Answer:

El precio del saco del azúcar es de 72.

Step-by-step explanation:

Sean x, y los precios del saco de arroz y el saco de azúcar, respectivamente. A continuación, traducimos cada oración relevante en ecuaciones matemáticas:

(i) <em>El precio del saco de arroz es a 2 como el precio del saco de azúcar es a 3</em>:

Aquí se menciona una igualdad entre expresiones racionales, es decir:

\frac{x}{2} = \frac{y}{3}

3\cdot x -2\cdot y = 0 (1)

(ii) <em>El producto de ambos precios es numéricamente 3456</em>:

x\cdot y = 3456 (2)

Ahora resolvemos el sistema de ecuaciones, despejamos x en (1):

x = \frac{2}{3}\cdot y

Y la aplicamos en (2):

\frac{2}{3}\cdot y^{2} = 3456

y^{2} = 5184

y = 72

El precio del saco del azúcar es de 72.

point K is between points M and Q. If line segment MK = 7 inches and line segment MQ = 15 inches, whst is the measurement of KQ?
BigorU [14]

The total length of a line segment is the sum of the lengths of its parts.

MQ = MK + KQ . . . . . . express the relationship between the segments

15 in = 7 in + KQ . . . . . fill in the given information

(15 - 7) in = KQ . . . . . . .subtract 7 in

KQ = 8 in . . . . . . . . . . . simplify

Look at the figure and answer
andreyandreev [35.5K]

Answer:

\cos x=\dfrac{8}{f}

Step-by-step explanation:

Given that,

\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}

We need to find the value of cos x.

We know that,

\tan\theta=\dfrac{\sin\theta}{\cos\theta}

Using the above relation,

\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}

So, the value of cos x is equal to \dfrac{8}{f}.
