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.
Answer:
Increase by $145
Step-by-step explanation:
= $ (x + 145 + 145)
= $ (x + 290)
Answer:
AC ≅ AE
Step-by-step explanation:
According to the SAS congruence theorem, if two triangles have 2 corresponding sides that are equal, and also have one included corresponding angle that are equal to each other in both triangles, both triangles are regarded as congruent.
Given ∆ABC and ∆ADC in the question above, we are told that segment AB ≅ AD, and also <BAC ≅ <DAC, the additional information that is necessary to prove that ∆ABC and ∆ADC are congruent, according to the SAS theorem, is segment AC ≅ segment AE.
This will satisfy the requirements of the SAS theorem for considering 2 triangles to be equal or congruent.
Answer:
divided by -5
Step-by-step explanation:
Since there are 100 cents in a dollar, routing to the nearest cent would be rounding to the nearest hundredth. In order to do that you would solve to the thousandths place the use that number to round up or down to the nearest hundredth.
For example:
If a dozen roses cost $12.35, how much does each rose cost?
12.35 ÷ 12 = 1.029
The 9 is in the thousandths place. If it is 5 or higher we round the hundredths place up, so our answer is each rose costs 1 dollar and 3 cents ($1.03)
