Question
Which method is most effective for disposing of hazardous
waste?Solution
Incineration is the preferred method for hazardous waste disposal because it reduces waste volume while generating energy. The process involves burning waste at high temperatures to create ash, heat, and combustion gases. The heat produced can be converted into electricity. Incineration effectively destroys microorganisms and can treat large volumes of infectious waste, making it particularly suitable for hospital waste. However, it does have drawbacks, including the potential release of pollutants and greenhouse gases.
(180 Γ· 22 ) Γ· (60% of 30) = (? Γ· 2)
1299.999 Γ· 325.018 Γ 24.996 = ?
22% of 560 + 34% of 2160 Γ 5/12 =? + 16% of 920
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
What value will come in place of (?) question mark in the given expression.
{ (18)Β² β (12)Β² } Γ· 6 = ?
Simplify:
(2β50 + 3β18 - β8) / β2
Simplify:

1672 ÷ 19 = ?% of 220
