Achemist needs 70 milliliter of 29% solution but has only 19% and 33% solutions available. find how many milliliter of each that should be mixed to get the desired solution

Step-by-step explanation:

Let x represent the volume in mL of 33% solution needed. Then 70-x is the volume of 19% solution required. The total amount of solute is ...

  0.33x + 0.19(70 -x) = 0.29(70)

  0.14x = 70(0.29 -0.19)

  x = 70(0.10/0.14) = 50

50 mL of 33% solution should be mixed with 20 mL of 19% solution to get the desired mix.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
