Answer:
Geography.
Step-by-step explanation:
Geographers use many tools in their work. Maps, globes, photos, satellite images, and models are all tools that geographers might use. Geographers who study ancient Egypt might want to know how the people used the Nile River. For example, the Nile is known to flood. Geographers might study how people dealt with flooding. They might also want to know if or how they used floods to help them.

Answer:
40 quarts
Step-by-step explanation:
For this question, you set up a proportion. You know that Kelsey jarred 12 quarts of jam after 3 days so you set 12 quarts/3days equal to x quarts/10days.
12 quarts/3 days=x quarts/10 days
Then, you can cross multiply. You get 3x=120.
Then, divide 3 by both sides to get x by itself.
120/3=40
Your answer is 40 quarts.
Hope that helps!
Answer:
11.8cm²
Step-by-step explanation:
The area of the regular pentagon is expressed as;
A = pa/2
p is the perimeter of the pentagon
a is the apothem
Since p = 5s
s is the side length, hence;
A = 5sa/2
Get the side length s;
central angle = 360/5
central angle = 72degrees
angle in the right angle triangle =72/2 = 36degrees
Using SOH CAH TOA
sin 36 = x/2
x = 2sin36
x = 1.1755
s = 2x
s = 2.35cm
Get the area
A = 5(2.35)(2)/2
A = 5(2.35)
A = 11.8cm²
Hence the area of the regular pentagon is 11.8cm²
