The total fencing material needed for the triangular plot is 537.03 feet.

A trigonometric law: the square of a plane triangle's side equals the sum of the squares of a remaining sides minus double the the product of such sides as well as the cosine of a angle between them.

If the triangle ABC is having the sides a, b and c.

Then, the formula for law of cosine is;

c² = a² + b² - 2abcosC

Now, as per the given question;

The first step is to compute the length of the fence's third side. The following formula can be used to calculate the length of a third side:

c² = a² + b² - 2abcosC

Where a,b and c are the three sides and C is the angle forming between sides a and b.

The sides are a = 160 feet, b = 160 feet.

The angle between the sides a and b is 85 degrees.

Now, estimate for c by substituting all the value in the formula.

c² = 160² + 160² - (2 x 160 x 160)cos85

c² = 51,200 - 51200 x0.087

c = √47104

c = 217.03 feet

Now, the total length of the perimeter = 160 + 160 + 217.03

                                                               = 537.03 feet                

Therefore, the total length of the perimeter of the fencing material is found to be 537.03 feet.

Qualitative data depicts qualities or characteristics. This type of data is qualitative and nominal.

Qualitative data are the conceptual and descriptive findings gathered by surveys, interviews, or observation. We can explore concepts and provide more context for quantitative findings by analyzing qualitative data.

Qualitative data exist as measures of "types" and can be represented by a name, symbol, or number code, whereas quantitative data exist as information on numerical variables (such as how many, how much, or how frequently).

Numbers are used to expressing measures of values or counts in quantitative data. Binary, nominal, and ordinal are the three primary forms of qualitative data.

Qualitative data comes in a wide variety of forms, including those used in statistics, work, and research. This type of data is qualitative and nominal.

Answer:

let's say (5x + 2) = y

then that means 118° + y = 180°(angle in a straight line)

therefore y =180 - 118= 62°

since y = 5x + 2

and y= 62°

therefore 5x + 2 = 62°

5x = 62- 2= 60°

therefore 5x = 60°

this means that x = 60 ÷5 = 12°

Measure of angle 4 i.e. m∠4 = 50°

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Also, ∠5 = ∠4 (alternate interior angles)

Thus, m∠4 = 50°

Based on the total budget of Mr. Bell for the incentive and the cost of a pizza box, the equation that matches the word problem is 60 ≥ 9.25x

The amount that Mr. Bell will spend at the most is the budget for the incentive of $60.

He will not spend more than this amount but will spend a maximum of it. This amount of $60 is therefore equal to or greater than the cost of the pizzas:

60 ≥ cost of the pizza

The cost of the pizza is:

= Cost per pizza box x number of boxes

= 9 × x

If the total charge on 8 particles is -56 units and all the particles have the same charge, then the charge on each particle is equal to -7 units.

The charge on each particle can be determined by division.

Division is a part of the basic operations of arithmetic which are four in number, the rest being addition, subtraction, and multiplication. It can be considered the opposite of multiplication and involves separating into equal parts or groups.

The change on each particle can be calculated by dividing the total charge units by the total number of particles. Hence,

charge on each particle = total charge units ÷ total number of particles

charge on each particle = -56 / 8

charge on each particle = -7

Therefore, the charge on each particle is equal to -7 units if all the particles have the same charge.

Thus the tax rate is 1.5% and the 1.5% tax value of $135,000 is $2025.

We are given that;

A homeowner whose house was assessed at $120,000 pays $1,800 in taxes.

At the same rate, we need to find out what the tax value on a house assessed at $135,000.

The rate is always in percentage. Thus;

Tax value = 5% of 100

= 5/100 x 100

= $5

We have,

House cost = $120,000

Tax amount = $1800.

Let the rate be R%

Now;

R/100 * 120,000 = 1800

R * 1200 = 1800

R = 1800/1200

R = 18/12 = 1.5

R = 1.5%

The tax rate is 1.5%

The 1.5% tax value of $135,000 = 1.5 / 100 * 135,000

= 15/1000 x 135,000

= 15 x 135

= $2025

The tax value is $2025.

Thus the tax rate is 1.5% and the 1.5% tax value of $135,000 is $2025.

Step-by-step explanation:

The lower line has slope 2 and passes through (0, 0). The clear circle indicates that the point where x = 1 is not included.

If an artist uses gold leaf foil in his work and he wants to cover a piece of canvas that is 22.5 by 34 inches with this foil and the foil costs $4.15 per square inch, then the money the artist spent on gold leaf foil for this project is equal to $3174.75

The money spent on gold leaf foil for the project can be calculated by the multiplication of the area or square inch of the foil needed to cover the piece of canvas with the price per square inch.

The area or square inches can be calculated by multiplying the length in inches by the width in inches.

Area = 22.5 × 34

Area = 765 square inches

Now, money spent on gold leaf foil can be calculated by multiplication of the area of the need with the price per square inch.

Area × price per square inch

765 ×  4.15 = $3174.75

Hence the money the artist spent on gold leaf foil is calculated to be $3174.75
