En una escuela hay 135 mujeres y la razón entre hombres y mujeres es de 7 a 9. ¿Cuántos estudiantes hay en la escuela? *

Answer:

There are 531.5625 students which is 531 students in the school

Step-by-step explanation:

We add the ratio numbers ( 7 + 9 = 16)

We then divide that number by 135 ( 135 / 16 = 8.4375)

After we multiply by each ratio number, ( 7 and 9).

And we end up with 531.5625, also 531 students.

Hay 531.5625 estudiantes, que son 531 estudiantes en la escuela.

Explicación paso a paso:

Sumamos los números de razón (7 + 9 = 16)

Luego dividimos ese número por 135 (135/16 = 8.4375)

Después, multiplicamos por cada número de razón (7 y 9).

Y terminamos con 531.5625, también 531 estudiantes.

Determine two pairs of polar coordinates for the point (4, -4) with 0° ≤ θ < 360°.

umka2103 [35]

A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.

The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,

r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)

Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2

The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°

Hence, the polar coordinate is <em>(4√2, 315°)</em>
