Okay I’m doing a quiz right now and I do not know what tooo dooo So Tyler asked for a fish tank for his birthday the tank he wants is a rectangular prism 20 inches long 10 inches wide and 12 inches tall (20 x 10 x 12)
How much water will the fish tank hold in inches cubed?

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

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
