Answer:

BC = 3

Step-by-step explanation:

The length of the side BC is 3 units.

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

The right triangle is shown in the figure.

Let the distance BC be x and

The side AB be y.

According to trigonometric ratios,

[tex]tan \theta=\frac{opposite}{adjacent}[/tex]

Consider Δ ABD,

⇒ [tex]tan (20) = \frac{y}{x+15}[/tex]

⇒ [tex]0.3639=\frac{y}{x+15}[/tex]

⇒ [tex]y=0.3639(x+15)[/tex] -------- (1)

Now consider Δ ABC,

⇒ [tex]tan(65)=\frac{y}{x}[/tex]

⇒ [tex]2.144=\frac{y}{x}[/tex]

⇒ [tex]y=2.144x[/tex] --------- (2)

From equation 1 and 2,

⇒ [tex]2.144x=0.3639(x+15)[/tex]

⇒ [tex]2.144x=0.3639x+5.4585[/tex]

⇒ [tex]1.7801x=5.4585[/tex]

⇒ [tex]x=\frac{5.4585}{1.7801}[/tex]

⇒ [tex]x=3.06[/tex] ≈ [tex]3[/tex]

Hence we can conclude that the length of the side BC is 3 units.

150 garçons et 250 filles sont inscrits au conservatoire. 20% des garçons et 30% des filles sont pianistes. Calculer le pourcentage de pianistes au conservatoire

Répondre:

26,25%

Explication étape par étape:

Nombre de garçons = 150

Nombre de filles = 250

Pianiste masculin = 20% des garçons

Pianiste masculin = 0,2 * 150 = 30 garçons

Pianiste féminine: = 30% des filles

Pianiste féminine = 0,3 * 250 = 75 filles

Nombre total de pianistes:

(30 + 75) = 105 pianiste

Population du conservatoire = (150 + 250) = 400

Pourcentage de pianiste:

105/400 * 100%

0,2625 * 100%

26,25%

The second number in an ordered pair is the y-coordinate and corresponds to a number on the y-axis.

Step-by-step explanation:

hope this helps you! :)

The second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.

a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.

An ordered pair contains the coordinates of one point in the coordinate system.

A point is named by its ordered pair of the form of (x, y).

In an order pair the first number represents the x coordinate and the second number represents the y coordinate.

To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

Hence, the second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.

Step-by-step explanation:

Answer:

Area = (4 × 6.5) ÷ 2

→ Simplify

Area = 13 yd²

Answer (assuming that the equation can be written in point-slope form):

[tex]y-8 = -5(x+\frac{1}{2} )[/tex]

Step-by-step explanation:

Use the point-slope formula, [tex]y-y_1 = m (x-x_1)[/tex] , to write the equation of the line in point-slope form. Substitute values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.

Since [tex]m[/tex] represents the slope, substitute -5 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, substitute the x and y values of (-0.5, 8) into the formula as well. Remember that we can convert -0.5 to a fraction: [tex]-\frac{1}{2}[/tex]. So, substitute [tex]-\frac{1}{2}[/tex] for [tex]x_1[/tex] and 8 for [tex]y_1[/tex]. This gives the following answer and equation:

[tex]y-8 = -5(x+\frac{1}{2} )[/tex]

Answer:

D. The company's chocolate bars weigh 3.2 ounces on average.

Step-by-step explanation:

We are given that  a company claims that its chocolate bars weigh 3.2 ounces on average.

The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.

Thus Option D is correct.

D. The company's chocolate bars weigh 3.2 ounces on average.

Answer:

D.(4x+1)

Step-by-step explanation:

The area of the rectangular pool is given by

Area = length * breadth

Area = (12x×x)-17x-5

A= 12x²- 17x- 5

Factorising the quadratic equation by mid term break rule.

A= 12x²- 20x + 3x- 5    

( when we multiply 12 and -5 we get -60 . We need two numbers which when added give -17 and when multiplied give -60. The two numbers would be -20 and +3. The minus has to be with the bigger number as we need - 17.)

A = 4x( 3x- 5) + 1( 3x-5)

(taking commons will evaluate it further.)

A= (3x-5) (4x+1)

so the length could either be 3x-5 or 4x+1

From the given options we have

4x+1 as the length because the rest do not match the factors obtained.

Answer:one yard costs $15 (x=15)

Step-by-step explanation:

16x=240

240/16=15

X=15 (one yard costs $15)

The price for  one square yard of carpet is $15.

Given that,

Based on the above information, the calculation is as follows:

Step-by-step explanation:

Start at the orgin.

The y intercept in the equation is -1 so I would shift 1 unit down to the orgin at (0,-1)

Then at the point, since the slope is -4. I would go down -4 units then go over 1 unit to the right.. So the next point would be (1,-5) then so on and so on.

Because it is in quadrant 3, cosine is negative. Hypotenuse=25, Adj=-24, Opp, -7. Cos=Adj/Hyp. -24/25

It is Given that tan⁡ θ = 7/24, and ⁡θ terminates in Quadrant III, Thus the value of cos⁡ θ is -24/25.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given tan⁡ θ = 7/24, and ⁡θ terminates in Quadrant III,

we want to determine the value of cos⁡ θ.

Because it is in quadrant 3, cosine is negative.

Hypotenuse = 25, Adjcent = -24, Opposite = -7.

Cos θ = Adjcent /Hypotenuse .
