A un museo asistieron en tres días 190 personas al máximo. El segundo día asistieron el triple del primer día y el tercero un tercio del segundo día. ¿Cuántas personas asistieron cada uno de los días al museo?

The answer is 190?

Step-by-step explanation:

This is the question in English:

A museum was attended by 190 people in three days to the maximum. The second day was attended by three times the first day and the third one third of the second day. How many people attended the museum each day?

What you have to do is divide 190/3/ 1/3( 190 divided by 3 divided by 1/3.)

But if you are multiplying then dividing it will be 1710.

I hope this helps.

step-by-step explanation:

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
