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
Answer:
64.0874 or 20.41pi
Step-by-step explanation:
circumference = diameter x pi
C = D x pi
C = 20.41pi(lets say pi is 3.14)
C = 64.0874
You can split this into 2 shapes.
1 of the shapes will be a small square. The dimensions for it would be 4 by 3 (12)
The second shape, the bigger rectangle has the dimensions, 12 by 6 (72)
Now add these two values 12+72 and you get, 84
you answer is A 84 square inches
Answer:
yes
Step-by-step explanation:
I think it would be 64/100 because 64 percent is most likely out of 100 percent
