Answer:
The distance between the hands is √(3)cm ≈ 1.73cm.
Step-by-step explanation:
In a standard clock, the angle between every number is 30°, therefore the angle between 12 and 2 will be 30° x 2 = 60°.
Looking at the diagram, to find c we can make use of our cosine formula
c² = a² + b² –2abCos(C°)
a = 2, b = 1 and C° = 60°
Therefore we have:
c² = 2² + 1² –2 x 2 x 1 x cos(60°) =
c² = 4 + 1 – 4 x 0.5 =
c² = 5 – 2 =
c² = 3
c = √(3) ≈ 1.73
Therefore, the distance between the hands is √(3)cm ≈ 1.73cm.

Answer:
1. 36
2. 5390
Step-by-step explanation:
1. V=1wh/3
4 x 3 x 9 = 108
108/3 = 36
2. V=lwh/3
22 x 21 x 35 = 16170
16170/3 = 5390
Answer:
Step-by-step explanation:
6 significant digits
only the first zero is not counted.
The answer would be C:
It is a radical equation because you are solving for the variable under the radical.
To think of it another way, you must deal with the radical to find the answer
