Sixteen stuStudents in a drama club want to attend a play the ticket price is $35 for each student and the transportation and meals for everyone will cost 960 to pay for the trip is on sweatshirt to Sell profile of 19Dollars per sweatshirt if each student so the same number of sweatshirts how many sweatshirts must each student sell so that their will be enough money to pay for the entire cost of the trip

2 sweatshirts per student

Step-by-step explanation:

I'm not sure whether or not I understood this problem correctly, but I tried my best. Try to make your questions more clear in the future.

($35 per ticket * 16 students) + ($19 per sweatshirt *  X sweatshirts sold) = $960

$560 from the sweatshirt + 19X = 960

19X = 960 - 560 = $400

X = 21 sweatshirt sold overall

Number of sweatshirt sold per student = 21/19 = 1.105 ---> 2 per student

the answer to this question is 3/19

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
