Answers

Answer 1
Answer:

Let's solve your equation step-by-step.

2a−8a=12−8a

Step 1: Simplify both sides of the equation.

2a−8a=12−8a

2a+−8a=12+−8a

(2a+−8a)=−8a+12(Combine Like Terms)

−6a=−8a+12

−6a=−8a+12

Step 2: Add 8a to both sides.

−6a+8a=−8a+12+8a

2a=12

Step 3: Divide both sides by 2.

2a

While building the pyramids, the Egyptians developed?

Answers

While building the pyramids, the Egyptians developed hieroglyphics. 

Final answer:

While constructing the pyramids, the Egyptians developed significant advancements in large-scale architecture and social organization. Architects like Imhotep revolutionized the realm of construction and design while the organization's vast construction projects led to the development of effective labor and administrative systems.

Explanation:

While building the pyramids, the Egyptians developed several significant advancements, especially in the realms of architecture and social organization. One of the first major developments was the use of stone in large-scale constructions, as evidenced by the shift from mud-brick mastabas to stone pyramids.

The innovative ideas of architects like Imhotep, who constructed the first pyramid for Pharaoh Djoser, spurred a radical transformation in Egyptian architecture. The construction of the pyramids required careful planning, resource management, and labor organization, leading to the development of sophisticated administrative systems and protocols. The construction projects are believed to have employed thousands of workers who were housed, fed, and cared for in nearby cities, suggesting a well-structured and efficient labor and resource management system.

Over time, architectural designs advanced from the original step pyramid to the more recognized smooth-sided pyramids. The Great Pyramid of Giza, built by Pharaoh Khufu, is one of the most notable, showcasing the architectural prowess, social organization, and logistic capabilities of the Ancient Egyptians. So, in summary, while building the pyramids, the Egyptians developed crucial advancements in architectural design, labor and resource management, and social organization.

What is the main difference between the two layers of the mantle?

Answers

the inner mantle is solid and super hot while the outer mantle is liquid and not as hot

UPPER MANTLE

- Lithosphere (Sial and Sima)

- Asthenosphere (Molten Rock River)

- Mesosphere

LOWER MANTLE

OUTER CORE (Liquid Iron and Nickel)

INNER CORE (Solid Iron Compounds)

When you learn the layers of the Earth there really isn't a lot to explain. It's one of those memorization things. You might be wondering how all the layers came to be. When the Earth was forming billions of years ago, the matter came together. The densest matter moved to the center of the planet. The lighter rocks remained on the surface. When everything was done, the mantle wound up being about 2/3 the mass of the planet.

Explain how to change a dilute solution

to a concentrated solution.

Answers

When dealing with a dilute solution and one needs to make it more concentrated, oneshould increase the quantity of solute.

Concentration of solution

  • Depends on the ration between the solute and the solvent.
  • If there is more solvent than solute, solution will be more diluted.

In order to make the solution more concentrated therefore, one needs to increase the ratio of the solute by increasing the amount of solute in the solution. For instance, pouring more salt into a salty water.

In conclusion, the solute needs to be increased.
