Answer 1

90% of people marry there 7th grade love. since u have read this, u will be told good news 2night. if u don't pass this on nine comments ur worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of ur life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you...

The answer is 8 so its a direct proportion

I think...

Answer 2

The constant of Proportionality is 8.

What is constant of Proportionality?

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Mrs. Thomas was on vacation out of state when she stepped off a curve and injured her left ankle. Due to severe pain she was seen at an urgent care center where she underwent a left ankle x-ray, which was negative. She was diagnosed with a left sprained ankle. A walking boot was provided to stabilize and protect her left ankle. She was provided with appropriate discharge instructions and instructed to follow up with her primary care physician upon returning home. When she presented her BlueCross BlueShield insurance card at check out, Mrs. Thomas was informed that the physician who provided treatment is a nonparticipating provider (nonPAR) and that the urgent care center accepts credit cards for payment in full. The total due was $1,500, and Mrs. Thomas assured the office staff that her insurance company would reimburse the urgent care center for services provided. The office staff further explained that their providers had not signed a contract with her insurance, and thus Mrs. Thomas was required to settle the bill upon discharge.
