Keith ran a total of 6 miles over the course of 3 track practices. How many track practices would it take for Keith to run 16 miles? Assume the relationship is directly proportional.

8

Step-by-step explanation:

6/3=2

one track practice is equal to 2 miles

and 2x8=16 so for 8 track practices he has ran 16 miles

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

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
