    A boat left a dock and sailed 16 miles north and then sailed 16 miles east, as shown in the diagram at the right. Which of the following is a true statement about the shortest distance the boat must sail to return to the dock?  - ProProfs

    A boat left a dock and sailed 16 miles north and then sailed 16 miles east, as shown in the diagram at the right. Which of the following is a true statement about the shortest distance the boat must sail to return to the dock? 

    • The shortest distance back to the dock is 16 miles.

    • The shortest distance back to the dock is between 21 and 22 miles.

    • The shortest distance back to the dock is between 22 and 23 miles.

    • The shortest distance back to the dock is approximately 32 miles.

    Correct Answer
    A. The shortest distance back to the dock is between 22 and 23 miles.
    Explanation
    The boat sailed 16 miles north and then 16 miles east, forming a right triangle. The shortest distance back to the dock can be found using the Pythagorean theorem, which states that the square of the hypotenuse (the shortest distance) is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is the shortest distance back to the dock, and the two sides are 16 miles each. Using the theorem, we can calculate that the square of the hypotenuse is 16^2 + 16^2 = 512. Taking the square root of 512 gives us approximately 22.63 miles, which falls within the range of 22 and 23 miles. Therefore, the correct answer is that the shortest distance back to the dock is between 22 and 23 miles.

    A television screen is described in terms of the diagonal measure of its screen.  If a TV screen is 20 inches wide and 15 inches high, what is the length of its diagonal?

    • 5.9 inches

    • 13.2 inches

    • 25 inches

    • 625 inches

    Correct Answer
    A. 25 inches
    Explanation
    The length of the diagonal of a rectangle can be found using the Pythagorean theorem. In this case, the width is 20 inches and the height is 15 inches. Using the theorem, we can calculate the diagonal as follows: diagonal = √(width^2 + height^2) = √(20^2 + 15^2) = √(400 + 225) = √625 = 25 inches. Therefore, the correct answer is 25 inches.

    Kari lives 5 miles due east of Jack, and Ryan lives 8 miles due north of Kari.  What is the approximate distance from Jack’s house to Ryan’s house?

    • 6.2 miles

    • 9.4 miles

    • 8.9 miles

    • 13.1

    Correct Answer
    A. 9.4 miles
    Explanation
    Kari lives 5 miles due east of Jack, and Ryan lives 8 miles due north of Kari. To find the approximate distance from Jack's house to Ryan's house, we can use the Pythagorean theorem. The distance between Jack and Kari can be considered as the base of a right triangle, and the distance between Kari and Ryan can be considered as the height of the right triangle. By using the Pythagorean theorem, we can calculate the hypotenuse, which represents the approximate distance from Jack's house to Ryan's house. The calculation is √(5^2 + 8^2) = √(25 + 64) = √89 ≈ 9.4 miles.

    Pat is sewing a rectangular tablecloth for her dining room table.  The tablecloth measures 90 cm by 180 cm.  She wants to sew a piece of decorative ribbon along both diagonals of the tablecloth. About how much ribbon will she need? - ProProfs

    Pat is sewing a rectangular tablecloth for her dining room table.  The tablecloth measures 90 cm by 180 cm.  She wants to sew a piece of decorative ribbon along both diagonals of the tablecloth. About how much ribbon will she need?

    • About 201 cm

    • About 402 cm

    • About 270 cm

    • About 540 cm

    Correct Answer
    A. About 402 cm
    Explanation
    To find out how much ribbon Pat will need, we can calculate the length of both diagonals of the tablecloth. The length of a diagonal can be found using the Pythagorean theorem, which states that the square of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides. In this case, the diagonal is the hypotenuse, and the sides are the length and width of the tablecloth. By applying the theorem, we find that the length of each diagonal is approximately 201 cm. Since Pat wants to sew ribbon along both diagonals, she will need a total of approximately 402 cm of ribbon.
