[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>a</em> = 12 cm
<em>c</em> = 17 cm
<u>Step 2: Solve for </u><em><u>b</u></em>
- Substitute in variables [Pythagorean Theorem]: 12² + b² = 17²
- Evaluate exponents: 144 + b² = 289
- [Subtraction Property of Equality] Subtract 144 on both sides: b² = 145
- [Equality Property] Square root both sides: b = √145
- [√Radical] Evaluate: b = 12.0416
- Round: b ≈ 12.0
Answer: 250 total kids and 140 girls
Step-by-step explanation:
%56=girls that means %44= boys that means 110 is %44 of the number of kids is 110/44*100= 2.5*100=250kids 56%=girls that means %56 of 250 which is 140 girls
