Answer: 292 tiles
Step-by-step explanation:
To find the number of tiles needed , we need to know the area of the hexagonal tiles and also the area of the room.
<u>Area of hexagon</u>
The area of hexagon is given as :
Area =
Where a is the length of side.
Therefore:
A =
A = X 400
A = (400 x 3 x ) / 2
A =
A = 1039.23
Also to find the area of the room , we must first convert from m to cm
6.25 m = 6.25 x 100 cm
6.25m = 625 cm
4.85m = 485cm
Therefore: Area of the room = length x breadth
Area = 625 x 485
Area = 303125
Therefore , the number of tiles needed = area of the room / area of hexagon
Number of tiles = 303125/ 1039.23
N = 291.6823032
Therefore , the number of tiles needed ≈ 292
Answer:
f(n) = (2)^(n-1)
Step-by-step explanation:
Answer:
Option A is correct option
Step-by-step explanation:
We need to find which number sentence is not true.
We will check each option.
Option A
|-20| < 20
We know that |-a|=a
20 < 20 (false)
So, this number sentence is not true.
Option B
|9| = 9
We know that |a|=a
9=9 (true)
So, this number sentence is true.
Option C
|-20|>|9|
We know that |-a|=a
20>9 (true)
So, this number sentence is true.
Option D
|9| < 20
We know that |a|=a
9<20
So, this number sentence is true.
So, Option A is correct option
-0.000 and -0.002 should be the answer
