Answer:
9 females
Step-by-step explanation:
Original ratio is 5:3 meaning to get 15 males you need to multiply by 3
which gives you 15 males.
Now do the same for females and multiply by 3 giving you your answer
9!
180-45= 135, the answer is 135
The positive square root of 35
= 5.9160797831 because 5.9160797831^2 is 35
Therefore you multiply 5.9160797831 to 5.9160797831
