Answer:

It is rigid

It is isometric

The size is preserved

Step-by-step explanation:

Given that Triangle ABC was translated to form A'B'C', then both triangles are congruent triangles.

A translation only moves the figure, preserving the size.

Because the size is preserved, it is a rigid transformation or isometric transformation.

8. Sam divided a rectangle into 8 congruent
S_A_V [24]

Sam divided a rectangle into 8 congruent rectangles that each have a area of 5 cm2. what is the area of the rectangle before it is divided?

Answer:

Area\ of\ the\ rectangle = 40\ cm^{2}

Step-by-step explanation:

Given:

Sam divided a rectangle into 8 congruent  rectangles that each have an area of 5\ cm^{2}

We need to find the area of the rectangle before Sam divided it.

The area of the rectangle before Sam divided is 8 times of the area of the congruent rectangles.

Area of the rectangle = 8\times (area\ of\ congruent\ rectangles)

Area of the congruent rectangle is 5\ cm^{2}

So the area of the rectangle is

Area of the rectangle = 8\times 5

Area of the rectangle = 40\ cm^{2}

Therefore the area of the rectangle before divided is 40\ cm^{2}

Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficie
Mashcka [7]

Answer:

309 students

Step-by-step explanation:

Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficient in math, and 512 were found to be proficient in either reading or math. How many were proficient in both reading and math?

We solve the above question using the formula below:

Where R = Proficiency in reading

M = Proficiency in maths

n ( R ∪ M) = n(R) + n ( M) - n ( R ∩ M)

n ( R ∪ M) = 512 students

n(R) = 423

n ( M) = 398

n ( R ∩ M) = ??

Hence:

512 = 423 + 398 - n ( R ∩ M)

n ( R ∩ M) = 423 + 398 - 512

= 821 - 512

= 309

The number of people proficient in both reading and math [n ( R ∩ M)] = 309 students
