Apply the Pythagorean theorem
a^2 + b^2 = c^2
a = 5, b = 13.
5^2 = 25, 13^2 = 169
25 + 169 = 194
square root 194 = 13.928, rounded to nearest foot = 14 ft. 
The minimum ladder length required to reach the top of the wall = 14 ft.   
 
        
        
        
Answer:
(A) 33.9 (B) 22.6
Step-by-step explanation:
We first need to round to the nearest dollar for both prices. Lets examine both numbers.
$30.<u>1</u>2       $19.<u>9</u>3
We can round $30.12 to $30 since the number in the tenths place is 1 and we can round $19.93 to $20 since there is a nine in the tenths place.
Now we must find the tax for each number. We can do that by multiplying each number by 0.13 since that is 13% in decimal form. Lets do that now
 
           
Now we can find the final price for each number by adding the tax to the rounded price.
 
          
Hence, (A) 33.9, (B) 22.6
 
        
             
        
        
        
<span>Igual que el último. 
Si es "$ 2,000 por 100 sobres, dividiremos 2,000 / 100 y obtendremos 20, luego multiplicaremos 20 por 75 y obtendremos" $ 1500 ".
 
Esta es la ecuación
 $ 2,000 / 100 = 20 x 75 = $ 1,500
  
Espero que esto ayude :-)</span>
