-1/4 + f/8 = 1/2.
The LCD is 8.  Rewrite this equation as    -8/4 + 8f/8 = 8(1/2) and then reduce the result:
-2 + f = =4
Then f = 6.
You should check this result.
        
             
        
        
        
Let's first find out their factors.
90's factors are : 

190's factors are :

The common factors of 90 and 190 are :
1,2,5 and 10. 
The greatest one among these is, 10. So the greatest factor of 90 and 190 is 10.

Answer:
   D  cos(N)
Step-by-step explanation:
In case you haven't remembered the fact that the sine of an angle is equal to the cosine of its complement (the other acute angle in a right triangle), you can always go back to the definitions.
   Sin = Opposite/Hypotenuse
   sin(L) = NM/NL
and 
   Cos = Adjacent/Hypotenuse
   cos(N) = NM/NL = sin(L)
The equivalent of sin(L) is cos(N).
 
        
             
        
        
        
Answer:
0.3 or 3/10 
Step-by-step explanation:
a/b = -1/4 / -5/6
=> -1/4 * -6/5
=> 6/20 
=> 3/10 in simplest form.
