$102/8 hours= $12.75 per hr
Final answer: $12.75 per hr
Answer:
y - 4 = (2/3)(x - 7)
Step-by-step explanation:
(see attached for reference)
we are given slope, m = 2/3 and point (x₁, y₁) is (7,4)
y - y₁ = m(x - x₁)
substituting the given values into the general equation
y - y₁ = m(x - x₁)
y - 4 = (2/3)(x - 7)

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 = <em>20 units</em>
