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

The perimeter of an equilateral triangle is 27 centimeters. Find the altitude of the triangle
Naily [24]
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find). 

A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem! 

4.5^2 + h^2 = 9^2 
h = sqrt(9^2 - 4.5^2) 
Therefore, the height is 7.79cm (2 decimal places)</span><span>
