Two planes leave the airport at the same time. One plane heads directly south at 550 mph. The other plane heads directly west at 300 mph. Assuming both fly at the same elevation, how quickly is the distance between them increasing 3 hours after takeoff (rounded to the nearest mile per hour)?

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

sorry man i accidentally pressed yes my bad

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
