Answer:  12.5 CC
Step-by-step explanation:
V=1/3Bh where B is the area of the base and h is the height
The perimeter of the square base is 8.6 so each side is 2.15 and the area of the base is (2.15)^2 or 4.6225
V=1/3(4.6225)(8.1)=12.5cc
 
        
             
        
        
        
Answer:
I think so.
Step-by-step explanation:
If you do the math 2(5-3) exponent 2 - 4 = 4
So if y is 4 you should be correct!
Thb I think you need to know the value of y to solve this question.
 
        
             
        
        
        
Answer:
36.75 feet below sea level
Step-by-step explanation:
Feet she descended in 25min
=0.5×25
=12.25
Therefore, the total feet she dived to
=12.25+24.25
=36.75
 
        
             
        
        
        
Answer:
C. Yes, 3.5.
Step-by-step explanation:
If there is a relationship of direct proportionality for every ordered pair of the table, then the constant of proportionality must the same for every ordered pair. The constant of proportionality ( ) is described by the following expression:
) is described by the following expression:
 (1)
 (1)
Where:
 - Input.
 - Input.
 - Output.
 - Output.
If we know that  ,
,  and
 and  , then the constants of proportionalities of each ordered pair are, respectively:
, then the constants of proportionalities of each ordered pair are, respectively:









Since  , the constant of proportionality is 3.5.
, the constant of proportionality is 3.5. 
 
        
             
        
        
        
the quotient =215.3 repeating. so, you would do the 646 ÷ 215.3
