Answer:
26 child tickets
Step-by-step explanation:
4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.
6.10c + 9.90(4c) = 1188.20
6.10c +39.6c = 1188.20
45.7c = 1188.20
c = 26
Answer:

Step-by-step explanation:
The directrix y=-6 is parallel to the x axes, so parabola has equation of the form

where
is the vertex of parabola and p is parabola's parameter.
By the definition,
is the distance from the vertex to the directrix, so

Hence, the equation of parabola is

See attached diagram for the graph of parabola and its directrix.
In vertex form this equation is

Answer: about 34.6
Step-by-step explanation: 11 is the radius, but you need the diameter which is 22. multiply 22 by pi and divide that number by 2 since it is half a circle.
