The proportion would be -
12 / 150 = x / 225.
That is, 12 per 150, x amount per 225
To solve this proportion, you can cross multiply (multiply the values diagonally) -
12 / 150 = x /225
150x = 12(225)
150x = 2700
x = 18
18 vials are required to treat 225 people.
Hope this helps! (:
Answer:
1 / 10 L
Step-by-step explanation:
Litres of citric acid solution = 3/5
Fraction of solution used = 1/6
1/6 of 3/5
1/6 * 3/5
= (1 * 3 / (6 * 5)
= 3 / 30
= 1/ 10
- The solution for the compound inequality is:

- The graph is given at the end of the question.
--------------------------------
The compound inequality is given by:

Thus, we need:
and 
That is, values of x that respect both these conditions.
--------------------------------
For the first inequality:




--------------------------------
For the second inequality:




--------------------------------
- Considering that both conditions are needed, the solution is:

- The graph on the number line is given next.
