Answer: SAS theorem :-D BREH

Step-by-step explanation:

Answer:

The scale factor is 1/4

Step-by-step explanation:

Here, we are interested in finding the scale factor that helped convert the first point to the second.

Hence, what turned (8,12) to (2,3)

What we shall do here is to simply divide term 2 by term i.e

That would be 2/8 or 3/12 = 1/4

The scale factor was 1/4.

Given that,

The point (8, 12) was dilated to become point (2, 3).

We have to determine,

What was the scale factor?

According to the question,

Scale factors are closely related to the concepts of ratio and proportions.

In ratio and proportions, we multiply or divide a given amount to form a new quantity.

The point (8, 12) was dilated to become point (2, 3).

Therefore,

The scale factor was,

[tex]\rm Scale\ factor = \dfrac{New \ point \ lies \ on \ axis}{Old \ point \ lies \ on \ axis}[/tex]

Substitute the points in the formula for the x-axis,

[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ x-axis}{Old \ point \ lies \ on \ x-axis}\\\\Scale\ factor = \dfrac{2}{8}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]

And substitute the points in the formula for the y-axis,

[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ y-axis}{Old \ point \ lies \ on \ y-axis}\\\\Scale\ factor = \dfrac{3}{12}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]

Hence, The scale factor was 1/4.

Answer:

5 less than triple the quotient of a number x and 7 is 3(x ÷ 7) - 5

Answer:

The answer is 20 hours

Step-by-step explanation:

This is becuase 1280 divided by 64 equals 20.  There are no unit coversions.

In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Given that,
A car travels a distance of 1280 meters at an average speed of 64 kilometers per hour.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Time  = distance/speed
Time. t = 1.280 / 64

t = 0.02 hours

Thus, In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Answer:

Reflection - Yes

Rotation - Yes

Translation - Yes

Step-by-step explanation:

After all 3 different transformations, the angle measures of the triangle will stay the same, at 45, 45, and 90 degrees.

This is because these 3 transformations do not change the shape of the triangle. They only change the orientation and placement of the triangle.

So, the angle measures will still be 45, 45, and 90 degrees after each transformation.

Answer:

Yes, the correct answer to this question is Yes.

Step-by-step explanation:

if Figure ABCDE was reflected across the line y = x to create figure A'B'C'D'E' then (6, -2)  are the coordinates of the pre-image of E'.

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

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

It's a common type of problem in algebra, specifically the modification of algebraic equations.

ABCDE was reflected across the line y = x to create figure A'B'C'D'E'.

The coordinates of the pre-image of E' are (6, -2)

Hence, coordinates of the pre-image of E' are (6, -2)

Answer:

Step-by-step explanation:

We are to choose all the equation that evaluates b to be 11. The following equations are true;

77 = 7b

To get b, we will divide both sides by 7

77/7 = 7b/7

11 = b

b = 11

This shows that the equation is correct since b = 11

Also 9 = b-2

To get b, we will add 2 to both sides of the expression

9+2 = b-2+2

11 = b

b = 11

This shows that the equation is correct since b = 11

Hence option C and D are correct

Given :

A company currently has an advertisement that covers a bill board that is 30 ft wide by 70 ft high. The company wants to reduce the same advertisement to fit on a new billboard that is 25 ft wide by 40 ft high.

To Find :

The dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement.

Solution :

Area of original bill board :

[tex]A_i=30\times 70 = 2100\ ft^2[/tex]

Area of new bill board :

[tex]A_f=25\times 40 = 1000\ ft^2[/tex]

Since, new bill board can be completely fitted in original bill board as its length and breadth both are smaller than that.

So, the dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement is equal to 1000 ft².

Hence, this is the required solution.

Answer:

x = 3, y = 3, z = - 2

Step-by-step explanation:

Given the 3 equations

x - y - 2z = 4 → (1)

- x + 3y - z = 8 → (2)

- 2x - y - 4z = - 1 → (3)

Add (1) and (2) term by term to eliminate x

2y - 3z = 12 → (4)

Multiply (1) by 2 and add to (3) to eliminate x

2x - 2y - 4z = 8 → (5)

Add (3) and (5) term by term to eliminate x

- 3y - 8z = 7 → (6)

Multiply (4) by 3 and (6) by 2

6y - 9z = 36 → (7)

- 6y - 16z = 14 → (8)

Add (7) and (8) term by term to eliminate y

- 25z = 50 ( divide both sides by - 25 )

z = - 2

Substitute z = - 2 into (7)

6y + 18 = 36 ( subtract 18 from both sides )

6y = 18 ( divide both sides by 6 )

y = 3

Substitute y = 3 and z = - 2 into (1)

x - 3 + 4 = 4

x + 1 = 4 ( subtract 1 from both sides )

x = 3

Solution is x = 3, y = 3, z = - 2

Number of water bottles bought by Sylvia = 24

Number of water bottles sold by Sylvia = [tex]x[/tex]

Number of water bottles left with Sylvia = [tex]24-x[/tex]

Number of water bottles bought by Sam = 36

Number of water bottles sold by Sam = Three times as many as bottles as Sylvia sold = [tex]3x[/tex]

Number of water bottles left with Sam = [tex]36-3x[/tex]

It is given that the number of water bottles left with Sylvia and Sam are equal.

i.e.

Answer:

C

Step-by-step explanation:

This might look strange, but I would begin by adding 4y to both sides.

12x = 20 + 4y          Subtract 20

12x - 20 = 4y           Divide both sides by 4

12x/4 - 20/4 = 4y/4 Combine

3x - 5 = y
