y = 3x + 8
8x + 4y = 12

Answer:900

Step-by-step explanation:

603*100/(1-33)

900

Answer: 4 and 1/2

Step-by-step explanation: Ok so 12 is a whole number so to turn it into a fraction put it over one as in 12/1.

Then just multiply 12/1 x 3/8 which equals 36/8 But we aren't done!

now we must calculate how many times 8 goes into 36 without going over 36 which is 4. 8 times 4 is 32 so we have 4 leftover. Now writing this as a fraction is 4   4/8. 4 is the whole number and that 4 represents 8 going tinto 36 4 times like we just demonstrated. since 36-32 is 4 thats how you get a 4/8 as your fraction.

Then you just simplify your fraction and 4  4/8 turns into just 4   1/2.

I really hope I explained this well and you understand it! :)

Question complète:

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%

Answer:

The answer is "[tex]153.86 \ in^2[/tex]"

Step-by-step explanation:

The circular light which fits around rather than is sufficiently large for fire a camera is indeed a ring light. The ring light provides light with very little darkness, as the bright light is very close to a lens's vertical system. It's also usually called glamour or brightness of beauty.

Let's Each light surface area has [tex]38.465\ in^2[/tex].

Therefore, the total area of four lights is [tex]38.465 \times 4= 153.86\ in^2[/tex].

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.

Answer:

-24/25

Step-by-step explanation:

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 .

Answer:

Ronique's team won at least 24 games in 75% of the season that they played.

Step-by-step explanation:

(The box-whisker plot below will show everything, but I'll explain it in detail because I want to be more helpful)

So... we have seven data points.

2014 - 15 (Year 1): 31 wins

2015 - 16 (Year 2): 24 wins

2016 - 17 (Year 3): 32 wins

2017 - 18 (Year 4): 22 wins

2018 - 19 (Year 5): 34 wins

2019 - 20 (Year 6): 28 wins

2020 - 21 (Year 7): 38 wins

We need a box & whisker plot for this.

22 will go on the left whisker, since it's the lowest of the data points. 38 will go on the right whisker, since it's the highest.

For the two quartiles, 24 is the first quartile, so from that point to the right whisker, that's 75% of the data. The third quartile will be 34. And the midline will be at 31, since it's the median of the data points.

From that explanation, we can be sure that Ronique's team won at least 24 games in 75% of the seasons that they played.

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.
