La distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno
Sonbull [250]

A) La distancia del Sol a Neptuno en notación científica es 45 x 10^8 km.  

B) Júpiter se encuentra a 930.000.000 kilómetros del Sol.  

C) La distancia del Sol a Neptuno es 30 veces mayor que la que hay a la Tierra.

Dado que la distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno está situado a 4.500.000.000 Km del Sol, para determinar:

A) Expresa en notación científica la distancia del sol a Neptuno  

B) Calcula la distancia a la que está situado Júpiter respecto al Sol  

C) Calcula cuantas veces es mayor la distancia del Sol a Neptuno que la que hay a la Tierra.

Deben realizarse los siguientes cálculos:

  • A) 4.500.000.000 = 45 x 100.000.000
  • 100.000.000 = 10^8
  • 4.500.000 = 45 x 10^8

  • B) 9.3 x 10^8 = X
  • 100.000.000 = 10^8
  • 9.3 x 100.000.000 = X
  • 930.000.000 = X

  • C) Tierra = 150.000.000
  • Neptuno = 4.500.000.000
  • 150 = 1
  • 4.500 = X
  • 4500 / 150 = X
  • 30 = X

Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right
Jet001 [13]

Answer:

Option B.

Step-by-step explanation:

It is given that ΔSRQ is a right angle triangle, ∠SRQ is right angle.

RT is altitude on side SQ, ST=9, TQ=16 and SR=x.

In ΔSRQ and ΔSTR,

m\angle S=m\angle S           (Reflexive property)

m\angle R=m\angle T           (Right angle)

By AA property of similarity,

\triangle SRQ\sim \triangle STR

Corresponding parts of similar triangles are proportional.

\dfrac{SR}{SQ}=\dfrac{ST}{SR}

Substitute the given values.

\dfrac{x}{9+16}=\dfrac{9}{x}

\dfrac{x}{25}=\dfrac{9}{x}

On cross multiplication we get

x^2=25\times 9

x^2=225

Taking square root on both sides.

x=\sqrt{225}

x=15

The value of x is 15. Therefore, the correct option is B.
