Answer:

To find out how much money is allotted for each of these items, we can multiply the percentage of the income allocated to each item by the total income.

Food: 20% of $25,000 = $25,000 x 0.20 = $5000

Shelter: 25% of $25,000 = $25,000 x 0.25 = $6250

Clothing: 15% of $25,000 = $25,000 x 0.15 = $3750

So the family has $5000 for food, $6250 for shelter and $3750 for clothing.

The first piece is 7.2 feet long, and the second piece is 12- 7.2 = 4.8 feet long.

The ratio of the two pieces is 3 to 2. This means that the length of the first piece is 3/5 of the total length, and the length of the second piece is 2/5 of the total length.

If we let x be the length of the first piece, the length of the second piece is:

12 - x

Since the ratio of the two pieces is 3 to 2, we can set up the equation:

(3/5) * 12 = x

Solving for x:

x = 7.2

So, the first piece is 7.2 feet long, and the second piece is 12- 7.2 = 4.8 feet long

Step-by-step explanation:

Answer: 77m

Step-by-step explanation:

The equation for the perimeter of a rectangle is: p = 2(length) + 2(width). We are given both perimeter and the length, so we can plug in these values to solve for what is missing.

332m = 2(89) + 2(width)

332m = 178 + 2(width)

154 = 2(width)

width = 77

Just combine like terms and get the variable (width) by itself on one side of the equation to solve. Hope this helps!

Answer:

width = 77 m

Step-by-step explanation:

Perimeter = sum of all sides

As a rectangle has 2 lengths and 2 widths making a total of four sides;

P = 2 ( l + w)

332 = 2 ( 89 + w)

332/2 = 89 + w

166 = 89 + w

166 - 89 = w

77 = w

Therefore, the width of the pool is 77 m

The value of x, considering the area of the rectangular regions, is given as follows:

x = 12.

The area of a rectangle is given by the multiplication of the two dimensions of the rectangle.

The area of the shaded region is obtained subtracting the area of the entire rectangle by the area of the inner white rectangle.

The area of the entire rectangle is given as follows:

(x + 8)(x + 5) = x² + 13x + 40.

The area of the white region is given as follows:

(x + 2)(x - 3) = x² - x - 6.

Hence the area of the shaded region is given as follows:

x² + 13x + 40 - (x² - x - 6)

x² + 13x + 40 - x² + x + 6

14x + 46.

As the area of the shaded region is of 214 units squared, the value of x is obtained as follows:

14x + 46 = 214

14x = 168

x = 168/14

x = 12.

The area of the shaded region is 36.53 cm^2 and the perimeter of the shaded region is 8π cm.

What is area and perimeter?

The area of a shape or figure is its area, whereas the perimeter of a shape is its outer boundary over a given distance. Area is measured in square units or unit2 while perimeter is measured in the same unit.

The circumference of a shape is known as its perimeter. The lengths of all four sides must be added in order to determine a rectangle's or square's perimeter.

Radius, r = 8 cm

Perimeter of a circle = 2πr

Perimeter of s quarter circle = 2πr/4 = 1/2πr

Perimeter of Shaded part = 1/2 * 2πr

                                          = 1/2 × 2 × π × 8

                                          = 8πcm.

Area of a circle = 2πr²

Area of quarter circle = 2πr²/4 = 1/2πr²

Area of a square = length ²

Area of Shaded part = Area of Quarter-circle - Area of Square

                                  = 0.5π(8)² - 8²

                                   = 0.5π(64) - 64

Area of Shaded part  = 36.53 cm^2

The data shows mean concentrations (mg/l) of pollutants in rainwater leaving either green or conventional roofs. Correct Option is: (D)The Total Volume of Rainfall is needed to calculate the total amount of a pollutant leaving the roof during and following a rainstorm.

Volume:

Precipitation intensity is the water depth (mm) recorded during a shower divided by the duration of the shower (hours).

Expresses water depth per hour in millimeters (mm/hour).

[tex]rainfall intensity = total amount of rainwater(mm)/ duration of the rainfall (hours)[/tex]

A volume is a measure of three-dimensional space. Often quantified numerically using SI units (such as cubic meters and liters) or using various imperial or US customary units (such as gallons, quarts, and cubic inches). The definition of length (cube) relates to volume. Container volume is generally understood to mean the capacity of the container. That is, the amount of liquid (gas or liquid) that the container can hold, not the amount of space that the container itself moves.

In ancient times, volume was measured using similarly shaped natural vessels and later standardized vessels. The volume of some simple 3D shapes can be easily calculated using arithmetic formulas. The volume of more complex shapes can be calculated using integral calculations if there is an equation that constrains the shape. Zero, one, and two dimensional objects have no volume. In four dimensions and above, a concept analogous to ordinary volumes is a hypervolume.

Volume of Rainfall:

The Average Rainfall = Depth x Radius x Radius x 3.14. The area at the top of the bucket (this is the area where rain is collected). Dividing the precipitation by this area will give you the precipitation.

The maximum is N*(N-1)/2 and the minimum is N-1 if there are N vertices.

Proof:

Consider an adjacency matrix where each entry is either 1 (to denote the presence of an edge) or 0 (to indicate the absence of an edge) (to indicate the absence of an edge). Each row of the upper triangle must have at least one "1" in order for a graph to be connected.

By merely placing one 1 in each row of the upper triangle, the minimum is reached. Now, if the adjacency matrix is N by N, the first row will have N-1 elements in the upper triangle, the second row will have N-2 elements, the third row will have N, the fourth row will have N, and so on until the last row will have 0 items. Consequently, there are N total rows  "with an upper triangle", each with only one 1. Hence, the number of edges in N-1.

The maximum occurs if every element of the upper triangle has one. Now, the number of elements in the upper triangle of the whole matrix is

What is the function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

The x value of a point where a vertical line intersects a function represents the input for that output y value.

If we can draw any horizontal line that intersects a graph more than once, then the graph does not represent a function because that y value has more than one input.

If we draw a line parallel to the y-axis it cuts the graph in more than one point.

starting location the ball = (-40. -50)

In order to find the possible x-coordinates of Q,

The coordinates of the rightmost edge of the golf course = (35, 0)

slope = m = ( y2 - y1)/ ( x2 - x1)

now , the equation for a circle is known as , (x - h)² + (y - k)² = r²
