How do I calculate the linear scale factor for this dilation?

Answer:

y=1, x=2

Step-by-step explanation:

x+y=3

x-y=1

Using elimination method

x-x+y--y=3-1

2y= 2

y=1

Substitute y=1 into equation 2

x-1=1

x=1+1

x=2

Answer:

x=1!y=2 submitted that values in question u got answers see please likable

Answer:

0.1%

Step-by-step explanation:

138 into a percent=1.38%

156 into a percent=1.56%

175 into a percent=1.75%

1.38-1.56=0.18

1.56-1.75=0.19

0.19-0.18= 0.1%

The increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

The percentage can be defined as a relative value that represents the hundredth part of any quantity.

Given that the number of volunteers in a program during year 1, year 2 and year 3 are 138, 156 and 175 respectively.

The percentage of increase in volunteers from year 1 to year 2 is given below.

Volunteers (%) = [tex]\dfrac {156-138}{138} \times 100[/tex]

Volunteers (%) = 13.04%

The percentage of increase in volunteers from year 1 to year 3 is given below.

Volunteers (%) = [tex]\dfrac {175-138}{138} \times 100[/tex]

Volunteers (%) = 26.81 %

Hence we can conclude the increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

Answer: 311 bears

Step-by-step explanation:

Population increased by 115% in the 35 years from 1970 to 2005.

Population in 2005 is:

= 270 * 115/100

= 310.5

= 311 bears

Answer:

581

Step-by-step explanation:

270x%115=310.5

We have to round 310.5 to the nearest So 310.5 will be 311  

So if it increased by 115%  we have to add the 115% to 270

270+311= 581  

By the 2005 the population will be 581

16 < n < 40

Step-by-step explanation:

use triangle inequality theorem:

n = length of third side

12 + 28 > n;    n > 40

12 + n > 28;    n > 16

n + 28 > 12  (this inequality can be discounted because it results in a negative)

Step-by-step explanation:

A heptagon is a polygon with 7 triangles. (a)

Thus, The area (A) will be = 7a

[tex]The \ area \ of \ \ triangle \ = (1/2) \times b \times h[/tex]

where;

b = base

h = height

So;

[tex]7a = \dfrac{1}{2}(bh)[/tex]

where;

b = 22.15 unit and h = 23 unit

∴

[tex]A = \dfrac{7 \times b \times h}{2} \\ \\ A = \dfrac{7 \times 22.15 \times 23}{2} \\ \\ A = 1783.07 \ sq. units \\ \\ A \simeq 1783 \ sq. units \\ \\[/tex]

Answer:

  9.  not possible

  13, 14, 19.  AAS — 13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF

  15, 16.  not possible

Step-by-step explanation:

9. You're looking for three sides, or two sides flanking a congruent angle. Here, the angle is not between the two sides, so the SAS theorem does not apply. Proving congruence is not possible.

__

13, 14, 19. You have two adjacent angles, followed by a side, so the AAS theorem will prove congruence.  

When you write the congruence statement, you need to make sure the nodes are named in corresponding order. It can be useful to name the nodes in the same order as the elements you claim for congruence. For these, we name the two angle nodes first, then the other end of the side.

13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF

__

15, 16. With only one angle and one side, it is not possible to prove congruence.

_____

Additional comment

With these theorems, you are looking for angles or sides that are adjacent (next to each other). In figure 9, there are two sides and an angle, so you might be tempted to claim SAS congruence. The name SAS means the angle must be between the two sides. In that figure, the two sides are adjacent, and the angle is adjacent to only one of the sides (not between them). Hence SAS does not apply.

(You will find later that two sides and a non-adjacent angle will define a unique triangle if, and only if, the angle is opposite the longest of the two given sides. In figures like these, no side lengths are given, and you are not allowed to rely on appearances.)

Answer:

Angle Bisector.

Step-by-step explanation:

Okay.

SU is the line across the triangle.

It isn't perpendicular because it will meet the lines eventually.

Median is a number.

I believe It's the Angle Bisector, but i'm going off of a gut feeling.
