A cube has equal sides if they are 2÷ 1/2 each then L×W×H would be (2÷ 1/2)^3. To divide fractions we multiply the reciprocal.
2÷ 1/2 = 2/1 × 2/1 = 4
4×4 = 16×4= 64 
answer is V = 64 inches cubed.
        
             
        
        
        
To figure out the cost per cookie, divide $2.49 by 3. The cost per 1 cookie (column 1) would be .83 cents.
To figure out the cost of 20 cookies, multiply 20 x .83 cents. The answer is 20 cookies would cost $16.60
To figure out how many cookies would cost $145,25, divide $145.25 by .83 cents. The answer is 175 cookies would cost $145.25
 
        
             
        
        
        
Answer:
All Real Numbers except for 4
Step-by-step explanation:
Objective: Specify domain and range of a function. 
The equation is a linear equation. A linear equation range is all real numbers. However x cannot equal 1 so let plug in x to find where the y value CANT be.

So the range is 
All Real Numbers except for 4.
 
        
             
        
        
        
Answer:
I will attach the missing drawing with the answer.
9.b) 
Plane JKM
Plane JLM
Plane KLM
Step-by-step explanation:
The drawing for this question is missing. I will attach it with the answer. 
9.a) Plane JKL is not an appropriate name for the plane because all of three points lie in the same line. 
Through a line pass infinite planes. The plane JKL doesn't define a unique plane. That's why plane JKL isn't an appropriate name for the plane.
9.b) We can name the plane using three points that don't lie in the same line. 
Three possible names for the plane are :
Plane JKM
Plane JLM
Plane KLM
