Answer: 50 mg

Step-by-step explanation:

Substituting into the half-life formula, we get that

$N(t)=800\left(\frac{1}{2} \right)^{t/25}$

So, after 100 years,

$N(100)=800\left(\frac{1}{2} \right)^{100/25}=\boxed{50 \text{ mg}}$

Two classes have a total of 50 students. One of the classes has 6 more students than the other. How many students are in the lar

Talja [164]

To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.

1st class - X = no of students
2nd class - X + 6 no of students

Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.

1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.

There are 28 students in the larger class.
