Based on the information given, the value of the area of the irregular figure will be 13.7 ft².
<h3>How to calculate the area.</h3>
From the complete question, the area of a triangle will be:
= 0.5 x base x height
= 0.5 x 3.6 x 4.8
= 8.64 ft²
Area of the semicircle = 0.5πr²
Area of the semicircle = 0.5 x 3.14 x 1.8²
Area of the semicircle = 5.09 ft²
Area of the irregular figure = Area of the semicircle + Area of the triangle
= 5.09 ft² + 8.64 ft²
= 13.73ft² = 13.7 ft²

Answer:
Key points. A public good has two key characteristics: it is nonexcludable and nonrivalrous. These characteristics make it difficult for market producers to sell the good to individual consumers. Nonexcludable means that it is costly or impossible for one user to exclude others from using a good.
Explanation:
0.60 × collection = 27 cars
collection = 27 cars / 0.60 . . . . divide by the coefficient of the variable
collection = 45 cars
Samuel has 45 cars in his collection.
What is the rest of the question
The correct answer is D. Have other scientists repeat the procedure and obtain the same results.
Explanation:
One of the most accurate ways to validate the results of an experiment is to allow peers (other scientists) to review the experiment and repeat it, which is known as replication. This process is required to make sure the results are accurate because if the experiment is repeated by a different scientist and the results are different this shows the data is not consistent and therefore the results are invalid. Moreover, inconsistency or lack of replication can occur due to incorrect processes or bias by the scientist.
According to this, the next step in this situation is to "have other scientists repeat the procedure and obtain the same results".On the other hand, repeating the experiment but changing one of the variables or the procedures is not a correct step because this will change the essence of the experiment and lead to different results.
