a babysitter makes $7.50 per hour. is the relationship proportional? why or why not?

Yes, the relationship is proportional.

Step-by-step explanation:

The definition of a proportional relationship is when the ratios are constant. (It remains the same)

So, for every hour the babysitter makes 7.50, making the ratio of $/h 7.50/1.

For 2 hours, the ratio fo $/h would be 15/2.

15/2 simplifies to 7.50/1, so the ratio would be the same.

Therefore, the relationship is proportional.

Another easier way to find a proportional relationship is if there's no addition of subtraction in the equation. (If the babysitter starts off with a base rate then gets extra money every hour, it's not proportional).

Example: A babysitter is paid $5, then gets $2 for every hour.

The ratios of $/h would be 7/1 and 9/2, which aren't the same, making that not proportional.

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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
