If state has 1627260 people and 1490 square miles, then we divide the number of people by the area and we get the density per square mile.
1627260 / 1490 = 1092,120805369128
After rounding it to the nearest whole number we get 1092.
The answer: In such a state 1092 people live in a square mile.
        
             
        
        
        
Answer:
sum of products expression = x₁x₂x₃'  +  x₁x₂'x₄  + x₁x₂x₄
Step-by-step explanation:
Given function ( f ) = x₁x₂'x₃'  +  x₁x₂x₄ + x₁x₂'x₃x₄'
using algebraic manipulation 
f = x₁ [ x₂'x₃'  +  x₂x₄ + x₂'x₃x₄' ]
  =  x₁ [ x₂'( x₃' + x₃x₄') +  x₂x₄  ]
next apply Boolean rules 
a + bc = ( a + b )(a + c ) 
a' + a =1 
hence 
minimum sum-of-products expression = x₁x₂x₃'  +  x₁x₂'x₄  + x₁x₂x₄
 
        
             
        
        
        
You mean '39 is what percent of 12.5 ?'
So, the answer is 
39/12.5 × 100
= 3.12 × 100 
= 312% 
So, 39 is 312% of 12.5.
(The percentage is greater because 39 is greater than 12.5)
        
             
        
        
        
Answer: 3 054 in^2
Step-by-step explanation:
 
Sphere volume formula = 4/3 pi r^3
So... 4/3 pi 9^3
= 3 053.63 in^2
