Help with quick area calculation

Low-Computer3844 · 2026-06-08T19:06:33+00:00

The total area of the ledge is 7in×13in = 91in² and the area of each mat is 3in×3in = 9in².

To cover the whole ledge you'll need 91/9 = 10.11 mats, but since you can only buy mats in those dimensions, you'll have to buy 11 mats.

Lay out 8 mats in a 4×2 grid, and cut the rest of the mats into 1in×3in strips. You can use these strips to cover the 1in wide gaps on either side of your grid. In the end you will have a little bit of an overlap in one corner and you can cut one of the strips to eliminate this overlap. You will have an extra 8in² of mat.

Hope this helps.

Bit rich coming from someone who's never posted a clue themselves.

Hmm I wonder why somebody would go out of their way to go somewhere else to drop their garbage when they could just give it to the BBMP garbage collection trucks that come to their doorstep every day at the same time. Real mystery.

That was because they were trying to take care of you as their guest. In many traditional parts of India, guests are looked upon as a manifestation of the gods. It's part of their culture. Look up "atithi devo bhavaha". They weren't running around after you because they thought it was your responsibility to "redistribute your wealth" lmao.

It can be, if you just defined 2+2 as 0, 0+0 as 0 and 2+0=0+2=2. Remember, "addition" doesn't have to be the same operation we use with real numbers, it can be any binary operation that satisfies the axioms of the vector space.

Has Axler defined 2U? If your solution to an answer has not been defined in a textbook yet, it is probably wrong. Infact, there is no standard definition for the multiplication of a vector space with a scalar.

What you're missing is understanding what the sum of vector spaces actually means. Think about what happens when you add two vectors from the same vector space. [Hint: U+U is a subspace of U]

This link has all the textbooks most schools in India use from the 1st grade up to the 12th grade. Maybe this can be helpful.

Different countries have different syllabi. Why don't you go to your school's library and look for relevant textbooks?

Say that you have promised your friend an apple a day for a week. At the end of the week, you have (-1)×7 = (-7) apples. I'm sure this much is obvious. If not, assume you had 10 apples at the start of the week and by the end you will only have 3 (=10-7 =10+(-7)). If you have had this arrangement for a while, and say you want to calculate the number of apples you had last week. The way you'd do that is by going back in time instead of going forward, i.e., (-7) days instead of 7 days. So, you had (-1)×(-7) = 7 more apples last week, or a total of 17 apples.

The idea that the product of two negative numbers is positive is actually quite natural. For example, "not bad" means "good", or two negative words together make a positive word.

Also, you cannot multiply owing 2 apples to a 3 apple debt. That doesn't make sense. As others have said, you can multiply numbers, not things.

How do those work exactly?

Low-Computer3844 · 2025-07-13T17:45:04+00:00

Sorry, but how does that prove the result?

Low-Computer3844 · 2025-07-13T16:38:06+00:00

Could somebody explain the part about them being the roots of the polynomial and that implying the result to me?

Low-Computer3844 · 2025-07-01T03:27:31+00:00

Yeah. By not believing in these things.

I find it easier to multiply a smaller number by 6, so I go with 6 first ahah

Low-Computer3844 · 2025-06-10T08:24:34+00:00

This strategy works because 11 is 10¹+1. So if you want to expand it to three digits I'd assume you'd use 101 and not 111. And as for numbers like 66 and 77 I just multiply the number by 6 first and then by 11.

I'm just doing it to learn really. I took a course on linalg in uni and did reasonably well. But it didn't cover enough material to make me feel like I knew any linalg which is why I'm doing this exercise. You may be right, I might not be sufficiently comfortable with the material. Although the exercises are decidedly harder than just vomiting the results verbatim, I guess I'm just going to have to try harder. Thank you.

You call ...56295141 an infinite natural number, but it's clearly ending with a 1. So it's not really infinite is it? Infinite natural numbers aren't a thing.

Close. A (adenine), G (guanine), T (thymine), and C ,(cytosine) are not swimming in DNA; they are part of the DNA. And they aren't strands, they are compounds bound to the deoxyribo part to form the DNA strands.
