper bound of 20 hours.
Now, we can calculate the minimum and maximum number of hours a tiger will sleep in 7 weeks.
Minimum hours = 18 hours per day * 7 days in a week = 126 hours
Maximum hours = 20 hours per day * 7 days in a week = 140 hours
Therefore, a tiger will sleep between 126 to 140 hours in 7 weeks.
So, the correct answer is option O: 126 to 140 hours.
