Let us say,
Price of adult ticket=x
Price of child ticket =y
On the first day ticket sales the school sold 4 adult tickets and 12 child tickets for total of $80
4x+12y=80.............(1)
took $41 on the second day by selling 1 adult ticket and 10 child tickets
1x+10y=41.............(2)
x=41-10y..............(3)
plugging the value of x from equation (3) in equation (1) we get,
4(41-10y)+12y=80
164-40y+12y=80
84=28y
y=3
plugging this value of y in equation (2) we get,
1x+10(3)=41
x=11
Price of adult ticket= 11 dollars
Price of child ticket = 3 dollars

the answer is 1/4
Hi!
Answer:
A) 331.24
Step-by-step explanation:
To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.
I hope this helps! :)
<h3>Answer: C) none of the equations are identities</h3>
If you plugged theta = 0 into the first equation, then you would have
sin(45) + cos(45) = sin(0) + cos(0)
sqrt(2) = 1
which is a false equation. We don't have an identity here.
The same story happens with the second equation. Plug in theta = 0 and it becomes
cos(60) - sin(60) = cos^2(0) + tan(0)
1/2 - sqrt(3)/2 = 1 + 0
-0.37 = 1
which is false.
