Volume is a measurement that quantifies the amount of three-dimensional space occupied by an object, substance, or region.

Volume is a fundamental physical quantity that describes the extent or size of an object in the context of its three dimensions: length, width, and height.

Volume is commonly expressed in cubic units, such as cubic meters (m³), cubic centimeters (cm³), cubic inches (in³), or cubic feet (ft³), depending on the system of measurement used. It can apply to various entities, including solid objects, liquids, gases, or even abstract concepts like the volume of data.

For solid objects, the volume represents the total amount of space enclosed within its boundaries. It is typically determined by measuring or calculating the product of the object's length, width, and height or through more complex mathematical formulas for irregular shapes.

In the case of liquids or gases, the volume refers to the amount of space occupied by the substance within a container. It can be measured directly using tools such as graduated cylinders or indirectly through displacement methods.

Understanding volume is essential in fields like physics, engineering, architecture, chemistry, and many others where knowledge of spatial quantities is required for designing, analyzing, or describing various objects or systems.

Answer:

0.1111.... = [tex]\frac{1}{9}[/tex].

Step-by-step explanation:

Given  : 0.1 repeating

To find : Which rational number equals 0.1111......

Solution : We have given 0. 11111.........

We can see there is only one number is repeating , we will multiply it by 10

Let  x = 0.1111.......

Multiply both sides by 10

10x = 10 * 0.1111.......

10x = 1.1111.......

We can write it in terms of x

10x = 1. 000 + 0.11111....

10 x = 1 + x

On subtracting both sides by x

10 x -x = 1

9 x = 1

On dividing both sides by 9

x = [tex]\frac{1}{9}[/tex].

0.1111.... = [tex]\frac{1}{9}[/tex].

Therefore, 0.1111.... = [tex]\frac{1}{9}[/tex].

The rational number that equals 0.1 repeating is 1/9.

The rational number that equals 0.1 repeating can be represented as follows:

Let x = 0.1 repeating

To convert the repeating decimal to a fraction, we can use the following method:

Let's multiply both sides of the equation by 10 to shift the decimal point one place to the right:

10x = 1.1 repeating

Now, subtract the original equation from this new equation to eliminate the repeating part:

10x - x = 1.1 repeating - 0.1 repeating

9x = 1

Divide both sides of the equation by 9 to solve for x:

x = 1/9

Therefore, the rational number that equals 0.1 repeating is 1/9.

Final answer:

To calculate the total distance Gabriella flew in four shows at the circus, add up the distances she covered in each performance.

Explanation:

The total distance Gabriella flew on Saturday can be calculated by adding up the distances she covered in each show:

Distance 1: 8.05 meters

Distance 2: 17.71 meters

Distance 3: 14.38 meters

Distance 4: 19.35 meters

By adding these distances together, you can find the total distance Gabriella flew that day i.e. 8.05+17.71+14.38+19.35 =  59.49 m

Using Pythagoras theorem,  the ladder must be 19.7ft long.

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

Perpendicular = height of the window from the ground = 17ft

Base = distance of the foot of the ladder from the base of the building = 10ft

Hypotenuse = [tex]\sqrt{perpendicular^{2} +base^{2} }[/tex]

H = [tex]\sqrt{17^{2}+10^{2} }[/tex] = 19.4ft

An equation in slope-intercept form models given situation is y=0.6x+20 and the length of the sunflower after two weeks is 21.2 meters.

Given that, a sunflower in Julia Rosario's garden was 12 centimetres tall when it was first planted. Since then, it has grown approximately 0.6 meters per day.

We need to write an equation in slope-intercept form that models this situation.

The slope-intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis). The equation of the line is the equation that is satisfied by each point that lies on that line.

The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y = mx + b.

Let y be the length of a sunflower plant and the number of days be x.

Now, y=0.6x+20

The length of the sunflower after two weeks is y=0.6×2+20

⇒y=1.2+20=21.2 meters

Therefore, an equation in slope-intercept form models given situation is y=0.6x+20 and the length of the sunflower after two weeks is 21.2 meters.
