To determine how many hours a tiger will sleep in 7 weeks, we can multiply the number of hours it sleeps per day (18 to 20) by the number of days in a week (7).
Range:
Minimum hours: 18 * 7 = 126 hours
Maximum hours: 20 * 7 = 140 hours
Therefore, a tiger will sleep between 126 to 140 hours in 7 weeks.
Option 1: 126 to 140 hours
Option 2: 126 to 140 hours
Option 3: 882 to 980 hours
Option 4: 2.5 to 2.9 hours
Correct response: 126 to 140 hours
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.
Since the tiger sleeps for 18 to 20 hours a day, we will take the average of these two numbers, which is 19 hours.
Now, we need to determine the number of days in 7 weeks. There are 7 days in a week. So, in 7 weeks, there are 7 x 7 = 49 days.
Finally, we multiply the number of hours per day by the number of days in 7 weeks:
19 hours/day x 49 days = 931 hours.
Therefore, a tiger will sleep approximately 931 hours in 7 weeks.
The correct answer is 882 to 980 hours.
To calculate the number of hours a tiger will sleep in 7 weeks, we need to multiply its average daily sleep time (18 to 20 hours) by the number of days in a week (7), and then multiply that result by the number of weeks (7).
First, let's find the minimum and maximum hours a tiger sleeps in a day:
Minimum sleep time per day: 18 hours
Maximum sleep time per day: 20 hours
Now, let's calculate the minimum and maximum number of hours a tiger will sleep in a week:
Minimum sleep time per week: 18 hours/day * 7 days/week = 126 hours/week
Maximum sleep time per week: 20 hours/day * 7 days/week = 140 hours/week
Therefore, a tiger will sleep between 126 and 140 hours in 7 weeks.
