At an amusement park, 3,750 out of 5,000 tickets sold were discount tickets. what percentage of the tickets were discount tickets?

The percentage of discounted tickets with respect to total tickets is 75 %

Step-by-step explanation:

Given as :

The total tickets of amusement park = 5,000

The total discounted tickets of amusement park = 3,750

Let The percentage of discounted tickets with respect to total tickets = D %

Now, According to question

The discounted percentage = × 100

or, D = × 100

or, D = 0.75 × 100

or D = × 100

∴ D = 75 %

So, percentage discounted tickets = D = 75 %

Hence The percentage of discounted tickets with respect to total tickets is 75 % . Answer

1/5x+9 2/5y+7

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
