Answer:
Height = 19mm.
Step-by-step explanation:
Area of a regular polygon =  (A * P) / 2 where A = side / (2 * Tan (π / N)) where, N = Number of sides, A = Apothem,  P = Perimeter.
Here A = 5, P = 5*12 = 60 so
 Area  of the base  = (5 * 60) / 2 = 150 mm^2.
Volume = area base * height so
Height = volume / area of base
             = 2850 / 150
             = 19 mm.
 
        
             
        
        
        
<span>Let C denote the number of candidates they interview and E the number of employees they train. 
</span>
<span>If it takes 20 hours and $400 to interview a candidate, then it takes 20C hours and $400C to interview C candidates.
</span>
If <span>it takes 120 hours and $3600 to train an employee, then it takes 120E hours and $3600E to train E employees.
</span>
Company has less than <span>$95000, then 400C+3600E<95000.
</span>
Company <span>wants to spend at most 470 hours, then 

. 
</span>
<span>You obtain the system of two inequalities:
</span>

Then you can solve this system according to your demands.
 
        
        
        
First find out how many Carly sold:-
90 ÷ 2 = 45
Carly sold 45 rolls
