Answer:
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%.
Answer:
Depending on the passage, it means to find fault with someone, or to scold.
Answer:
nucleus
Explanation:
The nucleus is a membrane-enclosed organelle found in most eukaryotic cells. The nucleus is the largest organelle in the cell and contains most of the cell's genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it makes up just a small percentage of the cell’s overall DNA content)
