Step-by-step explanation:
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.

Perimeter = 2(length) + 2(width)
= 2(35) + 2(25)
= 70 + 50
= 120
Answer: 120 meters
Answer: 125 pounds
Step-by-step explanation:
Let's first represent the weight of the black rhinoceros and chimpanzee with variables. We will assign <em>r</em> for the rhinoceros and <em>c</em> for the chimpanzee.
In the question, we were given that the weight for a black rhinoceros is 18 times as much as an average-size chimpanzee. This makes 18 times the chimpanzee's weight equal to the rhinoceros' weight.
Let's put this into an equation.

Now, let's put in the values we know to find the weight of the chimpanzee (i.e., <em>c</em>). We know the weight of a rhinoceros (represented by <em>r</em>) is 2250 pounds, so we can replace it for <em>r</em> in the equation.

To solve this equation, we can divide both sides by 18 to get c by itself and know what it's value is.

We can remove the
from the right side to be left with c. We can also divide 2250 by 8 to get the weight of an average-size chimpanzee.

Hence, an average-size chimpanzee weighs 125 pounds.
