Explain why 2/3 ×12 can be written as 2 × 12 ÷3

nalin [4]

Answer:

violates the rules or bedmas

Step-by-step explanation:

When doing questions like these, bedmas comes into play. althought multiplication and division are the same in terms of priority, you should do the one that comes first when reading the equation/formula left to right.

this would mean you would do 2 ÷ 3 and the answer would be multiplied by 12.

An oval track is made by erecting semicircles on each end of a 46 m by 92 m rectangle. Find the length of the track and

Alexxandr [17]

Answer:

$Length\,\, of\,\, the\,\, track=420.44\,m\\\\Area\,\,covered \,\,by\,\, the\,\, track=5893.06\,m^2$

Step-by-step explanation:

Length of the Track:

Perimeter of the rectangle + Circumference of the two semicircle

Perimeter of the rectangle= $2(Length+Width)$

$Length=92\,m\\Width=46\,m$

Perimeter of the rectangle:

$=2(92+46)\\\\=2(138)\\\\=276\,m$

Circumference of Two Semicircle with same radius:

$r=\dfrac{46}{2} =23\,m$

$Circumference=2\times \pi \times r\\\\$

$=2\times 3.14\times 23\\\\=6.28 \times 23\\\\=144.44\,m$

Total Length of the track is :

$=276+144.44\\\\=420.44\,m$

Area Covered by the track is :

Area of the two semicircle + Area of the rectangle

$=(\pi \times r^2) + (Length\times Width)\\\\=(3.14\times (23\times 23 ))+(92\times 46)\\\\=1661.06 +4232\\\\=5893.06\,m^2$
