Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease
Answer:
The distance from sea level in mm is 0.5494 mm.
Step-by-step explanation:
Consider the provided information.
It is given that Our scale is that 100 mm on the map is equal to 6371 km in Earth.
This can be written as:
100 mm = 6371 km
Divide both the sides by 6371.
100/6371 mm = 1 km
We need to find the distance from sea level in mm, if the distance is 35 km.
Multiply both sides by 35.
100/6371 × 35 mm = 1 × 35 km
0.5494 mm = 35 km
Hence, the distance from sea level in mm is 0.5494 mm.
Answer:
EC = 15
Step-by-step explanation:
It appears that D, E, and F are the midpoints of their respective line segments (chords of the circumcircle). Hence EB = EC = 15.
Is there supposed to be a graph or another picture? I do not see anything.
