Answer:
Son 27 flores amarillas, redondeando*
Step-by-step explanation:
pues pongamos de constante f, entonces la formula sera 4f+5f=48 luego de esto seguira 9f=48 lo que dara como respuesta 5,3; reemplazamos la constante por 5,3 lo que quedaria como: 4x5,3 que es igual a 21,2 (el numero de flores rojas); luego reemplazamos la constante en 5f lo que quedaria como 5x5,3 lo que da 26,5 pero si lo redondeamos nos da 27 y listo uwu
Answer:
There are 24 boys and 4 teachers.
Step-by-step explanation:
To get 18, you multiply 3 by 6. To get 24, you multiply 4 by 6.
You add 18 and 24 together to get 42, which is double 21 and there are 2 teachers for every 21 students

Answer:
B you need to plug it in the calculator
The dirty little secret about trig is students mostly just need to understand the 45/45/90 right isosceles triangle and the 30/60/90 triangle, which is half an isosceles triangle.
I'm sure you have seen it many times already, so I'll remind you in the 30/60/90 right triangle the sides opposite those angles are respectively in the ratio
. Remember the smallest side is always opposite the smallest angle, etc. These make a right triangle because
So in this hypotenuse 2 triangle, the length 1 side is opposite the 30 degree angle and the
side is adjacent to it.
We could jump right to the answer but let's enumerate all the trig functions. Really you should memorize the sine and cosine so you can get these quickly.
We want the cotangent, another way to get it is
