At a given time, Saturn was 9.1 x 10 to the 8th miles from the sun and the earth was 9.3 x 10 to the 7th miles from the sun. by what distance is one planet closer to the sun than the other planets?
8.17 x 10^8
To find the distance by which one planet is closer to the sun than the other, we need to subtract the distance of one planet from the distance of the other planet.
Given:
Distance from the Sun to Saturn = 9.1 × 10^8 miles
Distance from the Sun to Earth = 9.3 × 10^7 miles
To find the difference, we subtract the distance of Earth from the distance of Saturn:
9.1 × 10^8 miles - 9.3 × 10^7 miles
To subtract these values, we need to ensure they are in the same unit (both in miles). We can convert the second value to the same unit and then subtract.
The distance of Earth from the Sun can be written as 9.3 × 10^7 miles.
To convert it to miles, we keep the number part (9.3) the same and multiply it by 10 raised to the power of 7 (10^7).
Thus, the distance of Earth from the Sun is 9.3 × 10^7 miles.
Now we can subtract the distances:
(9.1 × 10^8 miles) - (9.3 × 10^7 miles)
To subtract these values, we need to ensure the exponents of 10 are the same. In this case, both exponents are already 8, so we can subtract the numbers in front:
9.1 - 9.3 = -0.2
The difference in distance is -0.2. Since it is negative, it means that Earth is closer to the Sun than Saturn by 0.2 units, but in the same magnitude (miles in this case).
Therefore, Earth is closer to the Sun than Saturn by 0.2 units (miles).
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
9.1*10^8 - 9.3*10^7 = 91*10^7 - 9.3*10^7 = (91-9.3)*10^7 = ?
