Answer:
The fraction of tiles that will be the color of "sand" is 23/60
Step-by-step explanation:
we know that
The sum of the fractions of the tiles must be equal to 1
Let
x ----> the fraction of tiles that will be the color of "sand"
we have that

solve for x
Find the Least Common Multiple of denominators

Multiply both sides by 60

simplify


therefore
The fraction of tiles that will be the color of "sand" is 23/60

Answer:
is that 14 or 1/4?
Step-by-step explanation:
 
        
             
        
        
        
There are 25 boxes and 15 of them are shaded.
15/25 = 0.6 = 60%
 
        
                    
             
        
        
        
Given:
May:
hamburger: 3.2 pounds * 4.25 = 13.60
hotdogs:     3 packages * 4      = 12
Total cost: 13.60 + 12 = 25.60
June:
hamburger: 3.2 pounds * 1 1/2 = 4.8 pounds * 4.25 = 20.4
hotdogs:      3 packages * 1/3    = 1 package * 4        =   4
Total cost: 20.4 + 4 = 24.4
25.60 - 24.40 = 1.20
They spent more on May by $1.20. Choice C.

Hello 
cos ( x + pi/2) =cos(x)cos(pi/2)-sin(x) sin(pi/2) 
                       = cos(x)×0-sin(x) ×1
                    cos ( x + pi/2)   = - sin(x)
