Answer: 9 4/15
Step-by-step explanation:
Answer: 10 weeks
Step-by-step explanation: the first step is to subtract
400-250=150.
So he needs to save $150 to make $400.
Divide $150/$15 =10.
It means he has 10 weeks more to save for $150 to make $400.
Therefore the final answer is 10 weeks
Add up the numbers and divide by how many there are
(64 + 69 + 73) / 3 = 206/3 = 68.66
The amount of radioactive material remaining after 24 hours is 92.15 kg.
<h3>
Exponential function</h3>
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the amount of the substance after t hours.
From the equation, a = 100 mg
Also, after 6 hours:

After 24 hours:
y = 100(0.9966)²⁴ = 92.15 kg
The amount of radioactive material remaining after 24 hours is 92.15 kg.
