  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We have a right triangle. We can use PT to solve for the missing side length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 5

Leg <em>b </em>= <em>x</em>

Hypotenuse <em>c</em> = √72

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    5² + x² = (√72)²
  2. Exponents:                           25 + x² = 72
  3. Isolate <em>x</em> term:                      x² = 47
  4. Isolate <em>x</em>:                               x = √47

If the cost of manufacturing mobile phones is $10,000 for the factorytime plus $80 per phone and that each
ozzi

Answer:

500 phones

Step-by-step explanation:

cost of manufacturing: y = 80x + 10,000

money from phone sales: y = 100x

* note: x = #phones

solve for when they're equal;

100x = 80x + 10,000

100x - 80x = 80x - 80x + 10,000

20x = 10,000      –––––––––––> divide both sides by 20

x = 500
