Answer:
$10.94
Step-by-step explanation:
In the given formula, T is in years. 3 months is 3/12 years, so your interest is ...
I = PRT
I = $500×0.0875×1/4 = $10.9375 ≈ $10.94
$10.94 is the interest paid on the loan.
Answer: In 10 hours, 4000 bacteria will be present.
Step-by-step explanation:
Given that 2000 bacteria grew to 2400 in 2 hours,
growth/ increase rate = 2400 - 2000
= 400 bacteria increase in 2 hours
Per hour is therefore 400/2 = 200 bacteria increase per hour
If the bacteria increases by 200 per hour
If 200 = 1 hour
X = 10 hours
We cross multiply:
X = 200 x 10
X = 2000
Therefore, a culture with 2000 bacteria at the same growth rate will have increased by additional 2000 in 10 hours
So, after 10 hours, number of bacteria will be 2000 + 2000 = 4000 bacteria
The answer is An hour and a half
