Answer:
a) Here x represent number of ride tickets
z represent admission fees. = $20
y represent total cost.
Step-by-step explanation:
a) Here x represent number of ride tickets
z represent admission fees.
y represent total cost.
b) Given that,
$0.75 per ticket for the rides.
Number of tickets (x) = 18
Total spent (y) = $33.50
Total cost = (number of tickets)*(price per ticket) + admission fees
y =0.75x + a
We can calculate the cost for anyone who only pays for festival admission and rides.
c)
Put y = 33.50
x = 18
33.50 = 0.75*18 + a
33.50 = 13.5 + a
Solve for a,
Subtract 13.50 both the side
33.50 - 13.50 = 13.50-13.50 + a
20 = a
So, admission cost (a) = $20
Answer:
This means the height of the triangle is twice the height of the rectangle.
Step-by-step explanation:
Area of a rectangle is given as product of length and width, A=l*w
Area of triangle is given as the product of the base length by half the height,
A= 1/2 *b*h
If the areas are the same then it means;
l*w = 1/2 *l*h where l is the base length
l*w = l*h/2 ------but the base measurement is the same thus
w= h/2
2 w = h
This means the height of the triangle is twice the height of the rectangle.
Because the distance to both chords are the same (5.70) and both chords are 90 degrees from the 5.70 line, both chords are identical.
Chord AB = 5, so chord CD is also 5.

The total cost of 1000 CD's given that each costs $6.45 is equal to $6450. The revenue is the product of the number of CD's sold, n, and the selling price of each is $12.95. The equation for the profit or loss of "CD Universe" is, P = 12.95n - 6450
