Answer: C
Step-by-step explanation:
This describes an expotential function
At t = 0, P = 70
Therefore, C = 70
P = 70 e^kt
Solve for k by plugging in (4,360)
k = 0.4094
plug in t(7 hours)
70 e^(0.4094*7)
The answer roughly equals C
If he uses 1/6 for 1/2 the wall he uses 2x as much for the whole wall. because none of the equations have x2 you can ÷1/2 because multiplying by 2 is the same as dividing by a half.
so the answer is 1/6 ÷ 1/2
Answer:

Answer:
the answer is 1,944
Step-by-step explanation:
all you have to do is multiply 9 and 18 then whatever you get there then you multiply 162 by 12 and you get the answer
Jones takes 8 hours , therefore in one hour he paints a fraction of 1/8
smith takes 6 hours, thus in one hour he paints a fraction of 1/6
When working together they paint a fraction of 7/24 in an hour.
After 2 hours they will have painted a fraction of (7/24) ×2 = 7/12
The remainder will be 5/12 which will be undertake by smith alone.
Smith will therefore take 5/12 ×6/1 = 2.5 hour or 2 hours 30 minutes
