Answer:
|BC| = 9.4 m
Step-by-step explanation:
Angle bxy = angle abc (reason, corresponding angles)
Angle ayx = angle acb ( reason , corresponding angles)
So angle abc= 62°
Angle acb = 51°
Angle acb + and + bac = 180 (reason, sum of angles in a triangle)
Anlge bac = 180-62-51
Angle bac= 180-113
Angle back = 67°
Using sine formula
|BC| /sin 67 = 9/sin 62
|BC| = sin 67 *9/sin62
|BC| = 9.4 m
 
        
             
        
        
        
Answer: 3/2
Step-by-step explanation: Rate of change is the same thing as the slope. 
 
        
             
        
        
        
12.04 meters is 474 inches so 12 would be closest
        
             
        
        
        
Answer:
1. c      2. a     3. b
Step-by-step explanation:
The best way to prove these results are the right ones is by multiplying diagonally :
1.  1/3 = 4/12  -----> 1 . 12 = 12  ; 3 . 4 =12
2.  1/2 = 3/6 ------> 1 . 6 = 6  ;  2 . 3 = 6
3.  2/5 = 6/15 -----> 2 . 15 = 30  ;  5 . 6 = 30
The results of the multiplications must be the same if the fractions are equivalent.
 
        
             
        
        
        
3m - 5p = 12
3m(-3m) -5p = (-3m)+ 12
-5p = -3m + 12
(-5)/-5p = (-5)/ (-3m + 12)
p = 3/5m + 12/-5
