Answer:
63
Step-by-step explanation:
7 x 9=63
9+9+9+9+9+9+9=63
Rest mass energy = m*c^2
Total relativistic engery = Rest mass energy + Kinetic Energy
Total relativistic engery = 5 * mc^2 + m*c^2
Total relativistic engery = 6 mc^2
Total relativistic engery =<span> 6 * 9.11 * 10^-31 * (3.0*10^8)^2</span>
Total relativistic engery = 4.92 * 10^-13 J
Answer:
Step-by-step explanation:
if there are 500 tixets and 7 prizes (1 top prize+1 second prize+5 third prize) your chances of wining are 7/500=0.014 or 1.4% chance
with a 1.4% chance of win and a 98.6% chance to loose in average you can expect to loose.
Substitute b for x and then solve for b
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
Hope it helped
