HELP!! During a local community event, a helicopter hovers 75 feet over a field and drops plastic eggs filled with candy and prizes. This situation can be modeled with the equations h= - 16t^2+75 where h is the height (in feet) of the plastic eggs as a function of time t (in seconds). The spectators must wait until the prize eggs have landed on the ground before they can run and retrieve the prizes. How long must the spectators wait after the eggs are dropped in order for a chance to retrieve a prize. Round your answer to the nearest hundredths place.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
