A) If 9 students sharpen 18 pencils in 2 minutes,Then if the time is halved, it will take twice as many men to sharpen 18 pencils.Hence it will take 18 students to sharpen 18 pencils in one minute B) y & 1/x. Then y = K/x where K is our constant of proportionality.Then K = yx. When x = -64 and y = -16 then K = -64 * -16 = 1024. Option DC) When x = 3 y = 8. So for an inverse variation K as calculated from B = 3 * 8 = 24.Then when K = 24 and y = 6; we have 24 = 6x. Hence x = 4. Option A
        
             
        
        
        
Answer:
playing surface=plane
corner of serving box=vertex
baseline=line segment
net=plane
intersection of baseline and side line=vertex
Step-by-step explanation:
what I remember from my geometry course, super sorry if any are wrong
 
        
             
        
        
        
Length + width = 1/2 the perimeter:30/2 = 15
Area = length x width
 List the factors of 50: 1, 2, 5, 10, 25, 50.
Find the two factors that when added together equal 15:
 Dimensions are 5 cm by 10 cm.
 
        
                    
             
        
        
        
The answer is 3! 
explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!
