Answer:
each dose = 6.7 mL ( to 1 decimal place)
Step-by-step explanation:
Total volume of vial = 20mL
each dose of vial = 1/3 of the total volume
let us express this fraction as a real number:
1/3 of 20 = 1/3 × 20
Since we are to express the answer as a decimal, let us convert the fraction to decimal:
1/3 = 0.3333
∴ 1/3 × 20 = 0.3333 × 20 = 6.667 mL
since we are dealing with drugs, it'll be appropraite to express the answer to 1 d.p
∴ each dose = 6.7 mL

Answer:
The below attached graph shows the given inequality.
Step-by-step explanation:
Here, the given inequality,
x - 2y > -12
Since, related equation of the inequality,
x - 2y = -12
Which is a line passes through (-12, 0) and (0, 6)
Also, '>' represents dotted line,
So, join these two points by dotted line in the coordinate plan,
Now,
0 - 2(0) > -12 (True)
i.e. shade the region of the line that contains origin.
By the above explanation we will get the graph of given inequality ( shown below )
