Answer:
4√15
Step-by-step explanation:
The geometric mean of x and y is √(xy).
So here we have:
√(12*20)
= √240
= √(16*15)
= √16√15
= 4√15.
Rate : 2.7 * 10 ^5 kg/hectare
m = 2.7 * 10^5 kg/hectare * 1.0 hectare = 2.7 * 10^5 kg
50°= 1/2
m ( Carbon ) = 1/2 * 2.7 * 10^5 kg = 1.35 * 10^5 kg
The mass of Carbon is 135,000 kg or 135 tons.
