2.5% of what is 2.21?
Varvara68 [4.7K]
 To get the answer do this: 

2.5% of what is 2.21

2.5%x = 2.21

2.5/100x = 2.21

0.025x = 2.21

divide both sides by 0.025

0.025x/0.025 = 2.21/0.025

x = 88.4

A particle decays at a rate of 0.45% annually. assume and initial amount of 300 mg. (
raketka [301]
The increase is an exponential increase in a multiplier
100%+0.45%=100.45% and as decimal 1.0045

Final Value = Initial Value × multiplier^{number of years}
Final value = 300(1.0045)^{60}
Final value = 393 mg (to the nearest whole number)

Half life = 0.5 years
Final value = 300(1.0045)^{0.5}=301 mg
