68 carnations and 32 roses.

Step-by-step explanation:

The events committee buys 100 flowers for a school dance.

The flowers are a combination of carnations and roses.

The cost of each carnation = $0.75

The cost of each rose = $2.75

The committee spends a total of = $139

Let the number of carnation be 'c' and number of roses be 'r'.

c + r = 100

r = 100 - c -------------(1)

2.75r + 0.75c = 139     [we will divide the equation by 2.75]

r + 0.272c = 50.55      [ now put the equation (1) in the place of r ]

(100-c) + 0.272c = 50.55 --------------(2)

100 + - c + 0.272c = 50.55

-0.728c + 100 = 50.55

-0.728c = -49.45

c =

c = 67.9 ≈ 68 carnations

r = 100 - c

 = 100 - 68

r = 32

The committee bought 68 carnations and 32 roses.

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
