The designer must sell 200 hats for breaking even. 
Step-by-step explanation:
Given, 
Cost for material for each hat = $5.50 
Selling price of each hat = $12.50 
Cost spend on advertising = $1400
Let, 
x represents the number of hats.
Revenue = 12.50x
Costs = 5.50x+1400
For breaking even, 
Revenue = Cost 

Dividing both sides by 7 

The designer must sell 200 hats for breaking even.

Answer:
34) 75
35) 60 
36) 210
Step-by-step explanation:
34) Area of a rectangle: 
L x B 
 = 15 x 5 
 = 75
35) Area of a trapezium : 
½ h (sum of || sides)
  = ½ x 6 x (12+8)
 = 3 x 20
 = 60
36) Area of a regular hexagon:
3BH
 = 3 x 7 x 10
 210

The mean sustained wind velocity has the equation:
v = 6.3 √(1013 - p)
If we are given with the mean sustained wind velocity of 64 m/s, then we can solve for the air pressure using the equation:
64 = 6.3 √(1013 - p)
64/6.3 = √(1013 - p)
10.1587² = 1013 - p
p = 910 millibars
hope this helps!!!!!!!!!!!!
 
        
                    
             
        
        
        
The answer is 3x-3. You have to distribute the 3 to both of the variables in the equations. The 1 in the parentheses is a negative and multiplying the 3 will result in a negative 3.
