∙ 12y agoTo find the answer to this, first divide 420 by 350, which is 1.2. Get the percent value of this by multiplying 1.2 by 100, so the percent value must be 120%. Since we are looking for percent change, subtract 100 from that to get 20%. The answer is "350 changes 20% to become 420", or "420 is 20% more than 350".

4203 = 420 x 420 x 420 = 74088000
21% of 420= 21% * 420= 0.21 * 420= 88.2
95% of 420 = 399 = 95% * 420 = 95%/100% * 420 = 0.95 * 420 = 399
35% of 420 = 35% * 420 = 0.35 * 420 = 147

38% of 420= 38% * 420= 0.38 * 420= 159.6
88% of 420= 88% * 420= 0.88 * 420= 369.6

The efficiency of the mechanical device is calculated by dividing the useful work output by the total work input, then multiplying by 100 to get a percentage. In this case, the efficiency would be (230 J / 420 J) x 100% = 54.76%.
500% of 420= 500% * 420= 5 * 420= 2,100
