judy uses 12 tiles to make a mosaic. Eight of the tiles are blue. What fraction, in simplest form, represents the tiles that are blue?

Answers

2/3 is the simplest form  which represents the tiles that are blue.

What is Fraction?

A fraction represents a part of a whole.

Given that Judy uses 12 tiles to make a mosaic.

Eight of the tiles are blue

We need to find the fraction in simplest form to  represents the tiles that are blue

As 12 are the total number of tiles which can be taken in the denominator

8 blue tiles are part of the whole tiles

So we have to divide 8 by 12

8/12

as 8 and 12 are multiples of 4

2/3

Hence, 2/3 is the simplest form  which represents the tiles that are blue.

Which constant would you add to the RIGHT side of the
quadratic equation in order to solve by completing the
square? Remember, this is a two-step process​

Answers

ANSWER

The correct answer is D

EXPLANATION

The given quadratic expression is

3 {x}^(2) + 8x = - 1

Divide through by 3

{x}^(2) + (8)/(3) x = - (1)/(3)

We now add the square of half the coefficient of x because the coefficient of the quadratic term is now unity.

The constant we would add is

{( (4)/(3) )}^(2) = (16)/(9)

The correct answer is D

Answer: Option D.

Step-by-step explanation:

Given the quadratic equation 3x^2+8x=-1, you can observe that the leading coefficient is not 1, then you have to divide both sides of the equation by 3:

(3x^2+8x)/(3)=(-1)/(3)\n\nx^2+(8)/(3)x=(-1)/(3)

Now, you can observe that the coefficient of the x-term is (3)/(8), so you must divide it by 2 and square it. Then you get:

(((8)/(3))/((2)/(1)))^2=(16)/(9)

Therefore, you must add (16)/(9) to both sides of the equation.

v = 3 because if you use the inverse operation of multiplication you do 15/5 which equals 3
15+5v. The sum which is adding and the product which is multiplying. So, 15 plus 5 times "v"!
