Which statement best describes Georgia’s Barrier Islands?
NemiM [27]

The statement that best describes Georgia’s Barrier Islands is; A: They protect the coastline during storms.

<h3>What is the correct statement about the place?</h3>

Barrier islands are called “barrier islands” due to the fact that they are good means of creating barrier between the mainland and the ocean.

Now, these barrier islands tend to shelter and protect the mainland from the powerful forces of wind, waves, and other natural disasters.  This they do by;

  • Sheltering the estuaries that form behind the barriers.
  • Allowing marshes to build up in the quiet waters of the sound.
  • Filtering of the pollutants that come in from mainland rivers by the marshes.
  • Providing valuable habitats for water animals and others in that ecosystem.
  • Serve aesthetic purposes

Barrier islands are a very much valuable resource. Despite the fact that they constantly change and may become badly eroded, they can still rebuild if left alone.

Thus, we can conclude that statement best describes Georgia’s Barrier Islands is that they protect the coastline during storms.

Directions: for questions 1 through 4, find the diagonal length of each solid figure.
Alex787 [66]
\text{The length of the diagonal is }11.2\text{ mm}

Here, we want to find the diagonal of the given solid

To do this, we need the appropriate triangle

Firstly, we need the diagonal of the base

To get this, we use Pythagoras' theorem for the base

The other measures are 6 mm and 8 mm

According ro Pythagoras' ; the square of the hypotenuse equals the sum of the squares of the two other sides

Let us have the diagonal as l

Mathematically;

\begin{gathered} l^2=6^2+8^2 \\ l^2\text{ = 36 + 64} \\ l^2\text{ =100} \\ l\text{ = }\sqrt[]{100} \\ l\text{ = 10 mm} \end{gathered}

Now, to get the diagonal, we use the triangle with height 5 mm and the base being the hypotenuse we calculated above

Thus, we calculate this using the Pytthagoras' theorem as follows;

\begin{gathered} d^2=5^2+10^2 \\ d^2\text{ = 25 + 100} \\ d^2\text{ = 125} \\ d\text{ = }\sqrt[]{125} \\ d\text{ = }11.2\text{ mm} \end{gathered}
