Which of these segments could be the image of segment AB after a sequence of reflections, rotations, and/or translations?

kirill115 [55]

Answer: HG, CD, and PN

Step-by-step explanation:

The only transformations that we have are:

Reflections, rotations and/or translations.

You should notice that none of these transformations are dilations/contractions. This means that the length of the segment will remain constant.

Then the possible images of AB after the sequence of transformations, are the segments that have the same length as AB.

The length of AB is 4 units.

The segments with the same length are:

HG, CD and PN

So any of those could be the image of AB after the transformations.

Answer: $4.95

20 • .30 = 6
20 - 6 = 14
14 • .075 = 1.05
14 + 1.05 = 15.05
20 - 15.05 = 4.95

When a class took a math test, 15% of the class failed, 25% made some mistakes (but didn’t fail), and 24 students got perfect sc

mart [117]

Answer:

There are 40 students in the class.

Step-by-step explanation:

We are given the following in the question:

Percentage of class that failed = 15%

Percentage of class that made mistakes but did not fail = 25%

Number of students that got perfect score = 24

Percentage of students that got perfect score =

$100\%-\text{Percentage of class that failed}-\text{Percentage of class that made mistakes but did not fail}\\= 100\%-15\%-25\%\\= 60\%$

Let x be the total number of students in the class.

Then, we can write:

$60\% \text{ of } x = 24\\60\% \times x = 24\\\\\displaystyle\frac{60}{100}\times x = 24\\\\x = 24\times \frac{100}{60}\\\\x = 40$

Thus, there are 40 students in the class.

Find the 8th term of the geometric sequence 7,−21,63,

finlep [7]

Answer:

8th term is -15309

Step-by-step explanation:

${ \boxed{ \bf{u_{n} = a( {r}^{n - 1} ) }}} \\ { \tt{u_{8} = 7( {( - 3)}^{8 - 1}) }} \\ { \tt{u_{8} = 7( - 2187)}} \\ { \tt{u _{8} = - 15309}}$

r is the common difference, r = -21/7 = -3
