A tiger sleeps 18 to 20 hours a day. How many hours will a tiger sleep in 7 weeks?
A. 2.5 to 2.9 hours
B. 882 to 980 hours
C. 630 to 700 hours
D. 126 to 140 hours
To find the number of hours a tiger will sleep in 7 weeks, we can multiply the number of hours a tiger sleeps per day by the number of days in 7 weeks (49 days). The tiger will sleep for 18 to 20 hours per day.
So, the tiger will sleep for 18 x 49 to 20 x 49 hours in 7 weeks.
This equals 882 to 980 hours.
Therefore, the correct answer is option B. 882 to 980 hours.
To find out how many hours a tiger will sleep in 7 weeks, first, we need to calculate the total number of hours in 7 weeks.
One week has 7 days, and there are 7 weeks in total, so the total number of days is 7 x 7 = 49 days.
Since a tiger sleeps 18 to 20 hours a day, we can calculate the minimum and maximum number of hours a tiger will sleep in 49 days.
The minimum number of hours is 18 x 49 = 882 hours.
The maximum number of hours is 20 x 49 = 980 hours.
Therefore, the tiger will sleep for 882 to 980 hours in 7 weeks.
Hence, the correct answer is option B. 882 to 980 hours.
To find the number of hours a tiger will sleep in 7 weeks, we can start by calculating the number of hours a tiger sleeps in a day: 20 hours - 18 hours = 2 hours.
Next, we need to determine how many days are in 7 weeks. Since there are 7 days in a week, we can multiply 7 by the number of weeks: 7 weeks * 7 days/week = 49 days.
Finally, we can multiply the number of hours a tiger sleeps in a day by the number of days in 7 weeks: 2 hours/day * 49 days = 98 hours.
Therefore, a tiger will sleep for 98 hours in 7 weeks.
The correct answer is D. 126 to 140 hours.
