To find all common multiples of numbers, you need to list all multiples of the numbers up to the maximum value: 3: 3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69 7: 7, 14, 21, 28, 35, 42 , 49, 56, 63, 70 All of the COMMON multiples of 7 and 3 are 21, 42, and 63
3:3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,72 7:7,14,21,28,35,42,49,56,63,70 The common multiples of 3 and 7 are 21,42, and 63.
The answer <span>the third rope to counterbalance Sam and Charlie is F and vectF +vectF1 +vectF2 =vect0 let's consider axis y'y </span>vectF = -F vectF 1= F1cos60 vectF 2= F2cos45 -F = -F1cos60-F2co45 so F= F1cos60+F2co45= 350x0.5+400x0.7=457.84 pounds
