Answer:

  • 240.73 mm

Step-by-step explanation:

The hour hand is 20 mm and the minute hand is

  • 200% of 20 mm = 2*20 mm = 40 mm long

The tip of the hour hand travels 1/12 of the circle and the tip of the minute hand travels full circle in one hour.

Find each length and their difference using circumference formula.

  • C = 2πr

<u>Hour hand</u>

  • 1/12*(2*3.14*20) = 10.47 mm (rounded)

<u>Minute hand</u>

  • 2*3.14*40 = 251.2 mm

<u>The difference between the two above</u>

  • 251.2 - 10.47 = 240.73 mm

Answer:

We conclude that the percent of decrease = 20%

Step-by-step explanation:

Given

  • Original amount = $3930
  • Amount of decrease = $3930 - $3144 = $786

Using the formula

Percent of decrease = ( amount of decrease / orignal amount × 100 ) %

                                   = ( 786 / 3930 × 100 ) %

                                    = ( 0.2 × 100 ) %

                                    = 20%

Therefore, we conclude that the percent of decrease = 20%
