he got 30 % of the questions correct
each solution is negative.
there are infinite solutions.
the solutions contain rational number values.
there are no positive values as solution is less that -20.
the solution contains fractional values as well as integers.
some rational numbers in the solution are -21, -21 1/2 , -23.4 which are rational.
b. equatorial radius of saturn is approximately ten times that of earth.
equatorial radius of earth = 6 × 10³ km
equatorial radius of saturn = 6 × 10⁴ km.
so, we see that,
equatorial radius of saturn = 6 × 10⁴ = 6 × 10³⁺¹ = 6 × 10³ × 10 = (equatorial radius of earth) × 10.
i.e. equatorial radius of saturn = equatorial radius of earth × 10
hence, we get that,
equatorial radius of saturn is approximately ten times that of earth.
