Explanation

If he had worked hard, he would have passed the examination.

This sentence uses the past perfect tense to express a hypothetical situation that did not occur.

Explanation

The correct sentence is: He asked me where I was.

The word "he" is a subject pronoun, and "asked" is the verb.

Explanation

Let's start by using the information that 20% of a is equal to 80% of b. We can write this as an equation:

0.20a = 0.80b

To simplify, divide both sides by 0.20:

a = 4b

Now, we want to find a + b. We can substitute the expression for a in terms of b:

a + b = 4b + b

Combine like terms:

a + b = 5b

Now, we can express this in terms of a by substituting a = 4b:

a + b = 5(1/4)a

a + b = 1.25a

So, the correct answer is: 1.25a

Explanation

The algorithm used in Artificial Intelligence to analyze and understand natural language is Natural Language Processing (NLP).

NLP encompasses techniques and models designed to process and interpret human language data.

Explanation

Standards are the national benchmarks that outline learning expectations for students.

They define what students should know and be able to do at various stages of their education.

Explanation

Explanation

Inquiry-Based Learning encourages students to analyze information and draw conclusions.

This strategy involves exploring questions, investigating problems, and developing understanding through hands-on experiences and critical thinking.

Explanation

Since the sides are in the ratio 3:4:5, let's assume the common multiplier is x. Then, the sides can be written as 3x, 4x, and 5x.

The perimeter is the sum of all sides, so we can set up the equation:

3x + 4x + 5x = 24

Combine like terms:

12x = 24

Divide by 12:

x = 2

Now that we have the value of x, we can find the length of the longest side (5x):

5x = 5(2) = 10 cm

So, the length of the longest side is 10 cm.

Explanation

The area of a circle can be expressed in terms of its circumference C as:

A = C^2 / 4π

This is because the circumference C is related to the radius r by:

C = 2πr

And the area A is related to the radius r by:

A = πr^2

Substituting the expression for r in terms of C, we get:

A = C^2 / 4π

Explanation

The second robot developed in 1956 for problem-solving, learning, and interacting with its environment was Shakey.

Created by the Stanford Research Institute, Shakey was an early example of a robot with integrated AI capabilities.
