Imagine you’re alone in a boat with a large hole in the bottom. Sharks are swimming around you on all sides and the boat is sinking fast. How do you survive?
Yes, because a plane’s wheels roll freely and have no affect on the movement of the plane(unlike a car). The propeller or jet engine makes the plane move and the plane will be able to take off normally. If you don’t believe me, here’s proof.
A bag contains 64 balls of eight different colors. There are eight of each color (including red). What is the smallest number you would have to pick, without looking, to be sure of selecting 3 red balls?
She will always need to give you 5 apples. You both need at least 5 apples to begin with, but apart from that it doesn’t matter exactly how many you each have. When she gives you 5 you will have 10 more than her because she will lose 5 and you will gain 5, resulting in a net difference of 10.
For example, if you each have 25 apples and she gives you 5 of hers, she will be left with 20 and you will now have 30, precisely 10 more than she has.
Ronald has a rare opportunity to meet the President of the United States. During his visit the president gives him a gift but tells Ronald he is never to sell it unless he sees the president again. Ronald consents, but the president dies later that year. Years later a man offers to buy the President’s gift for $1000. Ronald agrees and exchanges the gift for 20 crisp $50 bills. Did he keep his promise?
Yes. The president was Ulysses S. Grant, who died in 1885 and whose face has been on the $50 bill since 1913. He saw the president on the bills before he made the exchange.
