Answer: 28
Step-by-step explanation:
Given
Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is 

for 36 serves, applying the same success rate, it is

Serves that did not make over the net is 
Thus, Kenny will make 28 serves that make over the net
 
        
             
        
        
        
Answer:
The slope would also be -4.
Step-by-step explanation:
This is because parallel lines have the exact same slope. Since these two lines are parallel and the first has a slope of -4, the second must as well. 
 
        
                    
             
        
        
        
343^1/3
=(7)^3*1/3 [ 3 and 3 are cancelled]
=7
        
             
        
        
        
<span>Here's the rule.  I'm SURE you learned it in Middle School.  Or, 
I guess I should say:  I'm SURE it was taught in Middle School.
                  Vertical angles are equal.
"Vertical angles" are the pair of angles that don't share a side,
formed by two intersecting lines.
AND ... even if you forgot it since hearing it in Middle School,
it was clearly explained in the answer to the question that
you posted 9 minutes before this one.
In #8, 'x' and 'z' are vertical angles.
         'y' and 116° are vertical angles.
In #9, 'B' and 131° are vertical angles.
In #10, 'B' and 135° are vertical angles.
For all of these, it'll also help you to remember that all the angles
on one side of any straight line add up to 180°. </span>
