Answer:

1.5BTU/ft³( to nearest tenth)

Step-by-step explanation:

A human body generates 650BTus of heat per hour.

To get the amount of heat generated by a room with the dimension 10 ft × 12 ft × 9 ft

First we will find the volume of the room in cubic ft

Volume = length ×breadth × width

Volume = 10×12×9

Volume = 840ft³

This means 840ft³ produces 650Btu of heat by one body.

For 1ft³, amount of BTUs generated by the three person in an hour will be (640/840)BTU i.e 0.762BTU

Amount of heat in BTU/cubic feet generated in 2 hours will be

2 × 0.762BTU/ft³

= 1.524BTU/ft³

= 1.5BTU/ft³( to nearest tenth)

A vender bought an earphone for $1378 and she sold it in order to make a profit of 17. 5% calculate the profit made in cash and
Inessa [10]

The profit he made from selling his hearing aids at a profit of 17% is $234.26.

<h3>How to calculate the profit obtained?</h3>

To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.

  • $1,378 ÷ 100 = $13.78
  • $13.78 × 17 = $234.26

Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.

$1,378 + $234.26 = $1,612.26
