Answer:
6:00 or 6 o'clock
Step-by-step explanation:
1) Add 2 to the hours. So, 3+2=5
2) Add 15 minutes to 45 minutes. So, 15+45=60
3) 60 minutes is an hour, so therefore add one more hour. 5+1=6
4) There are 6 hours and 0 minutes.
So, the time that Renita finished her homework was 6:00.

9 hours because 8 x 3 = 24 and 3 x 3 = 9
Answer:
Cost of 4 muffins = $3.45
Cost of 12 muffins = (3 sets of x 4 muffins = 12)
Cost of 3 sets of muffins = $3.45 x3 = $10.35
Step-by-step explanation:
Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
