Answer:
Step-by-step explanation:
A circle is 360 degrees. What we are asked in words is, "How many degrees is 40% of 360?" Let x be "how many degrees"; the word "is" means =; 40% as a decimal is .4; the word of in this context means to multiply; and 360 is just 360. Putting all that together into an equation we can solve for x:
x = .4(360) so
x = 144
Adventure movies covers 144 degrees of that circle.
 
        
                    
             
        
        
        
Answer:
D
Step-by-step explanation:
If x is not equal to zero, then 1/x can be equal to x.
So which is k * 1/x if x =1?
D, because x is the same as 1x, which is equivalent to 1/1 (x).
