Cheat Sheet
- Speed-Distance-Time Fundamentals -
Master the core formula v = d/t to swiftly solve speed calculations practice problems; for example, a car covering 180 km in 3 h travels at 60 km/h. Use the triangle visualization popularized in physics texts (MIT OpenCourseWare) to recall which variable to isolate. Consistent practice in your math skills quiz will make this relation second nature.
- Simple Interest Formula -
Understand SI = P·r·t/100, where P is principal, r is annual rate and t is time in years, as taught by Khan Academy. For instance, investing $2,000 at 5% for 1.5 years yields SI = 2000×0.05×1.5 = $150. A handy mnemonic "PITA" (Principal, Interest, Time, Annual rate) helps you remember the order.
- Combined Work-Time Strategies -
Apply the sum of individual rates 1/A + 1/B = 1/T to tackle work time problems quiz items; if one painter finishes in 4 h and another in 6 h, together they finish in 1/(1/4+1/6)=2.4 h. This approach is endorsed by engineering problem-solving guides at Stanford University. Always convert all times to the same units before summing rates to avoid errors.
- Permutations and Arrangements -
Recall that the number of ways to arrange r objects from n is P(n,r)=n!/(n - r)!; for example, seating 3 students among 5 desks yields 5×4×3 = 60 arrangements. The factorial concept is central in arrangement problems quiz questions and is detailed in combinatorics courses at MIT. Visualize smaller cases to internalize how factorial growth accelerates choices.
- Mental Math & Time Management -
Boost your quiz speed by using estimation and rounding: compute 98×47 as (100 - 2)×47=4700 - 94=4606, a technique endorsed by cognitive research at the University of Cambridge. Practice drills under timed conditions from reputable sources like the American Mathematical Association's speed calculations practice materials. Breaking complex problems into simple chunks enhances accuracy and confidence in any math skills quiz.
