Formula to find interior angles of regular polygon=(n-2)180×n

N= number of sides

in figure sides are 5

So,

(5-2)×180

3×180

540 Answer

Answer:

108°

Step-by-step explanation:

Measure of each interior angle

[tex] = \frac{(n - 2) \times 180 \degree}{n} \\ \\ = \frac{(5 - 2) \times 180 \degree}{5} \\ \\ = \frac{3\times 180 \degree}{5} \\ \\ = \frac{540\degree}{5} \\ \\ = 108 \degree[/tex]

Answer:

If 34.54 is the diameter then 17.27 is the radius

Step-by-step explanation:

34.54 ÷ 2 = 17.27

the answer would be 1500

Answer:

Step-by-step explanation:

Here,

[Taking 'A' = 'a']

[tex]a \: = \: 4\pi {r}^{2} [/tex]

Then for 'r',

[tex] = > 4\pi {r}^{2} = a[/tex]

[tex] = > {r}^{2} = \frac{a}{4\pi} [/tex]

[tex] = > r = \sqrt{\frac{a}{4\pi} }[/tex]

[tex] = > r = \frac{1}{2}\sqrt{ \frac{a}{\pi} } [/tex]

Hence,

Option C is correct .

Answer:

There is no graph but I can infer that if time is on the x axis it would be C and if distance is on the x axis it would be B

Step-by-step explanation:

Answer:

98 degrees

Step-by-step explanation:

HJ = (5x - 7)

Because it's a full circle:

61 + 34 + (5x - 7) + (9x - 22) = 360

95 + (14x - 29) = 360

14x = 360 - 95 + 29 = 294

x = 21

HJ = 5x - 7 = 5 * 21 - 7 = 105 - 7 = 98

Answer:

(5.5,2)

Step-by-step explanation:

Find the midpoint of the segment with the following endpoints (7-6) and (4-10)

The formula for calculating the x and y coordinate is expressed as

X = x1+x2/2

X = 7+4/2

X = 11/2

X = 5.5

Y = y1+y2/2

Y = -6+10/2

Y = 4/2

Y = 2

Hence the required midpoint is at (5.5,2)

Answer:

(5.5, -8)

Answer:

mean means average so I think i should have first add all the numbers then divide by the number of the numbers I think that's the method if you don't see it correct then it's alright but I believe it's correct.

Step-by-step explanation:

3x+11=57

subtract 11 from both sides and you will get this

3x=46

Divide by 3

42/3. 3/3

X=14

Answer:

15.333

Step-by-step explanation:

3x+11=57(y)

reverse the question

so:

57-11=46

46 divided by 3=15.333

so x=15.333

Step-by-step explanation:

Mean = Σxn/n

Σx/n = ((2 × 4) + (3 × 5) + (4 × 6) + (5 × 3) + (6 × 3) + (7 × 0) + (8 × 1))/(4 + 5 + 6 + 3 + 3 + 0 + 1)

Σx/n = 88/22

Answer:

31.25 is the answer at your question

Answer:

[tex]Pr = 32.49\%[/tex]

Step-by-step explanation:

Given

Let E represents the event of wearing glasses or contacts.

So;

[tex]P(E) =57\%[/tex]

Required

The probability that selected 2 wears glasses

This is calculated as:

[tex]Pr = P(E)\ and\ P(E)[/tex]

[tex]Pr = P(E)\ *\ P(E)[/tex]

[tex]Pr = 57\% * 57\%[/tex]

[tex]Pr = 0.57 * 0.57[/tex]

[tex]Pr = 0.3249[/tex]

[tex]Pr = 32.49\%[/tex]

Answer:

The missing number is 21

Step-by-step explanation:

-12 + X = 9

X = 9 + 12

X = 21

Answer:

x=42

Step-by-step explanation:

Write the equation.

2(x+50)=16+4x

Spread the parentheses

2x+100=16+4x

Put variables on one side, numbers on the other.

2x-4x=16-100

Add/subtract/multiply/divide the variables with variables and numbers with numbers.

-2x=-84

Make x alone

-x=-42

Flip sides to make x positive

42=x

Answer:

$128,500

Step-by-step explanation:

Find out how much he will earn from his 1st year to 24th.

1st year = 48000

2nd year = 48000 + 3500 = 51500

3rd year = 51500 + 3500 = 55000

4th year = 55000 + 3500 = 58500

5th year = 58500 + 3500 = 62000

6th year = 62000 + 3500 = 65500

7th year = 65500 + 3500 = 69000

8th year = 69000 + 3500 = 72500

9th year = 72500 + 3500 = 76000

10th year = 76000 + 3500 = 79500

11th year = 79500 + 3500 = 83000

12th year = 83000 + 3500 = 86500

13th year = 86500 + 3500 = 90000

14th year = 90000 + 3500 = 93500

15th year = 93500 + 3500 = 97000

16th year = 97000 + 3500 = 100500

17th year = 100500 + 3500 = 104000

18th year = 104000 + 3500 = 107500

19th year = 107500 + 3500 = 111000

20th year = 111000 + 3500 = 114500

21st year = 114500 + 3500 = 118000

22nd year = 118000 + 3500 = 121500

23rd year = 121500 + 3500 = 125000

24th year = 125000 + 3500 = 128500

Answer: Tell me if i am wrong

The answer is 'The slope of g(x) is less than the slope of f(x)'  

Step-by-step explanation:

Given the graphs of f(x) and g(x). we have to compare the slops of these two.

The graph of f(x) passes through the points (1,0) and (2,2)

∴ The slope of [tex]f(x) = \frac{y2-y1}{x2-x1}=\frac{2-0}{2-1} = 2[/tex]

The graph of g(x) passes through the points (0,2) and (2,3)

∴ The slope of [tex]g(x)=\frac{y2-y1}{x2-x1} =\frac{3-0}{2-0} =\frac{1}{2}[/tex]

As [tex]\frac{1}{2} <2[/tex]

This shows that the

The slope of g(x) is less than the slope of f(x).

Answer:

x=7/2 and x=-2/7

Step-by-step explanation:

By the Zero Product Property, we will set both expressions equal to 0 and solve:

p(x) = (2x-7)(7x+2)

0 = (2x-7)(7x+2)

2x-7=0 and 7x+2=0

2x=7 and 7x=-2

x=7/2 and x=-2/7

The factors of the polynomial are (2x – 7) and (7x + 2). Then the zeroes will be 7/2 and negative 2/7.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The polynomial is given below.

p(x) = (2x – 7)(7x + 2)

Then the zeroes of the polynomial will be

The factor of the polynomial is already given. Then the zeroes will be

x = 7/2, -2/7
