Find the value of x.

Mathematics
1 answer:
nekit [7.7K]3 years ago
8 0

Answer:

B

Step-by-step explanation:

Since this right angled triangle has two angles of 45, so according to theorem sides opposite to equal angles are equal

Applying Pythagoras theorem

(4√2)^2=(x)^2+(x)^2

32=x^2+x^2

32=2x^2

x^2=32/2

x^2=16

Taking sq root on both sides we get

x=4

Suppose a room is 5.2 m long by 4.3m wide and 2.9 m high and has an air conditioner that exchanges air at a rate of 1200 L/min.
Readme [11.4K]

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
