Answer:
- <em>0.75</em><em> liters of 5% hydrochloric acid solution </em>
- <em>0.25</em><em> liters of 45% hydrochloric acid solution.</em>
Step-by-step explanation:
Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.
As Rajan need total of 1 liter of solution, so
i.e 
--------------------1
As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so
i.e 
-------------2
Putting value of x from equation 1 in equation 2,
Putting the value of y in equation 1,
Therefore, Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.
F(x) is the same as y. so you’d choose two coordinates and do y2-y1 over x2-x1. id recommend doing that with whole numbers, no decimals. by doing that you get your slope.
Answer:
64x+132y= 1040 for the first part
Honestly, still have your friendship with your friend as they are more important to your life then the person you like or liked as it is only a crush. Crushes don’t last long. I guess you would still have that awkward feeling of having your friend date someone that you liked but in life you go through many different crushes and loves. You will get over them. It may affect you for a while but you will be completely fine. The situation that you are in would be worse if you dated their ex and lead to further complications. Just remember you should be happy in your life and shouldn’t have you world revolve around a single person especially if your in school / collage as you are young. Have a wonderful day!
