The Angle Addition Postulate states that the measure of an angle is equal to the sum of the measures of its smaller angles. In other words, if two angles are combined to form a larger angle, then the measure of the larger angle is equal to the sum of the measures of the smaller angles.

Right Angle: A right angle is an angle that measures exactly 90 degrees. It is represented by a small square symbol (∟) and is often used as a building block for many other types of angles and geometric figures.

Midpoint: The midpoint of a line segment is a point that divides the line segment into two equal parts. It is the point on the line segment that is exactly halfway between its two endpoints.

Congruent Angles: Congruent angles are angles that have the same measure or size. Two angles are considered congruent if they are equal in measure, regardless of their location or orientation in the plane. Congruent angles are represented using the symbol "≅".

137 + 8 + 10 = 155 attendees would be there in total.

They granted me a loan when I requested additional funds. He frequently altered his plans to please his clientele. To meet the unique needs of older inhabitants, new facilities are being provided.

160 of the 200 invited visitors, or 80%, responded.

90% of RSVPs indicated attendance, thus 144 persons are anticipated.

However, only 137 persons actually attended because 7 of the "yes" respondents did not show up.

Next, let's calculate the number of unexpected attendees:

50% of those who responded "no" attended = 0.5 x (160 - 144) = 8 people

1/4 of those who did not RSVP showed up = 0.25 x (200 - 160) = 10 people.

The method of initial rates is used to derive rate laws in the concept of initial rates. It measures the initial rate of reactions, so it gets its name, initial rates.

The instantaneous rate at the beginning of a reaction, or when t = 0, is known as the initial rate of the reaction.

The beginning rate is equal to the slope of the reactant concentration versus the time curve at time zero, which is negative.

Therefore, a frequent way of determining rate laws is the concept of the initial rates. The method entails determining a reaction's beginning rate, as its name suggests.

Here, in Hardy Weinberg principle, q is the frequency of the recessive allele i.e. 0.40 and that of the dominant allele(p) is 0.60.

The frequency of an allele in a population is referred to as its allele frequency. It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population.

The frequency and consistency of a gene's expression for a certain gene can be explained quantitatively by a principle. According to the underlying theory, the gene pool and allelic frequency both stay constant over time. Genetic balance is the term used to describe this process.

[tex]p + q = 1[/tex]

Where p is the frequency of the Y allele and p is the frequency of the Y allele. In the lower half of the picture, the Hardy-Weinberg analysis simulates the outcome of random mating in the absence of selection, drift, mutation, or migration (eg, in the absence of evolution).

Mahommah Baquaqua might have answered this question based on what is known about him.

Mahommah Baquaqua was an African born in the Kingdom of Futa Jallon in present-day Guinea who was enslaved and brought to the United States in the mid-19th century. As an enslaved person, he would not have had the freedom or resources to acquire the things he needed, and would have relied on his owner to provide for his basic needs.

However, if he were asked how people should get the resources they need, it is likely that he would emphasize the importance of self-sufficiency and hard work.

False. Languages are constantly evolving and changing over time. New words are created, old words fall out of use, and pronunciation, grammar, and vocabulary can all shift and evolve over time.

How languages tend to change over time?

This process of change is a natural part of the development of a language, and it is driven by a variety of factors, including social, cultural, and technological changes.

For example, new technologies have led to the creation of new words and phrases that did not exist before, such as "texting" or "streaming." Additionally, globalization and the spread of cultures and languages can also lead to changes in a language as new words and phrases are adopted from other languages.

Harlow's studies were performed by psychologist Harry Harlow in the 1950s and 60s, and they focused on the importance of social and emotional contact in the development of primates, including humans.

What is Harlow's Studies?

Harlow's most famous studies involved separating baby rhesus monkeys from their mothers and raising them with "surrogate mothers" made of either wire mesh or terry cloth.

The results of these studies showed that the baby monkeys preferred the comfort and warmth of the terry cloth mother, even when it did not provide food, over the wire mesh mother, which did provide food.

This demonstrated that social and emotional contact was more important to the monkeys' development and well-being than physical nourishment.

These findings had important implications for how children should be treated in institutionalized settings, such as orphanages and other care facilities.

Harlow's research showed that simple provision of food, shelter, and basic care was not enough to meet the emotional and social needs of young children.

Instead, it was necessary to provide them with consistent, nurturing relationships and emotional support in order to foster healthy development.

In summary, Harlow's studies emphasized the importance of social and emotional contact for healthy development and well-being, and provided important insights into how children should be treated in institutionalized settings and how early experiences can shape the development of self-confidence in adulthood.

Explanation:

Dependency theory attempts to explain the unequal development of countries in different parts of the world. It argues that the global structure of economic relations between the core and peripheral countries creates an unequal exchange of resources. Core countries control and benefit from the international economic system while periphery countries remain underdeveloped and dependent. Dependency theory argues that this unequal exchange of resources is the main cause of uneven economic development at the global scale. It further suggests that the only way to reduce these disparities is to reduce the dependence of peripheral countries on the core countries and to foster their independent economic growth.

Dependency theory is a theoretical framework that explains the uneven economic development of countries and regions in the global economy.

Dependency theory is a theoretical framework that explains the global economy's uneven economic development of countries and regions.

According to this theory, some countries' development is hampered by their reliance on other countries or regions for economic growth.

Dependency theory explains global economic disparities by arguing that developed countries in the core have exploited and continue to exploit less developed countries in the periphery, resulting in their economic underdevelopment.

According to the theory, less developed countries can only develop if they break free from their reliance on the core countries and establish their own self-sufficient economic systems.

Thus, dependency theorists argue that this unequal relationship between the core and periphery is maintained through various mechanisms, such as unequal exchange, multinational corporations, and international financial institutions.
