A tile company adds 10% spoilage when estimating floors. We have a floor that is
75 feet by 68 feet and we want to know about what the company is going to buy to
account for the spoilage. We estimate the dimensions of the room to the nearest tens
and then the 10% spoilage.

Answers

First, we need to calculate the total area of the floor without the spoilage. To do this, we'll multiply the length of the floor (75 feet) by the width of the floor (68 feet):
75 feet x 68 feet = 5050 square feet

Next, we need to calculate the spoilage by multiplying the total area by 10% (or 0.1). To do this:
5050 square feet x 0.1 = 505 square feet

So the spoilage is 505 square feet.

To account for this spoilage, the company will need to purchase an additional 505 square feet of tile.

Now since we need to estimate the dimensions of the room to the nearest tens, we can round the width and length to 70 and 80 respectively.

So the final estimate of the floor area will be 70 feet x 80 feet = 5600 square feet

So the company will have to purchase 5600 square feet of tile to cover the floor and account for the spoilage.

How do I properly maintain and care for my telescope?

Answers

A good place to store your telescope should be dry, free of dust, safe, and big enough for you to easily get it in and out. Your telescope should ideally be kept at or near the temperature outside.

How often should your telescope be cleaned?

Telescope optics should only be cleaned when absolutely necessary. If your scope's lens or mirror only has a few visible dust specks, you don't need to clean them.

Telescopes frequently outlive their owners, in contrast to the built-in obsolescence of many products in our throwaway culture. They don't cost anything to keep and require little care. With a little sound judgment on your section, a telescope will return a long period of interest. However, if your telescope is abused or neglected, it might not make it to the next New Moon.

The way and location in which a telescope is stored when not in use has the greatest impact on its lifespan. A decent stockpiling spot ought to be dry, sans dust, secure, and sufficiently enormous to get the telescope in and out without any problem.

4. Describe the characteristics of this rock that give clues about its origin. Decide whether you think this rock was found at location A, B, or C, and classify it as igneous, sedimentary, or metamorphic.

Answers

In the given scenario, the rock is most likely igneous in origin based on its coarse interlocking texture and visible crystals. It was found at location A and can be classified as an igneous rock.

To describe the characteristics of a rock that give clues about its origin, one needs to study the texture, mineralogy, and color of the rock. Based on these factors, one can decide whether the rock is igneous, sedimentary, or metamorphic in origin. A rock that is classified as igneous in origin typically has an interlocking texture of crystals that may be fine or coarse.

The color of an igneous rock is determined by the type of minerals that make up the rock. Some examples of igneous rocks include granite, basalt, and pumice.Sedimentary rocks are formed from the accumulation of sediment over time. They typically have a layered appearance and may contain fossils. The texture of a sedimentary rock depends on the size and shape of the sediment grains that make up the rock.

Examples of sedimentary rocks include sandstone, limestone, and shale. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure. They typically have a banded appearance and may contain minerals that are not present in the original rock. Examples of metamorphic rocks include marble, schist, and gneiss. In order to determine the origin of the rock in question, one must study its characteristics.

From the picture, it appears that the rock has a coarse interlocking texture with visible crystals. Based on these characteristics, the rock is most likely igneous in origin. From the surrounding landscape, it appears that the rock was found at location A. Therefore, this rock can be classified as an igneous rock that was found at location A.

If you are interested in knowing the most accurate calculation of the amount of energy released by an earthquake, which scale would you consult

Answers

Answer:

The Richter Scale.

Explanation:

The Richter scale is a measurement scale on which the energy released during an earthquake is expressed in a number, called magnitude; the higher the number, the higher the energy that was released. It's a logarithmic scale derived from the strength of the vibrations, as measured on the seismogram.  The Richter scale is the first earthquake scale that estimates the energy released by an earthquake or seaquake, as previous scales focused on the intensities felt during earthquakes in various places.

Answer:

If you are interested in knowing the most accurate calculation of the amount of energy released by an earthquake, consult the:

Moment Magnitude Scale.

Explanation:

Since Charles Richter's 1935 Richters Scale could only measure the earthquake's magnitude, modern scales have been developed to measure the energy released by earthquakes.  The more useful scale for measuring earthquakes is called the Moment Magnitude Scale.  This scale was defined by Thomas C. Hanks and Hiroo Kanamori (1979).  In addition, the moment magnitude scale provides a better idea of the earthquake's characteristics by indicating the different seismic waves.

Explain the inequalities of the division of the north and the south.

Answers

The division between the North and the South refers to the historical and socio-economic disparities that existed in the United States before and during the American Civil War (1861-1865).

These inequalities encompassed various aspects such as economy, culture, politics, and social structures. Economically, the North was characterized by industrialization, commerce, and a diverse economy that included manufacturing, trade, and finance. On the other hand, the South relied heavily on agriculture, particularly cotton plantations worked by enslaved African Americans.

The Southern economy was primarily agrarian, with limited industrialization and dependence on cash crops. This economic divide led to stark differences in social structures and attitudes. The South upheld a plantation system that was based on slavery, resulting in a hierarchical society with a small class of wealthy plantation owners and a large population of enslaved people.

In contrast, the North had a more diverse population and was home to a growing middle class, with a greater emphasis on individual freedoms and wage labor. Politically, the differences between the North and the South became pronounced as issues of slavery, states' rights and economic policies came to the forefront.

