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) a) 0.2 btus/ft3 b) 1.2 btus/ft3 c) 1.5 btus/ft3 d) 2.3 btus/ft3

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

1. 523.33 cubic inches

2. 113.04 cubic inches.

3. 17.41.

4. 16.49

i think this should be your answer

hope i
