Answer:
Step-by-step explanation:
To simplify to a improper fraction, you do 243 times 5, which is 1215, then add 1, which is 1216
 
        
             
        
        
        
Answer:
64 meters squared and 6400 centimeters squared 
Step-by-step explanation:
Hope this helped. First do 8*8 for square meters then do 64 * 100 to get 6400 centimeters squared. 
 
        
             
        
        
        
Solución 1: 2(x) + 3(y) = 80 
solución 2: 3(x) + 2(y) = 70
3(y) + 2(x) = 80
2(y) + 3(x) = 70 
2y = -3x + 70 
y = -3x÷2 + 35
2x + 3(-3x÷ 2+35) = 80   
 -5x÷2 = -25   
-5x = -50
5x = 50    
 x-intercept: 10  
 x = 10  
 y = -3x÷ 2+35
  y = -(3÷2)(10)+35 = 20  
x-interpcet: 10 
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480
-8y + x = 0
4y + x = 480
x-intercept (solución 2)
x = -4x + 480
x-intercept (solución 1) 
4y + 180 - 8y = 0
 -12y = 480
y-intercept: 40
x-intercept: 320

Answer:
   b = 18
Step-by-step explanation:
From an external point, the products of distances to the near circle intercept and the far circle intercept are the same. For a tangent, such as AC, point A is both the near and far intercept point, so that product is the square of the length of AC.
   (AC)² = (CG)(CV)
   b² = 12·27 = 324 . . . . substitute known values
   b = √324 . . . . . . . . . . take the square root
   b = 18
