Step-by-step explanation:
The original cost of a Tesla at the highest end of cost was $120,000. The new model of 2021 is set to cost around $50,000. What is the approximate percent decrease rounded to the nearest whole?
Answer:
58%
Step-by-step explanation:
it went down by 70000, so the percent of decrease is 58.3333, which is 58% rounded

Answer:
-Why is Democritus important with regard to atomic theory? Democritus developed his atomic philosophy as a middle ground between two opposing Greek theories about reality and the illusion of change. He argued that matter was subdivided into indivisible and immutable particles that created the appearance of change when they joined and separated from others.
-Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
-What subatomic particle did JJ Thomson discover? He discovered the electron in 1897.
-In 1913, Neils Bohr proposed a new atomic model known as the Bohr's model, which is patterned after the solar system.
- List the principles of Bohr's model:
a. An electron moves around the nucleus in a circular orbit.
b. An electron's angular momentum in the orbit is quantisized.
c. The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon.
- In 1926, Erwin Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This model is known as the Rutherford Model of an atom.
-In 1932, James Chadwick discovered the neutron.
-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called quarks. The quarks themselves are in turn made of vibrating strings of energy.
-Everything in the universe (except energy) is made up of matter.
-Therefore everything in the universe is made up of atoms.
-An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons and electrons.
The protons and the neutrons make up the centre called the nucleus.
The electrons fly around above the nucleus in a small cloud.
The electrons carry a negative charge and the protons carry a positive charge.
In a normal (neutral) atom the number of protons is the same number of electrons.

a. 12 books/hour
b. 1 1/3 books/hour
c. 1/12 books/hour
d. 3/4 book/hour
Answer:
The Answer would be D. 3/4 Book/Hour
Step-by-step explanation:
You would flip 1/3 to 3/1 which makes it a whole number. Then multiply 1/4 and 3.
1/4 x 3 which gives you 3/4.
Hence, your answer is 3/4

Brittany and Will each made a triangular sign with an area of 8 square feet. The base of Brittany's triangle is half as long as the base of Will's. How do the heights of the triangles compare?
Answer:
the length of Brittany's triangular sign is 1/2 the length of Will's
Step-by-step explanation:
The height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).
How do the heights of the triangles compare?Let's assume the height of Brittany's triangle is h₁ and the height of Will's triangle is h₂.
For Brittany's triangle:
A = ¹/₂b₁h₁ = 8
For Will's triangle:
A = /₂b₂h₂ = 8
We are also given that the base of Brittany's triangle is half as long as the base of Will's triangle
b₁ = ¹/₂b₂
Now, let's find the relationship between the heights of the triangles:
From the equations above, we can see that:
h₁ = 16 / b₁
h₂ = 16 / b₂
Recall; b₁ = ¹/₂b₂
h₁ = (2 x 16) / b₂
h₂ = 16 / b₂
So, the height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

Explain what features of the graph make it misleading.
Describe what people seeing the graph might misinterpret because of the misleading features.
Design a new version of the graph changing the misleading features so that the graph is no longer misleading. Use the same data provided in the original graph
Describe the corrections you made and why you made them.
Write a short paragraph – at least 3 sentences – explaining why people need to examine graphs closely and what features to look for so they can identify misleading graphs.
Analysing the pie chart.
ANSWER:
Explain what features of the graph make it misleading.
This graph is highly misleading, seeing as numerical calculations don't add up to 100%, as the standard pie chart does. The numerical values of each section add up to 178% which makes this pie chart extremely hard to interpret upon first glance. (Keep this information, it'll be important!)
Describe what people seeing the graph might misinterpret because of the misleading features.
Seeing as most people look at percentages out of 100%, people may think that one section describes 68% of 100% of people who took a survey felt a certain way, when in reality, the calculations are just off. Not only are the titles of the pie chart sections extremely generic, they don't give much context to the situation, even with the title in mind.
Designing a new pie chart.
Design a new version of the graph changing the misleading features so that the graph is no longer misleading. Use the same data provided in the original graph.
EXPLANATION:
1. We will start with the title and our section names. We have three sections based on the title 'Biggest COV-19 Worries,' which we can keep. We can rename our titles in this manner:
Getting It ---> Contracting COV-19
Family Getting It ---> Relatives Contracting COV-19
The Economy ---> COV-19's Effect on US Economy
2. Now we can look at percentages. I'll give an explanation and then I'll give numerical values for your recreation of the pie chart:
Since our pie chart has a whole value of 178%, we need to convert our numerical values to 100%. (ex. 89% of 178% = 50% of 100%) We can use simple decimal/percentage conversion for this.
68% of 178% = 38.2% of 100%
62% of 178% = 34.8% of 100%
48% of 178% = 26.9% of 100%
If we round these all accordingly, we get 38%, 35%, and 27%, which all add up to 100%.
Now we can create the bar graph with the right proportions for a bar graph of our values.
ANSWER/GUIDE:
38% corresponds to 'COV-19's Effect on US Economy,' 35% to 'Relatives Contracting COV-19,' and 27% to 'Contracting COV-19.'
(There are a few websites that allow you to make pie charts with numeric values, titles, and section names. Hope you're able to use one.
With our new graph, we corrected the misleading percentages in the pie chart, the generic and bland language of the descriptions, and made the graph much easier to read and interpret.
Why things like this shouldn't happen.
Write a short paragraph -- at least 3 sentences -- explaining why people need to examine graphs closely and what features to look for so they can identify misleading graphs.
ANSWER:
Things like this cannot happen as it can lead to make wrongful assumptions or claims. Not only will this confuse someone, it simply miseducates everyone who tries to interpret the graph as written. When expressing something highly important such as the COV-19 pandemic, you want to make sure you are giving credible and reliable information. When you're making graphs such as this, you want to look for three main things:
What data has been collectedHow this data is being interpretedWhether or not the data is precise and informativeHope this helped and good luck, fellow scholar!Please hurry, i'm being timed!!!!!!

Find the distance between -2 3/5 and -1 on a number line, Write the answer as a mixed number.
Answer:
-3 3/5
Step-by-step explanation:
-1 can also be written as -1/1
the lowest common denominator is 5 so re write the as 3/5 - 5/5
-3/5 - 5/5 = -8/5 = -1 3/5
-2 - 1 3/5 = -3 3/5
The distance between the numbers -2(³/₅) and -1 will be -3³/₅.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R."
It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
The distance will be calculated as;-
-1 can also be written as -1/1 the lowest common denominator is 5 so rewrite the as 3/5 - 5/5
-3/5 - 5/5 = -8/5 = -1³/₅
-2 - 1³/₅= -3³/₅
Therefore, the distance between the numbers -2(³/₅) and -1 will be -3³/₅.
