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
200, because the more samples you have the more correct you will be.
Normally I'd love to help, but put in a picture. I'm confused.
Answer:
4.
°
Step-by-step explanation:
Given:
The tangent of the angle is given as:

Since the angle is negative, it means that it is measured in the clockwise direction as angles measured in clockwise direction are negative and that measured in counter clockwise directions are positive.
-212° when measured from counter clockwise direction will be equal to:

Therefore,
= 
Now, we have the identity for tan as:

Here, 
Therefore,

Hence,
=
=
