I need help /

miles = 7920 feet

2 miles = 13200 feet

3 miles = 18480 feet

4 miles = 23760 feet

5 miles = 29040 feet

6 miles = 34320 feet

Explanation:

1 mile = 5280 feet

miles = 2640 feet

to convert miles into feet, multiply the whole numbers by 5280 and add 2640 to find your overall feet

2 : 2 x 5280 + 2640 = 13200 ft

3 : 3 x 5280 + 2640 = 18480 ft

4 : 4 x 5280 + 2640 = 23760 ft

5 : 5 x 5280 + 2640 = 29040 ft

6 : 6 x 5280 + 2640 = 34320 ft

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

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
