You need 320 ml of a 65% alcohol solution. on hand, you have a 60% alcohol mixture. how much of the 60% alcohol mixture and pure alcohol will you need to obtain the desired solution?
you will need
ml of the 60% solution
and
ml of pure alcohol.

You will need

280 mL of the 60% solution

and  40 mL of pure alcohol.

Step-by-step explanation:

Let 'x' be the amount of 60% alcohol solution and y the amount of pure alcohol.

Therefore:

(0.6x + y)/320 = 0.65 ⇒ 0.6x + y = 208

x + y = 320

Solving the sistem of equations:

x = 280 and y = 40

Therefore, You will need

280 mL of the 60% solution

and  40 mL of pure alcohol.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
