Ablue rope is three times as long as a red rope. a green rope is 5 times as long as the bike rope. if the total length of the three ropes is 508.25 meters, what is the length of the blue rope?

80.25

Step-by-step explanation:

B=3R

G=5B=15R

R+3R+15R=508.25

19R=508.25

R=26.75

3(26.75)=80.25

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

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
