HELLL Bennie is calculating the density of books in a box. He knows the number of books in the box and the volume of the box. Which of the following formulas can be used to calculate the density of books in the box? Density = number of books over volume of box Density = volume of box over number of books Volume of shelf = density over number of books Number of books = density over volume of box

A. Density = number of books over volume of box

Step-by-step explanation:

Density=mass / volume

Bennie is calculating the density of a book

He knows the number of books in the box and volume of the box

Let

mass= number of books in the box

v=volume of the box

Density is given by;

Density=mass / volume

Therefore,

the density of the book=number of books in the box / volume of the box

A. Density = number of books over volume of box

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
