You and a friend decide to race, but don’t set the rules beforehand. You pick a tree on the other side of a field to run towards. You think that you have to follow the fence around the edge of the field, while your friend runs straight for the tree. If you run 2000 feet north and then turn 90° and run 1250 feet east to get to the tree, while your friend runs diagonally across the field to the tree, how far (to the nearest 10th of a mile) does your friend run?

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

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

the answer is the third / last answer
