Answer:
54 minutes
Step-by-step explanation:
From the question, we are given;
- A room with dimensions 5.2 m by 4.3 m by 2.9 m
- The exchange air rate is 1200 L/min
We are required to determine the time taken to exchange the air in the room;
First we are going to determine the volume of the room;
Volume of the room = length × width × height
= 5.2 m × 4.3 m × 2.9 m
= 64.844 m³
Then we should know, that 1 m³ = 1000 L
Therefore, we can convert the volume of the room into L
= 64.844 m³ × 1000 L
= 64,844 L
But, the rate is 1200 L/min
Thus, time = Volume ÷ rate
= 64,844 L ÷ 1200 L/min
= 54.0367 minutes
= 54 minutes
Therefore, it would take approximately 54 minutes
Answer:
D, $75.00 because 35 plus 15 plus 20 is 75.
Answer:

Step-by-step explanation:
We have the function 
In this case we want to find the value of f0)
To find f(0) you must replace the x in the function with the number 0 and solve as shown below



Therefore

Answer:
y=-99x
Step-by-step explanation:
it's imposible to answer y in terms of a number, but it is possible to do it in terms of x.
x-y=100x
x=100x+y
-99x=y
y=-99x
