alexira [117]

Answer:

311%

Step-by-step explanation:

The percentage change is calculated as ...

percent change = ((new value) -(old value))/(old value) × 100%

Filling in the numbers, we have ...

percent change = (181.5 -44.2)/44.2 × 100% ≈ 311%

The global area increased by 311% over the interval.

On a hot summer day, Jen is in a foreign country. She wonders which

tino4ka555 [31]

Answer: Celsius scale

Step-by-step explanation:

Fahrenheit scale is established from the freezing and boiling temperatures of water, which are:

Freezing temperature of water: $32\°F$

Boiling temperature of water: $212\°F$

Which means that all temperatures below $32\°F$ are below the freezing temperature of water. Therefore, if Jen is in the Summer season, which is characterized by high temperatures, it is incoherent to think that the thermometer is using the Farenheit scale.

Now, $30\°C$ is in accordance with the high temperatures recorded in the summer season.

If we want to know how much $30\°C$ is in Farenheits, we must use the following conversion formula:

$(30\°C)(\frac{9}{5})+32=86\°F$

<h3>Inequality</h3>

An inequality is a relation between two numbers and/or expressions that are related via <, >, ≥ or ≤ sign.

A strict inequality is an expression that uses < and >. It tells us that one side is only more or less than the other side.

When 2 simple inequalities are joined by or and, we get a compound inequality.

When solving an inequality, the solution will be a range of values called its solution sets. The inequality will remain true for every single value in this range.

The inequality signs are;
