Answer:
100% --- x
75% --- 18
knowing that you have to multiply the 100 with 18 and 75 with x
75x = 100 . 18
75x = 1800
x = 1800 : 75
x = 24
Step-by-step explanation:
so there are 24 people in the classroom
Answer:
![cos(tan^{-1}(0))=1](https://tex.z-dn.net/?f=cos%28tan%5E%7B-1%7D%280%29%29%3D1)
Step-by-step explanation:
Evaluate cos(tan^-1 0)
![cos(tan^{-1}(0))](https://tex.z-dn.net/?f=cos%28tan%5E%7B-1%7D%280%29%29)
We know that tan(0)=0
tan (0 degree)=0
![tan^{-1}(0)=0](https://tex.z-dn.net/?f=tan%5E%7B-1%7D%280%29%3D0)
Replace it in our problem
![cos(tan^{-1}(0))](https://tex.z-dn.net/?f=cos%28tan%5E%7B-1%7D%280%29%29)
![cos(0)](https://tex.z-dn.net/?f=cos%280%29)
At 0 degree the cos value is 1
So co(0)=1
![cos(tan^{-1}(0))=1](https://tex.z-dn.net/?f=cos%28tan%5E%7B-1%7D%280%29%29%3D1)
Distributive property states that z(x + y) = zx + zy.
25(x - y) = 25x - 25y
Answer:

Step-by-step explanation:
What is the question
Answer:
-1 1/8
Step-by-step explanation:
-3/4 / -8/12
= -3/4 * -12/8
= -3*12 / -4*8
= -36/32
= -1 4/32
= -1 1/8
