true or false dialations of an angle are congruent to the original angle​

Answers

Answer 1
True because a dilation is just a shrink nothing has changed as far a number of sides so the shapes are still congruent just different sizes
Answer 2

Answer: True

Step-by-step explanation: Dilations do not change the angle measure. All line segments are changed by the same factor, therefore the angle remains the same.

The circle below has a radius of 10 inches. Find the area of Sector A and Sector C

Answers

Answer:

area of sector A =  47.97 in²

area of sector C = 109.03 in²

Step-by-step explanation:

area of full circle = πr² = (3.14)(10²) = 314 in²

area of sector A = (55/360)(314) = 47.97 in²

area of sector C = (314/2) - 47.97 = 109.03 in²

Answer:

c = -10

Step-by-step explanation:

Divide both sides by -3

simplify

c - 1 = -11

add 1 to both sides

c - 1 + 1 = -11 + 1

simplify

c = -10

C=12, all you have to do is factor out the parenthesis and then the rest of the equation.

how to find the circumference using 3.14

Answers

Answer:

c = 2 * 3.14 * r    and     c = 3.14 * d

Step-by-step explanation:

The formulas for the circumference of a circle are

c = 2πr   and   c = πd

where r is the radius and d is the diameter

using π = 3.14

the formulas become

c = 2 * 3.14 * r    and     c = 3.14 * d

A cylinder made of lead has a height of 4 inches and a diameter of 2 inches. How heavy is the cylinder if lead weighs 0.4 pound per cubic inch? Round to the nearest tenth.

Answers

Answer:5.0

Step-by-step explanation:

The volume of a cylinder is [tex]\pi r^2h[/tex], since the radius is 1/2D, 2/2=1. Now, if [tex]\pi[/tex] is rounded to 3.14, the volume of the cylinder would be 1 x 1 x 3.14 x 4 = 12.56. Now, since there are 0.4 pound per cubic inch, 12.56 x 0.4 = 5.024. Rounded to tenth, the answer is 5.0 or 5.

The polygons in each pair are similar. Solve for x.*

Answers

Answer:

X = 6

Step-by-step explanation:

Heights is 5x

Lengths is 6x

The solution for the x is 7 as per the concepts of similar polygons.

Given that the polygons in each pair are similar.

To find the value of x, we can set up a proportion between the corresponding side lengths of the two similar polygons.

We have the following proportion:

(6x - 7) / 42 = 25 / 30

To solve this proportion, we can cross-multiply:

30(6x - 7) = 42(25)

Simplifying further, we get,

180x - 210 = 1050

Next, we isolate the variable by adding 210 to both sides of the equation:

180x = 1260

Finally, we divide both sides by 180 to solve for x:

x = 1260 / 180

Simplifying:

x = 7

Therefore, the value of x is 7.

Irina is watching a 3 hour movie on TV. The shaded part of the fraction model below represents the part of each hour that the movie is playing, and the unshaded part represents the time spent on commercials.

Answers

Answer:

3 * 5/6 = 15/6 hours

Step-by-step explanation:

From the figure attached :

The bar is divided into 6 equal parts ; with 5 of the sections being shaded and 1 left unshaded

The shaded represent the actual playing time

Unshaded portion = time spent in commercials

Using the model, the actual playing time of the movie excluding commercials :

(Shaded portion / total portion) * movie length

5 / 6 * 3 = (5*3) / 6 = 15/6

y = 2.95c + 6.85 shows the cost for Mrs. Franklin to go to a buffet with c of her grandchildren. 1. What is the y-intercept and what does it mean? 2. What is the slope and what does it mean? 3. If Mrs. Franklin paid $18.65 for the buffet, how many of her grandchildren did she take with her?

Answers

Answer:

Using the form y = m x + b where b is the y-intercept and m the slop

1.    6.85 is the y-intercept- when c = 0 the value of y will be 6.85

2. the slope here is m = 2.95   that means for every increase of 1 on the x-axis which is c the value of y increases by 2.95 (additional cost of each child)

3. If no children were to go the cost would be 6.85 (c = zero)

So she paid 18.65 - 6.85 = 11.8 for the children that went

11.8 / 2.95 = 4    so 4 of her grandchildren  attended

This is a pyramid problem so please help out

Answers

Answer:

Step-by-step explanation:

LA, Laterial Surface Area, is the lateral surface area of a pyramid. In this case, it is the sum of five triangles with base of 12cm and height that can be calculated as follow:

height^2 = 8.26^2 + 20^2 = 468.23

height = 21.64cm

LA = 5*1/2*12*21.64

= 649.2cm^2

SA, Surface Area, is the sum of LA and base area.

Base area = 5*1/2*12*8.26 = 247.8cm^2

SA = 649.2 + 247.8 =897cm^2

Volume, V = 1/3 * base area * height

= 1/3 * 247.8 * 20

= 1652cm^3

Answer:

Step-by-step explanation:

LA = 5x(1/2)x(12)xsqrt(8.26^2+20^2)

= 649.16

SA = LA + 5x(1/2)x12x8.26

= 896.96

V = 5x1/2x12x8.26x20/3

= 1652

Step-by-step explanation:

to make sure that you dont have a problem next time here is a formula

area of any polygon is the sum of all sides so 9 + 9 + 12 + 5 = 35

Answer: 66cm^2

To find the area of ABCDE, the two equations you will need are:
Rectangle = l • w
Triangle = (b • h)/2

Since rectangles are symmetrical, we can ignore the triangle for now.

Observe that the left side of the rectangle states 5 cm, and the bottom side states 12 cm. With this information we can infer that:

Area of rectangle is 12cm(5cm) = 60cm^2

Alright, now we can look at the triangle. What we’ll do is subtract 5cm from 9cm to get the height 4 cm; and we’ll subtract 9 cm from 12 cm to get the base 3 cm.

With this information, we can conclude that the area of the triangle (3cm(4cm)/2 = 6cm^2

Adding both the triangle and rectangle area together, we get 66cm^2
