What is an oblong number?
An oblong number is a composite (non-prime) number. If p and q are a factor-pair for an oblong number n, then the number n can be represented by a rectangle or oblong that is p units x q units.
10 ways of solving problems of transportation?
(1) minimize the cost of shipping m units to ndestinations or (2) maximize the profit of shipping m units to n destinations.
Show that impulse units are the same as momentum units?
Momentum is Mass * Velocity, therefore it is Kg*m/s Impulse is Force * Time, therefore it is N*sBy Newton's 2nd law, F=ma. Force(N) is equal to kg*m/s^2By substitution, (kg*m/s^2)*s = kg*m/s
What metric units are represented by points on the plotted line?
Any metric or non-metric units can be represented by points on the plotted line.
What number when it is divided by 1261 gives a perfect square?
The equation for this can be represented as: n/1261 = m2, where n is our target number and m is an integer Since there are an infinite number of integers to plug into m, there are an infinite number of perfect squares, which means there are an infinite number of solutions to n. n = m2 * 1261 The first few solutions could be: n = 1261, m = 1; (1261)/1261 = 12 = 1 n = 5044, m = 2; (5044)/1261 = 22 = 4 n = 11349, m = 3; (11349)/1261 = 32 = 9 n = 20176, m = 4; (20176)/1261 = 42 = 16 n = 31525, m = 5; (31525)/1261 = 52 = 25
