What's the REAL square root of pi?

Answers

Every positive number has two square roots. Since pi itself is irrational, you can be sure that its square roots are also irrational, so they can't be written exactly using digits. They're roughly +1.77245... and -1.77245... (both rounded).

What is a factor tree, and how do you know when a factor tree is completed?(5th grade math Please help me.)

Answers

A factor tree starts with one number, such as 8. You draw to lines, and at the end of each is a possible way to divide 8, such as 4 and 2, because 4*2=8. Then, you divide 4 by 2, which is the only possible way without getting a 1 or a 4. Then, since 2 cannot be divided by 2 or 1.That is a complete factor tree. You can tell if a factor tree is over if you end up with a prime number.
A factor tree is a tree to represent what are the factors of the number.
Ex: 20:1,2,4,5,10

1x20
2x10
4x5
5x4
10x2
All of this equals 20
*in a factor tree you have to include all the factors of a number

If the perimeter of a square is 40 mm how long is each side of the square

Answers

They are all 10mm long because 10*4 is 40mm so hoped I helped
Since the perimeter of the square is 40 then you will divide 40 by 4 wich will equal 10, so each side of the square is 10 mm long.

My Work:

40/4= 10
10+10+10+10=40 or 10x4=40
