Question

The theory of continental drift describes the movement of landmasses on Earth's surface Which of the following shows evidence of continental drift? (1 point) fossil evidence glacial deposits ☐ match up of landforms, rocks, and other resources all of the above none of the above

Answer 1

5 - (-4)

Answer 2

(15, -2) / (-5, 2)

Answer 3

Fraction?

Answer 4

2 - (2)
-5 - 15

Answer 5

-5 - 15

Answer 6

The correct answer is "all of the above." Each of the listed options provides evidence for the theory of continental drift:

1. **Fossil evidence** - Similar fossils found on different continents suggest that these landmasses were once joined.
2. **Glacial deposits** - Glacial marks and deposits found in currently warm regions indicate that those continents were once located closer to the poles and connected.
3. **Match up of landforms, rocks, and other resources** - Similar geological features and rock formations on different continents support the idea that they were once part of a single massive landmass.

Thus, "all of the above" is the best choice.

Answer 7

To solve the expression \(5 - (-4)\), you can simplify it as follows:

Subtracting a negative number is the same as adding its positive counterpart, so:

\[
5 - (-4) = 5 + 4
\]

Now, perform the addition:

\[
5 + 4 = 9
\]

Therefore, \(5 - (-4) = 9\).

Answer 8

To perform the division of the two coordinate pairs \((15, -2)\) and \((-5, 2)\), we divide the corresponding components of the tuples.

The division is done component-wise:

\[
\left(\frac{15}{-5}, \frac{-2}{2}\right)
\]

Now, we compute each component:

1. For the first component:
\[
\frac{15}{-5} = -3
\]

2. For the second component:
\[
\frac{-2}{2} = -1
\]

Thus, the result of \((15, -2) / (-5, 2)\) is:

\[
(-3, -1)
\]

Answer 9

I apologize for the misunderstanding! If you want the division of the two coordinate pairs \((15, -2)\) and \((-5, 2)\) expressed as a fraction, we can interpret this as dividing each component as a fraction rather than producing a coordinate result.

So we would set it up as:

\[
\frac{(15, -2)}{(-5, 2)} = \left( \frac{15}{-5}, \frac{-2}{2} \right)
\]

Calculating each fraction:

1. For the first fraction:
\[
\frac{15}{-5} = -3
\]

2. For the second fraction:
\[
\frac{-2}{2} = -1
\]

Therefore, we have two components, but they can also be expressed as the fractions:

- The first component is \(-3\) (which can be written as \(\frac{-3}{1}\) if necessary).
- The second component is \(-1\) (which can be written as \(\frac{-1}{1}\) if necessary).

So if you are looking for the fractional representation of the results, it remains \((-3, -1)\) or can be represented as:

\[
\left(\frac{-3}{1}, \frac{-1}{1}\right)
\]

If you meant something else by "fraction," please clarify!

Answer 10

To simplify the expressions you've provided, we can solve them individually.

1. **For the first expression:**
\(2 - (2)\)
This simplifies to:
\(2 - 2 = 0\)

2. **For the second expression:**
\(-5 - 15\)
This simplifies to:
\(-5 - 15 = -20\)

So the results are:
- \(2 - (2) = 0\)
- \(-5 - 15 = -20\)

Answer 11

To evaluate the expression \(-5 - 15\), you simply subtract \(15\) from \(-5\):

\[-5 - 15 = -20\]

Therefore, the result is \(-20\).
