Shah's training heart rate = 127.8 beats/min

shah's daughters training heart rate = 143.4 beats/min

Step-by-step explanation:

we know that both their resting heart rate is 60 (R=60)

so to find their respective maximum heart rate, put 60 into the M equation;

ie, for shar M = (220-A) Age = 47 given

so for shar m = 220-47 = 173

for her daughter m = 220-21 =199

Now we have this we can find the training heart rate which is by the equation, T = R + 0.6(M - R) we know both r and m.

for shar T = 60 + 0.6(173 - 60) = 60 + 0.6x113 = 60+67.8 = 127.8 beats/min

for her daugter T = 60 + 0.6(199-60) = 60 + 0.6x139 = 60 + 83.4 = 143.4 beats/min

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
