Answer:
111101011 subscript 2
Step-by-step explanation:
491 / 2 = 245 , 1 remainder
245 / 2 = 122 , 1 remainder
122 / 2 = 61 , 0 remainder
61 / 2 = 30 , 1 remainder
30 / 2 = 15 , 0 remainder
15 / 2 = 7 , 1 remainder
7 / 2 = 3 , 1 remainder
3 / 2 = 1 , 1 remainder
1 / 2 = 0 , 1 remainder
Now, we're going to put the remainders together in reverse order to get the final answer. 
111101011 ---> this is the final solution
See the image below for how you would write 111101011 subcript 2.

Answer:
2y -x + 6 = 0 
Step-by-step explanation:
Here a equation and a point is given to us and we are interested in finding a equation which is perpendicular to the given equation and passes through the given point . 
The given equation is ,
 
 
 
 
Firstly convert this into slope intercept form , to find out the slope of the line. 
 
 
 
 
 
 
 
 
Now on comparing it to slope intercept form which is y = mx + c , we have ,
And as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be negative reciprocal of the slope of the given line. Therefore ,
 
 
Now we may use the point slope form of the line to find out the equation of the line using the given point . The point slope form is,
 
 
Now on substituting the respective values we have,
 
 
 
 
 
 

 
        
             
        
        
        
Answer:
b = 22 m
Step-by-step explanation:
The formula for calculating the area (A) of a triangle is
A =  bh
 bh
multiply both sides by 2 to eliminate the fraction
2A = bh ( divide both sides by h )
b =  , hence
, hence
b =  =
 =  = 22 m
 = 22 m
