Answer:
20%
Step-by-step explanation:
<u><em>Given/To Find:</em></u>
<em>A $52.50 screen door is on</em>
<em>sale for $42. Find the percent</em>
<em>of discount on the door.</em>
<u><em>Solve:</em></u>
<em>Formula: Value 1 - Value 2 ÷ Original Value × 100</em>
<em />
<em>Hence we have:</em>
<em>52.50 - 42 = 10.5</em>
<em>10.5 ÷ 52.50 = 0.20</em>
<em>0.20 × 100</em>
<em>=20%</em>
<em />
<em>Check Answer:</em>
<em>52.50 × 20% = 10.5</em>
<em>52.50 - 10.5 = 42</em>
<em>Hence, the percent of discount on the door is 20%</em>

- [Right Triangles Only]: Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to solve for the missing length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 8
Leg <em>b</em> = 8
Hypotenuse <em>c</em> = <em>x</em>
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 8² + 8² = x²
- Exponents: 64 + 64 = x²
- Add: 128 = x²
- Isolate <em>x</em>: 8√2 = x
- Rewrite: x = 8√2
