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.

Given the question:
The manager of a baseball team has 15 players to choose from for his
9-person batting order. How many different ways can he arrange the
players in the lineup?
5,005
362,880
3,603,600
1,816,214,400
The number of was in which a smaller group is choosing from a bigger group is given by the bigger number combination the smaller number.
Here, we want to choose a 9-person batting order from a team of 15 players. This is given by:
Answer:
4-6i has coordinate (4,-6), and -4+2i has coordinate (-4,2)
Step-by-step explanation:
The real part of the number represents the x coordinate, the imaginary part is the y coordinate, so 4-6i has coordinate (4,-6), and -4+2i has coordinate (-4,2)
Ok so you first you move the 2h to the top and and 兀r is multiplied by ten of course and then you get the answer <span>兀r 34029h</span>
