and we get

Answer:
3rd and 4th options are correct that is 24 hours per day and 7 days per week.
Step-by-step explanation:
We need to find the conversion factors that can be used to find number of hours in a week.
We know that,
Number of hours in a day = 24
and
Number of days in a week = 7
So, Number of hours in 7 days = 24 × 7 = 168.
Therefore, 3rd and 4th options are correct that is 24 hours per day and 7 days per week.
The area of rectangle ABCD should be 24. Since the length is 6 and the height is 4.
Answer:
110 / 3.6 = 30.555
Chance for yellow is about 31%
Orange is 70/3.6= 19.4444444
Orange is about 19%
Red is 40/3.6=11.11
Red is about 11
We divide by 3.6 because 360 degrees /100 percent = 3.6
The decimals are repeating so it is infinite decimal places
Yellow is about 31% (30.555555 for exact)
Orange is 19%(19.4444444 for exact)
Red is 11%(11.11111 for exact)
