The formula for a circle is πr².
Therefore, we can divide the area of the circle by 3.14, and then square root it. 490.63/3.14=156.25... If you square root that, you get 12.5. Same thing with the other circle. 219.45/3.14=69.888... If you square root that, you get 8.36. Now that we have the radius, we can multiply that by two to find the diameter. And we're done.

Answers
Typical properties of ceramic materials include very high elastic modulus, very high melting temperature, excellent strength in tension (poor in compression), and very high hardness.
Ceramic materials are known for their unique set of properties. They have a very high elastic modulus, meaning they are stiff and resistant to deformation. They also have a high melting temperature, making them suitable for high-temperature applications.
Ceramics exhibit excellent strength in tension, but their strength in compression is relatively poor, often with a ratio of approximately 10:1. Additionally, ceramics are characterized by their very high hardness, making them resistant to wear and abrasion. These properties make ceramics suitable for applications such as structural components, cutting tools, and heat-resistant coatings.

Answer:
not linear
Step-by-step explanation:
a linear function contains x and y only with the exponent 1.
this allows the function to be a line (hence the term "linear"), a constant ratio of y changes to x changes for any values of x which defines linear relation between x and y.
but this equation contains a term with x², which changes the size of change of y for every value of x.
e.g. when x changes by 1 from 1 to 2, y changes by 3 from 1² to 2² (1 to 4). but if x changes again by 1 from 2 to 3, y changes by 5 from 2² to 3² (4 to 9).
this is clearly not constant.

What is Binary Search Tree?A binary search tree (BST) is a data structure used to store a set of elements in a way that allows efficient search, insertion, and deletion operations.
It is a binary tree in which each node has at most two children, called left and right children.
Here the values are 11, 41, 71, 101, 141 The given questions can be answered as follows
(a) Yes, it is possible to construct a BST where the search for x visits the sequence of key values 11, 41, 71, 101, 141.
(b) No, it is not possible to construct a BST where the search for x visits the sequence of key values 101, 141, 41, 11.
This is because in BST, the values to the left of a node are always smaller than the node's values, and the values to the right are always larger.
Therefore, if the search reaches a node with a value greater than the value of the query, it will never be reached
revisit nodes with smaller values.
(c) Yes, it is possible to construct a BST where the search for x visits the key value 1 sequence. The tree would consist of a single node with a key value of 1.
Therefore
a. Yes, there is a BST B and a query value X, so a search for X from B visits the next sequence of key values in the given order.
b. No, there is no BST B and a query value of X, so a lookup of X from B visits the next sequence of key values in the given order. c. Yes, there is a BST t and a query value x, so a search for x from t visits the next sequence of key values in the given order.

The box plots display data collected when two teachers asked their classes how many pencils they lose in a school year.
A box plot uses a number line from 5 to 47 with tick marks every one unit. The box extends from 8 to 14 on the number line. A line in the box is at 11. The lines outside the box end at 7 and 45. The graph is titled Mr. Johnson's Class, and the line is labeled Number Of Pencils.
A box plot uses a number line from 0 to 51 with tick marks every one unit. The box extends from 12 to 21 on the number line. A line in the box is at 14.5. The lines outside the box end at 0 and 50. The graph is titled Mr. Simpson's Class, and the line is labeled Number Of Pencils.
Which class lost the most pencils overall based on the data displayed?
Mr. Simpson's class; it has a larger median value 14.5 pencils
Mr. Johnson's class; it has a larger median of 11 pencils
Mr. Simpson's class; it has a narrow spread in the data
Mr. Johnson's class; it has a wide spread in the data
Answers
The class that lost the most pencils overall based on the data displayed is D. Mr. Johnson's class; it has a wide spread in the data
How to explain the informationThe answer is Mr. Johnson's class. The median is the middle value in a set of data. In Mr. Johnson's class, the median is 11 pencils. This means that half of the students in his class lost 11 or fewer pencils, and half of the students lost 11 or more pencils.
In Mr. Simpson's class, the median is 14.5 pencils. This means that half of the students in his class lost 14.5 or fewer pencils, and half of the students lost 14.5 or more pencils.
Since the median for Mr. Johnson's class is lower than the median for Mr. Simpson's class, we can conclude that Mr. Johnson's class lost more pencils overall.

Answer:
x = 19 1/3
Step-by-step explanation:
6/14 = 7/(x-3)
Using cross products
6 * (x-3) = 7*14
6x -18 = 98
Add 18 to each side
6x-18+18 =98+18
6x = 116
Divide each side by 6
6x/6 = 116/6
x =58/3
x = 19 1/3
Answer= 58/3
Step by Step
Step 1: Cross-multiply.
6*(x−3)=(7)*(14)
6x−18=98
Step 2: Add 18 to both sides.
6x−18+18=98+18
6x=116
Step 3: Divide both sides by 6.
6x /6 = 116 /6
x= 58 /3

