The elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Step-by-step explanation:
Let's assume the elevation above the sea level is on a number line, then we have to arrange the given number from lowest to highest. These are the numbers in ascending order.
–42ft, –20ft, –18ft, –8ft.
From here we see that, the elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
The number of tennis ball that will fill the room is <u>1,371 tennis balls.</u>
<em><u>Given</u></em>:
Diameter of ball (d) : 2 inch
Radius (r) = half of diameter = 1 inch
Dimension of room = 20ft by 16ft by 18ft
Number of balls that will fill the room = Volume of each ball/volume of the room
Volume of the ball = volume of a sphere = 
Where,
r = 1
let 
<em>Substitute</em>:

Volume of the room = 

Therefore:
number of tennis balls that will fill the room = 
Therefore, the number of tennis ball that will fil the room will be <u>approximately 1,371.</u>

The lengths of corresponding sides of the triangles are proportional.
AB/PQ = AC/PR
20/5 = 24/PR
4 = 24/PR
4PR = 24
PR = 6
Answer: PR = 6
