one mixture contains 6 fluid ounces of water and 10 fluid ounces of vinegar. a second mixture contains 9 fluid ounces of water and 12 fluid ounces of vinegar. are the mixtures proportional? if not, how much water or vinegar would you add to the second mixture so that they are proportional?

No, they are not proportional

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
