A human body while sleeping generates about 300 BTUs of body heat per hour. If two people are sleeping in a bedroom that is 15 f

Katarina [22]

Given:
one person can produce:
E = 300 BTUs of body heat per hour
dimensions of the bedroom is:
V = 15 ft × 12 ft × 10 ft

required: is the energy per volume if 2 persons sleeps in 7 hours
let T be the total energy produce per volume

T = (300 BTU per hour per person) ( 7 hours) ( 2 person) / ( 15 ft × 12 ft × 10 ft)

T = 2.3 BTU / ft^3

Three less than the difference of 16p and 15p is equal to the difference of 3 and 1/2

Paraphin [41]

3 less: -3

difference of 16p and 15p: 16p - 15p = p

is equal to: =

the difference of 3 and 1/2: 3 - 1/2 = 2.5

p - 3 = 2.5

Isolate the p. Note the equal sign. What you do to one side, you do to the other. Add 3 to both sides

p - 3 (+3) = 2.5 (+3)

p = 2.5 + 3

p = 5.5

5.5 is your answer for p

hope this helps
