inverse means opposite,
inverse of addition is subtraction
Answer:
- 273 mL of 5%
- 117 mL of 15%
Step-by-step explanation:
Let q represent the quantity of 15% dressing used. Then the amount of 5% dressing is (390 -q). The amount of vinegar in the mix is ...
0.15q + 0.05(390 -q) = 0.08(390)
0.10q = 31.2 -19.5 = 11.7 . . . . . . subtract 0.05(390) and simplify
q = 117 . . . . . . . . . . . . . . . . . . multiply by 10
390-q = 273
The chef should use 273 mL of the first brand (5% vinegar) and 117 mL of the second brand (15% vinegar).

<em>Additional comment</em>
You may have noticed that the value of q is (0.08 -0.05)/(0.10 -0.05)×390. The fraction of the mix that is the highest contributor is the ratio of the difference between the mix value and least contributor, divided by the difference between the contributors: (8-5)/(15-5) = 3/10, the fraction that is 15% vinegar. This is the generic solution to mixture problems.
Answer: The answer is 43.
Step-by-step explanation: Given that there is a quart, in which there are 946 millilitres and 22 pints. We are to find how many millilitres are there in a pint.
For that, we just need to divide number of milliliters by the number of pints in the quart.
Let us start as follows -
In 22 pints of the quart = 946 millilitres.
Therefore, in 1 pint of the quart = 946/22 = 43 millilitres.
