You need to set the correct porportion. x is the percent value you want to find. 100 is the maximum percentage. 420mg is what was taken out of the maximum 560mg dose.
You will cross multiple.
you will divide 42000 by 560
The complete answer will be: The patient took 75% of the 560mg dose of medication.

Answer:
The answer to each question is:
- A.) 403.2
- B.) 100. 8
Step-by-step explanation:
A.) To obtain the area of the dodecagon, you can use the next formula:
- Area of a dodecagon = 6 * apothem * edge
In the exercise, we have the edge (6 cm), but, to find the apothem of a dodecagon, that is the distance between the center of the polygon, and the middle point of each side, you can use the next formula:
- Apothem = Edge *
If we replace the value of the edge, we obtain:
- Apothem = 6 cm *
- Apothem = 11.2 cm (approximately).
With this data, we can find the area:
- Area of a dodecagon = 6 * apothem * edge
- Area of a dodecagon = 6 * 11.2 cm * 6 cm
- Area of a dodecagon = 403.2
Then,<u> the area of the dodecagon is 403.2 </u><u> approximately</u>.
B.) As the area obtained is for 12 pieces, when the parents ate 9 pieces, just left 3 pieces, with these values you can make a rule of three.
If:
- 12 pieces = 403.2
- 3 pieces = X
Then:
- X = (3 * 403.2
) / 12
- X = 1209.6
- X = 100. 8
In this form, <u>when the cookie has 3 pieces, its area is 100. 8 </u><u> approximately</u>.
