Answer:
1.305 * 10⁻¹⁰
Explanation:
The earth disk is circular, hence the area of the earth disk is given as:
This ratio represents the fraction that would be blocked if the planet did not reflect any light, hence:
fraction of the total emitted sunlight reflected by earth = 29% of 4.5 * 10⁻¹⁰ = 0.29 * 4.5 * 10⁻¹⁰ = 1.305 * 10⁻¹⁰
the average story is 10 feet and the car is below ground so it would be negative. i assume the answer would be -20 feet

A. Used fire to do controlled burns
The result of controlled burns were highly beneficial to both the Aborigines and the environment. The burnt remains of the burns were very fertile and encouraged the growth of new vegetation that would not have been able to flourish if the older growth had not been removed. The removal of old vegetation also resulted in a low chance of wild fires. Further more new vegetation was able to attract wildlife to graze, making hunting easier.
The concept of controlled burns is still used today and was/is also practiced by First Nations in North America.
