Hardy is packing his book collection into a box. Each book measures 4 inches by 6 inches by 1 inch. The box he uses to measures 24 inches by 24 inches by 8 inches. If Hardy fills the box completely, what is the greatest number of books that fit into the box? (blank) If Hardy fills the box completely with the least number of layers, there will be (blank) books in each layer. To fill the box completely, Hardy places 8 layers of books in the box. There are (blank) books in each layer.

all but the second one

step-by-step explanation:

cuz that one goes over 180

i would say c is the best answer, hope it's right!

good luck! =)

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

i think it would be 42cm
