<u>Answer:</u>
<u>Answer:Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values. For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √(3×1) = √3 = 1.732.</u>
Answer:
1) Volume of water displaced = 5.16 L
2) Copper sinks in water.
Explanation:
1) Density of copper = 8.92
Mass of copper = 46 kg = 46000 g
We know that, Density = Mass / volume
So, Volume = Mass/ density
Volume of copper = 46000/8.92 = 5156.95
Since the density of copper 8.92 is greater than density of water 1, the copper immerses in water. Since it immerses it will displace a volume of water which is equal to the volume of copper.
So volume of water displaced = volume of copper = 5156.95 =5.16 L of water
2) Since the density of copper 8.92 is greater than density of water 1, the copper immerses in water. So copper sink in water.
Answer:
-3/12
Step-by-step explanation:
The answer for the question is -7x+4
Since angle of depression = 72°54 minutes.
60 minutes = 1°
54 minutes = 54/60 = 0.9°
Therefore 72°54 minutes = 72° + 0.9° = 72.9°
Since angle of depression = 72.9°, the reverse angle of elevation = 72.9°
(Picture representation of this using right angled triangle is needed)
tan 72.9° = Opposite height / Horizontal distance
tan 72.9° = 1191 / x
x = 1191 / tan 72.9 Use a calculator.
x ≈1191 / 3.2506
x ≈ 366.39
Horizontal distance ≈ 366.39 feet.
Hope this helped.
