X^2 = 300^2 + 175^2 - 2 (300)(175) cos 150
x^2 = 90000 + 30625 + 90932
x^2 = 211557
x = 459.95 miles

Step-by-step explanation:
S=cost per student ticket
a=cost per adult ticket
value=(students vlue)+(adults value)
student value=(cost per student) times number of students
adult value=(cost per adult) times number of adults
you sell 8 adult and 6 students and that is a value of 126
8a+6s=126
friend sell12 adult and 13 student and get 209
12a+13s=209
so we have
8a+6s=126 and
12a+13s=209
it might help to simplify the first equaiton by dividing by 2
4a+3s=63
we have
4a+3s=63
12a+13s=209
multiply first equaton by -3
-12a-9s=-189
add to secont equaiton
12a+13s=209
<u>-12a-9s=-189 +
</u>0a+4s=20<u> </u>
4s=20
divide 4
s=5
each student ticket costs $5.00
If one child bought a ticket, we would calculate the total cost by multiplying $4.50 by 1. If two children bought tickets, we could calculate the total cost by multiplying the total cost by 2. So, the total number of tickets will always be 4.50 * the total number of tickets.
Because the number of children who bought tickets is represented by c and the number of adults who bought tickets are represented by a, our equation should look like:
$4.50c + $4.50a = money earned
The volume of a prism = area of the base * height
substitute:
640 = A * 8
base area=80 sq ft<span />
