toby is arranging books on a shelf. the shelf is 47 cm long to the nearest centimetre. each book is 2.5 cm wide to the nearest milimetre. show that toby can definalty fit 18 books on the shelf

➠54.milimetre.

Step-by-step explanation:

➠each book is 2•5 Milimetre .

➠18 books=??

➠1 book = 2•5

➠18 books=18*2•5

➠54. milimetre.

Yes, he can fit 18 books on the shelf.

Step-by-step explanation:

They will fit if maximum width of 18 books is less than minimum length of the shelf.

The minimum length of the shelf is 46.5 cm ( as its measured to nearest cm).

The maximum width of a book < 2.55   ( its measured to nearest 0.1 cm).

So multiplying width of books by 18 we get:

2.55*18 = 45.9 which is less than 46 so the answer is YES.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
