Ahuman body while sleeping generates about 300 btus of body heat per hour. if two people are sleeping in a bedroom that is 15 ft × 12 ft × 10 ft, how many btus per cubic foot do they produce in 7 hours? (to the nearest tenth)

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

Step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

yes
