Answer:

9

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 9 when x = - 3

9 = - 3k ( divide both sides by - 3 )

- 3 = k

y = - 3x ← equation of variation

When y = - 27 , then

- 27 = - 3x ( divide both sides by - 3 )

9 = x

33.3% do not sing in the talent show.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of kids = 3

Number of kids who sang = 2

The number of kids who do not sing.

= 3 - 2

= 1

The percentage of kids who do not sing.

= 1/3 x 100

= 33.33%

Thus,

33.3% do not sing in the talent show.

Answer:

One equation you could use is 6(7 + 5) + 3.

Answer:

[tex]((3 * 7) - 6) * 5[/tex]

Step-by-step explanation:

For this problem, we will use trial and error.

It will take a while, but we can reduce the amount of guesses we have to make.

Looking at the problem, it is obvious that we will require multiplication at some point, as adding all the numbers together is nowhere near 75.

Let's start this problem by finding the prime factors of 75:

75 = [tex]25 * 3[/tex]

75 = [tex]5 * 5 * 3[/tex]

The prime factors of 75 are: [tex]5 * 5 * 3[/tex].

Our numbers are 7, 5, 6, and 3.

We already have a 5 and a 3, so we need to use 7 and 6 to get 5, and that's impossible, so this is a pass.

Next, we'll look at another factor, [tex]25 * 3[/tex].

We already have a 3, so we can ignore that. We need to use 7, 6, and 5 to get 25.

Here are some of the results:

[tex](5 * 6) - 7 = 23[/tex] (Nope)

[tex](7 * 5) - 6 = 29[/tex] (Nope)

[tex]6 + 5 + 7 = 18[/tex] (Nope)

There's more combinations, but the numbers are either too large or too small. This is a pass too.

Now, we'll try another factor, [tex]15 * 5[/tex].

We already have a 5, so let's ignore it and use 7, 6, and 3 to get 15.

[tex]7 + 6 + 3 = 16[/tex] (Nope)

[tex](6 * 3) - 7 = 11[/tex] (Nope)

[tex](3 * 7) - 6 = 15[/tex] (Yep)

So our expression to make 15 is [tex](3 * 7) - 6[/tex]. Then we multiply the whole thing by 5. Thus our expression is:

[tex]((3 * 7) - 6) * 5[/tex]

Let's check our answer:

[tex]((3 * 7) - 6) * 5[/tex]

[tex](21 - 6) * 5[/tex]

[tex]15 * 5[/tex]

[tex]75[/tex]

The expression gives us 75, which is what we want, so our answer is correct.

Answer:

[tex]\angle BEC=55 \textdegree)[/tex]

Step-by-step explanation:

From the question we are told that:

Arc [tex]AD =65 \textdegree[/tex]

Arc [tex]BC =45 \textdegree[/tex]

Given The angle of intersecting chords theorem

Generally the equation for angle BEC is mathematically given by

 [tex]\angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)[/tex]

 [tex]\angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)[/tex]

 [tex]\angle BEC=55 \textdegree)[/tex]

Answer:

Efectivamente, la suma de la medida de los ángulos internos de cualquier figura triangular es igual a 180º. Ahora bien, la oración posee un error de redacción, pues tanto los triángulos rectos como los equiláteros o los isósceles poseen dicha característica, es decir, no es únicamente una característica de los triángulos rectos. Además, la suma de los ángulos interiores de dos triángulos rectos sería igual a 360º, no a 180º.

Answer: (X+1)(X+5)

I factored it out.

Answer:

The set of values are described below:

[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

Step-by-step explanation:

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]OJ \parallel RS[/tex] and [tex]OP \parallel RM[/tex]. By Alternate Internal Angles, we find that [tex]\angle R \cong \angle O[/tex]. In addition, the sum of internal angles in triangles equals 180°. Then, we have the following system of linear equations:

[tex]m\angle R + m\angle M + m\angle S = 180^{\circ}[/tex] (1)

[tex]m \angle O + m \angle P + m\angle J = 180^{\circ}[/tex] (2)

[tex]m\angle S = 65^{\circ}[/tex] (3)

[tex]m \angle M = m\angle P = 90^{\circ}[/tex] (4)

The solution of this system is [tex]m\angle R = 25^{\circ}[/tex], [tex]m \angle O = 25^{\circ}[/tex] and [tex]m \angle J = 65^{\circ}[/tex].

Lastly, the remaining sides are found by definition of congruence

Segment RS

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline {RS} \cong \overline {OJ}[/tex]. Hence, [tex]RS = 25\,cm[/tex]

Segment JP

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline{SM} \cong \overline {JP}[/tex]. Hence, [tex]JP = 10\,cm[/tex]

The set of values are described below:

[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

Answer:

C) ASA

Step-by-step explanation:

angles are indicated equal and they share the common diagonal between those angles, so ASA

The given two triangles are congruent due to the ASA postulate, which is the correct answer that would be an option (C).

Two triangles are said to be congruent if their corresponding sides and angles are equal.

The given triangles are given in the figure.

We can see that there are two angles that are the same and one side is the same.

According to ASA, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.

So, we conclude that the given two triangles are congruent.

Hence, the given two triangles are congruent due to the ASA postulate.

Step-by-step explanation:

Solution is in the attached picture

Answer:

Step-by-step explanation:

X^2-3x=7/4 should first be rewritten in standard form, which here would be:

x^2 - 3x - 7/4 = 0.

1.  Identify the coefficient of the x term and take half of that number:

    -3/2

2. square this result:  (-3/2)^2 = 9/4

3.  add this last result, 9/4, between the -3x term and the -7/4 term, and then      subtract it as shown:

     x^2 - 3x + 9/4 - 9/4 - 7/4 = 0

4.  Rewriting the first 3 terms as the square of a binomial, we get:

    (x - 3/2)^2  -  16/4 = 0, or    (x - 3/2)^2  =  16/4

5.  Take the square root of both sides, obtaining:

     x - 3/2 = ±√4/2 or ±√2

6.  Write out the two roots:  x = 3/2 + √2

     and                                   x = 3/2 - √2

Answer:

cosec theta = 5/4

sec theta = 5/3

Step-by-step explanation:

Given that;

cot θ = 3/4

1/tanθ = 3/4

tanθ = 4/3

since tanθ = opp/adj

opp = 4

adj = 3

hyp^2 = 4^2 + 3^2

hyp^2 = 16+9

hyp^2 = 25

hyp = √25

hyp = 5

sin theta= opp/hyp

sin theta = 4/5

cosec theta = 1/sin theta

cosec theta = 1/(4/5)

cosec theta = 5/4

Get sec theta;

sec theta = 1/costheta

sec theta = 1/(3/5)

sec theta = 5/3

HJ = 16units

Required

length of arc HK

arc HK = 50/360 * 2(3.14)(16)

arc HK = 5/36 * 100.48

arc HK = 502.4/36

arcHK = 13.96

hence the length of arcHK to nearest hundredth is 13.96
