Answer:

164.32 earth year

Step-by-step explanation:

distance of Neptune, Rn = 4.5 x 10^9 km

distance of earth, Re = 1.5 x 10^8 km

time period of earth, Te = 1 year

let the time period of Neptune is Tn.

According to the Kepler's third law

T² ∝ R³

$\left ( \frac{T_{n}}{T_{e}} \right )^{2}=\left ( \frac{R_{n}}{R_{e}} \right )^{3}$

$\left ( \frac{T_{n}}{1} \right )^{2}=\left ( \frac{4.5\times10^{9}}}{1.5\times10^{8}}} \right )^{3}$

Tn = 164.32 earth years

Thus, the neptune year is equal to 164.32 earth year.

John finds a toy train set John finds a toy train set on sale for 20% off at a toy store. The original price was $35. John

Helen [10]

Well here's your answer straight he must pay 29.82$ and here's my work,

20% of 35 is 7 and since its 20% off we must subtract 35-7=28
Next it said there's a 6.5 tax so that means we are adding on to 28$
6.5 of 28 is 1.82 so we add 28+1.82 which equals your answer 29.82
