Answer:
The very first one is 22
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
6 1/2 = 6 + 1/2 *3/3 = 6 + 3/6
4 5/6
6 3/6
-4 5/6
-----------------
We need to borrow from the 6
6 3/6 = 5 + 6/6 + 3/6 = 5 9/6
5 9/6
-4 5/6
--------------------
1 4/6
We can simplify 4/6 to 2/3
Solution: 1 2/3
I don't really understand this question do u have a pic
We rewrite the equation:
y = y0 * e ^ (- 0.0002 * t)
In this equation:
I = represents the initial amount of the isotope
We have then:
89% of the isotope left:
0.89 * y0 = y0 * e ^ (- 0.0002 * t)
We clear the time:
e ^ (- 0.0002 * t) = 0.89
Ln (e ^ (- 0.0002 * t)) = Ln (0.89)
-0.0002 * t = Ln (0.89)
t = Ln (0.89) / (- 0.0002)
t = 582.6690813
round to the nearest year:
t = 583 years
Answer:
There will be 89% of the isotope left in about:
t = 583 years
Answer:
44⁰.
Step-by-step explanation:
Its supplement = 180 - 136
= 44 degrees.
