Rectangle A'B'C'D' was created by dilation Rectangle ABCD using D as the center of dilation.
What is the scale factor of the dilation?
Based on the scale factor, how many copies of ABCD, including the original, should fit inside A'B'C'D?
In Rectangle , 16 copies of ABCD fit inside A'B'C'D'.
What is a rectangle, exactly?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral.
The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.
DA = 3
D'A' = 12
Scale factor DA/D'A' = 3/12 = 1/4
The scale factor = 1/4
The scale factor = 1/4
area ratio = 1/16

A store sells an 8-pound bag of flour for $18.80. If larry can buy a 2-pound bag of flour at the same rate, what would be the price of the 2-pound bag?
Answer:
$4.70
Step-by-step explanation:
First, you need to divide 18.80 by 8.
18.80/8 = 2.35
2.35 is the unit price for one (1) pound bag of flour,
Multiply by 2 to find the price of a two (2) pound bag.
2.35 * 2 = 4.7
$4.70 is the price of a two-pound bag.

The first equation in the system models the height, h, of a falling volleyball as a function of time, t. the second equation models the height, h, of the hands of a player jumping up to spike the ball as a function of time, t. which statement describes the situation modeled by this system?
The volleyball is 14 feet above the ground at the instant the player begins her jump.
What is the equation of motion?It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.
We have two equation for two different situations:
[tex]\rm h(t) = 14 - 16t^2\\[/tex] (falling volleyball as a function of time t)
[tex]\rm h(t) = 7+24t-16t^2[/tex] (the hands of a player jumping up to spike the
ball as a function of time t)
First, we have to find the height of the ball above the ground at the instants the player begins to jump:
At t = 0 when the player begins to jump
Put t = 0 in the second equation, we get:
[tex]\rm h(0) = 7+24\times 0-16\times0^2[/tex]
Height of the hand, h = 7 units
Now put t = 0 in the first equation, we get;
[tex]\rm h(0) = 14 - 16\times0^2[/tex]
h = 14 units.
Thus, the volleyball is 14 feet above the ground at the instant the player begins her jump.

A hockey season ticket holder pays $99.00 for her tickets plus $3.00 for a program for each game. A second person pays $14.00 for a ticket to every game but doesn't buy programs. In how many games will they have paid the same amount?
The two person will pay the same amount of money when they both watch 9 hockey games.
How to find the equation and use it to find cost?A hockey season ticket holder pays $99.00 for her tickets plus $3.00 for a program for each game. Therefore,
y = 99 + 3x
where
y = total cost
x = number of game
A second person pays $14.00 for a ticket to every game but doesn't buy programs. Therefore,
y = 14x
The number of games they will have the same amount is as follows:
99 + 3x = 14x
99 = 14x - 3x
99 = 11x
x = 99 / 11
x = 9
Therefore, they will have the same amount when they watch 9 games.

What is the Pythagorean Theorem and when can you use it?
Step-by-step explanation:
The Pythagorean Theorem is a useful tool that shows how the sum of the areas of three intersecting squares can determine the side lengths of a right triangle.
You use the Pythagorean Theorem when you know the lengths of two sides of a right triangle and you want to figure out the length of the third side.
Suppose a normal distribution has a mean of 98 and a standard deviation of
6. What is P(x s 110)?
A. 0.975
B. 0.84
O C. 0.025
OD. 0.16
The probability (x s 110) is 0.975, the correct option is A.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Median represents the middle value of the given data when arranged in a particular order.
We are given that;
Mean=98
Now,
To find the probability that x is less than or equal to 110 for a normal distribution with mean 98 and standard deviation 6, we need to use the standard normal table or a calculator.
Using the standard normal table, we first need to convert x to a z-score using the formula:
z = (x - mean) / standard deviation
Plugging in x = 110, mean = 98 and standard deviation = 6, we get:
z = (110 - 98) / 6
z = 2
This means that x = 110 is equivalent to z = 2 on the standard normal distribution.
Now we look up the value of z = 2 on the table and find that it corresponds to an area of 0.9772. This means that P(z ≤ 2) = 0.9772.
However, this is not the answer we want. We want P(x ≤ 110), which is the same as P(z ≤ 2). The table gives us the area to the left of z, but we need to subtract it from 1 to get the area to the right of z. This is because P(x ≤ 110) = P(z ≤ 2) + P(z > 2) = 1.
Therefore,
P(x ≤ 110) = P(z ≤ 2)
P(x ≤ 110) = 1 - P(z > 2)
P(x ≤ 110) = 1 - (1 - P(z ≤ 2))
P(x ≤ 110) = P(z ≤ 2)
P(x ≤ 110) ≈0.9772
Therefore, by the given mean the answer will be 0.975.

Letter C
In this case, if you draw a horizontal line across the middle of the letter "C" and fold the letter, each half would be the same. The top half of "C" mirrors the lower half.
Other Examples
The lowercase letter "l" also has 2 lines of symmetry. You can draw both a horizontal and vertical line across the letter and each side will mirror the other.

Natasha is a regional manager for a chain of supermarkets. she has been tasked with researching the weekly sales records of two branch locations over the past month, which she must present to her board of directors. she was able to assemble the relevant information in the table below, but it is scrambled and hard to read. sales are listed in thousands of dollars. week 4 1 1 3 4 2 3 2 sales 16.3 17.8 23.1 15.2 20.2 23.4 22.9 17.6 branch north south north south south north north south in order to make the data more readable, natasha has decided to put it into a graph. which of the following graphs accurately matches the information in the table? i.a bar graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, from 15 to 23. week 1 north, 23.1; week 2 north, 23.4; week 3 north, 22.9; week 4 north, 16.3. week 1 south, 17.8; week 2 south, 17.6; week 3 south, 15.2; week 4 south, 20.2. ii. a line graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, going from 15 to 23. iii.a graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, going from 15 to 23. points are plotted all over the graph. iv. a pie chart titled sales (dollars times 1,000). north 1, 16.3; north 2, 17.8; north 3, 23.1; north 4, 15.2; south 1, 20.2; south 2, 23.4; south 3, 22.9; south 4, 17.6. a. i b. ii c. iii d. iv
The graph which accurately matches Natasha's data for the chain of supermarkets is a bar graph.
How to read the data from the table?A table is a way to represent the data of two or more variables.
To read the data from the table look for the value of one variable, and get the resultant value of another variable from the corresponding block.
Natasha was able to assemble the relevant information in the table below,
Sales are listed in thousands of dollars.
Week - 4 1 1 3 4 2 3 2
Sales- 16.3 17.8 23.1 15.2 20.2 23.4 22.9 17.6
Branch- North South North South South North North South
To show the sales with respect to the time period, the best data chart is the bar graph. In a bar graph, the height of the bars is proportional to the data value it possesses.
Here, for the sales by the Natasha the bar graph should be used as, the bar graph has a week on the x-axis and sales (dollars times 1,000) on the y-axis, from 15 to 23.
Week 1 North, 23. 1; week 2 north, 23. 4; week 3 north, 22. 9; week 4 north, 16. 3. Week 1 south, 17. 8; week 2 south, 17. 6; week 3 south, 15. 2; week 4 south, 20. 2.
