If A is in the interior of NFL. If m/NFA = 5x+10, m/AFL = 30-2x, and m/NFL = 58°, the value of x would be 6

It is important to note that the formula for determining the sum of interior angles of a shape is expressed as;

(n-2) 180

Where 'n' is the number of sides

From the information given, we have that the shape has 3 sides, so we have

(3 -2)180

180°

Give the angles as;

Equate the angles to m/NFL, we have

5x+10 + 30-2x = 58

Now, collect like terms

5x - 2x = 58 - 40

Subtract like terms

3x = 18

Make 'x' the subject by dividing both sides by 3, we have

The percentage of the tip that Serena's father paid was 20%.

Mathematically, a percentage is a numerical ratio, usually expressed as a fraction of 100 and denoted by the percent sign (%).

Percentages show the proportional relationship between two fractions, like proportions and ratios.

The amount of the tip = $5

The cost of the ride = $25

The total amount paid by Serena's father = $30 ($5 + $25)

The percentage of tip to the ride's cost = The amount of the tip divided by the cost of the ride.

= 20% ($5/$25 x 100)

Thus, in percentage terms, the amount that Serena's father tipped the taxi driver is 20% of the ride's actual cost.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices.

10. In the given figure,

l ║m

(3x - 29)° + (8y + 17)° = 180° [Because they are linear pairs]

⇒ 3x -29 + 8y + 17 = 180

⇒ 3x + 8y - 12 = 180

⇒ 3x + 8y = 192 ............ (1)

Now,

8y + 17 = 6x -7 [Alternate interior angles]

⇒ 6x - 8y = 24 ..............(2)

On adding (1) and (2),

(3x + 8y) + (6x - 8y) = 192 + 24

simplifying the above equation, we get

⇒9x = 216

⇒ x = 216/9 = 24

⇒ x = 24

Now, 6x - 8y = 24

⇒ 8y = 6(24) - 24

⇒ y = (144 - 24)/8

⇒ y = 120/8 = 15

So, x = 24 and y = 15

11. In this given figure,

l ║m

7x - 23 = 49 + 3x ...... (Alternate interior angles)

⇒ 7x - 3x = 49+23

⇒ 4x = 72

⇒ x = 18

11y -1 = 3x [Alternate exterior angles]

⇒ 11y - 1 = 3 x 18

⇒ 11y = 54 + 1

⇒ 11y = 55

⇒ y = 5

Therefore, the value of x = 18 and y = 5

12. 11. In this given figure,

l ║m

3x - 4 = 5x - 38 [Alternate interior angles]

⇒ 5x - 3x = 38 - 4

⇒ 2x = 34

⇒ x = 17

7y - 20 + 5x - 38 + 90° = 180° [Angle sum property of a triangle]

⇒ 7y - 20 + 85 - 38 + 90 = 180

⇒ 7y + 117 = 180

simplifying the above equation, we get

⇒ 7y = 180 - 117

⇒ 7y = 63

⇒ y = 63/7 = 9

Therefore, the value of x = 17 and y = 9

The multiplication of the mixed fractions as 4²/₇ * 2¹/₅ gives; 9³/₇

A mixed fraction is one that has a part that is a whole number and a part that is a proper fraction.

Now, a proper fraction has its' numerator lesser than its' denominator while an improper fraction has it's numerator greater than its' denominator.

Let us convert each fraction into an improper fraction before multiplication.

4²/₇ = 30/7

2¹/₅ = 11/5

Thus, we have;

Answer:

45

Step-by-step explanation:

In this picture we can see that they gave us 2 angles.

Angle V has an angle of x+83

Angle S has an angle of 4x - 53

As one of the circle thermoses in mathematics said when there is an angle in the center of the circle, the angle at the circumference is half the angle at the center, which means we could create and equation such that:

angle of angle V = 2 times the angle of angle S

x + 83 = 2(4x - 53)

x + 83 = 8x - 106

189 = 7x

27 = x

Since we know x = 27, we can substitute into the equation angle of S to find what is the angle of TSU:

4x - 53

= 4(27) - 53

= 108 - 53

= 45

Answer:

<TSU = 55°

Step-by-step explanation:

We know that,

Angle at the circumference of a circle is twice the angle at the centre.

