Question

Taylor uses tape to mark a square play area in the basement for her daughter. The area measures 28 sq.ft . Is the side length of the square rational or irrational ? Explain.

hintHint:

Use the formula for area of square

The correct answer is: Use the formula for area of square


    Complete step by step solution:
     
    Here, we have an area of play area = 28 sq ft.

    Formula for area of square =a2 , where a is the side length.
    not stretchy rightwards double arrow a squared equals 28


    not stretchy rightwards double arrow a equals square root of 28, which is an irrational number.

    So we get the side length of the square to be irrational.

    A Basketball coach is considering three players for most valuable player . The table shows the proportion of shots each player made of the shots they attempted.


    a) For a technical foul , the team can pick any player they want to shoot the free throw. Which player should the team pick ?
    b) Which player is most successful with their field goal shots? Explain.
    c) Rank the players by the percentage of the 3- point shots each made .
    d) If all the players attempted the same number of shots , which player would you choose as the most valuable player? Justify your answer.

    In this question, it can be explained further:
    A. Kimberly: 0.857 > 4/5 > 71%
    Here, Kimberly's free throws have the highest proportion.
    B. Martin: 49.5% > 9/20 > 0.448
    Here, Martin's proportion of field goals is the highest.
    C. Corey: 0.338 > 1/3 > 32%
    Kimberly > Corey > Martin
    From the above explanation, we can conclude Kimberly is first, Corey is second, and Martin is third.
    I'd go with Kimberly because he has a higher percentage on all shots than the other two players.
