Answer:

PR = 15

Step-by-step explanation:

PR = PQ + QR

10x - 45 = 3 + x + 6 {Combine like terms}

10x - 45 = 9 + x {Subtract 'x' from both sides}

10x - x - 45 = 9

9x - 45 = 9 {Add 45 to both sides}

9x = 9 +45

9x = 54

x = 54/9

x = 6

PR = 10x - 45

= 10*6 - 45

= 60 - 45

PR = 15

A company produces and sells CDs. There is a fixed cost of $2000 and $5 per CD manufactured. The manufacturer sells each CD for

OlgaM077 [116]

Call the production cost 'C', the revenue 'R' and the number of CDs 'n':

C=2000+5n
R=10n
By definition Profit P = R-C, therefore P=10n-2000+5n = 5n-2000.

Which equation can be used to find the length of Line segment A C? Triangle A B C is shown. Angle A C B is 90 degrees and angle

taurus [48]

Answer:

AC = 10sin(40°)

Explanation:

The diagram representing the question is shown in the attached image

Since the given triangle is a right-angled triangle, we can apply the special trig functions

These functions are as follows:

sin(θ) = opposite / hypotenuse

cos(θ) = adjacent / hypotenuse

tan(θ) = opposite / adjacent

Now, in the given diagram:

θ = 40°

AC is the side opposite to θ

AB = 10 in is the hypotenuse

Based on these givens, we will use the sin(θ) function

Therefore:

$sin(40) = \frac{AC}{10}\\ \\AC = 10sin(40)$
