1. La suma de dos números es 115. El número mayor es dos veces más 22 unidades que el otro. Hallar
Lerok [7]

De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.

----------------

  • En el sistema de ecuaciones, tiene-se que los números son x e y.
  • Suma de 115, o sea, x + y = 115
  • <u>El número mayor es dos veces más 22 unidades que el otro</u>, o sea, x = 2y + 22

----------------

Primero se encuenta el número menor, <u>reemplazando la segunda ecuación en la primera:</u>

x + y = 115

2y + 22 + y = 115

3y = 93

y = \frac{93}{3}

y = 31

----------------

El número mayor es dado en <u>función de el menor</u>, o sea:

x = 2y + 22 = 2(31) + 22 = 62 + 22 = 84

Los números son 31 y 84.

Answer:

B)

4.5 cm

Step-by-step explanation:

The formula for arc length when our central angle is in degrees =

2πr(θ/360)

θ = 86°

Diameter = 6cm Radius = Diameter /2

Radius = 6cm/2 = 3cm

Hence,

Intercepted arc length = 2 × π × 3 (86/360)

= 2 × π × 3 × 0.2388888889

= 4.5029494701 cm

Approximately = 4.5 cm

Option B is the correct answer
