We are given that there
will be (1/2) a litre after the first pouring, so considering two successive
pourings (n and (n+1)) with 1/2 litre in each before the nth pouring occurs:
1/2 × (1/n) = 1/(2n)
1/2 - 1/(2n) = (n-1)/2n
1/2 + 1/(2n) = (n+1)/2n
(n-1)/2n and (n+1)/2n in
each urn after the nth pouring
Then now consider the
(n+1)th pouring
(n+1)/2n × 1/(n+1) =
1/(2n)
(n+1)/(2n) - 1/(2n) =
n/(2n) = 1/2
Therefore this means that after
an odd number of pouring, there will be 1/2 a litre in each urn
Since 1997 is an odd
number, then there will be 1/2 a litre of water in each urn.
Answer:

Roughly something like this. The y intercept is at (0,1). The x intercept is at (-.5,0). Another point is at (1,3).
Answer:
I think the answer is A
Step-by-step explanation:
The answer is:
The reason is:
bottom one is a square prism. the volume formula is l x w x h. 9 x 9 x 9
square prism : 729
then the top one is a triangular prism. which is 1/2b x a x a
so 3.5 x 9 x 9
triangular prism: 283.5
then add these 2 numbers
1012.5
B = w + 6
g = b + 2
w = 4
b = w + 6
b = 4 + 6
b = 10 <== 10 blue feathers
g = b + 2
g = 10 + 2
g = 12 <== 12 green feathers
