Irene makes 4 2/3 cups of pancake batter . she splits the
kvv77 [185]

Answer:


Step-by-step explanation:

An estimate is usually a guess, but I somehow think that's not what you want.

She starts with 4 2/3 cups of batter. When she divides it into two, one of the batters has 2 1/4 cups. That's the one she puts blueberries in.

The other batter is the one you are interested in. How big is it?

Estimate: One

The estimated size would be 4 2/3 - 2 1/3 = 2 1/3 which is an estimate. It is just taking the closest number to use so you don't have to grab your calculator.

Actual Size: Two

4 2/3 - 2 1/4 is the size of the second batter. Since 2/3 is greater than 1/4 you need only subtract the whole numbers and then the fractions.

<em><u>Whole number subtraction:</u></em> 4 - 2 = 2

<em><u>Fraction subtraction:</u></em> 2/3 - 1/4

Find the Lowest common multiple between 3 and 4: It is 12. 3 and 4 are prime to each other. They have nothing in common.

  • 2/3 to 12s: (2*4)/(3*4) = 8 / 12
  • 1/4 to 12s: (1 *3) / (4*3) = 3/12
  • 8/12 - 3/12 = 5/12

So the actual size of the batter containing the walnuts is 2 5/12

Find S in formula A=5²<br><br>Need help plss this for my exam​
Kruka [31]

Answer:

S  = √A

Step-by-step explanation:

  Given that;

        A = S²

Finding S implies making S the subject of the expression.

 To do this;

       A = S²  

      Take the square root of both sides of the expression;

   

   √A = √S²

  The square-root of the square of S = S;

    S  = √A

Factor completely<br> (X^2 + x - 6) (2x^2 + 4x) =
Vikki [24]

Answer:

= 2x^4 + 6x^3 - 8x^2 + 24x

= 2x ( 2x^3 + 3x^2 - 4x + 12)

Step-by-step explanation:

(X^2 + x - 6) (2x^2 + 4x) =

Let's open the brackets carefully

x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x

= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x

= 2x^4 + 6x^3 - 8x^2 + 24x

= 2x ( 2x^3 + 3x^2 - 4x + 12)