The Northern states gradually shifted towards opposing slavery and supporting abolitionist movements, while the Southern states sought to protect and expand their institution of slavery. These divisions ultimately culminated in the American Civil War, as tensions reached a breaking point. The war was fought between the industrialized, anti-slavery North (Union) and the agrarian, pro-slavery South (Confederacy).

compare and contrast the three types of expansion diffusion

Answers

The three types of expansion diffusion are contagious, hierarchical, and stimulus, which can be compared and contrasted according to their scope.

What is expansion diffusion?

It corresponds to a geographical concept that refers to how an idea, cultural aspects or innovations are spread from one region to another.

Therefore, contagious diffusion can be compared to others because it spreads quickly to a population and can be contrasted with hierarchical diffusion because it does not follow any order, such as social media.

Hierarchical diffusion, on the other hand, is spread relative to social class, that is, the highest class influences the lowest, such as luxury fashion trends.

And finally, stimulus diffusion occurs when innovation happens in a way that is adapted to the culture of a locality, being contrasted with other forms that occur without the need for techniques for this.

What is the most direct route from London to Edinburgh?

Answers

The most direct route from London to Edinburgh is typically via the A1(M) and M1 motorways, which connect the two cities.

Here's a brief description of the route:

Start by heading north from London on the A1(M), which begins at Junction 2 of the M1 motorway.

Continue on the A1(M) as it takes you past cities like Hatfield, Walwyn Garden City, Steerage, and Peterborough.

This road eventually merges with the A1 near Newark-on-Trent.

Stay on the A1 as it passes through Grantham, Newark-on-Trent, and Retford.

It then enters Yorkshire, where you'll drive through towns such as Doncaster and Postinfarct.

Near Weatherby, the A1 splits into the A1(M) and the A1.

Take the A1(M) northbound, which bypasses Leeds.

Follow the A1(M) as it leads you through North Yorkshire, passing by towns like Wetherbee, Boroughbridge, and Darlington.

As you enter County Durham, the A1(M) continues through Durham itself, eventually crossing the border into Northumberland.

In Northumberland, the A1(M) takes you through towns like Morphet and Alnico, offering picturesque countryside views along the way.

Finally, the A1(M) brings you into Scotland, where it eventually merges with the M9 near Falkirk.

From the A1(M)/M9 interchange, continue on the M9 until it connects with the A8, which leads directly to Edinburgh.

Please note that road conditions and specific routes may change over time, so it's always a good idea to consult current maps or navigation systems for the most accurate directions.

Explain the usefulness of social media in the promotion of human rights in S.A

Answers

Social media has become a powerful tool for promoting human rights globally, and its usefulness in South Africa is no exception. Here are some key ways in which social media contributes to the promotion of human rights in South Africa:

1. Awareness and Information Sharing: Social media platforms provide a vast network for spreading information about human rights violations, social injustices, and advocacy initiatives. Activists, organizations, and individuals can share news, stories, and updates, reaching a wide audience instantly. This helps raise awareness about human rights issues in South Africa and encourages public engagement.

2. Mobilization and Activism: Social media platforms enable the mobilization of individuals and communities to take action on human rights issues. Online campaigns, petitions, and events can be organized and shared widely, facilitating collective efforts and amplifying voices that demand change. Social media helps connect like-minded individuals, fostering a sense of solidarity and enabling coordinated action.

3. Accountability and Transparency: Social media platforms provide channels for documenting and sharing evidence of human rights abuses. Videos, images, and testimonials shared on social media can expose injustices and hold perpetrators accountable. The real-time nature of social media enables rapid response and reporting of human rights violations, ensuring that incidents are not easily ignored or swept under the rug.

4. Access to Global Support and Networks: Social media connects South African human rights activists with global networks and resources. It allows them to collaborate with international organizations, seek support, and gain insights from experiences and best practices worldwide. This connectivity expands the reach and impact of local efforts, facilitating cross-cultural dialogue and solidarity.

5. Amplifying Marginalized Voices: Social media platforms give a voice to marginalized communities and individuals whose stories and perspectives may be overlooked by traditional media. It allows them to share their experiences directly, challenging dominant narratives and fostering inclusion. Social media enables marginalized groups to advocate for their rights, promote representation, and push for policy changes.

In summary, social media plays a crucial role in promoting human rights in South Africa by raising awareness, mobilizing communities, holding perpetrators accountable, connecting with global networks, and amplifying marginalized voices. It empowers individuals and organizations to advocate for change and contributes to building a more inclusive and rights-conscious society.

on this map of earthquakes near japan, why do shallow earthquakes occur to the east and deeper earthquakes occur to the west

Answers

The subduction zone dips to the west which makes shallow earthquakes occur to the east and deeper earthquakes occur to the west.

A geological process called subduction occurs at convergent boundaries and recycles the oceanic lithosphere into the Earth's mantle. Where two tectonic plates meet, the heavier plate sinks beneath the second plate and into the mantle because of the convergence of their oceanic lithospheres. A "subduction zone" is the location where this process takes place.

A subduction zone is a plate tectonic boundary where two plates converge and one plate is driven beneath the other. Geohazards like volcanoes and earthquakes are the result of this process.
