Rate of fill-up = 1/44 = 1/44 * 77/77 = 77/3388
Rate of emptying = 1/77 = 1/77 * 44/44 =44/3388
Combined Rate of Fill-up = 77/3388 - 44/3388 = 33/3388 = 3/308
Time for combined fill-up = 308/3 = 102.6667 hours = 102 hours and 40 minutes
Explained the mistake and correct answer in photo.
Given:
Length of chords of one segment = 11 and 8
Length of chords of other segment = 2 and x
To find:
The value of x.
Solution:
<em>If two chords intersect each other inside a circle, the products of length their segments are equal.</em>



Divide by 2 on both sides.


Switch the sides.

The value of x is 44.
the answer: b=9 hope this helps!
(X+1)(x-6) I think is what you’re asking for?
