5 (a) Calculate the sum of the interior angles of a polygon with 50 sides: (i)in degrees (ii) in right angles.​ help me solve it?

∠1 and ∠11 are corresponding angles.

The alternates interior angles are formed when the transversal line intersects the two  coplanar lines as the name the angles are interior to the figure and are alternative to each other as well.

Alternate exterior angles are at the opposite side of the transversal line and are at external to the figure or we can say that on outside boundaries of the figure.

These angles are the same side of any two of the parallel lines in the figure cut by the transversal line . They show a correspondence behavior with respect to each other.

When any of the two lines in figure are cut by a transversal line, then the pair of angles on any of the one side of the transversal  line and interior of  the two lines are called the consecutive interior angle.

According to given question ∠1 and ∠11 are corresponding angles.

y = 3.5x is the equation that represents y, the total number of hours Tonya works in x days if she continues at the given rate.

Unitary method is a concept in which the value of a single unit is first found out and then multiplied by the necessary value to get the required answer.

Here, we are given that Tonya works 3.5 hours in 1 day.

The total number of days = x

and the total number of hours Tonya works in x days = y

If she works for 3.5 hours in 1 day, in x days she will work-

x x 3.5

= 3.5x hours

Thus, y = 3.5x hours

Hence, y = 3.5x is the equation that represents Tonya's situation.

Answer :f(x) = -5x + 250

Step-by-step explanation:

* Lets  explain how to solve the problem

- In week 10 the manufacturer fixed 200 cars

- In week 15, the manufacturer fixed 175 cars

- the reduction in the number of cars each week is linear

- The form of the linear equation is y = mx + c, where m is the slope of

the line which represent the equation and c is the y-intercept

- The slope of the line m =

 where (x1 , y1) and (x2 , y2) are two points on the line

* Lets solve the problem

- Assume that the weeks' number is x and the cars' number is y

∴ (10 , 200) and (15 , 175) are two points on the line which represent

 the linear equation between the cars' numbers and the weeks

 numbers

∵ Point (x1 , y1) is (10 , 200) and point (x2 , y2) is (15 , 175)

∴ x1 = 10 , x2 = 15 and y1 = 200 and y2 = 175

- Use the rule of the slope above to find m

∴

- Substitute the value of x in the form of the linear equation above

∴ y = -5x + c

- To find c substitute x and y by one the coordinates of one of the

 two points

∵ x = 10 when y = 200

∴ 200 = -5(10) + c

∴ 200 = -50 + c

- Add 50 to both sides

∴ 250 = c

- Substitute the value of c by 250

∴ y = -5x + 250, where the number of cars seen each week is y and

 x is the number of the week

∵ f(x) = y

∴ f(x) = -5x + 250

As a single inequality, we can write the solution of the given compound inequality as → x ≥ 8.

There are two types of inequalities -

Strict inequalities : The inequalities that have < or > symbol between the L.H.S and R.H.S.

Slack inequalities : The inequalities that have ≤ or ≥ symbol between the L.H.S and R.H.S.

Given in the question are two inequalities as mentioned below -

-2x - 3 < -1   and   -2x - 3 ≤ -11

In this question → -2x - 3 < -1 is a strict inequality and -2x - 3 ≤ -11 is a slack inequality. We will solve them one by one.

Inequality - 1

- 2x - 3 < - 1

Add 3 on both sides -

- 2x - 3 + 3 < - 1 + 3

- 2x < 2

Multiply by -1/2 on both sides -

x > - 1

Inequality - 2

-2x - 3 ≤ -11

Add 3 on both sides -

-2x ≤ -8

Multiply by -1 on both sides -

2x ≥ 8

Divide by 2 on both sides -

x ≥ 8

Now, we have two inequalities -

x > - 1    and     x ≥ 8

We can write it as one equality -

x ≥ 8

Therefore, as a single inequality, we can write the solution of the given compound inequality as → x ≥ 8.

The value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

We are given the angle measurements as:

A = (6x - 35)°

B = (3x + 53)°

We need to solve for x and find the values of A and B

We know that co- interior angles are supplementary.

So, we get that:

A + B = 180°

Substituting the values of A and B in the above equation, we get that:

6 x - 35 + 3 x + 53 = 180

9 x + 18 = 180

9 x = 180 - 18

9 x = 162

x = 162 / 9

x = 18

So, we now get that:

A = (6x - 35)°

A = (6(18) - 35)°

A =(108 - 35)°

A = 73°

B = (3 x + 53)°

B = (3 (18) + 53)°

B = ( 54 + 53 )°

B = 107°

Therefore, we get that the  value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

Sn = a(1 - rⁿ)/(1 - r) is the formula for the sum of a finite number of terms in a geometric series, where is the number of terms, is the first term, and is the common ratio.

The sum of the finite geometric series Σ⁴ n=1 (1/2)ⁿ⁺¹ is 0.46875.

The equation be Sn = a(1 - rⁿ)/(1 - r), where s exists the total, a1 exists the series first term, and r exists the common ratio, is a general formula for estimating the sum of an finite geometric series. The formula a2/a1, where a2 is the second term in the series and a1 is the first term in the series, can be used to determine the common ratio.

Let the sum of the finite geometric series be Σ⁴ n=1 (1/2)ⁿ⁺¹

Σ⁴ n=1 (1/2)ⁿ⁺¹ = (1/2)¹⁺¹ + (1/2)²⁺¹ +(1/2)³⁺¹ + (1/2)⁴⁺¹

simplifying the above equation, we get

= (1/2)² + (1/2)³ + (1/2)⁴ + (1/2)⁴⁺¹

= (1/4) + (1/8) + (1/16) + (1/32)

Where, the first term is a = 1/4

common ratio be r = 1/2

There are 534 played games in total.

There are 24 teams, and each team plays 2 matches against each one of the other teams.

So, let's say that each team is called team 1, team 2, team 3, ..., team 24.

If we start with team 1, they will play 2 games with each one of the other 23 teams, so here we will have: 23*2 = 46 games.

Now we go to team 2, we already counted the 2 games that the played with team 1, so we only look at the remaining 22 teams, here we will have:

22*2 = 44 more games.

Now with team 3, there are 21 teams remaining, so here we add another 2*21 = 42 games

This is the explanation

The statement is sometimes true.

The given statement is ' The geometric mean for two positive integers is another integer.'

Geometric mean of two integers is the square root of their product.

If a and b are two integers, then geometric mean = [tex]\sqrt{ab}[/tex]

Its value need not be an integer always. In some cases the statement fails.

For example, let a = 3 and b = 6

Then geometric mean = [tex]\sqrt{3 \times 6} = \sqrt{18}[/tex] = 4.24, which is not an integer.

Now if a and b are equal numbers, we will get an integer as the geometric mean. Because then their product will be a perfect square and taking square root, we get the same number as the geometric mean.

Also consider a = 9 and b = 4

Then their geometric mean = [tex]\sqrt{36}[/tex] = 6

5c - 2y = -27

Therefore, using elimination method, the equation can be solved as follows:

multiply equation(ii) by 1.5(3  /2)

-3c - 3y = -9

7.5c - 3y = - 40.5

subtract equation(i) from equation(ii)
