The perimeter of the figure is sum of the side of the figure. If figure is dilated by factor of 3, means that each side of the figure is dilated by 3.
The addition of dilated side to obtain the perimeter results in 3 times the original perimeter.
So new perimeter is 3 times larger than the preimage. Option D is correct.

The graph of a function is shown below . What is true about the function between x=1 and x=5
The true statement about the function between x = 1 and x = 5 is that the function decreases at this interval
How to interpret the graph?The graph of a function represents the given parameter
Also, we have the interval to be
x = 1 and x = 5
From the function, we can see that
f(5) < f(1)
This means that:
The function values decrease from x = 1 to x = 5
The general conclusion of this is that this interval represents a decrement in the values of the function

What kind of compound inequality is 1-4x<21 and 5x+2>22?
The compound inequality is 5x + 2 > 22 large i.e., x > 4.
Given,
1 - 4x < 21 and 5x + 2 >22
What is Compound Inequality?
A compound inequality is an inequality that merges two inequalities either by using "and" or "or". Sometimes "and" won't be specifically mentioned but it is understood. For example, 1 < x < 3 is nothing but "x > 1 and x < 3".
To solve the above Inequality:
1 - 4x < 21 and 5x + 2 >22
Now,
1 - 4x < 21
=> 1 - 21 < 4x
=> -20 < 4x
=> x > -5
5x + 2 > 22
=>5x > 20
x > 4
Hence, The compound inequality is 5x + 2 > 22 large i.e., x > 4.

Variance = 209.89
Standard Deviation=14.4875
Explanation:
The perimeter of a rectangle is 260 feet find the length and width if the length is an even integer in the width is 5 times the next consecutive even integers
The rectangle is 20 feet long and 50 feet wide.
Let the length be x. So, the next consecutive integer will be (x + 2). Width of rectangle = 5(x + 2). As per the formula, perimeter of rectangle is 2(length + breadth).
Keep the values in formula to find the value of x.
2(x + 5(x + 2)) = 260
Firstly solving the inner bracket
2(x + 5x + 10) = 260
Now again opening the bracket
2x + 10x + 20 = 260
Performing addition
12x = 260 - 20
Performing subtraction
12x = 240
x = 240 ÷ 12
Performing division
x = 20
Length of rectangle = 20 feet
Width of rectangle = 2(20 + 5)
Width of rectangle = 2×25
Width of rectangle = 50 feet
So, the length and width of rectangle is 20 feet and 50 feet.

Use the following image to answer the question.CBFGHHow would you identify IE?
Given:
Center of circle = Point O.
Let's use the image to identify line IE.
Since E is the center of the circle and point I is on the circumference of the circle, line IE starts from the point I and goes to the center of the circle, point E.
Hence, we can say line IE is the radius of the circle.
The radius of a circle can be said to be the distance from the center of a circle to any point on the circumference of the circle.
Therefore, IE is the radius of the circle.

[tex]undefined[/tex]there is a stack of cards, each given a different number 1-10, suppose we select a card randomly from the stack, replace it, then randomly select a card. what is the probability that the 1st card is an ODD number and the second card is Less then 5?
Given that:
- A stack of different cards numbered from 1 to 10.
- A card is randomly selected and then replaced. Then another card is randomly selected.
• You need to find the probability that the first card is an odd number.
By definition, Odd Numbers are those numbers that cannot be divided by 2. In this case, these are:
[tex]1,3,5,7,9[/tex]Knowing that the total number of cars is:
[tex]10[/tex]You can set up:
[tex]P(X=ODD)=\frac{5}{10}[/tex]Then:
[tex]P(X=ODD)=\frac{1}{2}[/tex]• You need to find the probability that the second card is less than 5.
Notice that the numbers cards from the stack that are less than 5 are:
[tex]1,2,3,4[/tex]Therefore, you can set up that:
[tex]\begin{gathered} P(X<5)=\frac{4}{10} \\ \\ P(X<5)=\frac{2}{5} \end{gathered}[/tex]• Now you can set up:
[tex]P=\frac{1}{2}\cdot\frac{2}{5}[/tex]Solving the Multiplication, you get:
[tex]\begin{gathered} P=\frac{1\cdot2}{2\cdot5} \\ \\ P=\frac{2}{10} \\ \\ P=\frac{1}{5} \end{gathered}[/tex]Hence, the answer is:

A cereal box says that now it contains 20% more. Originally, it came with 18.5 ounces of cereal. How much cereal does the box come with now? Explain your reasoning.
Percentages can be expressed as decimals. Percentage of something can be found by multiplying the number by the decimal.
20% = 0.20
20%(18.5)
0.20(18.5)

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. Four broad categories can be used to classify different types of functions. One-to-one function, many-to-one function, onto function, one-to-one, and into function—all based on the element.So, matching each function with a correct scenario:
