Let's assume
number of child tickets sold on saturday is x
number of adult tickets sold on saturday is y
On saturday, twice as many adult tickets as child tickets were sold
so, we get
child admission is $6.30 and adult admission is $9.60
a total sales of $535.50
we get
now, we can plug y=2x
now, we can solve for x
now, we can find y
so,
number of child tickets sold on saturday is 21
number of adult tickets sold on saturday is 42.........Answer
Answer:
It's D.
Step-by-step explanation:
Because, it equals to the equation written.
Answer:
<em>d) The equation of the standard parabola</em>
<em> x² = 6 y</em>
Step-by-step explanation:
The given directrix is y= -31.5
The equation of the parabola is of the form x² =4 a y
Given focus (0,1.5) , Here a= 1.5
The equation of the standard parabola
x² = 4 a y
x² = 4 (1.5)y
x² = 6 y
<u><em>Conclusion</em></u>:-
<em>The equation of the standard parabola</em>
<em> x² = 6 y</em>
