Answer:
hello :
90 = 15×6
75 =  15× 5 
highest common factor of 90 and is 15 because highest common factor of 5 and 6 is 1
90 = 3² ×2×5
75= 5^3
common multiple of 90 and 75 is : 3²×2×5²  = 450
90 and 75  both smaller than 100.
 
        
             
        
        
        
Answer:
So, the relation between variables are

Step-by-step explanation:
We are given 

Since, we have to find relation between variables
so, we can solve for y 

Firstly, we will multiply both sides by y

we can simplify it 

we can isolate y
so, we can divide both sides by 7
so, we get 

 
        
             
        
        
        
Think of the two pieces together as a single cone of height 19, and its volume.
Then think of only the upper piece as a cone, and find its volume.
The volume of the frustum is the total volume minus the volume of the upper piece.
The volume of a cone is:

Total volume:

Volume of upper cone:

Volume of frustum:

Let length of  the hypotenuse = 3x and length of given leg be x feet.
then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81
so x = 9 and 3x = 27
Hypotenuse is 27 feet and the leg equals 9 feet.
