The next hole has a windmill as shown below. Gerald decides that he is never going to be able to time his shot right, so he decides to just randomly swing and hope that the ball makes it past the blades. If the end of each blade is 6 inches and the distance from the center of the fan to the end of a blade is 3 feet, what is the probability of Gerald's shot making it past the windmill? Express your answer as a percent to the nearest tenth.

86.7%.

Explanation:

Considering the diagram, the path of the tip of the blades is a circle.

Hence, determine the circumference of the circle.

C = 2πr = 2π * 3 ft = 6π ft.

Then determine how long the blade edges are all together.

6 in * 5 blades = 30 inches

Therefore, to determine the fraction of the circumference of 30 inches, convert circumference to inches

6π ft * (12 in ÷ 1 ft) = 72π in.

Hence, the probability of Gerald’s randomly timed shot hitting a blade of the windmill

=> 30 ÷ 72π

=> 30 ÷ [72 * (22/7)]

= 13.3%.

Finally, the probability of his shot getting past the blades is then 100 – 13.3 = 86.7%.

your answer shall be,

a. it comes from the word rebirth.

many were disgusted, nauseated and shook their heads with disapproval upon finding out about the recycling of water process. however, they do not seem to understand that this process actually saves water.

although individuals may argue that it is unhealthy, and or unsafe to drink water that is "from toilet to tap" , the water is 100% safe to drink and involves forcing the water across a membrane, which "removes   any impurities, including viruses, pharmaceuticals and dissolved minerals" , according to paul rozin, a psychology professor who studies revulsion.

i agree that that the thought of drinking water that once ran through someones kitchen sink isn't quite appealing, but recycled wastewater is safe to drink. it also saves water. "the city produces nine million gallons a day" claims russell schreiber, the city’s director of public works.

recycled waste water has absolutely no health concerns whatsoever. when wastewater goes into a system, it's absorbed back into the ground. thus, it goes into a sewer system, then goes through a treatment process that removes contaminants before being released. nonetheless, there is no problem in drinking water that has been recycled.

"in drought-ed california, there are six state agencies that use wastewater that comes from an intellectual property source," according to the university of california, riverside. studies show that this water is completely safe to drink, however, it still doesn't mean people are going to happily pour it in a water glass.

researchers hope it "may make consumers more amenable to drinking recycled wastewater," extraordinarily, women who have a higher "disgust reaction" and make most consumer purchasing decisions.
