Saya yakin jawabannya adalah -26 karena ketika Anda melakukan perkalian terlebih dahulu, kemudian lakukan pecahan 33 1/2 dan setelah itu Anda akan menambahkan 2 dan pengurangan 5,5 yang semuanya akan sama dengan -26. semoga saya benar dan ini membantu. (:
Answer:
9,103.69
Step-by-step explanation:
y = A(d)^x
y = 12000(1-0.129)^2
Decay y = 12000(0.871)^2
solve for y = $ 9,103.69
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
