Answer:
..
Step-by-step explanation:
Answer: 30 students.
Step-by-step explanation: They are saying 50% of the class like the teacher. We know that 50% is half of the 100% so that mean only half of the students like the teacher. Is 15 students like the teacher it means that 15 are half of the students in the class. The other half should be another 15. So 15+15=30 or 15x2=30.
I hope I didn’t make it to confusing.
The ratio is 132:89.
If you'd like a ratio simplified, just divide like you would a fraction.
Unfortunately, 89 is a prime number, so your ratio stays the way it is.
Therefore your ratio is 132:89
We are given the expression sin (sin-1 (X) + cos-1 (y)). We use the associative property to distribute the sine function. sin (sin-1 (x)) is equal to x. cos-1 (y) is equal to beta, the other angle besides alpha. sin beta is also equal to x which means the simplified term is 2x. This makes sense because sin-1 x = cos-1 y
