So: the baking pan is a cylinder so you need the equation which gives you the volume of a cylinder. This is the area of the base of the cylinder multiplied by the height of the cylinder. 
The base is a circle and you know the radius. The area of a circle is radius^2*pi.
Therefore: 6^2 * 3.14 = 113.04

Now, you know the volume of the batter which is poured into the pan: 550 cm^3. You know the area of the base of the cylinder: 113.04. You only need the height, which you can calculate. 
550 = 113.04 * height
Divide by 113.04
4.9 = height.


What is the product of (x + 3)(2x – 1)

Answers

Answer:

The product of  (x + 3)(2x -1)=2x^2+5x-3

Step-by-step explanation:

Given : Two expressions (x + 3) and (2x – 1)

We have to find the product  of given expression that is  (x + 3)(2x -1)

Consider the given expression (x + 3)(2x -1)

Multiply each term of first bracket with each term of second bracket

\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd

we have,

=x\cdot \:2x+x\left(-1\right)+3\cdot \:2x+3\left(-1\right)

Simplify, -(-a)=+a

we have =2xx-1\cdot \:x+3\cdot \:2x-3\cdot \:1

Simplify, we get,

=2x^2-x+6x-3

Adding like terms, we have,

=2x^2+5x-3

Thus, the product of  (x + 3)(2x -1)=2x^2+5x-3

Umm
(X+3)(2x-1)
=2x square -x + 6x - 3
=2x square +5x -3

2x+y=3 -4x-4y=-8 using elimination?

Answers

 2x + 1y =   3 ⇒ 8x + 4y = 12
-4x -  4y = -8 ⇒ -4x - 4y = -8
                                  4x = 4
                                   4     4
                                    x = 1
                            2x + y = 3
                          2(1) + y = 3
                               2 + y = 3
                             - 2        - 2
                                     y = 1
                               (x, y) = (1, 1)

Step-by-step explanation:

Find the greatest common factor of 15x 2 y 3 and -18x 3 yz.

Answers

Answer:

Greatest common factor of  15x^2y^3 and -18x^3yz is  3x^2y

Step-by-step explanation:

Greatest common factor is the common factor for two or more numbers such that greatest common factor divides both the number.

We find  Greatest common factor by

  • doing prime factorization and then
  • taking common factors from all the factors and
  • if they do not have nay term common then  Greatest common factor is 1.

Given Numbers are 15x^2y^3 and -18x^3yz

First we do prime factorization of 15x^2y^3.

15 can be written as product of prime 3 and 5, so

15x^2y^3=3 * 5 * x* x * y * y * y

and Similarly, -18x^3yz can be written as,

-18x^3yz=-3 * 3* 2 * x* x * x* y* z

Thus, taking common from both the terms,we get,

Greatest common factor as 3x^2y


Multiply the GCF of the numerical part 3 and the GCF of the variable part x^2y to get
3x^2y.
