Idon't get it and also tell me what is the answer for the riddle and answers for every box

They both have a rattle

(Letter by letter for each box)

Step-by-step explanation:

All you are doing is turning the fractions into percentages or decimals, and the percentages into fractions or decimals. You also convert the shaded shapes into fractions, decimals, or percents.

For example, 1/2= 50%, 20%=.2, and .5=50%.

I hope I helped!! If you need me to explain more just let me know!

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
