Answer 1

Answer:

B

Step-by-step explanation:

the opposite angles of the quadrilateral ABDC are supplementary , that is

∠ BDC + 40° = 180° ( subtract 40° from both sides )

∠ BDC = 140°

How many ways can 8 books be arranged on a shelf? Show all of your work for full credit.

Answers

Answer:

There are 40,320 ways, in which 8 books can be arranged on a shelf.

Solution:

Here, we are to find the number of ways in which 8 books can be arranged on a shelf. The total number of books is 8 and the way of arranging books is also 8.

If one book is placed in the first place, then 7 books will be placed in front of it. If 2 books are placed in the 2nd place, then only 6 books can be placed after that book. This sequence will continue till 1 .

Permutations :

A permutation is an arrangement of objects in a definite order.

P ( n, r )= n ! / ( n - r ) !

n = total number of objects

r = number of objects selected

The number of ways to arrange 8 books on a shelf will be :

P ( n, r ) = n ! / ( n - r ) !

P ( n, r ) = 8 ! / ( 8 - 8 ) !

P ( n, r ) = 8 ! / 0 !

P ( n, r ) = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 / 1

P ( n, r ) = 40, 320

‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ~ Hence, there are 40,320 ways in which 8 books can be arranged on a shelf !

If the 3 books can't be together (but any 2 of the 3 can be) then it's 36,000 ways. If any one of the 3 books can't touch either of the other 2, it's 15,840 ways.

Explanation:

I'm not sure if the question is saying that all three books can't be together in a group (and so biology and history can be together, but biology, history and programming can't), or if the books in that group can't sit next to other books in the group (and so biology and history can't be together). Let's do it both ways - case 1 will be all three together and case 2 will be any 2 together.

Before we work this, let's first see the number of ways we can have all 8 books arranged. Order matters and so we can approach this using a permutation equation. Moreover, since we're using all the books, we'll end up with the total number being:

8 ! = 40 , 320 .

Alright let's solve this step by step:

Question 1: Find the perimeter of the baseDefinition of Perimeter: is all the side length of the shapes added up

            ⇒ Perimeter = 6 + 6 + 6 + 6 + 6 + 6 + 11 + 11 = 58 km

Question 2: Height of PrismDefinition of height: is the distance from the base of the figure to the top base of the figure

            ⇒ Height = 4.3km

Question 3: Lateral AreaDefinition of Lateral Area: area of nonbase face only

        ⇒ area of the two rectangles on the narrower side of the figure

            ⇒ plus the area of the pentagon on the wider side of the figure

Area of Pentagon

                 = [tex]\frac{1}{2}(base1+base2)*height = \frac{1}{2} *(6 + 11) *4.3=36.55km^2[/tex]

Area of Rectangle = 6 * 5 = 30 km^2

   Total Area = 36.55 + 36.55 + 30 +30 = 133.1 km^2

Question 4: Find the area of the base

    Area of the two bases = 6 * 6 + 6 * 11 = 36 + 66 = 102 km^2

Question 5: Find the surface area of the figureDefinition of the Surface Area: it is a measure of the total area that the surface of the object occupies

     ⇒ Surface Area = Lateral Area + Base area = 133.1 + 102 = 205.1 km^2

The missing angle of the right triangle ABC has a measure of 30°. (Correct answer: A)

How to find a missing angle by triangle properties

Triangles are geometrical figures formed by three sides and whose sum of internal angles equals 180°. There are two kind of triangles existing in this question: (i) Right triangles, (ii) Isosceles triangles.

Right triangles are triangles which one of its angles equals 90° and isosceles triangles are triangles which two of its sides have equal measures.

According to the statement, we know that triangle BQR is an isosceles triangle, whereas triangles ABC, ANB and NBC are right triangles. Based on the figure attached below, we have the following system of linear equations based on right triangles ABC and NBC:

2 · x + 90 + θ = 180   (1)

(90 - x) + 90 + θ = 180   (2)

By equalizing (1) and (2) we solve the system for x:

2 · x = 90 - x

3 · x = 90

x = 30

And by (1) we solve the system for θ:

θ = 180 - 2 · x - 90

θ = 30

The missing angle of the right triangle ABC has a measure of 30°. (Correct answer: A) [tex]\blacksquare[/tex]

The radius of the circle is the distance from the centre of the circle to the outer curve of the circle. The diameter of the circle is the length of the two points between the curve of the circle passing through the centre of the circle.

The radius of the circle is half of the diameter of the circle. The trampoline's radius will be calculated as,

Radius = Diameter / 2

Radius = ( 2 ) / 2
