Measure of each interior angle of 28 sided polygon

[tex] \frac{(28 - 2) \times 180 \degree}{28} \\ \\ = \frac{26 \times 180 \degree }{28} \\ \\ = \frac{4680 \degree }{28} \\ \\ = 167.14\degree \\ [/tex]

The measure of each interior angle of a regular 28-gon is 167.14 degrees.

The measure of each interior angle of a regular 28-gon can be calculated using the formula:

Interior Angle = (n-2) * 180 / n

Substitute n = 28 into the formula:
Interior Angle = (28 - 2) * 180 / 28 = 24 * 180 / 28 = 167.14 degrees

Final answer:

After accounting for the flight duration of 3 hours and 6 minutes and the one-hour time difference due to the Central Standard Time Zone, Doris will arrive in Houston at 12:11 p.m. local time.

Explanation:

Doris is taking a flight from New York to Houston, and we need to calculate the local time of her arrival in Houston after a 3-hour-6-minute flight. To find the answer, we must account for the time zone difference and the duration of her flight. New York is in the Eastern Standard Time Zone, while Houston is in the Central Standard Time Zone, which is one hour behind New York.

Starting from a departure time of 10:05 a.m. in New York, we first add the flight duration which is 3 hours and 6 minutes. This gets us to 1:11 p.m. New York time. Since Houston is one hour behind New York, we subtract one hour from this time to get the local time in Houston, which will be 12:11 p.m.

The correct answer is D. 12:11 p.m. This is the time Doris will arrive in Houston, local time.

Answer:

A x=3.1

Step-by-step explanation:

1/2(4x+6)=-5x+24.7

Multiply each side by 2 to get rid of the fraction

2*1/2(4x+6)=2(-5x+24.7)

4x+6 = -10x +49.4

Add 10x to each side

4x+6+10x=-10x+10x+49.4

14x +6 = 49.4

Subtract 6 from each side

14x+6-6 = 49.4-6

14x = 43.4

Divide each side by 14

14x/14 = 43.4/14

x = 3.1

Answer:

12.50

Step-by-step explanation:

The expected amount is $12.50.

The Probability in mathematics is possibility of an event in time. In simple words how many times that incident is happening in any given time interval.

There are 8 possibilities, if coin is flipped three times.

HHH, HHT, HTH, TTH, HTT, THT and TTH,

where H is possibility of head and T is tail.

Now the probabilities,

0 tails: 1 way out of 8 total: P(0) = 1/8

1 tails: 3 ways out of 8 total: P(1) = 3/8

2 tails: 3 ways out of 8 total: P(2) = 3/8

3 tails: 1 way out of 8 total: P(3) = 1/8

The expected amount;

(1/8)X 0 + (3/8)X 5 +(3/8)X15 +(1/8)X40

= 15/8 + 45/8 + 40/8

= 100/8

= 12.50

Therefore, the expected amount is $12.50.

Answer:

2/3   or 0.6

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

According to the question,10/27÷5/9

So we will have to be careful when solving this kind of question

So let's solve

10/27÷5/9

To solve we will have to convert the division to multiplication and during this process the 5/9 will actually change to 9/5

10/27×9/5

If you calculate it well,you will get

2/3

Which means that the final answer is 2/3 since it cannot be solved further

So 10/27÷5/9 gives 2/3

It takes 2 seconds to reach a maximum height of 69 feet, and the range is [5, 69].

The equation is of the form

h(t) = -16t² + v₀t + h₀, where -16 is the gravitational constant, v₀ is the initial velocity, and h₀ is the initial height.  Using the values from our problem, we have:

h(t) = -16t² + 64t + 5

To find the maximum height, we find the vertex.  The first step in this is to find the axis of symmetry, which is given by -b/2a:

-64/2(-16) = -64/-32 = 2

This is our value for t, so it takes 2 seconds to reach the maximum.  Substituting this into our function, we have

h(2) = -16(2²) + 64(2) + 5 = -64 + 128 + 5 = 64 + 5 = 69

This is the maximum height.

The range of heights goes from 5 to 69, inclusive, or [5, 69].  

The T-Shirt reaches its maximum height of 104 feet at 2.5 seconds. The range of the height over time is from 4 feet to 104 feet.

