Answer:
The answer is 154.8 ml
Step-by-step explanation:
In this question, the amount of pure acid is 18% of the total solution, that is, 18% of 860 milliliters. So
0.18*860 = 154.8 ml
The answer is 154.8 ml
Answer:

Step-by-step explanation:
To find the slope of the perpendicular line, we must first find the slope of the given line.
This can be done by rearranging the equation into the slope intercept form.
2x +3y= -3
3y= -2x -3
y= -⅔x -1
Thus, the slope of the given line is -⅔.
The slope of the perpendicular line is the negative reciprocal of the given line.
Slope of perpendicular line 
What is slope-intercept form?
- y= mx +c, where m is the slope and c is the y-intercept
- This can be achieved by making y the subject of formula
Negative reciprocal
- The reciprocal of m is

- The negative reciprocal of m is

Negative reciprocal of -⅔

Answer:
<u>There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.</u>
Step-by-step explanation:
After reviewing the information given for solving the question, we notice that the number of adults and the number of children are two constants, where the number of children is the 75% of the number of adults (3/4 = 75%). In that case, for finding the number of children for every specific number of adults, we do the following calculations:
1. For 8 adults: Using the 75%, we multiply by it (8 * 75%) and we get that the number of children is 6.
2. For 12 adults: Using the 75%, we multiply by it (12 * 75%) and we get that the number of children is 9.
3. For 16 adults: Using the 75%, we multiply by it (16 * 75%) and we get that the number of children is 12.
4. For 20 adults: Using the 75%, we multiply by it (20 * 75%) and we get that the number of children is 15.
<u>There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.</u>
