Answer:
P =44 cm
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 = s^2
Taking the square root of each side
sqrt(121) = sqrt(s^2)
11 = s
We want to find the perimeter of a square
P = 4s where s is the side length
P = 4(11)
P =44 cm
So as you know, one gallon has 16 cups, and there's 7 days in a week. So, if you multiple 1.5 by 7 you would get 10.5 cups per week, then divide that by 16 and get .65625 gallons per week.
Answer:
It would be 7:50
Step-by-step explanation:
If she wakes up at 7:10 and it takes her 40 minutes, the end time would be 7:50
-6+4=-2
-100+45=-55
because you can't add two positive numbers together and get a negative so at least one of the numbers added has to be negative
