Since DC = 12, then EF also = 12.

Both AD and BC are indicated to be the same .

So AE = (24 - 12) / 2 = 12/2 = 6


Now you have a right triangle with height DE = 8 and base AE = 6


Using the Pythagorean Theorem we can now find AD:


AD = √(8^2 + 6^2)

AD = √(64 + 36)

AD =√100

AD = 10

Answer:

B.

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define function</u>

f(x) = 8x + 4

<u>Step 2: Prep</u>

  1. Rewrite:                         y = 8x + 4
  2. Swap <em>x</em> and <em>y</em>:               x = 8y + 4

<u>Step 3: Find Inverse (Solve for </u><em><u>y</u></em><u>)</u>

  1. Subtract 4 on both sides:                    x - 4 = 8y
  2. Divide both sides by 8:                       (x - 4)/8 = y
  3. Rewrite:                                                 y = (x - 4)/8
  4. Rewrite:                                                f⁻¹(x) = (x - 4)/8

Agata [3.3K]
There are 3 types of cost for this problem: the cost for the area covered by the tiles, cost for hourly labor and the sales tax.

Cost of Area = (10.5 ft)(8 ft)($4.75) = $399
Cost of Hourly Labor = ($22/h)(7.5 h) = $165
Sum = $399 + $165 = $564
Cost of tax = $564(0.08) = $45.12

Total Cost = $564 + $45.12 = <em>$609.12</em>

So, the amount of the bill is incorrect.
