Isabella had a week to read a book for a school assignment. She read an average of 36 pages per day for the first three days and an average of 44 pages per day for the next three days. She then finished the book by reading 10 pages on the last day. How many pages were in the book?

36 X 3=108 pages she read in the first 3 days

44 X 3=132 pages she read the following 3 days

108+132+10=250 number of pages in the book.

1-What is the amount that he paid for the lot? Is it 7,000,000 or 70,000?

2-Man loses the sp of 30 article? What does "sp" mean?

UMMMMM
 

Alan: I think you overdid this time!!!!!!

Kids are simply learning "proportionality", despite the fact that they say "one number=another!". In this case, I'm certain that the young person meant: If 72: 46, then what is 106:?. That is all folks!.

[(x + 1) − y]^2

This is just a perfect square.

\([(x + 1) − y]^2\\ = (x+1)^2\;\;-\;\;2*(x+1)*y\;\;+\;\;y^2\\ = (x^2+2x+1)\;\;-\;\;2y(x+1)\;\;+\;\;y^2\\ = x^2+2x+1\;\;-\;\;2xy-2y\;\;+\;\;y^2\\\)

Yep the jamesmachine has got it!

Red is very offended by this.  He is still around and no one notices.    

I tell him that I am here for him but sometimes he wants more....   

Congratulations SpawnofAngel. 

You keep really good company on the leaderboard too :))

(Most,  but not all of the important people are there  LOL)

If 72 is a base 8 number then in base 10 it is:  7*8 + 2 = 58

If 46 is a base 13 number then in base 10 it is 4*13 + 6 = 58

If 106 is a base 8 number then in base 10 it is 1*8^2 + 6 = 70

In base 13 the base 10 number 70 is  55  (i.e  5*13 + 5 = 70)

So, if 72 equals 46 then 106 equals 55

I believe that a woman meteorite that smashed into the Yucatan peninsula in Mexico about 65 million years ago. There are other theory on what killed all the dinosaurs, like by volcano or tsunami, but I believe on this theory.

1/5 of 200 is 40

1/2 of 40 is 20

1/4 of 20 is 5

1/4 of 1/2 of 1/5 of 200 is:

​5

If you mean the 124 repeats forever i.e. 0.124124124124......, then treat it as follows:

        x = 0.124124124124.....     Multiply by 1000

1000x = 124.124124124......  

Subtract the first from the second:

999x = 124

Divide both sides by 999:

x = 124/999   so -0.124124124.....  =  -124/999

. 

-0.124= - 124/1000
