Answer:
B 18.38
Step-by-step explanation:
log4x = 2.1
logx/log4 = 2.1
logx = log(4) x 2.1
logx = 1.2643
x = antilog(1.2643)
x = 18.38 (to 2 d.p)
 
        
                    
             
        
        
        
Answer:
Her next step would be to add 12 to both sides of the equation
Step-by-step explanation:
Which would make the equation 4x=28 
Then you divide both sides by 4 giving you x=7
 
        
                    
             
        
        
        
The given radius is = 60 feet
The volume of the sphere is given by = 
So we will find the volume of the sphere using radius as 60 and pi as 3.14
Volume =  = 902059.20 cubic feet
 = 902059.20 cubic feet
As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.
So volume of quarter sphere = 
= 225514.80 cubic feet
And rounding this to nearest whole number we get 225515 cubic feet as the answer.
 
        
             
        
        
        
The answer would be 73.86
