I call it the “Maple Leaf Loophole. It hits all my requirements for a practice activity: To prepare, you will need cards or slips of paper with problems on one side and the answers on the other. Here are some rational expressions cards to try out. It’s important to use problems that will take all your kids about the same amount of time to complete.

I’ve done a pretty good job of beating the smart people problems. Society puts smart people on quite a lofty pedestal but there’s some real downsides to being highly intelligent. You’re on this website because you were either born a smart person which as you will see by the end of this article is actually not such a lucky roll of the genetic dice or on your way to becoming a very smart person.

Whether you’re part of the club already or still like me! By the End of this Article You will understand some of the vexing problems that you have, up to this point in your life, failed to beat with your smarts and intellectual resources. For each problem we identify solutions; both actionable behaviors to change and deeper mindsets to internalize. Do you know anyone that when you talk to them you feel like a young Jedi getting advice advice from Yoda?

## Density and Specific Gravity – Practice Problems

By Noelle Devoe Jun 24, A math problem can often look super simple Then there are the problems that make you feel like a math whiz when you solve it in 2 seconds flat — only to find your answer is WAAAAY off. That’s why math problems go viral all the time, because they’re simultaneously easy and yet so not. Advertisement – Continue Reading Below Here are five problems that prove the point: What’s the Question Mark?

Let’s start off super simple.

· In the mathematical discipline of graph theory, a matching or independent edge set in a graph is a set of edges without common g a matching in a bipartite graph can be treated as a network flow tion · Properties · Matching polynomials · Characterizations and notes(graph_theory).

AP Biology – Carbon Dating examples, videos, experiments Carbon 14 dating math problems, recommended posts Liquid scintillation counting is another radiocarbon dating technique that was popular in the s. Carbon 14 Dating – Math Central The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. Older carbon dating techniques directly detected decays of C14 atoms. In particular, given a pure sample of C12, I suspect a mass spectrometer would indicate that a non-zero amount of C14 present.

Another possible avenue is C13, which has a small but non-zero neutron absorption cross section. This would have upset carbon 14 dating math problems ratio of carbon to carbon When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is —0.

## Can You Solve This Math Problem That Is Stumping The Internet?

Have you ever been to the Grand Canyon? Perhaps you have seen it in photographs or videos. Imagine climbing a trail from the top of the canyon down to its base. As you walk, you pass distinct rock layers, each with its own unique colors and textures. In a way, you are traveling back through time as you descend into the canyon!

A matching problem arises when a set of edges must be drawn that do not share any vertices. Graph matching problems are very common in daily activities. From online matchmaking and dating sites, to medical residency placement programs, matching algorithms are used in areas spanning scheduling, planning, pairing of vertices, and network ://

Perfect Numbers The Pythagoreans produced a theory of numbers comprised of numerology and scientific speculation. In their numerology, even numbers were feminine and odd numbers masculine. The numbers also represented abstract concepts such as 1 stood for reason, 2 stood for opinion, 3 stood for harmony, 4 stood for justice, and so on. Their arithmetica had a theory of special classes of numbers.

A perfect number is a positive integer that is equal to the sum of it divisors. However, for the case of a perfect number, the number itself is not included in the sum. Although perfect numbers are regarded as arithmetical curiosities, their study has helped to develop the theory of numbers. For example, if n assumes the value 2, 3, 5, or 7, the expression 2n-1 takes on the value 3, 7, 31, or , all of which are prime. For these values of n we obtain the perfect numbers 6, 28, , and 8, The Neoplatonists Nicomachus of Gerasa and Iamblichus of Chalcis listed these perfect numbers and concluded that they follow a pattern: They alternately end in a 6 or an 8, and there is one perfect number for each interval from 1 to 10, 10 to , to 1, and 1, to 10,

Monday, November 5, Four Types of Slope Pictures This weekend and today were spent attending my first ever student council state convention. It was full of fun and games and amazing speakers, but I have to admit that I am exhausted. I’m so thankful to be sleeping in my own bed tonight. On Friday, I started our next chapter in Algebra 1 over graphing linear equations. I went over the four types of slope. I had heard amazing things about the Slope Dude video on twitter.

Do I have to be good at math if I want to be an Architect? The image above is a page out of my college structures composition notebook … yes, I still have it along with all my other college notebooks, too what end I have no idea. I DID get through it and so would everyone else who wanted to be an architect. Most of the math that I work with is associated with dimensions. Whenever I put together a detail for a project, one of over-riding controls is the size of the parts that come together.

Do I have enough space for all the parts I need? Do things line up? The the components equally spaced apart when required? The arrangement and sizing of the structural steel was worked and re-worked until we got it to this point. There is enough of an offset with the steel beam so that the glass at the floor has a place to set. Did I use some math skills to solve this problem? Absolutely, but none of this is magic and absolutely none of it requires trigonometry, calculus or physics.

My father used to tell me and now I am telling you that you go to college to learn how to learn. This is an important state of mind because learning things that are hard and challenging force you to push yourself and develop skill sets that might be of peripheral value to you.

By Andrew Moseman May 27, Got a terabyte external hard drive at home? Now go buy more and you’ll be able to store all the data that was required to make this math proof. Nature reports on a new paper in arXiv outlining how an international team of researchers created this enormous data-heavy proof. The problem they were trying to prove one way or the other is a question dating back to the s involving Pythagorean triples. There are certain sets of numbers where you can satisfy the theorem with whole integers.
