The number sets that each number belong too are given as follows:

1. Rational.

2. Irrational.

3. Rational.

4. Whole.

5. Whole.

6. Integer.

<h3>What is the classification of the number -4.2?</h3>

It is a terminating decimal, hence it is a rational number.

<h3>What is the classification of the number 3 times square root of 5?</h3>

The square root of 5 is not exact, hence it is a non-terminating decimal, meaning that is an irrational number.

<h3>What is the classification of the number 5/3?</h3>

It is a fraction, hence it is a rational number.

<h3>What is the classification of the number 9?</h3>

It is a positive non-decimal number, hence it is a whole number.

<h3>What is the classification of the square root of 16?</h3>

The square root of 16 is of 4, which is a positive non-decimal number, hence it is a whole number.

<h3>What is the classification of the square root of -8/2?</h3>

The result of the division is of -4, which is a negative non-decimal number, hence it is an integer number.

Answer:

Each pizza have <u>8</u> slices.

Step-by-step explanation:

Given:

At a party to celebrate a successful school play, the drama club bought 9 large pizzas.

Each pizza had s slices.

All together, there were 72 slices of pizza for the club to share.

Now, to find slices each pizza have.

Number of slices each pizza have = $s.$

Number of slices of pizza altogether = $72.$

Total number of pizza = $9.$

Now, to write an equation of this situation:

$9\times s=72$

$9s=72.$

So, to get the slices each pizza have we solve the above equation:

$9s=72$

<em>Dividing both sides by 9 we get:</em>

$s=8.$

Therefore, each pizza have 8 slices.

Answer:

$\frac{x^2}{9}+\frac{y^2}{4}=1$

Step-by-step explanation:

So an ellipse can be expressed in two different but very similar forms:

<u><em>Horizontal Major Axis:</em></u>

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$

<u><em>Vertical Major Axis</em></u>:
$\frac{(x-h)^2}{b^2}+\frac{(y-k)^2}{a^2}=1$

In both equations the length of the major axis is "2a" and the length of the minor axis is "2b"

In the equation you provided, the major axis is horizontal, and the minor axis is vertical.

So looking at the horizontal length, you can see that it's 6, and since this ellipse has a horizontal major axis, that means 2a=6, which means a=3

Looking at the vertical length, you can see that it's 4, and since the ellipse has a vertical minor axis, that means 2b=4, which means b=2

The last thing to note is that the center of an ellipse is (h, k) in the equation, and since here the center is (0, 0) it's (x-0)^2 and (y-0)^2 in the denominator which is just x^2 and y^2

So let's plug in the values into the equation:

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$

(h, k) = (0, 0)

a = 3

b = 2

$\frac{x^2}{3^2}+\frac{y^2}{2^2}=1\\\\\frac{x^2}{9}+\frac{y^2}{4}=1$

Answer:

x = 16

Step-by-step explanation:

10 : 15 5:15 5 x 3 : 15 15:15

x : 24 x/2 : 24 (x/2) x 3 : 24 3x/2 :24

3x/2 = 24 multiply both sides by 2

3x = 48 divide both sides by 3

x = 16
