] | C | When a number is divided by another number, we can represent it as : Dividend = Quotient * Divisor + Remainder
So, Dividend/Divisor = Quotient + Remainder/Divisor
Given that N/J = 204.04
Here 204 is the quotient.
Given that Remainder = 16
So, 204.04= 204 + 16/J
So, J = 400

What type of winds move the same way as mountain and valley breezes? | [
"pyroclastic winds",

] | D | Katabatic winds move the same way as mountain and valley breezes. However, they are much stronger. Katabatic winds form over a high plateau that is surrounded by mountains. In winter, the plateau grows cold. Air sinks through the gaps in the mountains. Over Antarctica and Greenland, these winds are frigid. | SCiQ_train |
