Answer:
r= ![2\sqrt{2}](https://tex.z-dn.net/?f=2%5Csqrt%7B2%7D)
r= -![2\sqrt{2}](https://tex.z-dn.net/?f=2%5Csqrt%7B2%7D)
Step-by-step explanation:
8=![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
Square root both sides of the equation.
r= ![2\sqrt{2}](https://tex.z-dn.net/?f=2%5Csqrt%7B2%7D)
r= -![2\sqrt{2}](https://tex.z-dn.net/?f=2%5Csqrt%7B2%7D)
Beans A= x
Beans B=(110-x)
0.08x+0.32(110-x) = 0.27(110)
Solve for x
0.08x+35.20-0.32x = 29.70
0.08x-0.32x=29.7-35.2
−0.24x=−5.5
X=5.5÷0.24
X=22.9 of Beans A
110−22.9=87.1 of Beans B
This is reasonable if one can weigh beans to the nearest tenth of a pound.
Hope it helps:-)
