Answer:
10200
Step-by-step explanation:
This is an example of a compound interest. The equation for this problem is 10000*(1+2/100)^n. The n is the year as 1999 is 1 year away from 1998, you just replace n with 1 and you have a simple equation.
 
        
             
        
        
        
First find the perimeter of the rectangle: 2w+2l which is 8+28=36. Then find the square root of 36 which is 6 so that is the answer.
        
                    
             
        
        
        
{ x + 4y = 22     ( + x - x = 0 )
{ - x + 5y = 23
4y + 5y = 22 + 23
9y = 45
  y =<u> 45 </u>
         9
  y = 5
x + 4y = 22
x + 4 . 5 = 22
x + 20 = 22
x = 22 - 20
x = 2
S = { 2 , 5 }

Answer:
x = 30
y = 15
Step-by-step explanation:
<u><em>All the angles are </em></u><u><em>90°</em></u><u><em>, so set 6y and 3x equal to 90, like so:</em></u>
6y = 90
<u><em>Divide both sides by 6:</em></u>
y = 15
<u>Solving for x:</u>
3x = 90
<em><u>Divide both sides by 3:</u></em>
x = 30
