The intersecting chord theorem says
![AY \cdot BY = CY \cdot DY](https://tex.z-dn.net/?f=%20AY%20%5Ccdot%20BY%20%3D%20CY%20%5Ccdot%20DY%20)
![AY = \dfrac{ CY \cdot DY}{BY} = \dfrac{6 \cdot 12}{9} = 8](https://tex.z-dn.net/?f=%20AY%20%3D%20%5Cdfrac%7B%20CY%20%5Ccdot%20DY%7D%7BBY%7D%20%3D%20%5Cdfrac%7B6%20%5Ccdot%2012%7D%7B9%7D%20%3D%208)
![AB = AY + BY = 8 + 9 = 17](https://tex.z-dn.net/?f=AB%20%3D%20AY%20%2B%20BY%20%3D%208%20%2B%209%20%3D%2017)

Answer:
C. 4(5c-2d)
Step-by-step explanation:
![20c - 8d \\ = 4(5c - 2d)](https://tex.z-dn.net/?f=20c%20-%208d%20%5C%5C%20%20%3D%204%285c%20-%202d%29)
Answer:
1/8
Step-by-step explanation:
1st day......1/3
2nd day....1/6
3rd day....3/8
common denominator of 24
1/3 + 1/6 + 3/8 = 8/24 + 4/24 + 9/24 = 21/24 (this is water used)
that means that : (24/24 - 21/24) = 3/24 reduces to 1/8 .....water in the tank
