Answer:
1. 247 mg ÷ 10 = 24.7 cg
2. 247 mg ÷ 100 = 2.47 dg
247 mg ÷ 1000 = 0.247 g
Step-by-step explanation:
1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.
2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.
3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.

Answer:
7 km
Step-by-step explanation:
Substitute:
The equation for area of a semi-circle is 
A =
76.97 =
Multiply by 2 on both sides:
2(76.97) = ( )2
153.94 = 
Divide by pi on both sides:
153.94 =
/pi /pi
49.03 ≈ 
Find the square root:
7 = r
From the equation given, the time for the black mamba snake to cover distance d, will be d/16 while that for the the rought-scaled snake would be d/1.5.
Assume that the distance covered by both snakes is 200 meters;
Then,
Time taken by the black mamba is 200/16 = 12.5 seconds, and
Time taken by the rought-scaled snake is 200/1.5 = 133.33 seconds
Clearly the black mamba is faster at 12.5 seconds compared with the rought-scaled snake.
