Correct answer get the BRAINLIEST ANSWER!
OLga [1]
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.

How do i do this question? someone help
lesya [120]
There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60
