Answer:
24% saline
Step-by-step explanation:
Find how much saline is in both solutions:
7(0.27)
= 1.89
3(0.17)
= 0.51
Add this together:
1.89 + 0.51
= 2.4
Since there are 10 quarts in total, the concentration of the mixture can be found by dividing 2.4 by 10:
2.4/10
= 0.24
So, the concentration of the mixture is 24% saline
(5*180)/7=900/7=128.5714285714286
The angle is approximately 129 degrees.

Answer:
48in^3
Step-by-step explanation:
volume of rectangular prism formula: L*W*H
lets plug in values for:
l=length(3)
w=width(2)
h=height(8)
so
3*2*8=48
48in^3
Hope this helps!
