The answer is 5 . because if you count the # it will go to 28
Remark
Not many per square mile. Sounds like an ideal place to live.
Step One
Find the number of Square Miles.
Area = Height * Width
Area = 380 * 200
Area = 76,000 square miles.
Step Two
Find the Density
<u>Formula</u>
Density = Population / Square Miles
Population = 814,000 people
Square miles = 76000
Solve
Density = 814000/76000 = 10.7 people per square mile.
Remark
Isn't that incredible. It means if all the Area of South Dakota were given to the people living there, each family of 4 would get roughly 1/2 a square mile.
Answer:
2. 20
Step-by-step explanation:
2. The distance from one base of the prism to the other base of the prism, d = 10 mm
The thickness of each triangle to be used to fill the prism, t = 0.5 mm
The number of triangles needed, <em>n</em>, is therefore;
Where;
<em>d </em>represents the distance between the bases of the prism, <em>t</em>, represents the thickness of each triangle, and <em>n</em> represents the number of triangles it would take to fill up the prism
Therefore;
The number of triangles it would take to fill up the prism, n = 20
