**Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below.
**

**
**

**Which is Zelie’s error?
**

**
**

**Zelie should have divided both numbers by 14.
**

**Zelie should have written the ratio as 28/7.
**

**Zelie should have written the ratio as 14/8.
**

**Zelie should have subtracted 14 from both numbers.
**

Original length of pool = 28ft

If he found that it need to be 14ft longer then the actual measure = 14th

given equation is;

(28 - 7)/14 - 7 = 14/7

Scale constant = original length/actual length

Scale constant = 28/14

Scale constant = 2

Hence the scale constant is 2

**According to the option, Zelei should have divided both numbers by 14.
**

**Answer:**

Zelei should have divided both numbers by 14

The sum of three consecutive odd integers is-219. What is the first number in the set?

**Answer:**

-75

**Step-by-step explanation:**

Let us consider the first odd number to be 'x'.

Thus:

1st odd number: x2nd odd number: x+23rd odd number: x+3According to the question, the sum of these three consecutive ODD numbers should be equal to -219

So,

x + x + 2 + x + 4 = -219

3x + 6 = -219

3x = -225

x = -75

tomorrow is the submission :(

**Answer:**

(3a +6b) (9a² - 18ab + 36b²)

**Step-by-step explanation:**

27 = 3 * 3 * 3 = 3³

216 = 6 * 6 * 6 = 6³

**a³ + b³ = (a + b)(a² - ab + b²)**

27a³ + 216b³ = (3a)³ + (6b)³

= (3a + 6b)( (3a)² - 3a*6b + (6b)² )

= (3a +6b) (9a² - 18ab + 36b²)

Mal always solve the equation of negative 5 x minus 16 equals 8, his work is shown below identify the era where it was made step one not gonna 5 x minus 16 plus 16 equals 8 plus 16 Sep 2 negative 5 x equals 24 step, 3 negative 5 x, over 5 equals 24 over 5 step 424 are 5.

**Given:**

The equation is

[tex]-5x-16=8[/tex]

**To find:**

The error and correct solution.

**Solution:**

We have,

[tex]-5x-16=8[/tex]

Add 16 on both sides.

[tex]-5x-16+16=8+16[/tex]

[tex]-5x=24[/tex]

Divide both sides by -5.

[tex]\dfrac{-5x}{-5}=\dfrac{24}{-5}[/tex]

[tex]x=-\dfrac{24}{5}[/tex]

**Third step is incorrect because he divide the equation by 5 instead of -5.**

**Therefore, the correct solution is **[tex]x=-\dfrac{24}{5}[/tex]**.**

Graph the exponential function.

f(x) = 4^x

Plot five points on the graph of the function. Then click on the graph-a-function button.

Exponential Function doesn't have a graph that intercepts x-axis only if it is f(x) = a^x (when a>0 and a ≠ 1)

If you want to plot five points to graph the function then. I'd rather do from negative number to positive number.

Substitute from -3≤x≤1 (We get 5 points)

f(-3) = 4^-3

f(-3) = 1/4^3

f(-3) = 1/64 (First point) (-3,1/64)

f(-2) = 4^-2

f(-2) = 1/4^2 = 1/16 (Second point) (-2,1/16)

f(-1)=4^-1 = 1/4 (Third point) (-1, 1/4)

f(0) = 4^0 = 1 (Fourth point) (0, 1)

f(1) = 4^1 = 4 (Fifth point) (1,4)

An average swimming pool contains 19200 gallons of water. The pool needs drained at the end of the summer. Water drains from the pool at the rate of 12 gallons per minute. Which equation can be used to find the volume, V, of the water in the pool m minutes after draining begins?

Answer:

V = 19200 - 12m

Step-by-step explanation:

The pool contains 19200 gallons of water.

Now we are told that water drains from the pool at the rate of 12 gallons per minutes.

Now, we want to find the volume, V, of the water in the pool, "m" minutes after draining begins.

Since water drains at 12 gallons per minutes, it means that after "m" minutes, the total amount that would have been drained is 12m gallons.

Thus, total volume V left after m minutes can be expressed as;

V = 19200 - 12m

The **equation **of the **line **shown in the graph is y = 4x / 5 -2.

The **slope **of the **line **is a **tangent angle **made by line with horizontal. i.e. m =tanx where x in degrees.

Here,

Points located on the graph that lies on the line are (0, -2), and (2.5, 0)

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

Substitute the value in the above equation,

m = 0+ 2 / 2.5 -0 = 20/25

m = 4 / 5

The equation of the line is given as

y - y₁ = m (x - x₁)

Substitute the one point (-2, 0) and m in the above equation,

y + 2 = 4/5 (x - 0)

y = 4x / 5 -2

Thus, the **equation **of the **line **shown in the graph is y = 4x / 5 -2.

Mikel has a chance to win a trip on a TV game show. All he has to do is win the “Shopping Game". In

this game, Mikel is shown six grocery store items without being shown the prices. He must buy

multiples of items until he has a total between $20 and $21 inclusive. If he doesn't reach $20 with his

first item, he continues buying items and adding to his total, until he either wins by getting an amount

between $20 and $21, or he loses by going over $21 or by buying all items and being less than $20.

First, Mikel buys six bottles of shampoo.

Solve the inequality. Round each answer to the hundredths place.

**Answer: **

**$20 <= X < = $21**

**Step-by-step explanation:**

**
**

**You are told that he loses by going over $21 or by buying all items and being less than $20.
**

**
**

**That means the total amount of the items bought must be equal to 20 dollars or 21 dollars or be within the two amount of money.
**

**
**

**If Mikel buys six bottles of shampoo, x represents the total amount for the six bottles of shampoo. Then, the compound inequalities for this expression will be x less than or equal to 21 dollars and x greater than or equal to 20 dollars. That is,

A set of data has a mean of 58 and only one outlier of 92. Which statement about this data set must be true?

The range is 34.

The range is 34.

The mode is equal to the mean.

The mode is equal to the mean.

The mean is greater than the median.

The mean is greater than the median.

The distribution curve is skewed to the right.

**Answer:**

The correct option is;

The distribution curve is skewed to the right

**Step-by-step explanation:**

The given parameters are;

The mean = 58

The outlier = 92

Given that the outlier, P, can be found from the following formula, we have;

P > Q₃ + 1.5·IQR = (Q₃ + 1.5 (Q₃ - Q₁)

92 > (Q₃ + 1.5 (Q₃ - Q₁)

Given that mean = 58

Therefore, the IQR, and Q₃ are relatively small compared to the outlier, and the data is skewed, with the more smaller numbers than there are large numbers which makes the distribution curve to be skewed to the right.
