2022: Assign the rectangle the gender you prefer.

[–] Trash_Panda 0 points 8 points (+8|-0) ago 

[ ] male

[ ] Female

[ ] Otherkin

[X] it is wrong to assume the rectangles gender

[–] Lagmonster 0 points 3 points (+3|-0) ago 

Its wrong to think the rectangle is a rectangle

[–] Mr_Quagmire 0 points 15 points (+15|-0) ago 

You colored the rectangle white? Fail.

I don't know how they got 16 and I'm pretty sure I don't want to know

Common Core:

20/5(2 * 2) --> 4*(2 * 2) -- > 4(4) --> 4 * 4 = 16.


20/5(2 * 2) --> 20/5(4) --> 20/20 = 1.

The "common core" way goes left --> right, whereas the standard Order of Operations goes parentheses --> exponents --> multiplication/division --> addition/subtraction.

Edit: I am currently studying mathematics. Common Core is extremely confusing. The only reason why I was able to tell you that is because I recently reviewed and studied Order of Operations as a mathematical concept in order to improve my understanding of things that I forgot while studying higher level mathematics.

That makes me want to vomit.

Textbooks from the 50s tend to be superior to modern ones. The language was more descriptive and to the point. The information for many subjects remains largely unchanged too.

[–] ThePoliceTookMyGuns ago 

In the 90s and early 2000s I had textbooks from the 70s. They were much better than the post 2000 crap we got in middle school.

Accurate. I have a relative that was a school principal and teacher for 40 years. She talks about this a lot.

[–] CowWithBeef ago 

Does she think the quality of students has changed over 40 years, or the school?

[–] Floppyhorsecock 0 points 1 point (+1|-0) ago 

For sure the approved curriculum. Teachers used to have a lot more say in what and how they taught. It became just classes to teach how to pass standardized tests.

Id have to ask about the student quality. She griped directly about over the years Teachers autonomy being stripped.

This results in Teachers just sticking to test prep because if the students dont do well the school gets less money.

There was more to it but that's the gist of it.

(((Common core))) was created to try and teach niggers how asians and whites do math implicitly to try and close the gap in math. It didn’t work. I bet the higher ups in education are seething that niggers are retarded at every single income level compared to whites and asians.

Are we to assume the radii are on centerline? This is a poorly drawn print. No conventions at all.

[–] AttackHelicopter 0 points 2 points (+2|-0) ago 

Accurate for high school graduation criteria, but I do have to add that I had to relearn the 1940s math when I went back to college around five years ago (at around 40 years of age) to get a different degree. My mathematics credits (among others) had "expired" by the university's policy. Totally not a money grab... Anyway, I went back for Dietetics and was motivated to learn the math again by the "professors" who had significant surface area...and not in a good way.

[–] Ken_bingo2 0 points 2 points (+2|-0) ago 

I had to start over again on maths too. Starting way down at geometry through calc III and diff eq. I am quite confident in my skills and so are my peers. It is not a great image, but it looks like 1940 would require a compass unless you were going to make some assumptions. That is a standard tool to have in geometry, however.

[–] tourgen 0 points 1 point (+1|-0) ago 

It's a poor image, but you can solve it using the information shown. This gets posted regularly. I posted the answer a few weeks ago. You can assume the circular cutouts are quarter-circles, the same as the rounded corners but inverted. The difference in area between a square and a quarter-circle arc is a useful intermediary calculation.

[–] 1390MyEggo 0 points 1 point (+1|-0) ago 

That's what I was thinking as well. I assume that in the 1940's example R is the radii of the circles cut out from the rectangle which would of course let you calculate their area, but you have no way of knowing exactly how much of the circle to "cut out" unless you guestimated. I hate to admit it, but I went up to calculus (just Calc 101) in college and I would still struggle with the 1940's example.

Dietetics. To be a Dietitian. An RDN. Are you trolling me or just helping me lose faith in the future of our species?
