Answer:  For every 1 can of red paint, the number of yellow paints used by the painter is  and
 and
There are approximately 29 cans of yellow paints for 34 cans of red paints.
Step-by-step explanation:
Since we have given that 
Number of cans of red paint = 14
Number of cans of yellow paint = 12
According to question, we have to find that for every 1 can of red paint the painter uses what number of yellow paints;
Since the ratio of red paint to yellow paint is given by

So, for every 1 can of red paint, the number of yellow paints used by the painter is 
Similarly,
If Number of can of red paint is used = 34
So, Number of cans of yellow paint will be 

Hence, there are approximately 29 cans of yellow paints for 34 cans of red paints.
 
        
             
        
        
        
Answer:
Let x = the third side
  
In a triangle, the sum of any 2 sides must be larger than the third side.
I believe this is called the triangle inequality theorem.
  
We can construct 3 inequalities to obtain the range of values for the third side.
  
   (Inequality #1)   12 + 4 > x
                                   16 > x
  
   (Inequality#2)    12 + x > 4
                                     x > -8   (we can discard this ... we know all sides will be positive)
  
   (Inequality #3)   4 + x > 12
                                    x > 8
  
So when we combine these together,  
  
    8 < x < 16
  
X (the third side) must be a number between 8 and 16. but not including 8 and 16 
 
        
             
        
        
        
The whole numbers add up to 100. So now we are left with 1/2 or 0.5, 3/5 or .60, and 1/8 or .125. Those add up to 1.225 so the amount of sand in pounds in the wheelbarrow is 101.225. Hope I helped! If you have any questions just leave a comment.
