The blue figure is a dilation image of the black figure. The origin is the center of dilation. Tell whether the dilation is an enlargement or a reduction. Then find the scale factor of the dilation.

Answers

Answer: Reduction, 1/5

Because the image is smaller than the pre-image, it would be a reduction. Then you would count the length of one side of the Images. The length of the pre-image is 20 and the new image is 4. Then you would make a ratio of the new image to the pre-image which is 4/20, which simplifies to 1/5.

Hope this helps!

The scale factor of the dilation will be 1/4.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Now,

Since, The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Here, The length of black figure = 16 units

And, The length of blue figure = 4 units

So, The scale factor of the dilation = 4/16

                                                      = 1/4

A net of a triangular prism is shown below. What is the surface area, in square feet, of the triangular prism​

Answers

Answer:

[tex]Area = 152cm^2[/tex]

Step-by-step explanation:

Given

See attachment for the prism net

Required

Calculate the area

First, calculate the area of the two congruent triangle:

[tex]A_1 =2 * \frac{1}{2} * base * height[/tex]

Where

base = 6cm\ height = 4cm

So:

[tex]A_1 =2 * \frac{1}{2} * 6cm * 4cm[/tex]

[tex]A_1 =24cm^2[/tex]

Calculate the area of the middle rectangle

[tex]A_2 = Length * Width[/tex]

[tex]A_2 = 6cm * 8cm[/tex]

[tex]A_2 = 48cm^2[/tex]

Lastly, the area of the two congruent rectangles on both sides of the middle rectangle

[tex]A_3 = 2 * Length *Width[/tex]

[tex]A_3 = 2 * 8cm * 5cm[/tex]

[tex]A_3 = 80cm^2[/tex]

So, the surface area of the net is:

[tex]Area = A_1 + A_2 + A_3[/tex]

[tex]Area = 24cm^2 + 48cm^2 + 80cm^2[/tex]

[tex]Area = 152cm^2[/tex]

An airplane company wants to make a model of an 87 foot airplane. The scale they are using is 2in=8ft. How many inches long with the model airplane be?

Question 2 options:

16 inches


21.75 inches


2 inches


10.875 inces

Answers

Answer:

B. 21.75 in

Step-by-step explanation:

The length of the airplane = 87 feet

The scale  

2in = 8ft ⇒ 1 ft = 2/8 in ⇒ 1 ft = 1/4 in

The length of the model:

87*1/4 in = 21 3/4 in = 21.75 in

Answer:

No, those three sides do not make up a right triangle.

Step-by-step explanation:

Remark

The three sides will be related by a^2 + b^2 = c^2

Givens

a = 60

b = 63

c = 88

Solution

a^2 + b^2 = c^2

60^2 + 63^2 = 88^2

I would say no.

88^2 ends in a 4. 63^2 ends in a 93600 ends in a 00 + 9 <> 4

3600 + 3969 = 7569

88^2 = 7744

Finding perimeter and area.

Answers

Answer:

1. P = 14cm; A = 10cm^2

2. P = 24cm; A = 12cm^2

3. P = 32cm; A = 63cm^2

4. P = 36cm; A = 80cm^2

5. P = 32cm; A = 60cm^2

6. P = 36cm; A = 81cm^2

7. P = 26cm: A = 30cm^2

8. P = 28cm; A = 49cm^2

9. P = 26cm: A = 42cm^2

Step-by-step explanation:

Formula to find perimeter for a rectangle:

length + width + length + width

l + w + l + w

Formula to find area for a rectangle:

length × width

l × w

1.

Perimeter (P): 5 + 2 + 5 + 2 = 14

Area (A): 5 × 2 = 10

2.

P: 6 + 2 + 6 + 2 = 24

A: 6 × 2 = 12

3.

P: 7 + 9 + 7 + 9 = 32

A: 7 × 9 = 63

4.

P: 10 + 8 + 10 + 8 = 36

A: 10 × 8 = 80

5.

P: 10 + 6 + 10 + 6 = 32

A: 10 × 6 = 60

6.

P: 9 + 9 + 9 + 9 = 36

A: 9 × 9 = 81

7.

P: 10 + 3 + 10 + 3 = 26

A: 10 × 3 = 30

8.

P: 7 + 7 + 7 + 7 = 28

A: 7 × 7 = 49

9.

P: 6 + 7 + 6 + 7 = 26

A: 6 × 7 = 42

Area will always have its units squared (cm^2) because the formula requires we multiply the numbers and therefore the units: cm × cm = cm^2
