Answer:

You would need $18 total to buy the racks needed.

Step-by-step explanation:

First, every 20 CDs needs a new rack, so you would divide 120 by 20.

120 / 20 = 6 racks

Second, you would multiply the price ($3) of a rack by how many racks needed.

3 * 6 = $18

Answer:

3^2 + x^2 = 9^2

9 + x^2 = 81

x^2 = 72

x = \sqrt{72\\}, which is about 8.5

Cosine X = 3/9

Cosine X = 1/3

angle x= 70.5

If angle x= 70.5, angle z = 19.5 degrees.

Let me know if this helps!

Write an equation to represent the function.
svet-max [94.6K]

Answer:

<u>f(x) = 50 + 25(x - 1)</u>

Step-by-step explanation:

Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:

Lifetime membership fee = $ 50

First video game is free

Then any video game purchased after = $ 25.

Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:

<u>f(x) = 50 + 25(x - 1)</u>

  • If x = 1, then f(1) = 50 + 0 = 50
  • If x = 2, then f(2) = 50 + 25 = 75
  • If x = 5, then f(5) = 50 + 100 = 150
