Answer:
y = 5.18
Step-by-step explanation:
replace x in the equation with 3.5
y = -0.72x + 7.7
y = -0.72(3.5) + 7.7
y = -2.52 + 7.7
y = 5.18
 
        
                    
             
        
        
        
Answer:
7033 / 10 000
Step-by-step explanation:
x = .70330 
10 000 x = 7033.0   divide both sides by 10 000
x = 7033 / 10 000

Answer:
9
Step-by-step explanation:
I think what they are asking is to subtract the 3 tokens from 21 tokens he already has giving us 18. and since it says "Twice the number of tokens" I'm assuming you divide 2 from 18 giving you 9 tokens.
 
        
             
        
        
        
The volume of the pyramid is 2496 cu.m.
<h3>What is a Pyramid ?</h3>
A pyramid is a three dimensional structure which has a polygon base and  in general triangular faces which join at the top .
It is given that 
A pyramid  has a 4 m by 4 m square top
 has a 4 m by 4 m square top
Height = 12 m 
Base = 20 m
The volume of a square pyramid with a   is given by
 is given by
V = (1/2) * ( Area of base + Area of   ) * height of the
 ) * height of the   from the base
 from the base
V = 0.5 * ( 20 *20 + 4*4 ) * 12 
V = 2496 cu.m
The volume of the pyramid is 2496 cu.m.
