Which is larger: the number of meters across the Milky Way, or the number of cells in all humans? Explain or show your reasoning.

Some useful information: The Milky Way is about 100,000 light years across; There are about 37 trillion cells in a human body; One light year is about 10^16 meters; The world population is about 7 billion.

there are more cells in all humans than the number of meters across the Milky Way

Step-by-step explanation:

Here we are told that 1 light year is equivalent to:

We also know that the diameter of the Milky Way is

Therefore, the diameter of the Milky Way in meters is:

On the other hand, the world population is about 7 billion:

Every human body has about 37 trillion cells, which corresponds to

Therefore, the total number of cells in all humans is

The second number is larger: therefore, there are more cells in all humans than the number of meters across the Milky Way.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
