A girl is snorkeling 1meter below sea level and then dives down another 0.5 meters. How far below sea level is the girl?

Answers

Answer:

She is 1.5 meters below the sea level


Explanation:

The sea level is indicated by the number 0

What's above the sea level is indicated by +ve numbers

What's below the sea level is indicated by -ve numbers


We know that:

originally, her depth was 1 meter below the sea level

This means that her original depth is -1


Now, she dives an extra 0.5 meters, to get her final depth, we would add -0.5 to the original -1 meters


This means that:

her depth = -1 + (-0.5) = -1.5 meters

where the negative sign indicates that she is below the sea level


Hope this helps :)
To calculate how far below sea level the girl is, you simply need to add 1 meter to 0.5 meters. This gives you the answer of 1.5 meters below sea level. (not sure what I can add to this answer)

Answers


A).  On a bar diagram where the bottom of the diagram is zero
       and the top of the diagram is 100%, a bar showing 21%
       must be 0.21 of the height from the base to the top.

B).  I don't know anything about the nitrogen in the Earth's

Is -0.3 a rational number? is 3.14144144414444... a rational number?

Answers

I will try to make this as simple as possible.

First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:

1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)

With that being said, let's begin.

First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing (-3)/(10) we have the equivalent of -0.3, so now we know it's a rational number.

As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:

-0.3 is a rational number, but 3.14144144414444 is not.
