Answer: a child ticket costs $14.50
Step-by-step explanation:
x=children ticket
x+4.50=adult ticket
3 children and 2 adult
3x+2(x+4.50)=81.50
3x+2x+9.00=81.50
5x+9.00=81.50
5x+9.00-9.00=81.50-9.00
5x=72.50
5x/5=72.50/5
x=14.50
Answer: There are 48 butterflies altogether.
Step-by-step explanation:
Since we have given that
The ratio of number of pink butterflies to the number of yellow butterflies is 3:5
So,
Let the number of pink butterflies be 3x
Let the number of yellow butterflies be 5x
As we have given that there are 18 pink butterflies,
So,
So, total number of butterflies is given by
Hence, there are 48 butterflies altogether.
Answer:
The correct answer is C
Step-by-step explanation:
Just because we have correlation in a relationship does not mean that we have causation. Therefore, we can not safely say that A or B are true.
Also, it is clearly not D as we have a strong correlation between the two and cannot safely assume that they have nothing to do with one another.
Step-by-step explanation:

Answer:
Answer B
Step-by-step explanation:
You have to use the pythagorean theorm which states that a^2+b^2=c^2
So, 7^2+x^2=9^2
49+x^2=81 subtract 49 from both sides of the equation
x^2=32
x=sqrt(32)
sqrt(32)=sqrt(16)*sqrt(2)
=4*sqrt(2)
