To calculate the remaining caffeine, we use the radioactive decay formula which is expressed as An = Aoe^-kt where An is the amount left after t time, Ao is the initial amount and k is a constant we can calculate from the half-life information. We do as follows:
at half-life,
ln 1/2 = -k(6)
k = 0.12/hr
An = 80e^-0.12(14)
An = 15.87 mg
Answer:
64 degree and 116 degree
Step-by-step explanation:
4y-44+3y+35=180(Linear pair)
7y=189
y=27
4(27)-44=64
3(27)+35=116
#Equation of m?
<h3>Equation</h3>
m = E/c²
<h3>Way to find it</h3>
E = mc²
E : c² = m
E/c² = m
So, the formula of m is E/c²
