You can stack the eight books on top of each other is one way. And then you can changed the order of how you stack the book 64 different ways. You can also do this vertically standing up. With the spin of the book facing in or out. You can arrange the. By height, color, alphabetically, thickness, year published... basically any individual characteristic they can have can be a way you stack a book.

Step-by-step explanation:

Element       frequency         Relative frequency  (percent)

1                     1                       1/24 =  0.042 = 4.2%

3                      2                       2/24 = 0.083  = 8.3%

4                       1                         1/24 = 0.042  = 4.2%

5                       1                          1/24 = 0.042  = 4.2%

6                       1                           1/24 = 0.042 = 4.2%

7                        2                         2/24 = 0.083 = 8.3%

8                        1                          1/24 = 0.042   = 4.2%

9                       2                           2/24 = 0.083  = 8.3%

10                       6                           6/24 = 0.25   = 25%

11                        1                            1/24 = 0.042 = 4.2%

12                           2                           2/24 = 0.083 = 8.3%

13                         2                           2/24 = 0.083 = 8.3%

14                         2                           2/24 = 0.083  = 8.3 %

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

                              24                                         1

<h3>Answer:  D)   y+3</h3>

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

Explanation:

Point A is located at (3,1). Point A' is located at (-5,4)

To move from A to A', we'll do two things:

  • Move 8 units to the left
  • Move 3 units up

The "8 units to the left" portion has us go from x to x-8

The "3 units up" part involves y becoming y+3

So that's how we get the translation rule (x,y) \to (x-8,y+3). The x-8 portion is already filled in for us. The missing part is y+3 which is the final answer (choice D).

Let's try this translation rule on point B to see if we arrive at the proper location of B'

B is at (2,6) which means

(x,y) \to (x-8,y+3)\\\\(2,6) \to (2-8,6+3)\\\\(2,6) \to (-6,9)\\\\

which matches up what the diagram shows. I'll let you verify that the rule also works for point C.

Help. This question is on Mathswatch. Please reply ASAP as this is due in tomorrow. Thanks
Vladimir79 [104]

Step-by-step explanation:

Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)

area of triangle = 1/2 x 20 x (16-7) = 90cm^2

area of rectangle = 20 x 7 = 140cm^2

total area = 90 + 140 = 230cm^2

What is the area of the right triangle 5 centimeters high with a base of 9 centimeters
seropon [69]

The area of the given right triangle is: 22.5 cm².

<h3>How to Find the Area of a Right Triangle?</h3>

The area of a right triangle with a base of "b" and an height of "h" can be determined using the following formula:

Area of triangle = 1/2bh = 1/2(base)(height).

Given that the right triangle has the following dimensions:

Height (h) = 5 cm

Base (b) = 9 cm

Area of triangle = 1/2bh = 1/2(5)(9)

Area of triangle = 1/2(45)

Area of triangle = 22.5 cm²

Thus, the area of the right triangle is: 22.5 cm².
