Answer:
Step-by-step explanation:
Set it up as a proportion in correspondence with their unit of measurement:
![\frac{16}{21,3} = \frac{25}{?} → \frac{[21,3][25]}{16} → \frac{532,5}{16} = 33,28125 \\ \\ 33,3 ≈ P](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%2C3%7D%20%3D%20%5Cfrac%7B25%7D%7B%3F%7D%20%E2%86%92%20%5Cfrac%7B%5B21%2C3%5D%5B25%5D%7D%7B16%7D%20%E2%86%92%20%5Cfrac%7B532%2C5%7D%7B16%7D%20%3D%2033%2C28125%20%5C%5C%20%5C%5C%2033%2C3%20%E2%89%88%20P)
I hope this is correct, and as always, I am joyous to assist anyone at any time.
Answer: s = 180 °
Step-by-step explanation:
Arc AC has that many degrees. If the angle is ABC, where B is also on the circle, this is called an inscribed angle, with vertex (its”point”) at B. Now, arc AC will have exactly twice the degree measure of angle ABC. That is a theorem in geometry textbooks, which has been known for about 2500 years!
Answer:
300 students
Step-by-step explanation:
If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.
195/65= 3
So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.
If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.
3x100=300
We can check this by finding 65% of 300, and seeing if that is 195.
300x.65=195
It does check out.
