General: Math Tmsca Study Guide

General Math is multiple choice. Use the answers to help you.

  • Combinations ($C$): Order does NOT matter.
  • Probability: $P(E) = \frac\textNumber of favorable outcomes\textTotal number of outcomes$

    • Area:

    Perimeter/Circumference:

    Surface Area (S.A.) & Volume (V):

  • Cube:
  • Cylinder:
  • Cone:
  • Sphere:

    • Pythagorean Theorem:

    Coordinate Geometry:

    Preparing for the Texas Math & Science Coaches Association (TMSCA) math contests requires targeted practice, speed, and familiarity with contest-style questions. This guide gives a concise, practical plan and resources to boost contest performance across all grade levels. General Math Tmsca Study Guide

    | Category | Formula | |----------|---------| | Area – triangle | A = ½ × b × h | | Area – circle | A = πr² | | Circumference | C = 2πr or πd | | Pythagorean theorem | a² + b² = c² | | Slope | m = (y₂ – y₁)/(x₂ – x₁) | | Distance | d = √[(x₂–x₁)² + (y₂–y₁)²] | | Midpoint | ((x₁+x₂)/2, (y₁+y₂)/2) | | Probability | P(event) = (# favorable)/(# total) | | Percent change | (new – old)/old × 100% | | Simple interest | I = Prt | | Mean | sum / count | | Volume – rectangular prism | V = l × w × h |

    The TMSCA General Math test closely follows the Texas Essential Knowledge and Skills (TEKS) but pushes slightly into early college topics. Here is the approximate percentage distribution. General Math is multiple choice
