Mathematics
1 answer:
Solnce55 [7]3 years ago
7 0

Step-by-step explanation:

Nine sided polygon has an angle of 360/9=40 degrees at one vertex.

So the angles opposite the radius=(180–40)/2==140/2=70degrees.

solving for Base(side): 1/2s=5.cos70= 3.42 units Ans

P=9(5+3.42)=75.78 units Ans.

For the following data at the near-ground level, which location will residents likely see dew on their lawns in the morning? Gro
Zarrin [17]

Answer: CITY B: Dew Point Temperature = 45°F, expected low Temperature = 50°F

Step-by-step explanation:

CITY C: Dew Point Temperature = 25°F, expected low Temperature = 20°F

CITY A: Dew Point Temperature = 65°F, expected low Temperature = 60°F

CITY B: Dew Point Temperature = 45°F, expected low Temperature = 50°F

city B is going to have dew on their lawn in the morning as the dew point temperature is less than the lowest temperature.

When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface. Thus dew will be formed as the conditions are suitable only for city B.
