The student council has spent much time planning the Dance of the Year. In planning for the event, it is found that the cost to have the dance would be: $1,000 for the band
$200 for the room rental
$2 per person for refreshments
$0.50 per person for advertising
The student council expects that 200 to 400 students will attend the dance.
-Assuming that the number of tickets will be between 200 and 400, determine an appropriate price that should be charged for each ticket to be certain that a profit is made.​

no one knows lol

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363

i think its a.

hope this
