Answer:
<h2>90°</h2>
Step-by-step explanation:
First you must calculate the module or the magnitude of both vectors
The module of u is:

The module of v is:

Now we calculate the scalar product between both vectors

Finally we know that the scalar product of two vectors is equal to:

Where
is the angle between the vectors u and v. Now we solve the equation for 

the answer is 90°
Whenever the scalar product of two vectors is equals to zero it means that the angle between them is 90 °
No it does not stay the same
Original ratio is 6:5 which means it will only stay the same if the amount of movies to band is taken at multiples of this ratio. per sample if 24 movies are sold then
24/6=4 so you will have to multiply or sell 5*4=20 of the band ones to be able to keep same ratio.
Answer:
yes u right
Step-by-step explanation:
Answer:
I think the answer is 7.75/100
Right triangles have a 90 degree corner.
