1point) air pressure decreases at a rate of 1.75 pa (pascals) per kilometer in the eastward direction. in addition, the air pressure is decreasing at a constant rate with respect to time everywhere. a ship sailing eastward at 8 km/hour past an island takes barometer readings and records a pressure drop of 30 pa in 2 hours. estimate the time rate of change of air pressure on the island. (pascal is a unit of air pressure 1pa=1n/m2=1kg/m∗s2) time rate of change of air pressure = pa/hr

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

15.36 per mile

but forgot to round

i am pretty sure

8.3 and the 3 is repeating

hope this .

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
