Find the equation of the line shown.
kipiarov [429]

Answer:

The line passes through (1,1) and (3,2). Therefore, its equation is

y -1 = \frac{2-1}{3-1} (x-1)\\or, y-1 = \frac{1}{2} (x-1)\\or, 2y-2 = x-1\\or, x-2y-1+2=0\\or, x-2y+1=0

Marie mixes 20 liters of 12% acid solution with a 36% acid solution to make a 20% acid solution. How many liters of 36% solution
kykrilka [37]
Use c1v1+c2v2=c3v3
where c=concentration, v=volume.

C1=0.12
V1=20 L
C2=0.36
V2=X
C3=0.20
V3=20+X L

Substitute in equation
0.12(20) + 0.36X = 0.20(20+X)
Expand 
2.4 + 0.36X = 4 + 0.2X
Simplify
(0.36-0.2)X = 4-2.4
0.16X = 1.6
X=1.6/0.16 = 10 L

check:
0.12(20)+0.36(10)=2.4+3.6=6.0
(20+10)*0.20 = 6.0  so solution is good.

Answer: Volume of 36% solution is 10L
