maw [93]

Answer:

Step-by-step explanation:

We can write an equation with the scenario given and solve for what we need, Alberto's weekly allowance.

Let his weekly allowance be "x"

Since he spend HALF of it, he spent 0.5x of it.

He has remaining also 0.5x of it

Now, whatever he has (0.5x), he gets $4 more from cleaning windows. After that he has:

0.5x + 4

This amount is equal to $8, so we can write:

0.5x + 4 = 8

0.5x = 8 - 4

0.5x = 4

x = 8

So, alberto's weekly allowance is $8

zlopas [31]

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.
