A house with ceilings that are 2.4 meters high has five rectangular rooms with the following dimensions: 4 meters 3 5 meters; 4
andreyandreev [35.5K]

Answer:

A 21,000-Btu unit that will cool 340 cubic meters;

Step-by-step explanation:

Calculating the volume of the five rooms, we have;

Room 1:

Volume = 2.4 *4*5

             = 48 m³

Room 2:

Volume = 2.4*4*4

              = 38.4 m³

Room 3:

Volume = 2.4*6*4

             =57.6 m³

Room 4:

Volume = 2.4*6*6

             =86.4 m³

Room 5:

Volume = 2.4*6*5.5

             = 79.2 m³

Total volume of the room = 48 +38.4 + 57.6 + 86.4 + 79.2

                                           = 309.6 m³

From the total volume obtained above, the air condition that will be adequate to cool the house is  21,000-Btu unit since the obtained volume(309.6 m³) is within the range of the specify volume (340 cubic meters).

What are the coordinates of point A? (8, –6) (–6, 8) (6,-8) (-8, –6)
Jlenok [28]

The coordinates of the point A is (7, -5)

<h3>What are the coordinates of the image?</h3>

Now, we are given 4 coordinates which are;

(8, –6)

(–6, 8)

(–5, 7)

(7, –5)

Now, from the image attached, we can see that at point A, the coordinate can be traced to be (7, -5)

Thus, we conclude that the coordinates of the point A is (7, -5)

The correct question is;

What are the coordinates of point A?

(8, –6)

(–6, 8)

(–5, 7)

(7, –5)
