Answer:

 = 3sqrt(10)

Step-by-step explanation:

The distance between two points is found by

d =sqrt( x2-x1)^2 + (y2-y1)^2)

 = sqrt( 0--9)^2 +(-7--4)^2)

 = sqrt( (9)^2 + (-7+4)^2)

 = sqrt(9^2 + (-3)^2)

  = sqrt(81+9)

  = sqrt(90)

We know that sqrt(ab) = sqrt(a) sqrt(b)

  = sqrt(9) sqrt(10)

 = 3sqrt(10)

Here is how I completed the problem:

I started by creating a ratio:

\frac{x}{0.18} + \frac{360}{0.10} = \frac{x+360}{0.15}

<em>Where 'x' is the desired amount of the 18% solution of sulfuric acid. 

</em>From here, I solved for 'x':
<em>
</em>\frac{0.10x}{0.018} + \frac{360(0.18)}{0.018} = \frac{x+360}{0.15}
\frac{0.10x}{0.018} + \frac{64.8}{0.018} = \frac{x+360}{0.15}
\frac{0.10x+64.8}{0.018} = \frac{x+360}{0.15}
0.15(0.10x+64.8) = 0.018(x+360)
0.015x+9.72 = 0.018x+6.48
0.003x = 3.24
x = 1080

∴You will need to add 1080ml of 18% Sulfuric Acid in order to obtain a 15% solution.
