Answer:

I'm pretty sure A

Step-by-step explanation:

-20 divided by 5

Answer:

The answer is A, -20 divided by 5

Step-by-step explanation:

As you can see on the chart, alongside the 20 is five smaller arrows, all you need to know is that you would divide the total temparature ( 20 ) by the five smaller arrows if that makes any sense :)

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.

Answer:

4/5= 12/15 he had 3/15ths left meaning he painted 2/15th there's 1/15 left

The median is 1/5

Answer:

152%

Step-by-step explanation:

There are 50 small squares total, 25/25 are filled in for the 1st big square, and 13/25 filled in for the 2nd big square.

25/25 + 13/25 = 1.52

1.52 * 100 = 152%

Step-by-step explanation:

100/80 = 1.25 or 125%

The number which represent represents the Commutative Property of Addition will be;

⇒ 32 + 9 = 9 + 32

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expressions are,

44 + 1 = 45

44 + 1 = 45

(16 + 2) + 18 = 16 + (2 + 18)

(16 + 2) + 18 = 16 + (2 + 18)

56 + 0 = 56

56 + 0 = 56

32 + 9 = 9 + 32

Now,

We know that;

The rule of the Commutative Property of Addition is,

⇒ a + b = b + a

Hence, The correct number which represents the Commutative Property of Addition is,

⇒ 32 + 9 = 9 + 32

#SPJ2

Answer:

1A. Half jump

1B. 2/3 is half of 4/3

2. 4

Step-by-step explanation:

1A. The remainder of 2/3 is shown in the model by a half jump. It is a half jump because a full jump is 4/3.

1B. We know that the remainder represents 1/2 of the jogging loop because 2/3 is half of 4/3.

2. Convert 2 1/2 into a mixed number with the denominator as eighths. We then get 20/8 divided by 5/8. After that, we can see that 5/8 goes into 20/8 4 times. (5/8 + 5/8 + 5/8 + 5/8 = 20/8)

Answer:

90 suitcases would be expected to be misplaced

Step-by-step explanation:

Given 3/27

810 / 27 = 30

30 x 3 = 90

Answer:

90

Step-by-step explanation:

cuz 3/26=1/9

so, 1/9 of 810 is 90.

Answer:

y = 4x + (-9)

Step-by-step explanation:

You can observe that the line crosses the y-axis at -9, so that is our y-intercept.

For the slope, just take the y-intercept for example, and count how many squares the line goes up before reaching 1. In this problem you can see that the line goes 4 squares up in the time it takes to go 1 square to the right, so the slope is y over x, meaning 4 over 1, or just 4.

Answer:

The answer should be y = 4x + (-9).

Answer:3,150

Step-by-step explanation:

Well I what I did was I took 450 and then multiplied it by the number of days there are in a week which is 7 so I did 450 x 7 and got 3,150

I hope its right if not please let me know and I would be happy to check over again =)

Answer:

7/108 or .006481

Step-by-step explanation:

Answer:

not gonna lie, i don't really know but maybe it could be $3 an hr.

Step-by-step explanation:

If you look at where the 2nd dot is on the graph, its lined up with 3 & 9. So, i would say to divide the 9 & the 3 to get 3 which shows $3 per hour.

Hope this is right and it helps! :)

Answer:

1st Sentence: Write what your favorite subject to photograph is.

2nd Sentence: Why and what do you like about it.

3rd Sentence: continue explaining what you like about it.

4th Sentence: Maybe an incident or some information related to that (evidence).

5th Sentence: Show how that's important and how it stands out. Say why you like it and maybe why others should like it as well (explain what you see in this subject that makes it your favorite).

6th Sentence: Write your conclusion which could include what subject you like to photograph. Summarize what you like about it.

Step-by-step explanation:

For the conclusion, you can write something like this;

So in conclusion/To sum it all up, my favorite subject to photograph is _______ because of _________. It is a very beautiful subject (or write something like that). (And then here maybe put a reason why others should see the beauty/darkness of it or whatever you see in it). (Here insert some last thought/ lingering thought with your reader, something they can think about even after reading this but you want to make sure it's related to your topic.)

Answer:

I like to photograph old ruins. Unfortunately I live in the United States and those aren't very common here. There are a few super old structures, but not a lot. I've been through Europe and Southeast Asia, though, and enjoyed visiting things like stone circles or old temples and things like that. It's a subject I love, but don't get to see often. I wish I had more money so I could travel more and see more of them.
