Yes, as one half or 1/2 is also 10/20. 11/20 is greater than half by a 10% margin.
Answer:
5mL would be required to provide a patient with 0.25 mg of the drug substance.
Step-by-step explanation:
The problem states that an injectable solution contains 25μg of a dug substance in each 0.5 mL, and asks how many milliliters would be required to provide a patient with 0.25 mg of the drug substance.
So, the first step is the conversion of 25ug to mg, since the problem asks the answer in mg.
Each mg has 1000ug. So
1mg - 1000ug
xmg - 25ug
1000x = 25

x = 0.025 mg
It means that each 0.5mL of the solution contains 0.025mg of the drug. How many milliliters would be required to provide a patient with 0.25 mg of the drug substance.
0.5mL - 0.025mg
xmL - 0.25mg
0.025x = 0.5*0.25

x = 10*0.5
x = 5mL
5mL would be required to provide a patient with 0.25 mg of the drug substance.
Values of x and y will be 12 and 5 respectively.
It's given in the question,
- Three points Q, R and S are collinear.
- Coordinates of Q → (2, 0)
- Coordinates of R → (8, 3)
- Coordinates of S → (x, y)
- QR : RS = 3 : 2
Since, expression for the coordinates of a point (h, k) which divides the segment joining points
and
in the ratio of m : n is given by,
h = 
k = 
Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,





Similarly, 



Therefore, values of x and y will be 12 and 5 respectively.
