Ten strands of healthy bacteria are placed on a petri dish and are allowed to freelymultiply. Nutrients are supplied to the bacteria continuously. If at 4 hours there are 2000strands of healthy bacteria on the petri dish, how much longer will it take for the petri dishto contain 100,000 strands of healthy bacteria? (Round up to the nearest hundredths).O 4.96 hoursO 2.96 hoursO 0.96 hoursO 6.96 hours A steel bar is heated in a furnace until it reaches 2000°F. The blacksmith observes that itcools to 1500°F in 15 minutes. It needs to be hammered into shape before it gets within500°F of the room temperature (100°F) before it gets too cold to be shaped properly.After pulling out the steel bar from the furnace, how long does the blacksmith have beforeit needs to be reheated? Assume that Newton's law of cooling is applicable.O 76.5 minO 101.8 minO 56.6 minO 65.6 min
