An archery target consists of a gold circle with radius of 5 inches surrounded by a red ring whose diameter is 20 inches. Next, there are three progressively larger rings – blue, black, and white. The diameter of each ring is 10 inches larger than the diameter of the previous ring. John is a beginner so his aim is poor and, if his arrow hits the target, its location on the target is completely at random. John shoots and then yells, “I hit it!” Without using your calculator, find the following probabilities. Write the answers as a percentage. a) The probability his arrow landed in the gold circle is ______. b) The probability his arrow landed in the white area is ______. c) The probability his arrow landed in the red or the blue area is ______.

Yolanda has a new aquarium. The tank is in the shape of a rectangular prism,84in long, 36in wide, and 48in deep. She plans to raise fish and sell them to a local pet store. The pet store will inspect the aquarium to make sure that the fish are being kept in a healthful environment. One of the main concerns is that each fish has enough water. Yolanda looks up the amount of water needed for the species of fish she plans to raise. She finds the answer, but it is given in cubic feet. (a) Find the volume of water that the tank holds in cubic feet. Use the table of conversion facts, as needed. ft3 (b) The particular species Yolanda plans to raise requires at least 1.1ft3 of water per fish. If there is any amount less than this, no matter how much less, the pet store will not accept Yolanda's fish. What is the largest whole number of fish that she can keep in the aquarium? # fish (c) The pet store will pay $3.49 for each fish. If she fully populates her…

Darnell and Jake are playing a game they made up which includes throwing darts at this target. The point values for each region of the target are shown. The radius of the 50-point region is 3 inches. The width of each of the other regions is 4 inches. 5 concentric circles where each circle contains values from 10, 20, 30, 40 and 50. Darnell and Jake are currently tied in their game, and Jake has to choose one of these options: Option 1: He can accept the tie, and the game is over. Option 2: He can make one more throw. Jake wins if he earns at least 30 points on the throw, but he loses if he earns less than 30 points. Complete each part of this task to determine which option Jake should choose. Part A Describe the process you could use to find the probability that Jake will earn at least 30 points on a throw, given that he hits the target? Note: Assume that it is equally likely that he will hit any region in the target.

The game of baseball darts is played on a square board marked like a baseball diamond. Each side of the diamond is 15 inches long. The bases are 3.5 inch squares in each corner. There is a home-run circle in the center with a diameter of 2 inches. “Hits” are made by landing on the bases or in the home-run circle. Landing anywhere else in the diamond is considered an “out”. Mona is blindfolded and throws a dart which lands on the board in a random manner. What is the probability that she is “out”?
