Answer:
64??? take it with a grain of salt but i think its 64
Step-by-step explanation:
There are 6 sides to a die and if its rolled twice thats 12 possible answers and then a standard deck has 52 cards so thats 12+52=64
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
I’m pretty sure it’s h because the lines meet in the x axis
Answer:
Step-by-step explanation:
ok
The answer is 0.
1/2x = -1/2x
Add 1/2x to both sides.
1x=0
Divide 1 to both sides.
x= 0
I hope this helps love! :)
