Answer:
l = 6
+ 2a - 1
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width )
given A = 18
+ 6a² - 3a and w = 3a , then
3aw = 18
+ 6a² - 3a ( divide each term by 3a )
w =
+
-
= 6
+ 2a - 1
Answer: 10 ft.
Step-by-step explanation:
Given: Custom drapes are being fitted for a large circular window.
The window has an 8 ft horizontal shelf with a 2 ft brace that sits in the frame.
Since the brace is extended upward, it would go through the center of the shelf and the circle.
Then the diameter of the circle= the measurement og f horizontal shelf + measurement of brace=8+2=10 ft
Hence, the diameter of the window =10 ft.
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>

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,

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
That seems so hard, sending prayers and brain cells to you.
