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).
4) 25 < k
5) 79 * m or 79m (depending on how your teacher taught you)
6) 325/5
7) the product of 87 and x
8) the sum of 38 and s
Answer: 9
Step-by-step explanation:
180-90=90
6+4=10x
10x =90
x=9
40*4.5 +45= 225
If the service fee is not relavent to time based on my understanding.
