Mr. eger is planning a party for his homeroom class. there are 30 students in his class. he wants each student to have a serving of 8 oz. of juice. each jug of juice contains 40 oz. a) identify the unit rate (the number of servings per jug) b) using this rate, set up and solve the proportion to determine how many jugs of juice he will need for the party.

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
