Answer:

= -0.75-0.4

= -1.15

Step By Step

The simplified result of -0.75 - 0.4 is -1.15.

To simplify the expression -0.75 - 0.4

Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.

Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.

Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.

Putting it all together, we have -0 - 0.35 = -0.35.

But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.

In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.

So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).

In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.

Answer: 34

Step-by-step explanation:

therefore, the answer to "17 is 50 percent of what number?" is 34, and you can also derive that 50 percent of 34 equals 17

Answer:

34

Step-by-step explanation:

This is a fairly simple problem. If 17 is 50% of something, that means it's half of something. That means to multiply 17 times 2, and you get 34.

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:

Step-by-step explanation:

Equivalent Fractions with the LCD

8/21 = 8/21

2/7 = 6/21

Solution:

Rewriting input as fractions if necessary:

8/21, 2/7

For the denominators (21, 7) the least common multiple (LCM) is 21.

LCM(21, 7)

Therefore, the least common denominator (LCD) is 21.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

8/21 = 8/21 × 1/1 = 8/21

2/7 = 2/7 × 3/3 = 6/21