To analyze the projectile motion of the T-Shirt, we'll use the kinematic equations. The height h(t) at any time t can be modeled by the equation:

h(t) = -16t2 + v0t + h0

where:

1. Time to reach maximum height:

To find the time to reach maximum height, we use the formula for the time at which the velocity becomes zero:

t = v0 / g

t = 80 ft/s / 32 ft/s2 = 2.5 s

2. Maximum height:

Now, substituting t = 2.5 s into the height equation, we get:

h(2.5) = -16(2.5)2 + 80(2.5) + 4

h(2.5) = -100 + 200 + 4 = 104 feet

3. Range of the height function:

The T-Shirt starts at 4 feet, reaches a maximum of 104 feet, and is caught at 35 feet. Hence, the range of the height function is [4, 104] feet.

The equation of the line is [tex]y=\frac{-1}{5} x-\frac{21}{5}[/tex].

Slope of the line:

 [tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

 [tex]$m=\frac{-5-(-3)}{4-(-6)}[/tex]

 [tex]$m=\frac{-5+3}{4+6}[/tex]

 [tex]$y-(-3)=\frac{-1}{5}(x-(-6))[/tex]

 [tex]$y+3=\frac{-1}{5}(x+6)[/tex]

 [tex]$y+3=\frac{-1}{5} x-\frac{6}{5}[/tex]

Subtract 3 from both sides of the equation.

[tex]$y=\frac{-1}{5} x-\frac{21}{5}[/tex]

The measure of angle E is 75°.

Solution:

Given data:

∠E = 5x, ∠F = 7x – 13 and ∠R = –2 + 6x

A quadrilateral inscribed in a circle is called cyclic quadrilateral.

∠R and ∠G are opposite angles in a cyclic quadrilateral.

In cyclic quadrilateral, opposite angles are supplementary.

⇒ m∠R + m∠F = 180

⇒ –2 + 6x + 7x – 13 = 180

⇒ 13x – 15 = 180

Add 15 from both sides of the equation, we get

⇒ 13x = 195

Divide by 13 from both sides of the equation, we get

⇒ x = 15

To find the measure of angle E:

m∠E = 5x

m∠E = 5(15)

m∠E = 75

The measure of angle E is 75°.

Note that for graph, Y = mx + c, where m = slope of graph and c = y-intersect

1) equation of line: y = [tex]-\frac{3}{4} x[/tex] + 4         ∴ m = -3/4 ,  c = 4

2) equation of line: y = [tex]\frac{3}{2} x[/tex] + 3              m = 3/2 ,   c = 3

3) equation of line: y = [tex]-\frac{2}{5} x[/tex] - 2            m = -2/5 ,  c = -2

4) equation of line: y = [tex]\frac{1}{2} x[/tex] + 3              m = 1/2 ,     c = 3

5) equation of line: y = -x + 2               m = -1 ,       c = 2

6) equation of line: y = [tex]-\frac{5}{2} x[/tex] - 1             m = -5/2 ,   c = -1

Step-by-step explanation:

For each of the line equations, "m" is the slope which is also dy/dx. Also the intersect "c" is on the y axis(Vertical line).

For each equation, assume a number for 'x' then solve for y.... you will be able to get coordinates (x,y) for each graph.

Using 1) as example:

1) equation of line: y = [tex]-\frac{3}{4} x[/tex] + 4         ∴ m = -3/4 ,  c = 4

at intersection 'c', y = 4, when x = 0

∴ y = -3/4 (1) + 4  = [tex]3\frac{1}{4}[/tex]

repeat for x = 2, 3, 4, 5, 6

Do same for equation line 2, 3, 4, 5, 6 to get coordinates to plot each graph

Answer:

23pi, or approx. 72.27

Step-by-step explanation:

circumference = 2(pi)r, or 2d

pi = approx. 3.14, r = radius, and d = diameter

You are given diameter, so all you have to do is multiply 23 feet by pi.

The circumference of the clock face of is 72.1 feet or 23π.

Given that the diameter of the clock face is 23 feet.

To calculate the circumference of the clock face, use the the following formula:

The value of π is approximately 3.14159.

Circumference = 2πr

In the formula r is the radius.

Since, the diameter is 23 and the radius is half of the diameter.

Thus, the radius r is 11.5.

Further, calculate the circumference:

Circumference = 2 × 3.14159 × 11.5

Circumference ≈ 72.08357

Circumference ≈ 72.1 feet

Therefore, the circumference of the clock face is 72.1 feet.
