Answer: Area = 17.5 unit²
Concept:
Here, we need to know how to calculate the area of a triangle.
Area (triangle) = b · h · (1/2)
b = base
h = height
Solve:
<u>Given information (By counting grids on the graph)</u>
b (AB) = 7
h (BC) = 5
<u>Given expression</u>
Area = b · h · (1/2)
<u>Substitute values into the expression</u>
Area = (7) · (5) · (1/2)
<u>Simplify by multiplication</u>
Area = (35) · (1/2)
Area =

Answer:
793.25 mi/hr
Step-by-step explanation:
Given that:
The radius of the earth is = 3030 miles
The angular velocity =
If a jet flies due west with the same angular velocity relative to the ground at the equinox;
We are to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.
NOW;
Distance s is expressed by the relation
s = rθ
s = 793.25
The speed which depicts how fast in miles per hour the jet would have traveled is :
v = 793.25 mi/hr
Hence, the jet would have traveled 793.25 mi/hr due west at the 40th parallel for this to happen.
