First find the area of rectangle = 12X8 = 96
Area of circle = 3.14X4X4 = 50.24
(1/2)area of circle = 25.12

Final answer = 96 - 25.12 = 70.88

A film maker wants to make and sell DVDs of a documentary film. It costs $6500 to make the film and $1500 to set up production

algol [13]

Step-by-step explanation:

Cost to make the film : $6500

Cost to set up production: $1500

Additional cost to make each video : $4

Additional cost to make n videos : $4n

total cost to make n videos = $6500 + $1500 + $4n = (8000 + 4n) dollars

overall cost to make each video

= total cost to make n videos ÷ n videos

= (8000 + 4n) / n

by definition, in order to "break even", the selling price for each video must be equal to the cost to make each video. i.e

Price, P(n) = (8000 + 4n) / n

Hence,

P(500) = [8000 + 4 (500)] / 500 = (8000 + 2000) / 500 = $20

This means that in order to break even selling 500 DVD's he has to sell each one for $20

Asia and taryn each had the same amount of money. after asia spent $14 and taryn spent $22, the ratio of asia's money to taryn's

blagie [28]

It is given in the question that

Asia and taryn each had the same amount of money. after asia spent $14 and taryn spent $22, the ratio of asia's money to taryn's money was 4 to 3.

Let , initially, they both have $x each .

So according to the given question ,

$\frac{x-14}{x-22} = \frac{4}{3}$

Cross multiplication

$3(x-14) = 4(x-22)
\\
3x-42 = 4x-88
\\
88-42 = 4x-3x
\\
x = 46$

Therefore , initially, they both have $46 each .

Answer:

The perimeter is 16 yards.

Step-by-step explanation:

♤You can solve using the <u>pythagorean theorem</u>.

♡We will be using the variable 'x' to represent the variable 'b' in the picture provided.

◇In the pythagorean theorem, a and b represents bases while the c represents the hypotenuse (diagonal).

${a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {12}^{2} = {20}^{2} \\ {x}^{2} + 144 = 400 \\ \frac{ \: \: \: \: \: - 144 = - 144}{ {x}^{2} = \sqrt{256} } \\ x = 16$
