How much money did you have at 25? What was your life like?
Posted by GeneralDodo on 3/13/21 at 4:18 pm
Was watching CNBC and they said this was the age where the average American starts to save money, pay for all the bills without their parents support.
I had around $11,000 living in Dallas.
This might be pocket change to the rest of the OT.

What did he do policy wise?
How did Edwin Edwards beat Dave Treen so bad in the 1983 governors race?

Edwards got 63% of the vote. What did Dave Treen do wrong?
If Derek Chauvin is found not guilty will the riot be worse than Ferguson or the LA Riots?
Posted by GeneralDodo on 3/8/21 at 6:23 pm
Looks like Derek Chauvin's lawyers only have to convince the jury of "reasonable doubt that it could have been an overdose" which well when the County's Coroner Report says "No life-threatening injuries identified" and the toxicology report has a bunch of drugs listed including Fentanyl & methamphetamines.
Things might get ugly.

re: Mathematicians, your help is needed

I dropped out of high school my junior year but I scored a 29 on the ACT for the math section.
You already have the lenghts of all sides, you just have to sum them up. You have 8 times the side of the pointy bits, and 4 times the side of the octagon, so that would be 8*7.28cm + 4*4cm = 74,24cm
Now the area is a bit harder. The trick is to divide the area into easier shapes until you have a shape with an area you know the formula of. You have to find the area of the octagon and the area of the triangles on the sides. Let's begin by the easiest, the triangles.
You can use the general formula of the area of a triangle, base*height/2. On the left triangle you have the height (7cm), and the base is a side of the octagon. All sides of the octagon are the same lenght, 4cm. So one side triangle has an area of 4*7/2 = 14cm².
Finally the hardest part, the octagon. This time we have to devide it further. The idea is to sketch all the lines similar to the 9,7cm and the 2,8cm ones. You should have a kind of tic-tac-toe with the corners missing. From there you can calculate the areas of the 4 corner triangles (right-angled triangles, so (side1*side2)/2 using the side forming the right angle). You have the area of the central square which has a side of 4cm. And finally you have 4 rectangles on the sides, with one side of lenght 2.8 and one the same lenght as the square. Then you sum all theses areas to get the area of the octagon. I find 78,48cm².
Finally you sum the area of the octagon and of the 4 side triangles, and... bam.
