 = 0.03×100
  = 3 %
        
             
        
        
        
Answer:
30%
Step-by-step explanation:
So, 20/20 turns to 14/20. How much was taken away? 6/20. What times 20 is 100? 5. So, 5 x 6 is 30. So, there is a 30% decrease
 
        
             
        
        
        
50 + 5w + 20m
The constant is 50.
A coefficient is 5 and another is 20.
A variable is w and another is m.
        
             
        
        
        
Answer:
<h2>C</h2>
Step-by-step explanation:
Following the Pythagoras theorem
SohCahToa
meaning Soh - sine , opposite , hypotenuse
Cah - cos , adjacent , hypotenuse
Toa - tan , opposite ,adjacent
so , therefore sin B is correct,
- tan B is also correct,
- cos B is incorrect , the correct answer suppose to be 6/10
- cos C is correct ,
