Step-by-step explanation:
Facts
MARY
8% commision on everything she sells
She sells a car for $14,500
The first question about Mary asks how much commision she makes. To find that, lets find 8% of 14,500
8% of 14,500= 0.08x14,500= 1160
Therefore, Mary makes $1,160 in commision.
STEVEN
Facts
He makes 15% in commision for the supplies he sells
He sells $950 in supplies
Money made =?
15% of 950=0.15x950=$142.50
Answer:
B is correct i think
Step-by-step explanation:
Angle between
is
° .
<u>Step-by-step explanation:</u>
We have , two vectors u = <-5, -4>, v = <-4, -3> or ,
We need to find angle between these two vectors . Let's find out:
We know that dot product of two vectors is defined as :
, where x is angle between u & v !
⇒ 
⇒ 
Now , 
⇒ 
⇒
{
}
⇒ 
Now , Modulus of any vector
is
So ,

Putting all these values in equation
we get:
⇒ 
⇒ 
⇒
{
}
⇒
°
Therefore , Angle between
is
° .
