the poles for a tent form vertices of a regular decagon. when the poles are properly positioned, what is the measure of the angle formed at a corner of the tent. ( n - 2 ) × 180

Answers

Answer 1

Answer:

Each Interior Polygon angle = 180 - [ 360 / number of sides]

Each Angle = 180 - [ 360 / 10]

Each Angle = 180 - 36

Each Angle = 144 degrees

area exact side length estimite side length
100 square units ------ units
95 square units bettween ----- and -----
36 square units -------units
30 square units bettween ----- and -----

Answers

Given:

The area of the squares are given.

To find:

The exact side length or estimate side length of the square.

Solution:

We know that, the area of a square is

[tex]A=a^2[/tex]

Where, a is the side length of the square.

[tex]a=\sqrt{A}[/tex]

Area of the square is 100 square units. So, the side length is:

[tex]a=\sqrt{100}[/tex]

[tex]a=10[/tex]

Therefore, the side length is 10 units.

Area of the square is 95 square units. So, the side length is:

[tex]a=\sqrt{95}[/tex]

It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].

Therefore, the side length is between 9 and 10.

Area of the square is 36 square units. So, the side length is:

[tex]a=\sqrt{36}[/tex]

[tex]a=6[/tex]

Therefore, the side length is 6 units.

Area of the square is 30 square units. So, the side length is:

[tex]a=\sqrt{30}[/tex]

It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].

Therefore, the side length is between 5 and 6.

Mark buys Apple stock for $100 and its value increases by a factor of 1.5 each week. Which equation represents the relationship between the number of weeks past since purchase, t, and the current value of the stock, V?

Answers

Given:

Initial value of the stock = $100

Growth factor = 1.5 each week.

To find:

The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.

Solution:

Let V be the current value of the stock after t week.

The exponential growth model is:

[tex]V=ab^t[/tex]

Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.

Substituting [tex]a=100,b=1.5[/tex], we get

[tex]V=100(1.5)^t[/tex]

Therefore, the required equation for the given situation is [tex]V=100(1.5)^t[/tex].

PQ and QR are 2 sides of a regular 12-sided polygon.
PR is a diagonal of the polygon.

Work out the size of angle PRQ.
You must show your working.

Answers

The size of the angle m∠PRQ for the polygon is equal to 15°

How to calculate for the angle PQR using interior angle of the polygon

To calculate the sum of interior angles of a polygon, you can use the following formula:

Sum of interior angles = (n-2) x 180 degrees

Where "n" represents the number of sides (or vertices) of the polygon.

Given the 12 sided polygon;

(12 - 2) × 180 = 1800

one interior angle = 1800/12 = 150°

The angle PQR is a base angle of the Isosceles triangle ∆PQR with one interior angle of the 12-sided polygon so;

m∠PRQ = (180 - 150)/2

m∠PRQ = 15°.

Therefore, the size of the angle m∠PRQ for the polygon is equal to 15°

b Pete won the first heat in 13 minutes 39 seconds. Jacob won the second heat in 14 minutes 16 seconds. Who ran faster? By how much? t​

Answers

In accordance with the research problem we were given, Pete outran Jacob by 37 seconds.

A second of angle is what?

Minutes are the 60 equal pieces that make up each degree. Thus, 7 to 8 inches can also be written as seven degrees and thirty minutes, or seven°30'. For example, 2 ° 5 minutes and 30 seconds are represented by the notation 2° 5' 30 since each minutes is further subdivided into 60 equal seconds.

Then, we have Pete's time: First, we convert minutes into seconds. 13 minutes and 39 seconds is equal to 13 * 60 + 39, or 819 seconds.

Jacob's period: 14 minutes and 16 sec. = 14 * 60 + 16 sec. = 856 sec.

Jacob outpaced Pete by 856 – 819 = 37 seconds.

Pete ran 37 seconds faster as a result.

Anita needs to construct ten cones for a class project. How many square feet of material will she need? Use 3.14 for π. Enter your answer in the box. Th radius is 6 ft and the height is 12 ft.

Answers

Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√ (h²+r²), where r is the radius and h is the height.

r = 6 ft / 2 = 3 ft

Solving for the lateral surface area of one cone:

LSA = (3.14) (3) [√ (12²+3²) ] = 116.52 sq ft.

Since she needs 10 cones:

10 * 116.52 sq. ft = 1,165.2 sq ft.

She will need 1,165.2 sq ft of material.

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given data ,

Let the mixed number equation be represented as A

Now , the value of A is

To solve each equation, we can convert mixed numbers to improper fractions, then multiply the fractions, and simplify the result if possible.

A)

A = 5/6 × 4 2/3 = (5/6) × (4×3 + 2)/3

A = (5/6) × 14/3 = 35/9, which is not equal to 3 8/9.

Therefore, equation A is false.

B)

B = 1 1/10 × 8 3/5 = (11/10) × (43/5)

B = 473/50 = 9 23/50, which is not equal to 9 1/2.

Therefore, equation B is false.

C)

C = 3 2/9 × 2 1/6 = (29/9) × (13/6)

C = 377/54 = 6 53/54

Therefore, equation C is true.

D)

D = 2 3/7 × 1 7/8 = (17/7) × (15/8)

D = 255/56 = 4 23/56 = 2 3/8

Therefore, equation D is true.

E)

E = 7/12 × 4 = 7/3 = 2 1/3

Therefore, equation E is true.

Hence , the equations that are true are C, D, and E
