This is a simple calculation.
Typically you convert square miles into square kilometers. But you can apply this formula to both imperial and metric systems.
Formula:
[tex]Population Density = Population/Land Area[/tex]
Here is what your equation looks like
[tex]Population density = 200/50^2[/tex]
Calculate that and you get 0.08 people per square mile.

Answer:
Over millions of years, the shape of mountains on Earth’s surface can change to low hills and then to rolling plains. These changes are most likely caused by weathering and erosion.
These changes are most likely caused by weathering and erosion
What is weathering and erosion?weathering is the breakdown or dissolution of rocks and minerals. After a rock has been broken down, the bits of rock and minerals are carried away by erosion.
Erosion is a geological process in which natural forces like as wind and water wear away and transfer earthen materials.
How does weahering and erosion cause breakdown of large hills?weathering and erosion speeds up the process of breaking down of a mountain. Erosion speeds up tectonic processes beneath the mountains by lowering the weight of the mountain range. Wind, rain, and ice increase at higher elevations and directly effect the weathering and erosion process, causing mountain tops to weather more quickly.Hence the mountain will change into a valley over many years followed by eroding into rolling plains.learn more about Weathering and erosion here:

Which endocrine gland would provide a burst of energy to a person moving out of
the way of a speeding bicycle?
(A) adrenal
(B) parathyroid
(C) pituitary
(D) thyroid
Answer:
the correct answer would be D
Explanation:
The endocrine gland that would provide a burst of energy to a person moving out of the way of a speeding bicycle is the adrenal gland, which is in Option A, as the adrenal glands are located on top of each kidney.
What is the adrenal gland?The adrenal gland is an endocrine gland located on top of each kidney. It is divided into two parts: the adrenal cortex and the adrenal medulla. The adrenal cortex produces hormones such as cortisol, aldosterone, and sex hormones, which are involved in a variety of processes in the body, including metabolism and salt and water balance. The adrenal medulla produces hormones such as adrenaline and noradrenaline, which are involved in the "fight or flight" response.
Hence, the endocrine gland that would provide a burst of energy to a person moving out of the way of a speeding bicycle is the adrenal gland, which is in Option A.

why is anaerobic respiration useful?
Answer:
It is useful during exercise. When the body doesn't get enough oxygen during exercise, it relies on anaerobic respiration for an energy supply. Instead of carbon dioxide and water, however, anaerobic respiration produces lactic acid. Also, anaerobic respiration releases less energy than aerobic respiration but it does this more quickly.
