Because it is like having a unit of measurement that is set
lets say that in a certain country, one serving of bread is 1/2 of the standard loaf
and if you have 3 servings, you have 3/2 loaf so the bottom number tells you how many parts out of 1 whole you have
        
             
        
        
        
Answer:
The volume of a cone is:
V=(hπr^2)/3, where h=height and r=radius  
V=(7π4^2)/3
V=112π/3 ft^3
V≈117.29 ft^3  (to nearest hundredth of a cubic foot)
Step-by-step explanation:
 
        
             
        
        
        
The number of decorative pillows did the realtor arrange on each twin bed and queen bed is 6 and 9 respectively.
<h3>Simultaneous equation</h3>
let
- Number of decorative pillows for twin bed = x
- Number of decorative pillows for queen bed = y
x + y = 15
2x + y = 21
From equation (1)
x = 15 - y
- Substitute x = 15 - y into (2)
2x + y = 21
2(15 - y) + y = 21
30 - 2y + y = 21
- 2y + y = 21 - 30
-y = -9
y = 9
Substitute y = 9 into
x + y = 15
x + 9 = 15
x = 15 - 9
x = 6
