Question

If the distance from the sun to Pluto is approximately 3.5 × 10⁹ miles, what is this distance expressed in standard notation?

A) 35 million miles
B) 350 million miles
C) 3.5 billion miles
D) 35 billion miles"

Answer 1

The distance from the sun to Pluto is 3.5 × 10⁹ miles, which translates to 3.5 billion miles in standard notation, corresponding to answer C) 3.5 billion miles.

Step-by-step explanation:

If the distance from the sun to Pluto is approximately 3.5 × 10⁹ miles, this distance expressed in standard notation is 3.5 billion miles. The way to convert from scientific notation to standard notation is to move the decimal point to the right the number of times indicated by the exponent on the ten. In this case, we move the decimal point nine places to the right, thus obtaining 3,500,000,000 miles. Therefore, the correct answer is C) 3.5 billion miles.
