today in history

we learned all about WWI. We went over all of the causes and reasons why this world war occured. we learned how it all turned into a huge dumb fight.

today in math...

The formula for the length OP or p is a kind of 3 dimensional form of Pythagoras' theorem.Here's how the working would go if we had a = 4 and b = 3 and c = 12.

Here's how the working would go if we had a = 4 and b = 3 and c = 12.Using Pythagoras' theorem in the yellow right-angled triangle we get
OQ = the square root of (16 + 9) = 5 and then, using Pythagoras' theorem in the vertical green right-angled triangle, we get
OP = the square root of (25 + 144) = 13.
Alternatively, in just one step of working, we have
OP = the square root of (16 + 9 + 144) = 13.

Blonde paint job
A blonde, wanting to earn some money, decided to hire herself out as a handyman-type and started canvassing a wealthy neighborhood. She went to the front door of the first house and asked the owner if he had any jobs for her to do."Well, you can paint my porch. How much will you charge?"The blonde said, "How about 50 dollars?" The man agreed and told her that the paint and ladders that she might need were in the garage. The man's wife, inside the house, heard the conversation and said to her husband, "Does she realize that the porch goes all the way around the house?"The man replied, "She should. She was standing on the porch."A short time later, the blonde came to the door to collect her money."You're finished already?" he asked. "Yes," the blonde answered, "and I had paint left over, so I gave it two coats. "Impressed, the man reached in his pocket for the $50. "And by the way," the blonde added, "that's not a Porch, it's a Ferrari."
