Hi Paula:

A mathematical logic question.

You need to get all of the measurements in the same units.

- A cubic yard is 1 yard x 1 yard x 1 yard

- equals 3 ft x 3 ft x 3 ft

- equals 27 cubic feet,

so once you have the volume of the pipe in cubic feet, you divide by 27 to get the volume in cubic yards.

- Volume of a cylinder (the pipe) is the cross sectional area X length.

- Area equals Pi x r squared.

- equals 22/7 x 1 x 1

equals 3.14#####

times length (20)

equals 62.857### cubic feet volume

divide by 27 cubic feet

equals 2.328### cubic yards.

- The answer is always the easy part.

- what is important is knowing exactly what the question is, and

- determing what calculations are needed to get the answer.

Wasn't that better than if I'd just said 2 1/3 cubic yards?

Cheers

To find the answer, take the square of the first number and subtract from it the square root of the second number:

5 squared is 25

sgrt of 4 is 2; 25-2=23

9 squared is 81

sqrt of 9 is 3; 81-3=78

so:

3 squared is 9

sqrt of 81 is 9; 9-9=**0**

The answer is** zero**!

5 squared is 25

2012 is answer

(5) square = 25 , 25-5 = 20 , (5)square = 25 , 25+5 = 30 so == 2030, (3)square = 9 , 9+3 = 12, (5)square = 25 , 25-5 = 20 so == 1220, now

5) square = 25 ., 25-5 = 20, 3)square = 9 , 9+3 = 12

the +,-,+,- series is continued.

3:4=n:12

3:4=9:12

n=12

Divide 12 to 4 you get 3. Multiply 3 to 3 and you get 9.

Please rate my answer if you appreciate it.

In mathematics, **special products** are of the form:

(a+b)(a-b) = a2 - b2 (Product of sum and difference of two terms) which can be used to quickly solve multiplication such as:

301 * 299 = (300 +1)(300-1) = 3002 - 12 = 90000 - 1 = 89999__types__

1. Square of a binomial

(a+b)^2 = a^2 + 2ab + b^2

carry the signs as you solve

2. Square of a Trinomial

(a+b+c)^2 = a^2 + b^2 + c^2 + 2ab + 2ac + 2bc

carry the sings as you solve

3. Cube of a Binomial

(a+b)^3 = a^3 + 3(a^2)b + 3a(b^2) + b^3

4. Product of sum and difference

(a+b)(a-b) = a^2 - b^2

5. Product of a binomial and a special multinomial

(a+b)(a^2 - ab + b^2) = a^3-b^3

(a-b)(a^2 + ab + b^2) = a^3-b^3

(a+b)(a-b) = a2 - b2 (Product of sum and difference of two terms) which can be used to quickly solve multiplication such as:

301 * 299 = (300 +1)(300-1) = 3002 - 12 = 90000 - 1 = 89999

(a+b)^2 = a^2 + 2ab + b^2

Hi
5+3=28, 9+1=810, 8+6=214, 5+4=19, 38+20=1858

First find difference and then sum............. If we take 5+3 =28, 5-3=2 and 5+3=8 so answer is 28 like wise

7+3 = 410 So answer is 410

Perfect squares are the product of a whole number and itself. Given that 22 squared = 484, and 23 squared = 529, I'd say the answer to your question is that there is no square number between 490 and 500.
