Answer:
20 units
Step-by-step explanation:
Initial particle concentration = 80 units
Particles removed each hour = 50% of the remaining particles
To find:
Particle concentration after 2 hours = ?
Solution:
Particles removed in 1 hour = 50% of remaining particles
i.e. Particles removed in 1 hour = 50% of initial concentration
Particles removed in 1 hour = 50% of 80 = 40
Particles removed in next 1 hour = 50% of remaining particles
i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour
Particles removed in next 1 hour = 50% of 40 = 20
Total particles concentration removed in 2 hours = 40 + 20 = 60 units
Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours
= 80 - 60 = 20 units

Answer:
The answer is
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,4) and (4,-6)
The distance between them is
We have the final answer as
Hope this helps you
Hello There!
Median: The middle number when all the numbers are listed in oder from least to greatest.
To find the median, place the numbers in order from least to greatest.
In this case, the numbers would be 4, 5, 8, 9, 10
The middle number would be 8 so the median for this set of numbers is 8.
The fourth term of the sequence will be 110
The given expression forms a sequence 5, 10, 30 ...
First term = 5
Second term = 10
Third term = 30
Let the fourth term be x
Taking their common difference
10 - 5 = 5
30 - 10 = 20
Since the multiplicity of the common difference is 4
Then T4 = 20(4) + 330
T4 = 80 + 30
T4 = 110
Hence the fourth term of the sequence will be 110
