Answer:
600 ft cubed
Step-by-step explanation:
Triangle volume formula V = 1/2(l*w*h)
1/2(4*12*9) = 216 ft cubed
Formula for rectangular prism V = (l*w*h)
(4*16*6) = 384 ft cubed
Adding the values: 600 ft
Answer: The age of the fossilized leaf is 13829 years.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process =
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for finding the age
The age of the fossilized leaf is 13829 years.
Perctange is based on the total number. in this case you don't know it so you cant make such a guess.
