In one cycle a heat engine absorbs 530 J from a high-temperature reservoir and expels 320 J to a low-temperature reservoir. If the efficiency of this engine is 58% of the efficiency of a Carnot engine, what is the ratio of the low temperature to the high temperature in the Carnot engine?
please show every step, thanks
