Answer:
24 minutes
Step-by-step explanation:
Given
Ashley = 12 minutes
Becky = 8 minutes
Required
Determine when they will be at the same point again
To do this, we simply determine the least common factor of both.
Ashley = 12, 24, 36, 48....
Becky = 8, 16, 24, 32........
From above, the least common factor is 24
<em>Hence, both of them will be at the starting point in 24 minutes</em>
Answer:
2.5 or
Step-by-step explanation:
5 x = 2.5
This is because half () of 5 is 2.5
2.5 as a fraction is .
Hope this helps!
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:
what
Step-by-step explanation:
It says that b represents Becky’s score and c represents Cathy’s score.
Becky’s score was 5 less than Cathy’s score, its equation can be written as :-
b = c - 5
It says that their combined score totaled 185, its equation can be written as :-
b + c = 185
So, correct pair of equations is b = c - 5 and b + c = 185.
