Answer:

The correct sequence of transformations that shows that △ABC is similar to △A′B′C′ is:

translation of 2 units left followed by a dilation with respect to the origin by a scale factor of 12.

Step-by-step explanation:

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object.

In this case, we can see that a dilation with respect to the origin by a scale factor of 12 would stretch or shrink the triangle, but would not change the angles.

Therefore, we need to apply a translation first to move the triangle into the correct position.

So, we first translate the triangle 2 units left, which does not change its shape or size, but moves it to a position where it can be more easily compared to the other triangle.

Then, we apply a dilation with respect to the origin by a scale factor of 12, which stretches or shrinks the triangle but does not change its shape.

Answer:

594 square centimeters

The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.

Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.

The shape is a combination of the rectangle and the triangle. Then the area of the shape is calculated as,

A = 1/2 x 18 x 9 + 18 x 12

A = 81 + 216

A = 297 square centimeters

The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.

Answer:

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

Answer:

18x + 6 = 2( 9x + 3 )

18x + 6 = 3( 6x + 2 )

18x + 6 = 6( 3x + 1 )

Step-by-step explanation:

Answer:

1. 2(9x+3)

2. 3(6x+2)

3. 6(3x+1)

Step-by-step explanation:

Okay so in the first one there is a 2 outside of the parentheses which means we will multiply whatever is inside of the parentheses by 2.

9x*2=18x

3*2=6

18x+6=2(9x+6)

Okay so in the second one there is a 3 outside of the parentheses which means we will multiply whatever is onside of the parentheses by 3.

6x*3=18x

2*3=6

18x+6=3(6x+2)

Okay so in the third one there is a 6 outside of the parentheses which means we will multiply whatever is inside of the parentheses by 6.

3x*6=18x

1*6=6

18x+6=6(3x=1)

4. 9

5. 10

6. A

7. 20

--Explanation--

1. The lower quartile is always the left side of the box.

2. The IQR is Quartile 1 minus Quartile 2, so you could subtract the number at the right of the box with the left.

3. The range is the highest number minus the lowest number. (The numbers that stretch out all the way til the lines stop)

4. The median is the line in the middle of the box.

5. The upper quartile is right of the box. (the vertical line)

6. The Lower Quartile Is Always Smaller Than The Upper Quartile.

7. The number all the way to the right of the number line.

Step-by-step explanation:

1. solution,

length of rectangle A(l)=3.1units

breadth of rectangle A(b)=1units

now,

area of rectangle A=l×b

=3.1units×1units

=3.1 sq units

2.solution,

length of rectangle B(l)=3.1units

breadth of rectangle B (b)=0.4units

now,

area of rectangleB=l×b

=3.1units×0.4units

=1.24 sq units

3.solution,

length=3.1units

breadth=1.4units

Answer:

1) 3.1   2) 1.24  C) 4.34

Step-by-step explanation:

Area = l(w)

Area of rectangle A:

3.1 * 1 = 3.1

Area of rectangle B:

0.4 * 3.1 = 1.24

Both rectangles put together:

First, let's add 1 to 0.4... 1.4

2.1   Subtracting a whole from a fraction

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

7.1   Subtracting a whole from a fraction

3 + 2 • k     2k + 3

—————————  =  ——————

   k           k  

8.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

       2     2 • k

  2 =  —  =  —————

       1       k  

9.1     Pull out like factors :

 2 - 2k  =   -2 • (k - 1)

10.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

-2•(k-1)

———————— • k = 0 • k

   k    

Now, on the left hand side, the  k  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

 -2  •  (k-1)  = 0

Equations which are never true:

10.2      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

10.3      Solve  :    k-1 = 0

Add  1  to both sides of the equation :

                    k = 1

Step-by-step explanation:

Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1

Given the equation expressed as

5−k+12=16

We need to find the value of "k" that will make the equation equal

Given

5−k+12=16

Collect the like terms

17 - k = 16

Subtract 17 from both sides

17 - k - 17 = 16 - 17
k = 16 - 17
k = -1

Hence the value of k that will make the equation true is -1

Answer:

[tex]\sqrt{65}[/tex]

Step-by-step explanation:

d = √(5+2)²+(0+4)²

d = √7² + 4²

d = √49+16

d = √65

Answer:

square root of 65

Step-by-step explanation:

So remember, the pythagreons theorm is A^2+B^2=C^2.

A and B are the side lengths, and C is the long, sloped line.

Lets count the side lengths, and plug them into the formula.

Line CB is 4, and counting AB, its 7. So lets plug them in:

4^2+7^2=C^2

Square the values(except for the missing one):

16+49=C^2

=

65=c^2

Now, we need to get C on its own.

To do this, we must get the square root of both sides:

[tex]\sqrt{65} =\sqrt{C^2}[/tex]

=

[tex]\sqrt{65} =C[/tex]

So C equals the square root of 65!

This is C, the third answer down(the square root of 65).
