MATHEMATICS IN DAILY LIFE.(FUN IN MATHEMATICS)

1) Anda diberi sekeping kertas 100cm panjang dan 100 cm lebar. Jika anda dikehendaki memotong keratan kertas berukuran 40cm 15 cm, berapakah jumlah keratan yang anda dapat.

PENYELESAIAN:(100 100) (40 15)

= 10 000 600

= 16.67

:- 16 KERATAN KERTAS10000 (16 600)

= 10 000 - 9 600

= 400cm

2) Berapa carakah anda boleh susun lima segiempat sama yang mana sisinya bersentuhan dan akan membentuk sebuah kotak yang tidak tertutup.

:- Kita boleh susun lima segiempat sama yang mana sisinya bersentuhan dan akan membentuk sebuah kotak yang tidak tertutup sebanyak dalam 10 cara daripada 14 cara. ANS : X, W, F, Z, T, H, L, N, Y, P : U, V, I Q

3) Amira took a collection of coloured tiles from a box. Grace took 13 tiles from Amiras collection. Kiko took half of those remaining. Amira had 11 left. How many tiles did Amira start with?

(11 2) + 13

= 22 + 13

= 35 COLOURED TILESPENYELESAIAN:

4) According to the legend of the Tower of Brahma, there are 3 vertical diamond shafts in a temple in the Indian city of Benares. At the time of creation, the god Brahma placed 64 golden disks on one shaft, in order of size with the largest at the bottom. The temple priests are to transfer all 64 fragile disks from the original shaft to another, one disk at a time. Because of their fragility, a larger disk may never be placed on a smaller one, and there is only one intermediate shaft where disks can be temporarily placed. It is said that before the priests complete their task the temple will crumble into dust and the world will vanish in a clap of thunder.How long will it take to complete the task at the rate of one step per second?

According to the legend of the Tower of Brahma, there are 3 vertical diamond shafts in a temple namely A, B, and C in the Indian city of Benares. At the time of creation, the god Brahma placed 64 golden disks on A shaft, in order of size with the largest at the bottom. The temple priests are to transfer all 64 fragile disks from the original shaft to another (A- C), one disk at a time. Because of their fragility, a larger disk may never be placed on a smaller one, and there is only one intermediate shaft ( B ) where disks can be temporarily placed.

It is said that before the priests complete their task the temple will crumble into dust and the world will vanish in a clap of thunder.

How long will it take to complete the task at the rate of one step per second?

Each golden disk takes a second to move from one shafts to another shafts.

Therefore, from A-B : 63 SecoundsA-C : 1 SecoundB-C : 63 Secounds

TOTAL : 63 s + 1s + 63s= 127 sec X 2 (time taken)= 254 sec= 254 s 60 s = 4 min 14 sec

(5) How many squares are there in the7 by 7 grid?

BILANGAN SEGIEMPATKIRAAN SEGI EMPAT TEPATJUMLAH SEGIEMPAT1 X 11 2 X 21 +453 X 31 + 4 + 9144 X 41 + 4 + 9 + 1630

Sekiranya saiz grid itu adalah n x n maka jumlah segiempat sama diperolehi dengan menambah nombor yang dikuasa dua dari 12 hingga n2 . Oleh itu, grid 7 x 7 terdiri daripada 1+4+9+16+25+36+49 = 140 segiempat sama.Anda boleh menyelesaikan masalah ini dengan mengira bilangan segiempat. Walau bagaimana pun proses pengiraan ini mengambil masa yang lama. Segiempat tersebut boleh dipecahkan kepada beberapa segiempat dan dengan mencari pola akan membantu menyelesaikan masalah dengan pantas.
