Answer:
20.8
Step-by-step explanation:
The chord with length x is bisected by the perpendicular segment.
Use the Pythagorean theorem to find the length of half of x.
Let's call half of x, y.
y^2 + 6^2 = 12^2
y^2 = 144 - 36
y^2 = 108
y = sqrt(108)
x = 2y = 2sqrt(108)
x = 20.8

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just don’t want to waste my time in case you don’t want me to :)
Given:
let h be the high quality bean
let c be the cheaper bean
h + c = 160
6h + 3.25c = 160*4.97
6h + 3.25c = 795.20
h = 160 - c
6(160 - c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
-2.75c = 795.20 - 960
-2.75c = -164.80
c = -164.80 / -2.75
c = 59.92 or 60 lbs
h = 160 - c
h = 160 - 60
h = 100 lbs
Sarah should blend 60 lbs of cheap coffee bean and 100 lbs of high quality coffee bean.
