16. A rectangle of length (4x - 1) cm and breath 2xcm has an area of 10cm2. Find
a Value of x
b. Its length and breath
c. Perimeter​

Answers

Answer 1
a) 2x(4x-1)=10

Expand

8x^2-2x=10

Divide all terms by 2

4x^2-x=5

4x^2-x-5=0

4x^2+4x-5x-5=0

4x(x+1)-5(x+1)=0

(4x-5)(x+1)=0

x is equal to -1 and 5/4

but, in this case, the side of a rectangle cannot be negative, so the only answer that is mathematically possible is 5/4

b) substitute 5/4 into given expressions

length: 4(5/4)-1 which is 4cm

width: 2*5/4 which is 2.5cm

c) plus all four sides together

2.5+2.5+4+4 which is 13cm

Recycling Essay: Recycling is one of the 3 R’s, reduce, reuse, and recycle, which aims at promoting sustainable living. Recycling refers to when we convert something which can be considered waste into a new product. For example, when you buy a plastic bottle of water, you can send it to recycling centers to be made into something like plastic bags rather than throwing it away. Recycling is one of the most important waste management practices, and it is essential to follow for sustainable living.

Long and Short Essays on Recycling for Students and Kids in English

Read below to find two essays about recycling. The first essay is a long essay of 500 words, and the second is a short essay of 200 words. The former is suitable for class 7-10 students as well as for those aspiring for competitive exams. The latter is ideal for kids of class 6 and below.

Long Recycling Essay 500 Words in English

Below we have given a long essay on recycling 500 words and is suitable for students of classes 7,8,9 and 10, and also for competitive exam aspirants.

When we take any scrap material that looks like it could go in the dustbin, and creates a whole new product or object out of it, it is called recycling. Recycling is an incredibly vital practice that we all must learn to follow. It is one of the 3 R’s, where the other two are reducing and reusing. Reducing refers to trying to reduce the amount of waste we produce, reusing refers to when we reuse something the way it is instead of throwing it away. Recycling refers to when we take the materials used to produce a good and reuse them to make another. These are three practices that we must teach in our lives whenever possible, to promote sustainable development.

Waste management is one of the biggest problems in society today. On a daily basis, the world produces close to 4 million tonnes of waste. Many of this includes waste that the world can easily harvest to recycle and make into new products, and people around the world do this. Several governments require you to separate your garbage at home into wet waste and dry waste or into waste, which is recyclable and that which is not. The most common waste items include plastic, paper, metal cans, and glass.

Plastic is recycled according to its quality and type, but the basic process is to melt it and recreate another plastic item. To recycle paper, it is first cleaned of any ink or dirt using chemicals, then made into a pulp, which is later made into new, clean paper. Objects made of glass or metal follow recycling processes similar to that of plastic, with the difference being that they are first broken and only melted into new ones.

However, we need not only depend on government regulations to begin recycling in our own homes. There are several ways in which we can practice recycling at home, and they are simpler than we may think. Plastic bottles are recyclable in many ways – you can make several lovely crafts out of them using your creativity and imagination. Glass bottles and jars are recyclable and reusable, thus if you finish a bottle of pickle or jam, you can easily reuse those bottles or jars for something else. Hence you can use the concept of recycling even to let your imagination and creativity run wild.

What is an analogy?

Analogy is a cognitive process that involves transferring knowledge or meaning from one topic to another, or it can also be expressed linguistically.

Further Problem-solving, decision-making, reasoning, perception, generalization, memory, creativity, innovation, prediction, emotion, explanation, conceptualization, and communication all rely heavily on analogies.

It lags behind fundamental tasks like place, object, and person identification, for instance in face perception and facial recognition systems. Analogy has been called "the core of cognition," according to some.  Explanation, comparisons, metaphors, similes, allegories, and parables are all examples of specific analogical language; metonymy is not included.

The receiver of a communication that includes these expressions must interpret it analogically in order to understand phrases like and so on, and the like, as if, and the mere term like.

Therefore in addition to common sense and everyday language, analogies are crucial.

Answers

Answer:

C. Their

Explanation:

Pronouns are words we use instead of nouns or noun phrases. The antecedent of a pronoun is the word it refers to. For example, in the sentence John lost his keys, the antecedent of the pronoun his is John. We used this pronoun instead of repeating John's name.

The possessive pronoun that should be used in the given sentence is their. Its antecedent is the same as the one of the pronoun everyone. Everyone is an indefinite pronoun, and in the given context, it's used to refer to every person in the narrator's group. This group probably consists of both men and women, which is another reason the pronoun their should be used.

Why do you need to know the importance of listening and speaking appropriately in dealing with different people in your community?

Answers

Communication is vitally important in today's day and age as it quite frankly determines the differences between a positive or a negative interaction. As more communication methods are being created and the world becomes a more multicultural environment, listening and speaking appropriately changes everything in a social sense. Since social aspects contributes heavily to the livability and emotional connections of humans, we must learn how to respect people's belief systems and how comfortable they are around certain subjects. We must also learn to listen and take on what the other person has to has. I'm sure you've been in a conversation where the other person was just not respecting you or listening to you, and this immediately makes you lose respect for them. This is why it is so important to learn about each other's communication styles and methods to learn and grow. For when this doesn't happen, livability and emotional connections to people, places, and environments decreases rapidly.

Answers

Answer:

Compound sentence

Explanation:

Compound sentences are sentences that consist of two or more independent clauses connected by a comma and coordinating conjunction or by a semicolon.

An independent clause is a clause that can stand alone as a sentence. Every sentence must contain a subject and predicate and express a complete thought. Independent clauses fulfill these criteria.

The given sentence consists of two independent clauses connected by a semicolon:

We should go out to eat; birthdays are special occasions.

As we can see, both of these clauses make sense if they stand alone. This leads us to the conclusion that they are independent clauses that make up a compound sentence.

What does Martin Luther King mean by brotherhood and Sisterhood?

Answers

Answer:

King expresses a similar belief in his speeches, emphasizing the brotherhood of white and black men and urging people of different races to treat each other with compassion. In “I’ve Been to the Mountaintop,” he tells his audience that “either we go up together or we go down together,” using the unity of man to explain why one’s freedom is tied to the freedom of others. Similarly, he closes “I Have a Dream” with an image that parallels Paul’s letter, describing “black men and white men, Jews and Gentiles, Protestants and Catholics” joining hands in solidarity. In a powerful expression of compassion in “Mountaintop,” King describes the men who threaten to murder him as “our sick white brothers,” insisting on classifying even his enemies as members of the brotherhood. He expresses a similar sentiment in “Selma” when he speaks of the coming era as the “day not of white men, not of black men, but of man as man.” As sister hood, i never heard much about. If this helped your welcome, if not im sorry...

Explanation:

Similar sentiments are expressed by King in his talks when he emphasizes the brotherhood of white and black men and calls for tolerance between individuals of different races. He uses the unity of man to explain why one's freedom is connected to the freedom of others in "I've Been to the Mountaintop," where he informs his audience that "either we go up together or we go down together."
