10.5 is a rational number because it is a number that can be turned into a fraction.
10.5 = 10 1/2 = 21/2
        
                    
             
        
        
        
<span>Y varies jointly with w and x, inversely with z
this means that
</span>y ∝ wx / z
in equation form
y = kwx / z
where k is the proportionality constant
360 = k ( 8 ) ( 15 ) / 3
k = (360) ( 3) / ( 8 ) ( 15 )
k = 9
so the eqution is
y = 9wx / z
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
In any 30-60-90 triangle, the side lengths are in the ratio  , where
, where  is the hypotenuse, or longest side, of the triangle and
 is the hypotenuse, or longest side, of the triangle and  is the side opposite to the 30 degree angle.
 is the side opposite to the 30 degree angle.
In the given 30-60-90 triangle, the longest side (hypotenuse) is marked as 24. Since  is opposite to the 30 degree angle,
 is opposite to the 30 degree angle, 
Therefore, we have:

Based on our side length ratio  ,
,  is then:
 is then:
