Two of the interior angles of a polygon are 140° and 160° , the remaining and 150°. Find the number of sides of the polygon​

Answers

the number of sides of the polygon​ 12 sides

Which polygon has a space inside?

An interior angle is a shape's internal angle. The closed shape with sides and vertices is a polygon. All of the inner angles of a regular polygon are equal to one another. For instance, a square has interior angles that are all exactly right angles, or 90 degrees.

In a regular polygon, all internal angles are equal. Interior angle of a polygon = sum of interior angles number of sides is the formula for determining the amount of an interior angle.

The n-sided polygon's inner angle total equals (n-2).

180°, thus as follows:

140°+160°+ (n-2)150 = (n-2)180°

or, 300° = (n-2)(180° - 150°).

or, 300° = (n-2) 30°

or, 10= n - 2.

alternately, n = 10 + 2 = 12 sides.

The value of x is 13 and the angles in the triangle are 38,69 and 73 respectively.

What is triangle ?

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

From the given figure,

In the given triangle ,

The triangles are 3x - 1 , 8x - 35  and 6x - 5

The sum of all angles is always is 180 degrees.

so,

we get,

3x - 1 + 8x - 35 + 6x - 5 = 180

17x - 41 = 180

17x = 180 + 41

17x = 221

x = 221 / 17

x = 13

so,

3x - 1  = 3*13 - 1 = 38

8x - 35  = 8* 13 - 35 = 104 - 35 = 69

6x - 5 = 6*13 - 5 = 78 - 5 = 73

Therefore, The value of x is 13 and the angles in the triangle are 38,69 and 73 respectively.

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?
$

Answers

The discounted price of the set of dishes would be = $63.89

How to calculate the discounted price?

The original cost of the dishes = $57.68

The percentage increase of the cost of the dishes = 125%

That is,

= 125/100 × 57.68

= 7210/100 = $72.10+57.68 = $129.78

After one month, the store marked it down by 50%, therefore the discounted price;

= 50/100 × 129.78/1

= 6489/100

What is Law of Sines?

Law of sines is a law in trigonometry which states that the ratios of the angle to the opposite side of a triangle are equal.

For triangle ABC,

sin A / a = sin B / b = sin C / c

where a, b and c are the sides opposite to the angles A, B and C respectively.

Here,

∠B = 112° 10' = 112° + 0.167° = 112.167°

∠C = 15° 20' = 15° + 0.333° = 15.333°

By the angle sum property of triangle,

∠A = 180° - (∠B + ∠C)

∠A = 180° - (112.167° + 15.333°)

     = 52.5°

Using law of sines,

sin A / BC = sin C / AB

sin (52.5°) / 354 = sin (15.333°) / AB

AB = [354 × sin (15.333°)] / [sin (52.5°)]

AB =  [354 × 0.264] / [0.793]

AB = 117.992 meters

If f(1) = 5 and f(n) = 5f(n-1) + 5 then find the value of f(3)

Answers

The value of function for f(5) is 3125.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given that, f(1) = 5 and f(n) = 5f(n − 1)

Now, for finding the the 5th term we have to find the remaining four term before the 5th term.

So, n=2

f(2) = 5f(1)

f(2)=  5(5)

f(2)=  25

Now, n=3

f(3) = 5f(2)

f(3)=  5(25)

f(3)=  125

Now, n=4

f(4) = 5f(3)

f(4)=  5(125)

f(4)=  625

Now, n=5

f(5) = 5f(4)

f(5)=  5(625)

f(5)=  3125

Hence, the value of function for f(5) is 3125.

The solutions of the equation are x < 18 and x < - 30.  

Solution on inequalities:  

Solutions of equations are the numerical values of the variables that will satisfy the condition in the given equation. Similarly, the solutions of inequalities are the values of variables that can satisfy the given inequality.

We can solve an inequality by adding or subtracting the same integer on both sides, or we can multiply or divide by the same number on both sides until we get the value of 'x'.

Here we have

3/4 |1/3x + 2| < 6  

We can solve the above equation as follows

3/4 |1/3x + 2| < 6    

Multiply by 4 on both sides

=> 4 [ 3/4 |1/3x + 2| ] < 4 × 6    

=>  3 |1/3x + 2| < 24  

=> | x + 6| < 24      

=> x + 6 < ± 24      

=> x + 6 < 24      and     x + 6 < - 24

Subtract - 6 on both sides

=> x + 6 - 6 < 24 - 6      and     x + 6 - 6 < - 24 - 6

=> x < 18       and       x < - 30

Worker B: 4, 8, 1, 9, 2, 9, 4, 3

Both workers averaged 5 parts per hour. Which worker has the higher variance and standard deviation?

Answers

The worker B has a higher variance of σ² = 9 and standard deviation of 3

What is Standard Deviation?

The standard deviation refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Standard Deviation is calculated by

Each number's deviation from the mean must be determined, and then squared.

Next, add up all of these values.

Divide the result by the quantity of numbers.

Then calculate its square root.

Given data ,

Let the data of worker A = { 5, 4, 4, 6, 7, 5, 6, 3 }

Let the data of worker B = { 4, 8, 1, 9, 2, 9, 4, 3 }

Now , the mean of worker A = 5

The mean of worker B = 5

So , the standard deviation of worker A is calculated as

The sum of the difference of the data from mean is

SD = √ ( 5 - 5 )² + ( 5 - 4 )² + ( 5 - 4 )² + ( 5 - 6 )² + ( 5 - 7 )² + ( 5 - 5 )² + ( 5 - 6)² + ( 5 - 3 )² / 8

On simplifying the equation , we get

SD = √ ( 12/8 )

SD = √1.5

Standard deviation σ = 1.2247449

And , the variance of worker A is σ² = 1.5

Now ,

The standard deviation of worker B is calculated as

The sum of the difference of the data from mean is

SD = √ ( 5 - 4 )² + ( 5 - 8 )² + ( 5 - 1 )² + ( 5 - 9 )² + ( 5 - 2 )² + ( 5 - 9 )² + ( 5 - 4)² + ( 5 - 3 )² / 8

On simplifying the equation , we get

SD = √ ( 72/8 )

SD = √9

Standard deviation σ = 3

And , the variance of worker A is σ² = 9

Mayra's brother is driving back from college to visit. His college is 330 miles away. After an hour of
driving, he still has 275 miles to go. If the roads are clear, he'll be able to keep up that pace for the
whole drive. Write a linear function to model how much further he'll have to go over time.

Answers

The linear function to model how much further he'll have to go over time is h(t) = 330 - 55t

How to write a linear function?

Total distance between home and college= 330 miles

Distance remaining to cover= 275 miles

Distance covered= Total distance between home and college - Distance remaining to cover

= 330 miles - 275 miles

= 55 miles

Time taken to cover 55 miles= 1 hour

h(t) = 330 - 55t

Where,

h = distance remaining to cover

t = time

Ultimately, h(t) = 330 - 55t is the linear function which represents how much further he'll have to go over time.

(enter only one word.) LAB: SOIL PARTICLESYou have learned that soil is made of weathered rock, water, air, and organic material. The size of particles is an important soil characteristic. According to the United States Department of Agriculture (USDA), there are three main particle sizessand, silt, and clay. Clay is particles smaller than 0.002 mm. Sand is particles larger than 0.05 mm. Particles in between are silt. The size of particles in soil determines how much water the soil will hold. Small particles hold more water than large particles.Soil usually settles into different layers called horizons. The arrangement of horizons is the soil profile. In this experiment, you will observe how particle size affects the soil profile.Describe how particle size affects the settling of soil.Which type of soil do you think will settle to the bottom of the container faster?1 1/2 cups potting soil1 1/2 cup sand3 wide-mouthed juice bottles with lidsMasking tapePenWaterMake masking tape labels for each juice bottle.
