circular washer. Units are mm. 19. What fraction of the circular piece of (40) metal was removed when the hole was made? 20. When the washer is bolted into place, (40, 72) what is the area of the washer that is pressed against the object to which it is bolted? Use 3.14 for T. Express your answer in square millimeters and again in square centimeters. *21. The cone in problem 23 has a slant (Inv. 2, 95) height of 20 cm and a circular base with a radius of 5 cm. Use the Pythagorean Theorem to find the height of the cone. If a calculator is available, find the height to the nearest tenth of a 201 centimeter. 5.

A collector purchased a rare coin for $100. After the purchase, the coin’s value increased by 10.25% per year for the first x years and 5% per year for the next y years. The expression 1.1025 x ⋅ 1.05y when multiplied by 100, reveals the value of the coin, in dollars, (x+y) years after the coin was purchased. The collector simplified the expression to 1.05x+2y, but he made a mistake. How can the collector correct his mistake? The base of the simplified expression should be (1.05, 1.1025), and the exponent should be (2xy, x+y, x+2y, 2x+y, 2x+2y). choose one for each
