The answer for the completion exercise shown in the image attached above is:
 1) Multilplication property of equality (If you multiply mEFG+mGDE=360° both sides of the equation by 1/2, you obtain 1/2(mEFG)+1/2(mGDE)=180°).
 2) m∠D=1/2(mEFG)
 3) m∠F=1/2(mGDE)
 4) By the substitution property of equality (Because if you substitute m∠D=1/2(mEFG) and m∠F=1/2(mGDE) into 1/2(mEFG)+1/2(mGDE)=180°, you obtain: m∠D+m∠F=280°).

In how many ways can 5 different novels, 4 different mathematics books, and 1 biology book be arranged on a bookshelf if: (a) Th
Zinaida [17]

Answer:

(a) 3628800 ways

(b) 17280 ways

(c) 120960 ways

Step-by-step explanation:

Given

Novels = 5

Maths = 4

Biology = 1

Total = 10

Solving (a): Arrangement with no restriction.

We simply count each book with no restriction. i.e. 10 books

So, the number of arrangement is:

Arrangement =10!

Arrangement =10*9*8*7*6*5*4*3*2*1

Arrangement =3628800

Solving (b): Maths book together and Novels together

First, arrange the 4 maths books as:

Maths = 4!

Next, arrange the 5 novels as:

Novels = 5!

Lastly, take the 4 maths book as [1], the 5 novels as [1] and the remaining [1] biology book.

So, we have: 3 books

Arrange 3 books, we have:

Books = 3!

Total arrangement is:

Total = 4! * 5! * 3!

Total = 4*3*2*1 * 5*4*3*2*1 * 3*2*1

Total = 17280

Solving (c): Maths book together

First, arrange the 4 maths books as:

Maths = 4!

Next, take the 4 maths book as [1], then the remaining 6 books (i.e. 5 novels and 1 biology)

So, we have: 7 books

Arrange 7 books, we have:

Books = 7!

Total arrangement is:

Total = 4! * 7!

Total = 4*3*2*1 * 7*6*5*4*3*2*1

Total = 120960

Simplify the following expression 7-5/6x7-7/6
kobusy [5.1K]

Answer:

0

Step-by-step explanation:

It is essential that you use parentheses to eliminate ambiguity here.

I will make the assumption that you meant  7-(5/6)*7-7/6.  This simplifies to

7 - 35/6 - 7/6, or

42     35      7

---- - ----- - ------ = 0

 6      6        6
