#math questions

3.5h hours of studying math

A line sitting on top of a line so that they are technically two lines but they ARE touching and still going in the same direction

Like this kinda

Are they still considered parallel even tho they are touching?

Is it the "crossing" that makes them not parallel only?

Calculations for that pool challenge thing or whatever its called. For everyone who is too stupid to understand instructions, here you have a visual explanation. Can't be any easier than that. Even with little diagrams.

Use the size of the pool to estimate the size of the paws. About 10 paws fit in the width of the pool, making the estimated length of the paws 3.2 inches. With that size one can calculate width and height of the paw in relation to the length we deduced. Now we need the volume, for that we use a rectangle as an estimation for the paw.

The pool is only half filled, so we calculate the volume of that. Counting the first layer of the pools visible contents, we get 93 paws. We calculate the area of the first layer of the pools contents, and calculating how many paws would cover the whole area, that makes 104 paws. We then use the number of paws we counted, 93, to estimate how much percent of the surface is filled with paws. It's approximately of 90% paws, which we then extrapolate to the whole pools contents. We calculate 90% of the pools volume, and divide it by the paws volume, to deteremine how many paws fit in there.

That gives us 235 paws. With the other available choices for total, crabs and horses, those are my final estimations: 759 total. 235 paws. 247 crabs. 277 horses.

When Was The Equals Sign (=) Invented?

The equals sign (=) was introduced by Robert Recorde in 1557 to denote equality between mathematical expressions.

Why do you need so much honey 😦

I started this blog to motivate myself to study and take hood notes on the recommendation of a blog post about studying. Surprisingly, it’s actually worked. I’m taking nicer notes and actually trying to make them legible/pretty 😅

So far most of my work is done at my job since I have a lot of downtime and computer access (and a boss that doesn’t mind me doing it as long as my work gets done). Trying to work at least an hour/day or 10 problem types learned, depending on which is last 🥲 Problems are getting harder and my math TSIA2 exam needs to be done by the 21st of July.
