Yes, xyz is a dilation of the abc .

To confirm this we have to check the ratios of the sides of both the triangles.

sides of the triangle ABC are :

AB = 5cm,

BC = 7cm,

CA = 8 cm

sides of the triangle XYZ are:

XY = 20 cm

YZ = 28 cm

ZX = 32 cm

Now the ratios of the sides of the both the triangles are :

AB/XY = 5/20 =1/4

BC/YZ = 7/28 = 1/4

CA / ZX = 8/32 = 1/4

All the sides have the same ratios of their sides so that we can say that XYZ is dilation of the ABC

Step-by-step explanation:

1 1/5 = 6/5. 6/5 x 8/8 = 48/40.

2 1/8 = 17/8. 17/8 x 5 = 85/40

:)

Answer:

D)  \(\frac{48}{40} + \frac{85}{40}\)

Step-by-step explanation:

\(1 \frac{1}{5} =5*1+1= 5+1 =6\)

\(\frac{6}{5}\)

\(2\frac{1}{8}=8*2+1=16+1 = 17\)

\(\frac{17}{8}\)

5 and 8 have a common multiple of 40

\(\frac{6}{5}\) + \(\frac{17}{8}\) = \(\frac{48}{40} + \frac{85}{40}\)

Step-by-step explanation:

Answer:

The relationship between the number of faces, vertices, and edges of a three-dimensional object is described by Euler's formula, which states that for any polyhedron (a solid object bounded by flat faces), the number of faces (F), vertices (V), and edges (E) satisfy the equation F + V - E = 2. This formula is true for any convex polyhedron, such as a cube or a regular tetrahedron.

The formula is based on the fact that every face of a polyhedron is bounded by a closed loop of edges, and each vertex is where three or more edges meet. The total number of edges is the sum of the number of edges around each face, which is equal to twice the number of faces since each edge is shared by two faces, and the number of edges meeting at each vertex, which is equal to the degree of the vertex (the number of edges meeting at the vertex).

Therefore, by knowing the number of faces, vertices, and edges of a three-dimensional object, we can determine if it is a convex polyhedron and use Euler's formula to check if the numbers are consistent with a solid shape.

Answer:

  A.  1,162.5

Step-by-step explanation:

Write the next two terms and add them up:

  S5 = 600 +300 +150 +75 +37.5 = 1162.5 . . . . matches choice A

================================================

Explanation:

{600, 300, 150, ...} is a geometric sequence starting at a = 600 and has common ratio r = 1/2 = 0.5, this means we cut each term in half to get the next term. We could do this to generate five terms and then add them up. Or we could use the formula below with n = 5

Sn = a*(1-r^n)/(1-r)

S5 = 600*(1-0.5^5)/(1-0.5)

S5 = 1,162.5

-----------

Check:

first five terms = {600, 300, 150, 75, 37.5}

S5 = sum of the first five terms

S5 = 600+300+150+75+37.5

S5 = 1,162.5

Because n = 5 is relatively small, we can quickly confirm the answer. With larger values of n, a spreadsheet is the better option.

How to get this answer:

x+y = 8 solves to y = -x+8 after isolating y. You subtract x from both sides.

Plug this into the second equation and solve for x

3x + 2y = 21

3x + 2( y ) = 21

3x + 2( -x+8 ) = 21 ... replace y with -x+8

3x - 2x + 16 = 21

x + 16 = 21

x = 21-16

x = 5

Use this to find y

y = -x+8

y = -5+8

y = 3

We have x = 5 and y = 3 pair up to get the ordered pair solution (5,3)

Answer:

Step-by-step explanation:

A) Find the figure attached. According to the figure, since line PQ is parallel to line RS, then <CBQ = <DCS (corresponding angle)

Also <BCS + <DCS = 180° (sum of angles on a straight line)

Given

<BCS = (5a+14)° and <DCS = <CBQ =(2a-9)°

Substituting this values into the formula to calculate the value of a;

(5a+14)°+(2a-9)° = 180°

5a+2a+14-9 = 180

7a+5 = 180

7a = 180-5

7a = 175

a = 175/7

a = 25°

Hence the value of a is 25°

B) From the diagram <ABQ = <BCS = 5a+14 (corresponding angle)

Substitute a = 25 into the expression

<ABQ = 5(25)+14

<ABQ  = 125+14

<ABQ = 139°

C) To get <BCR, we will use the formula;

<BCR + <BCS = 180

Given <ABQ = <BCS = 139°

<BCR = 180 - <BCS

<BCR = 180 - 139

<BCR = 41°

Answer:

Part A: 25

Part B: 139

Part C: 41

Step-by-step explanation:

5a+14+2a-9

a=25

5(25)+14

=139

under a counterclockwise rotation of 90° about the origin

a point (x, y ) → (y, - x )

Then

A (- 1, - 2 ) → (- 2, - (- 1) ) → (- 2, 1 )

B (2, - 2 ) → (- 2, - 2 )

C (1, - 4 ) → (- 4, - 1 )

The new coordinates are (d) A = (2, -1) B = (2, 2) and C = (4, 1)

From the question, we have the following parameters that can be used in our computation:

The figure,

Where, we have

A = (-1, -2)

B = (2, -2)

C = (1, -4)

The rule of 90 degrees counterclockwise is

Using the above as a guide, we have the following:

A = (2, -1)

B = (2, 2)

C = (4, 1)

Hence, the new coordinates are (d) A = (2, -1) B = (2, 2) and C = (4, 1)

(Linear pair angles)

z = 160°

Probability in that a survey of 250 people ,at most 155 people support such cuts is 0.62.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

If 60% of the population supports massive federal budget cuts.

We have to find the probability in that a survey of 250 people, at most 155 people support such cuts.

So, the probability is, 155 / 250 = 0.62

Hence, probability in that a survey of 250 people ,at most 155 people support such cuts is 0.62.

Answer:

the area of the rectangle is 35.25 square meters.

Step-by-step explanation:

To find the area of a rectangle, we multiply the length by the width.

First, we need to convert the mixed numbers to improper fractions to make the multiplication easier:

4 and 2/4 = 4 + 2/4 = 16/4 + 2/4 = 18/4

7 and 5/6 = 7 + 5/6 = 42/6 + 5/6 = 47/6

Now we can multiply the length and width:

Area = (18/4) * (47/6)

Area = (9/2) * (47/6) (canceling the common factor of 2 between 18/4 and 6 in 47/6)

Area = (9 * 47) / (2 * 6)

Area = 423/12

Area = 35.25

Therefore, the area of the rectangle is 35.25 square meters.