Answer:
the student in question bought 3 large notebooks and 3 small notebooks
Step-by-step explanation:
the easiest way to explain how to do this is by recognizing that the student bought $54 worth of notebooks- which is not divisible by 10 easily. that means, we should subtract 8 from 54 until we get a number that IS divisible
54 - 8 = 46 (one small notebook)
46 - 8 = 38 (two small notebooks)
3 8 - 8 = 30 (three small notebooks)
then, divide 30 by 10 to see how many large notebook the student bought.
30/10 = 3
the student in question bought 3 large notebooks and 3 small notebooks
3. A bumblebee of mass 0.015 kg is traveling at 21.0 m/sec when it collides with a windshield. How much kinetic energy does the bee have as it hits the windshield? Show work thanks for the help
Answers
Answer:
Step-by-step explanation:
KE = (1/2) * m * v^2
where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
We are given the mass of the bumblebee as 0.015 kg and its velocity as 21.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:
KE = (1/2) * m * v^2
= (1/2) * 0.015 kg * (21.0 m/sec)^2
= (1/2) * 0.015 kg * 441.0 m^2/sec^2
= 2.92625 J
Therefore, the bumblebee has 2.92625 Joules of kinetic energy as it hits the windshield.
Answer:
The kinetic energy of the bumblebee as it hits the windshield is given by the equation KE = 0.5 x 0.015 kg x (21.0 m/s) squared. This gives us a total of 945 J of kinetic energy.

n = 4.5
Answer:
so the answer to this is n= 4.5
Step-by-step explanation:
so first because you can't subtract the one with the variable you subtract 3.7 from 3.7 and 29.8 - 3.7 that cancels the 3.7 so it looks like this
5.8n + 3.7=29.8

Source segregation involves the A. missing fundamental. B. distinction of various harmonic sounds in the broader environment. C. combination of various harmonic sounds into one. D. tuning to one particular sound. E. distinction of auditory events in the broader environment.
Answers
Source segregation refers to the ability to distinguish auditory events in the broader environment. This involves the distinction of various harmonic sounds present in the environment.
Source segregation is a perceptual process that allows individuals to separate and identify different auditory events or sources in a complex acoustic environment. It involves the ability to perceive and distinguish different sound sources based on their characteristics. This includes factors such as pitch, timbre, spatial location, and temporal properties.
The process of source segregation allows us to focus on specific sounds of interest while ignoring or separating them from other concurrent sounds. It enables us to identify and track individual sound sources in environments with multiple overlapping sounds, such as conversations in a noisy room or identifying individual instruments in a musical ensemble.

Below is a diagram of Hillcrest High School. The english and math buildings are congruent rectangles. The art building is a square. The total perimeter of Hillcrest High school’s building is 1,718 feet. Find the value of x. Find the missing perimeters for the buildings.
1. Find the value of x.
2. Find the missing perimeters for the buildings.
3. What is the area of the English building? (plug in your x value!)
Answers
Answer/Step-by-step explanation:
1. Perimeter of the building = sum of all the length of the outer borders surrounding the building = 1,718 ft
Thus:
4x - 6 + 2x + 3x + 2(3x + 4) + 3x + 2x + x + x + x + 2x + 4x - 6 + 2(3x + 4) + 4x - 6 + 3x = 1,718
Open the Parentheses
4x - 6 + 2x + 3x + 6x + 8 + 3x + 2x + x + x + x + 2x + 4x - 6 + 6x + 8 + 4x - 6 + 3x = 1,718
Combine like terms
42x - 2 = 1,718
42x = 1,718 + 2
42x = 1,720
x ≈ 41
2. Missing perimeter of Building = 2x + 2x + 4x - 6
Simplify
= 8x - 6
Plug in the value of x
= 8(41) - 6
= 322 ft
3. Area of English Building = length * width
= (4x - 6 + 2x)(3x)
Simplify
= (6x - 6)(3x)
Plug in the value of x
= (6(41) - 6)(3(41))
= (246 - 6)(123)
= (240)(123)
= 29,520 ft²

Answers
Statistics and probability play a critical role in continuous improvement projects by providing tools and methods to gather, analyze, and interpret data.
Continuous improvement projects are aimed at identifying and eliminating waste, reducing defects, improving efficiency, and increasing customer satisfaction. To achieve these goals, it is necessary to collect data and use it to make informed decisions about the process being improved.
Here are some specific ways in which statistics and probability are used in continuous improvement projects:
Data Collection: Statistics provides techniques for collecting data that are accurate, relevant, and representative of the process being studied. By collecting data over time, trends can be identified, and patterns can be discovered.
Data Analysis: Probability and statistics provide tools for analyzing data, including graphical techniques such as histograms and control charts, and numerical techniques such as descriptive statistics and regression analysis.
These techniques can help to identify the root causes of problems and quantify the impact of changes made to the process.
Hypothesis Testing: Probability and statistics provide methods for testing hypotheses about the process being studied.
For example, hypothesis testing can be used to determine whether a change made to the process has had a statistically significant impact on the output.
Process Improvement: Probability and statistics provide methods for optimizing processes, such as design of experiments (DOE) and statistical process control (SPC).
These methods can be used to identify the optimal settings for process parameters, such as temperature or pressure, that will result in the desired output.
