The 40 ml solution is said to be created from 10 ml and 30
ml solutions. In mixture problems, we equate the final mixture to its
compositions given the concentration for each. A 10 ml has 20% acid and the 30 ml has C
(unknown). We can write the total liters for 10 ml as 10(.2) and 30(c) for the
30 ml. when two solutions were added, it should be equal to 40ml with 32% acid.
Therefore, it should be written as 10(.2) + 30(c) = 40(.32). The answer is A
Answer:
The correct answer is y = 20x.
Step-by-step explanation:
The correct answer is: C.5z
Further explanation:
A factor is a number that is multiplied with a number
Let us look at the options one by one
<u>A. z+5</u>
5 is not a factor as it is being added to z.
<u>B. z-5</u>
5 is not a factor as it is being subtracted from z.
<u>C.5z</u>
5 is a factor as it is being multiplied with the z and can be separated easily
Hence,
The correct answer is: C.5z

Two other ways to write 0.632 is to turn it into a percent. To turn 0.632 into a percent just multiply it by 100. You can do this simply by moving the decimal point to the right twice and adding the percent sign: 63.2%
Another way is by fraction form. To put in in fraction form just look at the decimal and see which is the last place. The last placement it a thousandth. So your denominator is automatically 1000. Then, you look at the decimal and write the decimal and disregard the zero. The fraction you get is 632/1000. Hope this answer helps and mark as brainliest!
