The surface area of the solid pyramids are as follows;

First figure; 436 square units

Second figure; 319 square units

Third figure; 673 square units

A pyramid is a shape that consists of a polygon base and side faces that are triangular.

First figure

The figure is a pentagonal pyramid of height 8 units and side length of 10 units

The apothem, a, can be obtained from the formula;

[tex]a = \dfrac{s}{2\cdot tan \left(\dfrac{180}{n} \right)}[/tex]

s = 10

n = 5

[tex]a = \dfrac{10}{2\cdot tan \left(\dfrac{180}{5} \right)} \approx 6.88[/tex]

Slant height ≈ √(8² + 6.88²) ≈ 10.55

Area of the 5 triangles = 5 × (1/2) × 10 × 10.55 ≈ 263.75

Area of pentagonal base ≈ (1/2) × 6.88 × 5 × 10 = 172
Area of the figure ≈ 263.75 + 172 ≈ 436

Second figure;

Square pyramid

n = 4

When s = 8, we get;

[tex]a = \dfrac{12}{2\cdot tan \left(\dfrac{180}{4} \right)} =6[/tex]

Slant height of the 8 units long side = √(6² + 10²) ≈ 11.66

Area of two of the four triangle surfaces = 2×(1/2)×8 ×11.66≈ 93.28

When s = 12 we get;

[tex]a = \dfrac{8}{2\cdot tan \left(\dfrac{180}{4} \right)} =4[/tex]

Slant height of the 12 units long side = √(4² + 10²) ≈ 10.77

Area of two of the four triangle surfaces = 2×(1/2)×12 × 10.77 ≈ 129.24

Area of the rectangular base = 12 × 8 = 96

Area of the figure = 93.28 + 129.24 + 96 ≈ 319

Third figure

Octagonal pyramid

n = 8

s = 8

[tex]a = \dfrac{8}{2\cdot tan \left(\dfrac{180}{8} \right)}\approx 9.66[/tex]

Slant height = √(9.66² + 6²) ≈ 11.37

Area of the 8 triangles = 8 × (1/2) × 8 × 11.37 ≈ 363.84

Area of the octagonal base = 2×(1 + √2)×s²

Therefore;

2×(1 + √2)×8² ≈ 309.02

Area of the figure ≈ 363.84 + 309.02 ≈ 673

Answer:

Explanation:

First step is to multiply the expression in brackets on the left side by 0.5

0.5(x+8)=x−4

Now we can move the unknown x to left side and the numbers to right side

x+4=x−4

The last equality is false, so the original equation has no solutions.

x−x=−4−40=−8

The value of x is 10.

Parallel lines are those straight lines that are always the same distance apart from each other. Parallel lines never meet, no matter how much they are extended.

Given that, three lines parallel to each other,

We know, segments in parallel lines are in equal proportion,

5/4 = (2x-10)8

10 = 2x-10

2x = 20

x = 10

Hence, the value of x is 10.

Earth's radius is 6.38 x 106 meters, its mass is 5.97 x 1024 kg, and its orbital radius is 1.5 x 1011 meters. The period of the earth's rotation is 24 hours, or 86400 seconds. The period of its revolution is one year, or 3.156 x 107.

Finding the angular momentum entails

L = mE x r2 x w L = 2.6742 x 1040kg.m2.s-1

I= 2/5M.R2 L8= 7.07 x 1023kg.m2.s-1 for a homogeneous sphere with mass M, radius R, and an axis through its center.

Earth's angular momentum in a circular orbit around the sun is measured at Li=2.6742 x 1040 kg.m2.s-1.

Given that the radius of the planet is so small in comparison to the distance from the sun, it makes sense to model the earth as a particle.

L8= 7.07 x 1023 kg.m2.s-1 is the size of the earth's angular momentum as a result of its revolution around an axis passing through the north and south poles.

Parameters and Calculations:

Earth's mass, mE, is 5.97 x 1024 kg, and its radius, R,

the earth's orbital parameters are as follows: RE= 6.38 x 106 m, r= 1.5 x 1011 m, t=24h = 86400 s, and t=1 year = 3.156 x 107

If the length of the room in drawing is 3 inches, then the actual length of the room is 24 feet

The scale of the drawing of a hotel = 1 inch : 8 feet

The length of the room in the hotel in the drawing = 3 inches

Consider the actual length of the room as x

Then the proportion will be

1 inch / 8 feet = 3 inches / x feet

Cross multiply the terms and find the value of x

1 × x = 3 × 8

Multiply the numbers

x = 24 feet

A plaintiff who sues on the basis of disparate-treatment discrimination in hiring must make out a prima facie case of illegal discrimination and will win in the absence of a legally acceptable employer defense. True

Disparate treatment discrimination refers to the form of discrimination from an employer who blatantly treats an employee, or a potential employee differently based on the individual’s race, religion, color, sex, national origin, etc. It is intentional employment discrimination. A plaintiff who sues on the basis of disparate-treatment discrimination in hiring must make out a prima facie case. Prima facie case refers to a cause of action or defense that is sufficiently established by a party's evidence to justify a verdict in their favor, provided such evidence is not rebutted by the other party. The facts of the case are assumed to be true unless contradicted by evidence, hence if the plaintiff has produced sufficient evidence of their claim that the case will be decided for the plaintiff unless the defendant produces evidence to rebut it. To establish prima facie case, the plaintiff must be a member of the a protected class, must have applied and was qualified for the job in question, was rejected by the employer, and employer continued to seek applicants for the position or filled the position with a person not in a protected class. If plaintiff establishes all of this, burden now falls on employer as they must then prove their reasoning.

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.

Given: Dean Halverson recently read that full-time college students study 20 hours each week.

She decides to do a study at her university to see if there is evidence that students study an average of more than 20 hours each week.

A random sample of 35 students were asked to keep a diary of their activities over a period of several weeks.

It was found that the average number of hours that the 35 students studied each week was 21.1 hours.

The sample standard deviation of 4.3 hours.

H0: μ = 20

H0: μ > 20

n = 35

X bar = 21.1

s = 4.3

Test statistics = t = (X bar - μ) / (s / √n)

The value of cost of all the product is 32.50

The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of competing companies in the market.

Formulas and Calculations for Sale Prices Percent Off Price Formula

List price - (List price x (percentage / 100)) = Discounted price

For instance, the sale price is 25% off the list price of $130.

Divide 25% by 100 to get the decimal equivalent: 25/100 = 0.25

Divide the list price by the decimal percent: 130*0.25 = 32.50

Subtract the amount of the discount from the list price: 130 - 32.50 = 97.50

Using the formula:

130 - (130*(25/100)) =

\s130 - (130*0.25) =

       \s130 - 32.50 = 97.50

25% off $130 is $97.50

Formula for Fractional Off Price

List price - Discounted price (List price x fraction)

Example: The sale price is one-third of the list price of $120.

Divide the list price by the fractional discount: 120*1/3 = 40

Subtract the amount of the discount from the list price: 120 - 40 = 80
