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.

22 = 2 · 11
2 is even
11 is odd
LCM(2; 11) = 22
but we have other answer:
22 = 1 · 22
22 is even
1 is odd
LCM(1; 22) = 22
Answer: 2 and 11 or 22 and 1.
SAME: Both measure a circle
DIFFERENT: Circumference measures AROUND the circle and the area measures the entire circle.
Answer: 1.) The triangles are congruent, B.) ARO=DHT by SAS Postulate
Step-by-step explanation:
SAS applies because there are 2 corresponding sides with an angle inbetween
SSS would apply if there are 3 congruent sides
ASA would apply if there were 2 corresponding angles with a side inbetween
