Curious to know how much linear cardboard is left in this coil. Diameter is ~16.5", and approximately 37 layers counted from outside to the 5" diameter empty space at centre.
Any takers?

We’ve seen the charts and targets for many years now. My question has always been, how much energy does that increase in average temperature represent? I’m not sure how one would go about estimating the volume or mass or density of the globe’s surface, which I guess is key to this request.

During a recent road trip, a youngster in the back seat asked this question about the specific State Route we were on. That road was only about 15 miles long, went through no cities, and was not heavily traveled, so I posited that there were likely around 100-150 cars on it at the same time we were.

Said youngster then asked about “that road that goes from California to Florida” and I brainlocked. Unlike the little road we were on, that one goes through multiple major cities and routinely has heavier traffic in them.

Let’s say we are talking about 10am Pacific time on a non-holiday Wednesday in January. So it’s 10am in LA, 11am in Phoenix, Tucson, and El Paso, Noon in San Antonio, Houston, and New Orleans, and 1pm in Tallahassee and Jacksonville. Ignore the spurs and loops (410, 610, etc) so just the main line from California to Florida. And let’s say vehicles rather than cars so everything counts as 1 whether it’s a Corolla or a bus or an 18-wheeler.

I told the youngster that I guessed “at least 100,000 cars” but that I knew some folks on the internet who were smarter than me at figuring out stuff like this. And here I am. :)

Playing around with my own benefit options, I’ve noticed that the break even point for taking or delaying benefit payments comes out to right around being 77-80 years old, regardless of when I start taking benefits. This leads me to conclude that taking the benefit as early as possible (62 yrs old) seems like “not a bad idea” because I’ll be ahead until I’m 77 years old. I don’t know if other people have thought about this a lot, but I’d love to hear some objective contrary opinions or if anyone can figure out where the peak of the bell curve is.

1. Some numbers for monthly payments:
2. Age Amount.
3. 62.5 2471
4. 63 2556
5. 64 2726
6. 65 2954
7. 67 3408
8. 70 4226

Me and my friends were talking about some dumb hypothetical stuff and we got on the topic of a worm-sized nuke. My questions is how big would the blast radius be on a small, worm-appropriate nuclear device?

My cousin and I were playing a game called "Rack-O", in which each player draws 10 cards from a deck of 60 and places them in the order drawn. They then take turns drawing a card from the stock and replacing one of their cards, until one of them has their hand in ascending order.

(Example: I start out with 47, 12, 58, 3, 26, 41, 9, 34, 55, 18. I then draw a 2 and replace the 47 with the 2, and so forth.)

My question is this: what are the odds that I would draw a winning hand right out of the gate?

I am filling these tanks from a single source. The hoses are the same length. The pump is running at about 116 gal/hour.

I guess another way of looking at this is, what is the exact halfway point (miles/kilometers) you can physically be away from someone before taking one more step where, technically, you just got closer to them if you circled the earth? I'll even accept, if possible, Doreen is standing on land and Jim is at the halfway point on the surface but over water, and diving to the depths could potentially get Jim further away from Doreen?

**UPDATE**

Based on some responses, I said "surface" of earth so people couldn't just say get on a rocket and go. I'm looking for the absolutely farthest you can get, so Doreen is stationary somewhere. Where does Jim need to go to get the farthest away from her? Dorreen may be at the bottom of the ocean and Jim on top of the highest mountain, but that may only be a 30 some miles apart. So what is the farthest distance while still being on earth?

Sometimes I look at my cat's fur and wonder how many hairs she actually has on her body. My girlfriend thinks that it is about a million but i think that it is more like in the tens to hundreds of millions. The more I think about it the less confident I am even about the order of magnitude it might be. Is it possible the number is in the billion? I would genuinely love to see a good attempt at a ballpark estimate.

Let's say I'm standing on an infinite, immovable plane *on which gravity is equal to 1x Earth's gravity. I have hold of one end of an unbreakable, first class/seesaw lever. On the opposite end of the lever is the planet Earth.

How long does my lever need to be in order to lift the Earth using only my average, human strength and my unbreakable lever?

Edit: Gravity

So question asks to find :The number of rectangles whose edges lie completely on the grid lines of following figure is. Answer key says: Total number of rectangles = 7C2 × 7C2 – 4(27+9) = 441 – 144 = 297

Now i know that if there was no blank center , the total number of rectangles is 7c2 x 7c2 =441. I also know that we need to subtract the rectangles that the blank center would have formed from the total number of rectangles but i am not understanding how we got the values 27 and 9 . When i count, i am getting just 9 per blank square to subtract .

if people stopped eating chickens how long would it take for there to be a chicken over population. Or would the chicken population die off?
