Answer:

  x = 100

Step-by-step explanation:

The two marked angles are a linear pair, so their sum is 180°.

  57° +(x +23)° = 180°

  x = 100 . . . . . . . . . . . . . divide by °, subtract 80

A line goes through points (0, 3) and (6, 12). What would be the slope of this line's perpendicular bisector?
Leto [7]

Answer:

the slope of the perpendicular bisector is -2/3

Step-by-step explanation:

The slope of the line joining the two points P1(0,3), P2(6,12) is given by

m1 = (y2-y1) / (x2-x1) = (12-3) / (6-0) = 9/6 = 1.5

The slope m2 of a line perpendicular to the previous line is given by

m1*m2 = -1

solving

m2 = -1/m1 = -1/ (3/2) = -2/3

THerefore the slope of the perpendicular bisector is -2/3

a book store cost $80 a day to keep open, and it spends $15 for each book that it sells. if each book sells for $23, what is the
aalyn [17]

The break even point for this book store is 10

<em><u>Solution:</u></em>

Given that, book store cost $80 a day to keep open, and it spends $15 for each book that it sells

Cost to open the book store = $ 80

<em><u>The formula for solving the break even point (BEP) is:</u></em>

BEP = \frac{\text{Fixed cost}}{\text{Selling price - variable cost}}

Fixed Cost is the cost that remains constant whether the services provided or products sold increases or decreases

Variable Cost is the cost that varies or differs in proportion to the products or services produced, whether they increased or decreased

In this problem,

Fixed cost = $ 80

Selling price = $ 23

Variable cost = $ 15

Therefore,

BEP = \frac{80}{23-15}\\\\BEP = \frac{80}{8}\\\\BEP = 10

Thus break even point for this book store is 10

In order for the bookstore to continue its business, it should sell at least 10 books to meet its $80 cost
