Triangle is reflected across the y-axis and then dilated by a factor of centered at the origin. Which statement correctly descri
love history [14]

Answer:

  A.  The reflection preserves the side lengths and angles of triangle . The dilation preserves angles but not side lengths.

Step-by-step explanation:

Reflection is a rigid transformation. It preserves both angles and side lengths. Dilation preserves angles, but changes all lengths by the same scale factor.

<h3>Application</h3>

The described triangle was subject to reflection, which preserves angles and lengths. It was also subject to dilation, which preserves angles, but not lengths.

The appropriate description is that of choice A.

The second side of a triangular deck is 4 feet longer than the shortest side, and the third side is 4 feet shorter than twice th
xxTIMURxx [149]
We don’t know the value of the shorter side, so we will categorize it as x. Side 2 is just 4 feet longer than x, so we would add 4 on to it. Side 3 has double the x, so we would multiply it be 2 for 2x, and subtract the 4 feet from it.

Side 1: x
Side 2: x + 4
Side 3: 2x - 4

If the perimeter is 64 feet, then all of the sides have to add up to it. Therefore, first we add all of the side lengths up:

x + x + 4 + 2x - 4 = 4x.

Now we put 4x, the amount of all these sides added up, equal to the perimeter of 64.

4x = 64. Divide both sides by 4 to get x by itself.
x = 16.

Now that we know x is 16, we will substitute it in for all the side lengths’ equations.

We know that Side 1 was just x, so that will be 16. Since Side 2 was 4 more than x, we’d do 16 + 4 = 20. We substitute 16 in for x in Side 3’s equation: 2(16) - 4 = 32 - 4 = 28.

Therefore, the final lengths of all the sides are:

Side 1: 16
Side 2: 20
Side 3: 28

Katie walked ⅚ mile on Saturday. It took her 10 mins to walk ⅙ mile. She took 1 minute breaks in between each ⅙ mile. How long d
Gennadij [26K]

Answer:

it took her 54 mins to finish her walk.

Step-by-step explanation:

Given;

total distance walked by Katie, d = ⁵/₆

time taken to walk ¹/₆ mile = 10 mins

break time = 1 min

There are five ¹/₆ mile in the total distance which is ⁵/₆ miles.

Time for the first  ¹/₆ mile  = 10 mins +

                    break time = 1 min

Time for the second  ¹/₆ mile  = 10 mins +

                     break time = 1 min  

Time for the third  ¹/₆ mile  = 10 mins +

                     break time = 1 min  

Time for the fourth  ¹/₆ mile  = 10 mins +

                     break time = 1 min  

Time for the fifth  ¹/₆ mile  = 10 mins

Total time = 5 (10 mins)  + 4 (1 min)

                 = 50 mins + 4mins

                = 54 mins

Therefore, it took her 54 mins to finish her walk.
