Tigger sleeps 18 to 20 hours a day how many hours will Tiger sleep in seven weeks?
A. 630 to 700 hours.
B. 882 to 980 hours
C. 2.5 to 2.9 hours.
D. 126 to 140 hours.
To calculate the number of hours Tiger will sleep in seven weeks, we need to multiply the sleep duration per day by the number of days in seven weeks. The number of days in seven weeks is 7 x 7 = 49 days.
The range of sleep duration per day is 18 to 20 hours. Multiply the lower range by 49 days to get the minimum hours slept: 18 x 49 = 882 hours.
Multiply the upper range by 49 days to get the maximum hours slept: 20 x 49 = 980 hours.
Therefore, the answer is B. 882 to 980 hours.
To calculate the number of hours Tiger will sleep in seven weeks, we need to know the average number of hours he sleeps per day.
Average number of hours Tigger sleeps per day: (18 hours + 20 hours) / 2 = 19 hours
Now, let's calculate the number of hours Tiger will sleep in seven weeks:
Total number of days in seven weeks: 7 weeks * 7 days/week = 49 days
Total number of hours Tiger will sleep in seven weeks: 19 hours/day * 49 days = 931 hours
Therefore, the answer is not given in the options provided. The correct answer should be 931 hours.
To find out how many hours Tigger will sleep in seven weeks, we need to first determine the range of hours Tigger sleeps per day (18 to 20 hours), and then multiply it by the number of days in seven weeks.
The range of hours Tigger sleeps per day is 18 to 20 hours. We can calculate the minimum hours Tigger sleeps in one day by taking the lower limit of the range (18 hours). Similarly, the maximum hours Tigger sleeps in one day can be calculated by taking the upper limit of the range (20 hours).
Next, we need to determine the number of days in seven weeks. Since there are 7 days in a week, we can multiply 7 by 7 to find the total number of days in seven weeks, which is 49 days.
Now, we can calculate the minimum and maximum number of hours Tigger will sleep in seven weeks by multiplying the range of hours per day by the number of days in seven weeks.
Minimum hours slept in seven weeks = minimum hours per day * number of days in seven weeks
= 18 hours * 49 days
= 882 hours.
Maximum hours slept in seven weeks = maximum hours per day * number of days in seven weeks
= 20 hours * 49 days
= 980 hours.
Therefore, Tigger will sleep between 882 to 980 hours in seven weeks.
So the correct answer is B. 882 to 980 hours.
