Answer:
3:1 
54:18
Step-by-step explanation:
You can divide both sides by 9 to get one ratio:
27/9:9/9
3:1
You can also multiply both sides by 2 to get another ratio:
27(2):9(2)
54:18
 
        
             
        
        
        
Answer:
Circular paraboloid
Step-by-step explanation:
Given ,

Here, these are the respective  axes components.
 axes components.
- <em>Component along x axis  </em> </em>
- <em>Component along y axis  </em> </em>
- <em>Component along z axis  </em> </em>
We see that , from the parameterised equation , 
This can also be written as :

This is similar to an equation of a parabola in 1 Dimension.
By fixing the value of z=0,
<u><em>We get  which is equation of a parabola curving towards the positive infinity of y-axis and in the x-y plane.</em></u>
 which is equation of a parabola curving towards the positive infinity of y-axis and in the x-y plane.</em></u>
By fixing the value of x=0,
<u><em>We get  which is equation of a parabola curving towards positive infinity of y-axis and in the y-z plane. </em></u>
 which is equation of a parabola curving towards positive infinity of y-axis and in the y-z plane. </em></u>
Thus by fixing the values of x and z alternatively ,  we get a <u>CIRCULAR PARABOLOID. </u>
 
        
             
        
        
        
Answer:
The percentage change of vacationers is 33.3 %
Step-by-step explanation:
Given as :
The old value of the vacationers = $ 1500
The new value of the vacationers = $ 2000
Let the percentage variation = x %
Or, x % increase =  × 100
 × 100
Or,  x % increase =  × 100
 × 100
Or, x % increase =  × 100
 × 100
Or, x % increase =  × 100
 × 100
Or, x % increase = 
∴  x  = 33.3 %
So, The percentage increase change is 33.3 %
Hence The percentage change of vacationers is 33.3 %   Answer
