Answer:
k = -5 and i think the other one is k=0
Step-by-step explanation:
Let x be the amount (the volume in milliliters) of the 5% solution to be mixed.
Then the volume of the 1% solution is 100-x milliliters.
Then your "concentration" equation is
%280.01%2A%28100-x%29+%2B+0.05%2Ax%29%2F100 = 0.02,
or, equivalently,
100-x + 5*x = 200,
which implies
4x = 100 ----> x = 100%2Fx = 25.
Answer: 25 milliliters of the 5% solution must be mised with 100-25 = 75 milliliters of the 1% solution.
Answer:
She still has 60%
Step-by-step explanation:
First you make the 25 a 100 which is basically multiply by 4 which you should do the same for 10
so 40/100 is how much she game away
She gave away 40%
She still has 60%
The only way to do it is 1.8x1.8x1.8x1.8x1.8x1.8x1.8x1.8x1.8. Or just use a calculator. Sorry to let you down
Here is the solution for the problem:
<span>1m * 1m = 1m² </span><span>
<span>1m =
1,000,000µm = 1 x 10^6µm </span>
<span>1 x 10^6µm
* 1 x 10^6µm = 1m² </span>
<span>1x10^12µm²
= 1m² (Now, divide both sides by 1x10^12). </span>
<span>1x10^12µm²
/ (1 x 10^12) = 1m² / (1 x 10^12) </span>
<span>1µm² =
0∙000 000 000 001 m² (x both sides by 1.5). </span>
<span>1.5µm² =
0∙000 000 000 0015 m² </span>
1.5µm² =
1∙5x10^-12 m²</span>
So 1.50 micrometers^2 is equal to 1.5 x 10^-12 m². I am hoping that
