If akayla painted 1/3 of a wall in 20 minutes how long will it take her to paint 4 walls

240 minute or 4 hours

Step-by-step explanation:

We can use a ratio to solve

1/3 wall           4 walls

 =

20 minutes      x minutes

Using cross products

1/3 x = 20 *4

1/3 x = 80

Multiple each side by 3

1/3 x* 3 = 80*3

x = 240 minutes

Divide each side by 60 to change to hours

x = 240/60

x = 4 hours

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
