Tessa bought stock in a restaurant for $277.00. Her stock is now worth $346.25. What is the percentage increase of the value of Tessa's stock?

Answers

Answer:

125%

Step-by-step explanation:

Divide 346.25 by 277

you get 1.25

multiply it by 100

Answer:

25%

Step-by-step explanation:

This is calculated this way:

$346.25/$277 = 1.25

Then subtract 1, because that part represents what Tessa had to start with. That leaves

0.25

That decimal equals 25%, and that is the answer.

Which best describes the composition of transformations that maps ΔLMN to ΔL'M'N?

Answers

Answer:

a

Step-by-step explanation:

its A

Option C us correct, (D₂oR x-axis)(ΔLMN)  best describes the composition of transformations that maps ΔLMN to ΔL'M'N

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We have to find the composition of transformations that maps ΔLMN to ΔL'M'N.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Graph transformation is the process by which a graph is modified to give a variation of the proceeding graph.

The graphs can be translated or moved about the xy-plane.

A translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis.

As we observe the graph dilation and reflection applied to triangle LMN to get triangle L'M'N'.

A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.

(D₂oR x-axis)(ΔLMN) is the transformations that maps ΔLMN to ΔL'M'N.

Hence, Option C us correct, (D₂oR x-axis)(ΔLMN) is the transformations that maps ΔLMN to ΔL'M'N.
