Answer:
She still has to cut 1 3 /16
Step-by-step explanation:
Olivia wants to cut 3 3/4 inches from a piece of string. Converting 3 3/4 to improper fraction, it becomes 15/4 inches. 
She already cut off 2 9/16 inches converting to improper fractions it becomes 41/16 inches. 
15/4 - 41/16 = (60-41)/16 = 19/16 inches 
19/16 = 1.187 ~ 1
19 - (16 x 1) =3 
 
        
             
        
        
        
Triangle b because it only has 3 sides
        
             
        
        
        
I'm assuming you mean Cartesian plane. It is the same as a coordinate plane. There are two perpendicular lines with an x (horizontal) and y (vertical) axis.
