Answer:
0.315 hectares
Explanation:
To get the answer, we use the area of a trapezium formula, which is ½ (a+b) h, where a and b are the parallel sides and h is the height.
So ½(90m+50m) 45m
½ × 140 × 45
70 × 45 = 3150m²
10000m²= 1hectare
3150m² = x
3150 ÷ 10000 = 0.315 hectares.
The similarities are: 1. Both are compounds, different types of atoms.
2. Both contain H and O 3. Both are formed form covalent bonds or non metals.
3. Both are clear liquids at room temperature.
Hope this helps!
Keplers 3rd law tells us that the square of the orbital period of a planet is proportional to the cube of the semi-major axis if the planet.
p^2 = a^3
So if the orbital period is 29.46 years, then:
(29.46)^2 = a^3
867.8916 = a^3
9.54 au = a
So the average distance between Saturn and the Sun is 9.54 au
au = atronomical units.
idk if i did this right, its been a while
