1. 18
2. 49.5
3. 48
Step-by-step explanation:
1. Since it is 3 dogs to 1 person we need to multiply 6 with 3, so we get 18 dogs!
2. Since 2 books equal 8.25, we just need to multiply 8.25 by 6, which we get 49.5 from!
Hope this helps and don't forget to follow!

(Pumps)/(Everything)
(10)/(9+6+10)
10/25
2/5
Answer:
Step-by-step explanation:
Since there exists a scalar
λ
λ
(namely
λ=a⋅b
λ=a⋅b
) such that
b=λa
b=λa
, the directions of the two vertices are the same (they are collinear). This implies that
|a⋅b|=|a||b|
|a⋅b|=|a||b|
.
So,
|a|=|(a⋅b)b|=|a||b||b|
|a|=|(a⋅b)b|=|a||b||b|
which implies that
|b|=1
|b|=1
