Distance of Sun and Mercury = <span>58,000,000 km.
In Scientific notation, it would be: 5.8 </span>× 10⁷ Km

Diameter of a human hair = 0.0025 cm
In scientific notation, it would be: 2.5 × 10⁻³ cm

Before Comparison, we need to bring cms to Kms or vice-versa, so we can easily calculate then, here, we will go from cm to Km.
2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸

Now, we can compare the values, 
5.8 × 10⁷ Km > 2.5 × 10⁻⁸

[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]

Hope this helps!

Answer:

a) 58,000,000 km = 5.8 x 10^7 km

b) 0.0025 cm = 2.5 x 10^ -3 cm

c) Before a comparison is made we need to convert one of units of measurement. (cm to km OR km to cm)

Solve the problem x/27=4/9 x=
Monica [59]

Answer: x=12

Step-by-step explanation:

  • Multiply both sides by 27.
  • Use this rule: a/b*c=ac/b
  • Simplify 4×27 to 108.
  • Simplify 108/9 to 12

x=\frac{4}{9} *27\\\\x=\frac{4*27}{9} \\\\x=\frac{108}{9} \\\\x=12

Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)
