Step-by-step explanation:
Answer:
5/12x
Step-by-step explanation:
x+2/4x^2+5x+1 *4x+1/4x^2-4
x+2/16x+5x+1*4x+1/16x-4
x+2/21x+1 (4x+1/16x-4)
-x . -x .
2/20x+1 (4x+1/16x-4)
-1 . -1 .
20x(4x+1/16x-4)
(80x+20x/320x-80x)
100x/240x
5/12x
To solve this we are going to use the half life equation
Where:
is the initial sample
is the time in years
is the half life of the substance
is the remainder quantity after
years
From the problem we know that:
Lets replace those values in our equation to find
:
We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Answer: 75ft
Step-by-step explanation: if you take 3 yards and multiply it by 25 you get 75, or you can do It the long way and add 3, 25 times.
