So only 1/10 of 4000 markers arrived.
So 1/10, or 0.1 of 4000, can be found by multiplying 1/10 by 4000.
1/10 * 4000 = 400
So she received 400 markers.
Answer:
1. 280/11
2. 1700/11
3. 280/11
4. 3600
5. 360
Step-by-step explanation:
Let n = sides of a regular polygon
For these problems, n = 22 because there are 22 sides.
I am going to write the formulas needed for each question below.
- 360/n
- 180 - 360/n
- 360/n
- 180(n-2)
- 360 (isn't affected by n)
To solve, just plug in N with 22.
These formulas are very easy to prove and I recommend if you have time try to prove these.
First, we are going to determine the number of drops that needs to be administered by dividing the total volume by the volume per drop. Since, 1 cc (cm³) is equal to 1 mL then, 1000 cc is equal to 1000 mL.
n = (1000 mL)(15 drop/1 mL) = 15000 drops
Then, divide the number of drops by the number of drops per minute.
N = (15000 drops)/ (50 drop/min) = 300 mins
Answer: 300 mins or 5 hours
