Answer:

The missing side is X=4

Step-by-step explanation:

Since the triangles are similar to eachother, they will have the same ratio.

One way to solve is dividing 8 by 2. Since 12 divided by 2 is 6,

we can expect 8 divided by 2 to be the missing side we are looking for.

Hope that helps!

Answer:

x = 4

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{x}{8}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )

12x = 48 ( divide both sides by 12 )

x = 4

Step-by-step explanation:

If 24 muffins cost 46$ how much does 1 muffin cost?

46 : 24 =

1,916666666666667$

(the total cost is 46$ or 48? are you sure?)

Hey there!

It costs about $46 for 24 muffins, so in order to find out the total cost for 1 muffin you have to DIVIDE 46 from 24 or 24 from 46.

So, lets first divide 46 from 24

46 / 24

= 46 ÷ 24

= 46 ÷ 2 / 24 ÷ 2

= 23 / 12

= 1.916667

≈ 1.92

Therefore, your answer is: $1.92

Good luck on your assignment & enjoy your day!

Step-by-step explanation:

Answer:

R=50    b=130   a=135

Step-by-step explanation:

Sum of Internal angles   = 180

R= 180-85-45 = 50

missing interior angle R  = 50

If a side of a triangle is produced, then the exterior angle that is  formed is equal to the sum of the two interior opposite angles.

P+Q = 85+45= 130     b=130

P+R = 85+50 = 135     a=135

To solve this problem, we would have to add the sum of angles in a triangle and then find the missing side. Furthermore, value of R, a and b are 50°, 135° and 130° respectively.

Data;

The sum of angles in a triangle is equal to 180° and we can find the missing side on R.

[tex]P+Q+R = 180^0\\85^0+45^0+R = 180^0\\130^0+R=180^0\\R = 180 - 130 \\R = 50^0[/tex]

Since we know the value of R and Q, we can proceed to find a and b.

[tex]Q+ a = 180\\[/tex]

The reason behind this is that the sum of angles on a straight line is equal to 180^0

[tex]45+a = 180 \\a = 180 - 45 \\a = 135^0[/tex]

Now let's find the value of b

[tex]R + b = 180\\R = 50^0\\50 + b = 180\\b = 180 - 50 \\b = 130[/tex]

From the calcuations above, the value of R, a and b are 50°, 135° and 130° respectively.

The value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial equation in the problem is,

[tex]2x^3 +18x^2 - 18x - 162[/tex]

The factor of the polynomial equation are given as,

[tex]2(x+ k)(x - k)(x +9)[/tex]

First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.

Take out the highest common factor 2, which can divide each term of the above equation (2, 18, -18, -162). Thus,

[tex]2(x+ k)(x - k)(x +9)=2(x^3 +9x^2 - 9x - 81)[/tex]

Take out the highest common factor to make the groups as,

[tex]2(x+ k)(x - k)(x +9)=2(x^2( x+9) - 9(x + 9))\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 9)\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 3^2)[/tex]

Use the property of difference of the square for the (x²-3²) term as,

[tex]2(x+ k)(x - k)(x +9)=2( x+9) (x+3)(x-3)\\2(x+ k)(x - k)(x +9)=2 (x+3)(x-3)( x+9)[/tex]

On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.

not solutions: 10 2/3 and 129

Step-by-step explanation:

Let's solve the inequality first

[tex]20 \geqslant 5 + 3x \\ 20 - 5 \geqslant 3x \\ 15 \geqslant 3x \\ 5 \geqslant x[/tex]

so solution set must contain all the values that are less than equal to 5.

-15 and 4 3/4 are less than 5

so these are solutions.

Using the expected value of a discrete distribution, it is found that the amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

In this problem, considering 6 out of 6^2 = 36 outcomes are doubles, we have that the distribution is:

P(X = 5) = 1/6.

P(X = x) = 5/6.

A fair game means that the expected value is of 0, hence:

[tex]5\frac{1}{6} - \frac{5x}{6} = 0[/tex]

[tex]\frac{5x}{6} = \frac{5}{6}[/tex]

[tex]x = 1[/tex]

The amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.

Answer:

∠TVX = 49°

x = 52°

x = 57.5°

BC = 6 cm

Step-by-step explanation:

Question 1

Angle at the Centre Theorem:

∠UTV = 1/2 ∠UOV = 134 ÷ 2 = 67°

Angles around a point add up to 360°

⇒ interior angle of ∠UOV = 360 - 134 = 226°

The sum of interior angles of a non-cyclic quadrilateral is 360°

⇒ ∠OVT = 360 - 26 - 226 - 67 = 41°

As WVX is a tangent, it forms a right angle with the radius (OV)

⇒ ∠TVX = 90 - 41 = 49°

Question 2

Angles on a straight line add up to 180°

The angle between a tangent and a chord is equal to the angle in the alternate segment.

Therefore ∠x = 180 - 68 - 60 = 52°

Question 3

As CD is a tangent ⇒ OC = radius ⇒ ∠OCD = 90°

The sum of interior angles of a triangle is 180°

⇒ ∠COD = 180 - 90 - 25 = 65°

As ∠COD =∠AOB then ∠AOB = 65°

As OB and OA are radii, triangle AOB is an isosceles triangle. Therefore ∠OBA = ∠OAB

Therefore x = (180 - 65) ÷ 2 = 57.5°

Question 4

As BC is the tangent to the smaller circle, OA is perpendicular to BC.

Therefore, triangle OAB is a right triangle with hypotenuse 5 cm.

Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs, and c is the hypotenuse of a right triangle):

⇒ AB² + 4² = 5²

⇒ AB = √(5² - 4²) = 3

⇒ BC = 2 x AB = 3 x 2 = 6 cm
