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

Explanation:

Each face is a polygon representing a wall, ceiling or floor of the 3D structure. If we rotated the figure so that one triangle is flat on the ground we would have...

That's 2+3 = 5 faces total.

-----------

The edges connect adjacent faces. For instance, two neighboring walls are connected with an edge. There are 3 edges that connect adjacent walls. There are 3+3 = 6 more edges that connect a wall to either the ceiling or the floor.

That's 3+6 = 9 edges total.

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

Vertices are corner points. They are endpoints of segment edges.

The triangular floor provides 3 vertices. The triangular ceiling provides the other 3.

That's 3+3 = 6 vertices total

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

Extra info:

Euler's polyhedron formula is

F+V-E = 2

where

Let's use that formula for

So,

F+V-E = 2

5+6-9 = 2

11-9 = 2

2 = 2

The formula works for this polyhedron and any other polyhedron. So if you know two of the three items (say the value of F and V), you can use the formula to determine the missing third piece.

Answer: a=1/2bh+lw

Step-by-step explanation:

the 1/2bh works for a right-angled triangle but we have that and also part of a square or rectangle, so we added a little onto that area and boom a=1/2bh+lw is the answer.

Answer:

least value=-8, Q1=-0.5, median=3, Q3=5, greatest value=10

Step-by-step explanation:

To find the least and greatest values, we simply look at the numbers in the data set and see that the least is -8 and the greatest is 10.

To find the first quartile, median, and third quartile, we need to put the data in order from least to greatest:

-8, -5, -1, 0, 0, 1, 2, 4, 4, 5, 5, 7, 9, 10

There are 14 numbers in the data set, so the median is the average of the 7th and 8th numbers, which is:

(median) = (2+4)/2 = 3

To find the first quartile, we need to find the median of the lower half of the data set. The lower half includes the first 7 numbers:

-8, -5, -1, 0, 0, 1, 2

The median of this lower half is the average of the 3rd and 4th numbers:

(first quartile) = (-1+0)/2 = -0.5

To find the third quartile, we need to find the median of the upper half of the data set. The upper half includes the last 7 numbers:

2, 4, 4, 5, 5, 7, 9, 10

The median of this upper half is the average of the 4th and 5th numbers:

(third quartile) = (5+5)/2 = 5

So the least value is -8, the first quartile is -0.5, the median is 3, the third quartile is 5, and the greatest value is 10.

B is correct. B is rights because at the end of the equation you need to divide by 1 so it all equals out.

Answer:

Choose Choice B

Step-by-step explanation:

45-19 is 26.

All of the other equations don't make sense except B

Answer:

Quick not so accurate answer: ((15•13:)2)•50=4875m

More accurate answer: area of 1 triangle is ((15cm*15cm)*√3)/4 = (225*√3)/4 = 389.711432/4 = 97.427858cm2

to get the full hexagon multiply I by six, that is 584.567148cm2.

Then multiply that by its height that is 50cm to get the volume, that is 29228.3574cm3.

An equation that could be used to determine the number of books that Keiko bought include the following: B. 4b - 5 = 71.

The number of books is equal to 19 books.

In order to write a linear equation to describe this situation, we would assign a variable to the number of books, and then translate the word problem into a linear equation as follows:

Let the variable b represent the number of books.

Since Keiko bought some books for $4 and received a discount of $5 off of her total purchase, a linear equation that models the situation is given by this mathematical expression:

4b - 5 = 71

Next, we would calculate the number of books (b) as follows;

4b - 5 = 71

4b = 71 + 5

4b = 76

b = 76/4

b = 19 books.

Answer:

Step-by-step explanation

As you know, the angles of a triangle must have a sum of 180 degrees.

Here you got the first part correct and for the second part all you need to do is write 76.2 as the angles they gave you equal 180 degrees.

76.2 + 81.7 + 22.1 = 180

Answer: (9, -7), (9, -17), (14, -12), (4, -12)

Step-by-step explanation:

Answer:

A universal theme is an idea that applies to anyone regardless of cultural differences or geographic location. Universal themes are ways to connect ideas across all disciplines. It is a central idea about the human condition.

Step-by-step explanation:

Connect the points and find the distances. Then match them up with one of the answers till you get the right one.

We have divided the figure into 3 parts i.e. ; 2 rectangles and 1 triangle...

[tex] \boxed{ \red { \mathfrak{Area\: of\: figure =l \times b + l \times b + \frac{1}{2} \times b \times h}}}[/tex]

We have the dimensions:

[tex] \blue{ \sf{Area\: of\: figure = 8 \times 7 + 6 \times 2 + \frac{1}{2} \times 2 \times 1 }}[/tex]

[tex] \blue{ \sf{Area\: of\: figure =56 + 12 + \frac{1}{ \cancel2} \times \cancel 2 }}[/tex]

[tex] \blue{ \sf{Area\: of\: figure =56 + 12 + 1}}[/tex]

[tex] \blue{ \sf{Area\: of\: figure =69 \: {ft}^{2} }}[/tex]

Hence, Option B is correct!!
