If Einstien's theory of Relativity proves that Euclidian Geometry is not always correct depending on the strength of a gravitational field, then why isn't only non-euclidian geometry applied universally? Is it because Euclidian Geometry is right most of the time?

What is the area of a semicircular region tangent to two sides of a unit square, with endpoints of its diameter on the other two sides?

My teacher told me the answer is pi(3-2sr2)
how do you do this?

Hi, I'm having a bit of trouble with conversion factors in chemistry. The book is explaining it in an extremely complicated way, and I'd do it in my own way much quicker, but you have to show the work using their steps, etc., so I need to figure out what exactly it's talking about. Here's an example of the problem:

A car can travel 40.0 miles on one gallon of gasoline. How many kilometers per liter is this? (1.61 km = 1 mi; 1L = 1.06 quarts; 1 gallon = 4 quarts)

I *think* that they want it to be set up something like this:

40 mi /1 gallon X 1.61 km/ 1 mi X 1.06 quarts/ 1 L X 1 gallon/ 4 quarts


... which, if solved by the methods they present in the book, would come out to 64.4 km / .265 L. When this is put into the format of X km/L, would it be 243 km/ L? Please explain this to me! THANK YOU

Ok. Here is the problem.

In a large equilateral triangle is a inscribed smaller one, its vertices at trisection points of sides of the larger. Is the perimeter of the larger triangle is 9, what is the perimeter of the smaller equilateral triangle?

ANY help would be appreciated. I also have to explain my answer so if you could include that it would be great!!

I heard there once was.
Humans and apes are 99% the same.

I know it could not happen between human and e.g.horse.
