This problem can be solved using the <u>Radioactive Half Life Formula:
</u>
<u />
(1)
Where:
is the final amount of the material
is the initial amount of the material
is the time elapsed (the quantity we are asked to find)
is the half life of americium-241
Knowing this, let's find from (1):
Applying natural logarithm in both sides:
<u></u>
<u>Finally:</u>
She saved 64 cents each week since you would simply divide the money by 5 weeks to get the amount of money she gets per week
1. Vertical
2. Adjacent
3. Complementary
4. 72
5. X= 33
the volume of a cone with a height of 27cm and a radius of 13cm is 4748.36242611007.Then you round it to the nearest tenth which would be 4,778.4 which would be the answer
you work out that by v=PI radius squared height divided by 3
Answer:
x = 3
Step-by-step explanation:
Given
4 : 8 = x : 6, expressing in ratio form, that is
= 
( cross- multiply )
8x = 24 ( divide both sides by 8 )
x = 3
Thus 4 : 8 = 3 : 6
