If the pattern continues for an amount of time the verb would be in present tense. The present tense verb in these options is stays which would be the answer.

We could also use elimination method.

It’s not A or C because that would mean that it had already happened and based on the given context we don’t know that it already had happened.

It also isn’t b because using a verb ending with -ing wouldn’t make sense in this sentence when you read it aloud.

A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.

If m∠BAC = 22°, then m∠ABC = °.

Answers

The measure of the ∠ABC of the isosceles triangle is equal to 136°. Hence, ∠ABC=136°.

What is Isosceles triangle?

A triangle whose two sides and  their respective angles with the third side are equal is known as Isosceles triangle.

Given, Coat hanger is in the shape of a isosceles triangle which means that it has two equal sides.

Let ΔABC be the triangle where AB and BC are congruent.

In the isosceles triangle theorem, it says the angles opposite to the equal sides of a triangle are equal.

In Triangle ABC,

∠BAC=∠BCA

∠BAC=22°=∠BCA

As we know,

∠ABC+∠BAC+∠BCA=180°

∠ABC+22°+22°=180°

∠ABC+44°=180°

∠ABC=180°- 44°

∠ABC=136°

How can democracy best
be represented

Answers

Answer:

When the United States was founded, the Founders created a democratic republic, a system of government in which the power to govern comes from the people, but elected officials represent their interests. This system of government allows American citizens to participate in government in many ways.

The United States also has many different levels and branches of government that any citizen or group might approach. Many people take this as evidence that US citizens, especially as represented by competing groups, can influence government actions. Some political theorists, however, argue that this is not the case. These different opinions have sprouted three popular models of democracy: participatory, pluralist, and elite.

We can see each model of democracy in the American government today. In this article, we’ll define participatory, pluralist, and elite democracy and describe examples of each.

According to the article, how does scarcity impact financial choices for individuals?

Answers

Answer:

Making economic choices is another way of dealing with scarcity. The different ways nations make economic choices result in various economic systems. All nations must address the problems of resource scarcity, and all nations must allocate their limited resources to meet the needs of their citizens.

Explanation:

Doing the stuff rn

One of the fundamental ideas in economics is scarcity. It indicates that there is a gap between the supply and demand for an item or service. As a result, scarcity may restrict the options available to consumers, who in the end drive the economy.

What is scarcity?

According to the definition of scarcity used in economics, it "refers to the fundamental truth of existence that there are only a finite number of human and nonhuman resources, and that the best technical knowledge can be used to produce only limited maximum amounts of each economic product."

When a resource is scarce, it is either in high demand on the market or among the general public. Lack of resources to purchase goods is another aspect of scarcity. Scarcity's antithesis is abundance.

The famous definition of economics by British economist Lionel Robbins, which emphasizes scarcity:

Economics is the science that investigates how human behavior relates to limited resources with competing needs.
