Star at -20 and go back by -5 on the number line
Answer:
The concentration is simply 36%
Step-by-step explanation:
In this question, we are concerned with calculating the concentration of a new mixture formed from mixing some liters of each of two vinegar variants of different concentrations.
We proceed as follows;
The concentration of the new solution will contain 12% of 13L vinegar A and 70% of 9L vinegar B
13L of vinegar A will contain 13 * 12% = 13 * 0.12 = 1.56
9L of 70% vinegar B will contain 9 * 70% = 9 * 0.7 = 6.3
Now, the new mixture has a total volume of 13 + 9 = 22L
The concentration of the new mixture will thus be;
(1.56 + 6.3)/22
= 0.357 and that’s approximately 0.36 or simply 36%
All you have to do is multiply them!make sure to turn them into improper drafting before tho!
Taxes you have to pay extra because of taxes
<span>1.69 divide by 1000</span><span> =0.00169
169/100 = 1.69 meters
1690/1000=1.69
so the first one is not same
hope it helps</span>
