The correct answer is C. Radioactive dating

Explanation

Radiometric dating also called radioactive dating is a scientific method to know the age of rocks and old data objects. This method is based on the number of radioactive atoms (unstable by nature) that, over time, disintegrate into stable atoms. Therefore, to know the age of a rock, scientists compare the amount of unstable radioactive atoms with the number of stable atoms to know their age. This method has been one of the most effective ones to know the age of Earth as though this scientist can determine the age of the oldest fossils or rocks and based on this they can know how long has Earth existed. So, the correct answer is C. Radioactive dating

How does information communicates economic, social, and environmental information in new Orleans following hurricane Katrina
Vikki [24]
Because it shows the ages of the population, so we can see the parts of the place with the population that can and can't work.
Now, the way these maps show social information is: because they point out the demographical distribution about a specific sub-group in the population, its age, and its growth.
And finally, the way these maps provide environmental information is: because they allow us to see the environment of certain zones inside the map territory.

Given: The length of side x is 89.75 cm.
babymother [125]

Answer:

y= 155.45 cm

Explanation:

To solve this, we will need to use the Law of Sines

This states that:

\frac{a}{sinA} =\frac{b}{sinB}

Firstly, we need to find the sin of angle y. As this is a 30-60-90 right triangle, we know that the angle must be 60 degrees

Now that we have side x, the angle X, and the angle Y, we can solve for the side y using the Law of Sines

Lets plug in our known values into the equation

\frac{89.75}{sin(30)} =\frac{y}{sin(60)}

Next we can solve for y

\frac{89.75sin(60)}{sin(30)} =y

When plugged into a calculator, you get the value of 155.45 cm for side y
