I believe that the answer is 7 or i may be wrong.
The answer is A.
If you divide 4 into all of the answers the only answer that will give you a whole number is 36. example 36/4 = 9
This is fairly simple. You would just substitute the answer choices in for 'n'.
3^-243=0
So, A. isn't correct.
3^-27=1.31137265.....
So, B. isn't correct.
3^-4=0.123456789 In fraction form this is 1/81
So, we think C. is the correct answer, but just to be sure, let's try D.
3^4=81 In fraction form this would be 81/1.
So, C. is our answer.
Hope this helps!!
Answer:
Volumetric flow rate = 
Step-by-step explanation:
The volumetric flow rate v= area x velocity
from the given data we will find out area and velocity first.
Area = A = (π /4) d^2
Diameter = d = 15 cm = 0.15 m
Area = A = 
The velocity = V = 
height of wine in the tank = H = 2.5 m

Now calculating the volumetric flow rate
v = A x V
v = 0.0176 x 7
