Answer 1

Answer:

Dilate triangle ABC with scale factor 1/3, then reflect over the line segment CD.

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

Explanation:

We're given that BC = 18 and EC = 6. In order to map ABC onto DEC, we need to have the triangles the same size. In other words, the triangles must be congruent and in the same location. One triangle will be on top of the other.

To make triangle ABC congruent to triangle DEC, we need to have BC = EC. Currently BC is 3 times longer than EC. So we need to dilate with a scale factor 1/3

Note how (1/3)*18 = 6. This scale factor will reduce segment BC so it goes from 18 units long to 6 units long. The same applies to the other segments of triangle ABC.

----------------------

After the dilation, triangle ABC is the same size and shape as triangle DEC. However, the two triangles are not in the same location. We would need point B to be at the same location of point E for the triangles to match up perfectly (point A and point C are already in their proper locations).

To move point B to E, we need to apply a reflection over the horizontal line CD. This will not move points A and C. Points on the line of reflection stay where they are.

---------------------

So to summarize, we apply a dilation with scale factor 1/3 to triangle ABC. This gets triangle ABC to the right size. Then we reflect over the line segment CD so that point B moves to point E's location.

what is the slope of the line
2x+12y-192

Answers

Answer:

-1/6

Step-by-step explanation:

To get the slope we need the equation in the form y=mx+c, and m is the slope.

2x+12y=192

12y = -2x + 192

y = -2/12 x + 16

-2/12 is the slope but this can be simplified to -1/6

7. Triangles CDE and RST are similar triangles. What is
the length of side CD in triangle CDE?
R
40 ft.
32 ft.
20 ft.
T
S

Answers

Answer:

CD = 25 ft

Step-by-step explanation:

[tex] \triangle CDE \sim \triangle RST[/tex]

[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]

(Corresponding sides of similar triangles are in proportion)

[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]

[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]

[tex]\therefore CD = 5\times 5[/tex]

[tex]\therefore CD = 25\: ft[/tex]

Answer:

CD = 25 ft

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values

[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex] ( cross- multiply )

32CD = 800 ( divide both sides by 32 )

CD = 25

Jane paid $40 for an item after she received a 20% discount. Jane's friend says this means that the original price of the item was $48. a. How do you think Jane's friend arrived at this amount?

Answers

Answer:

The discount is $8

Step-by-step explanation:

Step one

Given data

Jane paid $40 for an item after she received a 20% discount.

Required

The initial cost of the item

Now in other to check whether Jane's friend is correct, let us solve for the initiai cost as follows

Let the initial cost be x

20% of 40

20/100*40

=0.2*40= $8

Therefore the discount is $8

hence the original price is

discount+ discounted sale(amount paid)

=8+40

=$48

A density graph for all the possible speeds between 0 mph and 320 mph is in the shape of a triangle. What is the height of the triangle?

A. 0.025
B. 0.0125
C. 0.003125
D. 0.00625

Answers

The height of the triangle is 0.00625.The correct option is D

To solve this problem

A density graph must have an area under it equal to 1. The range of speeds in this problem, 320-0 = 320, is the base of the density graph, which is shaped like a triangle. By multiplying the base by half of the triangle's height, we can determine the density graph's area.

Let h represent the triangle's height. The triangle's area is then:

1 = (1/2)320h

calculating h:

h = 1 / (320/2) = 0.00625

Therefore, option D is appropriate because the triangle's height is 0.00625.

These beasts are monsters when they are not trained, and most of them are not. Most of them are not trained because they most likely don't have owners or a human to train them, sometimes even if they do, the humans do not get to train them. One reason these Komodo Dragons are beasts is because they sit in the sun all the time and if your dog is walking around and a Komodo Dragons sees it, well the dog is probably your new space in the backyard next to Mr.down the toilet; fish so that is one reason. The second reason is, if you have any plants of any thing that has some fruits or vegetables they will come and eat your fruits and vegetables just because they want to most of the time they aren't even hungry they are like alligators they will eat till the stomachs explode because they aren't hungry they just want to eat everything they see. The last reason is if you want to go fishing and you have an Komodo Dragons in your neighborhood and there is very few fish in your lake, well most likely it was the Komodo Dragons but it could be the alligators or birds, another reason is because if you have small children or are one you might not want to get into an eye to eye battle with and Komodo Dragons because they sometimes eat what they see so you might become its snack. If you come across one of these savage beasts you would want to look at it while you back up slowly until you are far enough till you know you can out run it. These beasts are as fast as an alligator so don't think that they won't catch you if you walk away with your eyes off it, it is like a situation with an alligator, you want to look at it and back up slowly till you are far enough distance till you know you can outrun it or if it is chasing you, you should run in zig zags until it tires out then run away to a safe place. A way to prevent these beasts from being in sight. A way to prevent these from being around is by calling an animal control inspection to scope out where you live and make sure there are no Komodo Dragons or tracks of them either. A way to get rid of them if there are Komodo Dragons is to call animal control and tell them to come get it, but if it is too close to you for that then you want to make loud noises and make yourself as big as you can kind of like a bear.
