What is the area of a regular polygon with 100 sides and a perimeter of 100 units?

Answers

Answer 1
now, if the regular polygon has 100 sides, and the perimeter is 100 units, that simply means that each side is 1 unit, foot, meter, else.

so, we know each side is 1 unit long, and we know there are 100 sides,

[tex]\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{4}ns^2cot\left( \frac{180}{n} \right)\quad \begin{cases} n=\textit{number of sides}\\ s=\textit{length of a side}\\ \frac{180}{n}=central~angle\\ \qquad~~ in~degrees\\ ----------\\ n=100\\ s=1 \end{cases} \\\\\\ A=\cfrac{1}{4}\cdot 100\cdot 1^2\cdot cot\left( \frac{180}{100} \right)\implies A=25cot\left(\frac{9}{5}^o \right) \\\\\\ A\approx 795.51289884[/tex]

Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?

Answers

Two parallel lines have the same slope.  If line w is perp. to y = 34x - 11, we must find the slope of  y = 34x - 11  and then find the negative reciprocal of that slope.  That (neg. recip.) slope will be the slope of line w.

The slope of y = 34x - 11 is 34, and the neg recip. of that is -1/34:  slope of w.

Use the point-slope form of the equation of a str. line to find the eqn. of line w:

y - 10 = (-1/34)*(x - (-6) )   =>  y - 10 = (-1/34)(x+6).  This could be rewritten in other forms if desired.

Answer:

y = -1/34 . x + 167/17

Step-by-step explanation:

The slope-intercept form of a linear equation is:

y = m.x + b

where,

m is the slope

b is the y-intercept

Line v is perpendicular to the graph of y = 34 x - 11. If 2 lines are perpendicular, the slope of one is the inverse and opposite of the other. Then, the slope of v is -1/34.

Line w is parallel to line v. When 2 lines are parallel, they have the same slope.

The equation of w is:

y = -1/34 . x + b

Lines b passes through the point (-6, 10). We can replace this ordered pair in the previous equation to find the value of b.

10 = -1/34 . (-6) + b

b = 167/17

The equation of w is:

y = -1/34 . x + 167/17

Elise is measuring the angles of a triangle. She measures the first two and gets 30° and 100°. What should be the measure of the third angle?
A) 50°
B) 60°
C) 130°
D) 230°

Answers

The sum of angles in a triangle is 180°.
To obtain the third angle (let's call it x), we simply calculate thus:


30° + 100° + x = 180°

130° + x = 180°

x = 180° - 130°

x = 50° ... (A)

The measure of the third angle is 50 degrees for the given triangle. The correct answer would be an option (A).

What is a Triangle?

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.

Let x be the measure of the third angle.

As we know that the sum of interior angles in the triangle is always 180 degrees.

So, as per the given question, we have

30° + 100° + x = 180°

130° + x = 180°

x = 180° - 130°

Apply the subtraction operation, and we get

x = 50°

Thus, the measure of the third angle is 50 degrees.

what inequality represents the verbal expression? 8 less than a number n is less than 11

Answers

Final answer:

The inequality representing the verbal expression '8 less than a number n is less than 11' is written as 'n < 19'. This is found by adding 8 to both sides of the inequality 'n - 8 < 11'.

Explanation:

The inequality that represents the verbal expression '8 less than a number n is less than 11' can be translated into a mathematical inequality as follows. First, '8 less than a number n' means you take 8 away from n, which is written as n - 8. Then, this quantity being 'less than 11' is represented by the inequality n - 8 < 11. To find the range of values for n, we solve this inequality.

Step 1: Add 8 to both sides of the inequality to isolate n -
n - 8 + 8 < 11 + 8
Step 2: Simplify -
n < 19

Therefore, the inequality symbol that represents the verbal expression is n < 19.

The inequality that represents the verbal expression '8 less than a number n is less than 11' is 8 < n < 11. The symbol '<' represents 'less than' and since the number n is between 8 and 11, we use the inequality symbol '<' twice.

Final answer:

The inequality that represents the verbal expression '8 less than a number n is less than 11' is 11 > n - 8 > 8.

Explanation:

The inequality that represents the verbal expression '8 less than a number n is less than 11' is 11 > n - 8 > 8. This inequality states that the number n, decreased by 8, is greater than 8 and less than 11.

what does u stand for and could you make your answer a little clearer please?

Answers

From the information, it seems the runner is slowing down because the speed at 1st hour is 5km/h but at 3rd hour become 3km/h.

If v= velocity, v0= initial speed, t= time, and the a=acceleration then the function would be:
v= v0 + a * t

To find the acceleration you need to do this equation:
acceleration= velocity1- velocity3 / t3-t1
a = (3km/h-5km/h)/ (3 hour- 1 hour)
a = (-2km/h)/2hour= -1 km/hour^2

After that you need to find the initial speed. Try to put the 1st hour variable into the full equation. It would look like this
v= v0 + a * t
5km/h= v0 + (-1 km/hour^2 * 1 hour)
v0= 5km/h + 1km/h
v0= 6km/h 

Then the full function would be:
v= 6km/h - 1km/h^2 * t

What does it mean to say that a shape has an area of 8 square inches?

