To eliminate the fraction, multiply by 2 both sides of the equation. This gives,
                                     2A = h x (b1 + b2)
Then, divide both the left hand and the right hand side of the equation by the variable h.
                                 2A / h = b1 + b2
Next, subtract b1 from both sides,
                                (2A / h) - b1 = b2
Rearranging  the equation,
                                        b2 = (2A/h) - b1

zhuklara [117]

Answer:

For the cost from the two methods to be equal, 3,200 books have to be produced

Step-by-step explanation:

In this question, we are asked to calculate the number of books that will be produced for two methods of production having different fixed and variable costs to have the same production cost.

Since the number of books is something we do not know, let’s represent it with a variable called c.

For the first production method, the cost of production will be ; 58,881 + 8.50c

For the second production method, the cost of production will be; 18,081 + 21.25c

Now since they are said to be equal, we proceed to equate both;

58,881 + 8.5c = 18,081 + 21.25c

58,881-18,081 = 21.25c - 8.5c

40,800 = 12.75c

c = 40,800/12.75

c = 3,200 books

Find the sizes of the angles marked with a letter.<br> Why is my answer wrong?
jeyben [28]

Answer:

29.28 degrees.

Step-by-step explanation:

sin x / 16.2 = sin 49 / 25

Cross multiply:

25 sin x = 16.2 * sin 49

sin x = (16.2 * sin 49) / 25

sin x = 0.48905

x = 29.28 degrees.

What is the exact volume of the cone?
victus00 [196]
Answer:  [D]:  " 196π  in.³  "  .
_____________________________________________________
Explanation:
_____________________________________________________
Given: radius, "r", equal 7 in.
Given: height, "h", equals 4 in.

Volume:  V = Base area * h ; 

The base area of a cone is a circle:  A = π * r²  = π* (7²) = 49π .

(NOTE: Since all answer choices given are in terms of "π" ; we will leave the units in terms of "π").

V = (Based area) * h = (49π  in.) * (4 in.) = (49*4)π  in.³
   =  196π  in.³  ; which is: Answer choice: [D] .

Which statement below compares the decimals correctly? (3 points) A 0.63 &lt; 0.48 B 0.48 = 0.63 C 0.63 &gt; 0.48 D 0.48 &gt; 0.
Bad White [126]

Answer:

(c)\ 0.63 > 0.48

Step-by-step explanation:

Given

0.63 and 0.48

Required

Which compares them correctly

(a)\ 0.63 < 0.48

This is incorrect because 0.63 is greater

(b)\ 0.48 = 0.63

This is also incorrect because 0.63 is greater

(c)\ 0.63 > 0.48

This is also correct because 0.63 is greater

(d)\ 0.48 > 0.63

This is also incorrect because 0.63 is greater
