Ken earned $128 from his part time job this summer he spent 25% of his money on games he is going to donate 1/6 of the remaining money to charity how much money will the charity recieve

Answer -

5.3(repeated)

Step-by-step -

First you want to take the starting amount and multiply it by .25 which represents the 25%

The next step is to then divide the number you get by six giving one sixth of the 25%

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