Answers

Final answer:

To say a shape has an area of 8 square inches means the shape covers 8 units of square inches. For similar shapes, the area comparison is the square of their scale factor; hence, if one shape's dimensions are twice another's, its area is four times larger.

Explanation:

When it is said that a shape has an area of 8 square inches, it means that the surface enclosed by the shape covers 8 units of square inches. In other words, you could fit 8 squares, each measuring 1 inch by 1 inch, inside the shape without overlapping or leaving any space inside the shape uncovered. To understand how the area of similar shapes compares, we can look into the problem involving two squares.

Marta has one square with a side length of 4 inches. A similar square has dimensions that are twice as large, meaning its side lengths are 8 inches. The area of the smaller square can be calculated as 4 inches x 4 inches, which equals 16 square inches. The area of the larger square would be 8 inches x 8 inches, resulting in 64 square inches. The ratio comparing the two areas is 64:16, which simplifies down to 4:1. This shows that the larger square's area is four times greater than that of the smaller square.

An area of 8 square inches means the shape covers a space equivalent to eight 1-inch by 1-inch squares.

To say that a shape has an area of 8 square inches means that the amount of space enclosed within the boundaries of the shape is equivalent to the area of eight 1-inch by 1-inch squares. Imagine a piece of graph paper where each small square is 1 inch by 1 inch.If the shape could be perfectly copied onto the graph paper, you would find that it covers eight of those squares.For example, an area of 8 square inches could be visualized by a variety of shapes: a rectangle measuring 2 inches by 4 inches or even an irregular shape that neatly fits inside the same area.In mathematics, there are various ways to calculate the area depending on the shape. For regular shapes like rectangles and circles, formulas are often used. But the fundamental idea of area — the measure of the space inside a shape — remains the same.

Jacqueline leaves city a at 2:00 p.m. and drives at a constant speed, traveling west on i-90. she passes city b, 40 mi from city a, at 2:50 p.m. (a) find a linear function d that models the distance (in mi) she has traveled after t min.

Answers

Final answer:

Jacqueline's speed is 0.8 miles per minute. The linear function representing the distance she has traveled in t minutes is d(t) = 0.8t. This equation means Jacqueline would have covered 0.8t miles after any given time t.

Explanation:

The subject of this question is a linear function in mathematics, more specifically, it is about the concept of speed and distance. The question describes the journey of a person named Jacqueline who is traveling at a constant speed.

Given that city B is 40 miles from city A and it took Jacqueline 50 minutes to cover that distance, we can easily calculate her speed. Speed = Distance / Time. Therefore, her speed is 40 miles / 50 minutes = 0.8 miles per minute.

The linear function d, which models the distance she has traveled after t minutes would, therefore, be d(t) = 0.8t. The coefficient 0.8 indicates the speed, and the variable t is the time spent traveling. So, after any given number of minutes t, Jacqueline would have covered 0.8t miles on her journey.

The diagram shows the floor plan of a one-bedroom apartment. Find the area of the living room in square feet. Round to nearest square foot.

Answers

The area of the living room is approximately 238 square feet.

To find the area of the living room, we need to multiply its length by its width.

First, let's convert the dimensions from feet and inches to feet. We have:

Length: 12 feet + 4 inches = 12 + 4/12 = 12.33 feet

Width: 19 feet + 4 inches = 19 + 4/12 = 19.33 feet

Now, we can multiply the length and width to find the area:

Area = length × width = 12.33 feet × 19.33 feet = 238.1289 square feet

Rounding to the nearest whole square foot, the area of the living room is approximately 238 square feet.

Please help me with this problem.

The diagram shows the floor plan of a one-bedroom apartment. Find the area of the living room in square feet. Round to nearest square foot.

The dimensions of living room are 12' 4" x 19' 4"

On rounding off to nearest feet we get the area of the living room as 238 ft²

In the figure it is given that the dimensions of the living room are 12' 4" x 19' 4". This means that the dimensions are:

12 ft 4 in x 19 ft 4 in

To get the area in feet, we need to convert the dimensions into feet. This can be done by using the conversion factor that 1 foot = 12 inch

So, 12 ft 4 in can be converted into feet as follows:

[tex]12\ \text{ft}\ 4\ \text{in} = 12\ \text{ft}\ + \frac{4}{12}\ \text{ft} = 12.333\ \text{ft}[/tex]

19 ft 4 in can be converted into feet as follows:

[tex]19\ \text{ft}\ 4\ \text{in} = 19\ \text{ft}\ + \frac{4}{12}\ \text{ft} = 19.333\ \text{ft}[/tex]

Now to calculate the area we multiply the dimensions of the living room (as the living room is a rectangle and area of rectangle is product of its length and breadth):

[tex]area = 12.333 \times 19.333 =238.433889[/tex] ft²

On rounding of to nearest feet we get the area as 238 ft². So, the area of the living room is 238 ft²