Therefore,

2 × <UST = <UVT

Given that,

< UVT = x + 83

< TSU = 4x - 53

Accordingly, we can make an expression like this.

[tex] \sf2 × <UST = <UVT[/tex]

[tex] \sf2(4x - 53) = x + 83 \\ [/tex]

And now solve the above expression and find the value of x.

Let us solve it now.

[tex] \sf8x - 106 = x + 83 \\ \sf8x - x = 106 + 83 \\ \sf7x = 189 \\ \sf \: x = 27[/tex]

And now, according to the question they've asked us to find the value of <TSU.

As we mentioned earlier, they've given that, <TSU = 4x - 53.

So, to find the value of Angle TSU, we have to replace x with 27 and find the value of angle TSU.

Let us solve it now

[tex] \sf \: <TSU = 4x - 53 \\ \sf \: <TSU = 4 \times 27 - 53 \\ \sf \: <TSU = 108 - 53 \\ \sf \: <TSU = 55 \degree[/tex]

The two solutions of the quadratic function are 0.58 and -1.1.

The solution of a quadratic equation can be obtained using the substitution method or formula method.

The solution of the given quadratic function is determined as follows;

f(x) = 8x² + 4x - 5

0 =  8x² + 4x - 5

The formula method of a quadratic function is given as;

[tex]x = \frac{-b \ \ \pm \ \sqrt{b^2 - 4ac} }{2a}[/tex]

from the above equation, a = 8, b = 4, c = -5

[tex]x = \frac{-4 \ \ \pm \ \sqrt{4^2 - 4(8\times -5)} }{2a}\\\\x = \frac{-4 \ \ \pm \ \sqrt{16 + 160} }{2(8)}\\\\[/tex]

x = 0.58 or -1.1

The Law of Large Numbers states that on the off chance that a test with an irregular result is repeated a huge number of​ times, the empirical probability of an event is likely to be near the true probability. The bigger the number of​ redundancies, the closer together these probabilities are likely to be.The law of large numbers does not ensure that a given test, particularly a little test, will reflect the genuine population characteristics or that a test that does not reflect the genuine population will be adjusted by a subsequent sample.

After thoroughly calculating the equation, we conclude that x⁴ + 4x³ - 6x² - 2x + 25  is the simplified form of 3/x - 1 - 4x - 1/x + 1 = x² +(5/x)²- 1 - 5

When the top and bottom of a fraction are the same size and still whole numbers, the fraction is said to be in its simplest form or simplified form.

Using 2/4 as an example, 1/2 can be written.

Simplify a fraction by multiplying its top and bottom by the biggest number that will divide them both exactly (they must stay whole numbers). the outcome will be what we call the simplified form.

We have been asked to simply the equation

3/x - 1 - 4x - 1/x + 1 = x² +(5/x)²- 1 - 5

⇒ 3/x - 4x - 1/x + 6 = x² +(5/x)²

⇒ 2/x - 4x + 6 = x² +(5/x)²

⇒ 2/x - 4x²/x + 6x/x = x² +(5/x)²

⇒ (2 - 4x² + 6x)/x = x² +(5/x)²

Multiplying x to both side

⇒ 2 - 4x² + 6x = x² +(5/x)² × x

⇒ 2 - 4x² + 6x = x³ + 25/x

​⇒  x³ + 4x² - 2 = 6x - 25/x

​⇒ x³ + 4x² - 2 = 6x²/x - 25/x

​⇒ x³ + 4x² - 2 = (6x²- 25)/x

Multiplying x to both side

​⇒ (x³ + 4x² - 2) x = 6x²- 25

​⇒ ​x⁴ + 4x³ - 2x = 6x²- 25
