Answer: b
Step-by-step explanation:
you start with 0 min- equals 24
1 min- 21
2 min- 18
3 min- 15
4 min- 12
5 min- 9
and so on- you look for the table that best describes that. x represents the minutes, and y represent the amount of water left in the sink.
 
        
                    
             
        
        
        
Answer:
12.5
Step-by-step explanation:
you can solve this by dividing 250/20=12.5 
 
        
             
        
        
        
The rule for the angle formed outside of circle by intersection show below is given by:
Angle formed outside=1/2(difference of intercepted arcs)
∠ACE=1/2(AE-BD)
∠ACE=53°
AE=233°
BD=x
Hence the formula for obtaining BD will be:
53=1/2(233-x)
The correct answer is A
        
                    
             
        
        
        
Answer:
c =  - d
 - d
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2A = b(c + d) ← divide both sides by b
 = c + d ← subtract d from both sides
 = c + d ← subtract d from both sides
 - d = c
 - d = c
 
        
             
        
        
        
Answer:
See below. 
Step-by-step explanation:
So we want to prove that: 

First, simplify √8. This is the same as: 

Therefore, our equation is now: 

Combine like terms on the left: 

The square root of something is the same as taking that number to the one-half power. Thus: 

Rewrite: 

And we're done!
