What is a positive solution of x squared -36=5x
miv72 [106K]
Answer : 9


Explanation:

{x}^{2}  - 36 = 5x


Subtracting -5x from both sides,

{x}^{2}  - 5x - 36 = 0

Soving this quadratic equation by midterm split method,

{x}^{2}  - 9x + 4x - 36 = 0 \\  \\ x(x  - 9) + 4(x - 9) = 0 \\ (x - 9)(x + 4) = 0


So the roots here will be, +9 and -4.

Since the question is about only the positive value.
Your answer will be 9.

statuscvo [17]

Answer:

150 hombres juegan baloncesto.

Step-by-step explanation:

En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.

Paso 1

Encontramos el número de estudiantes que son mujeres

= 1/3 × 315

= 105 mujeres.

Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:

= 315 - 105 mujeres

= 210 hombres

Paso 2

2/7 de los hombres juegan fútbol y el resto baloncesto.

Esto significa que 2/7 de 210 hombres juegan al fútbol

= 2/7 × 210 hombres

= 60 hombres

Por tanto, 60 hombres juegan al fútbol.

Paso 3

También se nos dice que el resto juega al baloncesto.

El número de hombres que juegan baloncesto se calcula como:

210 - 60

= 150 hombres.

Por tanto, 150 hombres juegan baloncesto.

The exclamation point (!) on a billboard consists of a circle sector and circle. The radius of the sector is 9 ft, and the radiu
harina [27]

Answer:

  24.0 square feet

Step-by-step explanation:

The area of the sector is given by ...

  A = (1/2)r²θ . . . . . where θ is the angle in radians

The area of the circle is the same, with θ=2π, so is ...

  A = πr²

__

In this problem, the area of the sector is ...

  A = (1/2)(9 ft)²(24π/180) = 27π/5 ft² ≈ 16.9646 ft²

The area of the circle is ...

  A = π(1.5 ft)² = 9π/4 ft² ≈ 7.0686 ft²

Then the total area of the exclamation point is ...

  16.9646 +7.0686 ≈ 24.0 . . . ft²

The area is about 24.0 square feet.
