Answer:
15%
Step-by-step explanation:
The cost of 2 adults and 2 children without the discount is
2 adults = 2 (55) = 110
2 children = 2 (45) = 90
Total cost = 110+90 = 200
The original price is 200 and the new price is 170
Percentage discount = (Original price - new price)/ original price * 100%
= (200-170)/200 * 100%
= 30/200 * 100%
= .15 * 100%
= 15%

Answer:
65.52 square feet
Step-by-step explanation:
to find area of a rhombus with the diagonals multiply them together and divide by two.
10.4 x 12.6 = 131.04
131.04/2 = 65.52 square ft
Answer:
169.04 in² (nearest hundredth)
Step-by-step explanation:
Surface area of a cone = 
r² + r
(where r = radius of the base and = slant height)
Given slant height = 10 and surface area = 188.5
Surface area = r² + r
188.5 = r² + 10r
r² + 10r - 188.5 = 0
r = 
= 4.219621117...
Volume of a cone = (1/3)r²h
(where r = radius of the base and h = height)
We need to find an expression for h in terms of using Pythagoras' Theorem a² + b² = c², where a = radius, b = height and c = slant height
r² + h² = ²
h² = ² - r²
h = √(² - r²)
Therefore, substituting found expression for h:
volume of a cone = (1/3)r²√(² - r²)
Given slant height = 10 and r = 4.219621117...
volume = 169.0431969... = 169.04 in² (nearest hundredth)
