9. Given similar triangles ABC and PQR with AB = 4 and PQ = 7.
Fill in the following chart stating the scale factor, ratio of perimeters,
and ratio of areas:
Given:
Similar triangles ABC and PQR with AB = 4 and PQ = 7.
To find:
The scale factor, ratio of perimeters, and ratio of areas.
Solution:
In similar figures the scale factor is the ratio of side or image and corresponding side of original figure.
In similar triangles ABC and PQR, the scale factor is
[tex]k=\dfrac{PQ}{AB}[/tex]
[tex]k=\dfrac{7}{4}[/tex]
The scale factor of triangle ABC to triangle PQR is [tex]\dfrac{7}{4}[/tex].
The ratio of the perimeters of similar triangles is equal to the ratio of their corresponding sides.
[tex]\dfrac{\text{Perimeter of }\Delta ABC}{\text{Perimeter of }\Delta PQR}=\dfrac{AB}{PQ}[/tex]
[tex]\dfrac{\text{Perimeter of }\Delta ABC}{\text{Perimeter of }\Delta PQR}=\dfrac{4}{7}[/tex]
[tex]\dfrac{\text{Perimeter of }\Delta ABC}{\text{Perimeter of }\Delta PQR}=4:7[/tex]
The ratio of the perimeters is 4:7.
The ratio of the areas of similar triangles is equal to the ratio of squares of their corresponding sides.
[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=\dfrac{AB^2}{PQ^2}[/tex]
[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=\dfrac{4^2}{7^2}[/tex]
[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=\dfrac{16}{49}[/tex]
[tex]\dfrac{\text{Area of }\Delta ABC}{\text{Area of }\Delta PQR}=16:49[/tex]
Therefore, the ratio of the areas is 16:49.

Why slavery continued in the south althougt nothern states prohibited.
Answer:
Probably because in the south, the farmers needed help with gathering alot of crops, such as cotton. In the north, they didn't have farms, so they didn't need slaves.
At which plate boundary would you find an oceanic crust colliding with a continental?
Answer:
Subduction zones
Explanation:
When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.

Based on the illustration, which two continents provide the strongest evidence for the movement of landmasses?
Select one:
Australia and Europe.
South America and Africa.
India and South America.
Antarctica and North America.
Answer:
South America and Africa.
Explanation:
South America and Africa are the two continents which provides a strong evidence for the continental drift because their sides has a specific structure which can be fit with one another. The east coast of South America and the west coast of Africa fit together like pieces of a puzzle. The rock composition of east coast of South America and the west coast of Africa also similar which gives us a strongest evidence for the movement of big land masses away from each other that occurs with the passage of millions of years.
