35 x 0.8 = 28
0.8
4/5
80'/.= 0.80
80percent
80/100 = 4/5
probably carbon
probally 80percent
0.8 x 1700 = 1360 80% of 1700 is 1360
I believe the answer is 35%. Since the formula for energy = useful work / total work input, you would then plug 35 j into the useful work and 100 under the total work input. You divide that and you get .35. Then, you multiply .35 by 100, and you get 35%.
We must remember that if the father is bald there is over 80percent chance that the son to will be bald.
35
35 x 11 = 35 + 350 = 385
