Answer:

r=1

Step-by-step explanation:

<u>Ratio of Values </u>

A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same

We have a set of tiles numbered 1 to 30:

1,2,3,4,5,6...,29,30

Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is

$\displaystyle r=\frac{even}{odd}$

$\displaystyle r=\frac{15}{15}$

r=1

There are 10 girls and 8 boys in Mr Augellis class. If 5 more girls and 5 more boys join the class, will the ratio of girls to b

ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

I'm not quite sure what a ratio table is, but I can explain it the way I understand it.

The initial ratio is 10:8 which is 1.25 as a decimal.

Now let's add five to each number to represent the kids joining the class, this will result in the following:

15:13 which is 1.153846154 as a decimal.

Therefore, the ratio doesn't stay the same just because you added the same number of people to each group.

Hope this helps :)

Identify the factors of x2 − 4x − 12.

Alborosie

(x-6)(x+2)

When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.

A rectangle has vertices A ( 1, 2) B (1, 7), C ( 4,7) and D (4, 2). What is the area of the rectangle

scoray [572]

The area of the rectangle is 15. To find the area of a rectangle or square the equation is Base*Height. When you graph this you can see the points and count the distance between them which is 3 as your base and 5 as your height. This is my guess.

Factor x^3y^2 - x^5 + xy^3 - yx^3

xenn [34]

<h2>Steps:</h2>

So firstly, we need to factor out the GCF. Since all the terms share a GCF of x, factor that out as such:

$(x)(x^2y^2-x^4+y^3-yx^2)$

Next, I will be factoring by grouping. For this, factor x²y² + y³ and -x⁴ - yx². Make sure that they have the same quantity on the inside:

$(x)(y^2(x^2+y)-x^2(x^2+y))$

Now rewrite the expression as:

$(x)(y^2-x^2)(x^2+y)$

However, we can factor this expression further. Next, we will be applying the difference of squares rule, which is $x^2-y^2=(x+y)(x-y)$ . In this case:

$y^2-x^2=(y+x)(y-x)\\\\(x)(y+x)(y-x)(x^2+y)$

<h2>Answer:</h2>

In short, the factored form of this expression is:

$(x)(y+x)(y-x)(x^2+y)$
