Given
Alchemist wishes to mix a solution that is 10% acid.
She has on hand 6 liter of a 8% acid solution and wishes to add some 16% acid solution to obtain the desired 10% acid solution. H
To find: ow much 146 acid solution should she add?
Explanation:
It is given that,
Alchemist wishes to mix a solution that is 10% acid.
Let x be the amount o acid mixed to obtain the desired 10% solution.
Since she has on hand 6 liters of a 8% acid solution and wishes to add some 16% acid solution to obtain the desired 10% acid solution.
Then,
Hence, she should add 2 liters of acid solution.
The correct answer is Choice C.
Here are the steps to factor the expression:
30x^3 + 35x^2 + 10x
5x(6x^2 + 7x + 2)
5x(6x^2 + 3x + 4x + 2)
5x(3x(2x + 1) + 2(2x + 1))
5x(3x + 2)(2x + 1)
1/500 = 0.002
3 2/25 = 308%
2.6 = 2 6/10
0.25% = 0.0025
