    The International Basketball Federation specifies that for a new basketball to be “certified”, it must bounce back at least 0.722 times the height from which it was dropped.  If a ball is dropped from a height of 70.9 in, which of the following is a correct calculation for how high it must bounce to be certified?

    • 70.9 x 0.722 = 51.1898 inches

    • 70.9 x 0.722 = 51189.8 inches

    • 70.9 ÷ 0.722 = 981.994 inches

    • 70.9 ÷ 0.722 = 98.1994 inches

    Correct Answer
    A. 70.9 x 0.722 = 51.1898 inches
    Explanation
    The correct calculation for how high the ball must bounce to be certified is 70.9 x 0.722 = 51.1898 inches. This calculation follows the specified requirement from the International Basketball Federation that the ball must bounce back at least 0.722 times the height from which it was dropped.

    A board that is 96 inches long is to be cut into pieces that are 10.5 inches long.  Which of the following is a correct calculation for how many boards 10.5 inch boards can be cut from the 96-inch board?

    • 96 x 10.5 = 100.8, so 100 boards

    • 96 x 10.5 = 10.08, so 10 boards

    • 96 ÷ 10.5 = 9.143, so 9 boards

    • 96 ÷ 10.5 = 0.9143, so almost 1 board

    Correct Answer
    A. 96 ÷ 10.5 = 9.143, so 9 boards
    Explanation
    The correct calculation for how many boards can be cut from the 96-inch board is 96 ÷ 10.5 = 9.143, so 9 boards. This calculation involves dividing the length of the board (96 inches) by the length of each piece (10.5 inches) to determine how many complete pieces can be obtained. In this case, it is determined that 9 complete boards can be cut from the 96-inch board.

    One cubic foot of water weighs about 62.4 pounds.  If a plastic kiddie pool can hold 6.15 cubic feet of water, which of the following is a correct equation for the weight of the water when the pool is full?

    • 62.4 x 6.15 = 38.376 pounds

    • 62.4 x 6.15 = 383.76 pounds

    • 62.4 ÷ 6.15 = 10.15 pounds

    • 62.4 ÷ 6.15 = 101.5 pounds

    Correct Answer
    A. 62.4 x 6.15 = 38.376 pounds
    Explanation
    The correct equation for the weight of the water when the pool is full is 62.4 x 6.15 = 38.376 pounds. This equation calculates the weight of one cubic foot of water (62.4 pounds) multiplied by the volume of water the pool can hold (6.15 cubic feet), resulting in the total weight of the water in the pool.
