Answer:
(0,1) (0.333,0)
(7,0)
m=1
Step-by-step explanation:
Let x be the number of mm of pure alcohol to be added:
I will add the mm to express the volume in mm
100mm.(19%) + (100%).x mL = (100 mL+x mL).(40%).
Now right again without the %
100.(0.19) + x.(1) = (100+x).(0.4)
19 + x = = 40 + 04x
x - 0.4x = 40 - 19
0.6 x = 21
x = 21/0.6 and x = 35 mL. This te quantity of pure alcohol should to be added to get a solution at 40%.

Answer:
16 times
Step-by-step explanation:
The question is basically asking :
<em>what number multiplied with the least amount would give me the greatest amount??</em>
<em />
<em>Let that number be x, so we can say:</em>
<em>least amount * x = greatest amount</em>
<em />
From the plot, we can see that least amount is 1/8 inches
The greatest amount is 2 inches
Now we can put it into the formula and find x:
1/8 * x = 2
x = 2/(1/8)
x = 16
