Answer:
5 hamburger packages and 6 bun packages
Step-by-step explanation:
It is asking for the highest common multiple of 12 and 10. the first time a multiple of 12 is divisible by 10 is at 12x5, which is 60. now divide 60 by 12 and 10, 5 and 6.
 
        
             
        
        
        
Answer:
91.99%
Step-by-step explanation:
To find what percentage of $7599 is $6990, we simply need to divide $7599 by $6990 and multiply by 100:
6990 / 7599 * 100 = 91.99%
Therefore, they paid 91.99% of the original price.
 
        
             
        
        
        
Answer:
Water needed for pool = 486 cubic feet
Plastic liner required for the pool = 298.3 feet
Step-by-step explanation:
Top view of the pool is a composite figure, having one rectangle and a trapezoid.
1). Water needed for the pool = volume of the pool
Volume of the pool = Area of the base × Depth 
                                = (Area of the rectangle + Area of the trapezoid)× depth   
Area of the trapezoid = 
                                     = 
                                     = 105 ft²
Area of the rectangle = Length × width
                                     = 11 × 1.5
                                     = 16.5 ft²
Now, volume of the pool = (105 + 16.5) × 4
                                           = 121.5 × 4
                                           = 486 cubic feet
b). Liner required = surface area of the pool excluding top
                              = Surface area of the walls + Area of the pool base
                              = (Perimeter of the pool) × depth + area of the base
                              = (12 + 11 + 1.5 + 10.7 + 9)×4 + 121.5
                              = 176.8 + 121.5 
                              = 298.3 square feet
Therefore, amount of water required = 486 cubic feet
liner needed = 298.3 square feet
