Answer:
XY = 16
Step-by-step explanation:
The ratio is 3 to 2 meaning that the sides of the triangle ABC and triangle AYY are in a ratio of 3 to 2. You are comparing the big triangle to the small triangle and the sides are compared the same way.
3:2 = 24:XY
3/2 = 24/XY
3 XY = 48
XY = 48/3
XY = 16
Answer:
5.5
Step-by-step explanation:
B is the midpoint of AC, D is the midpoint of CE
This means that CE = 1/2 AE
CD = 1/2 ( 11)
CD = 5.5
What numbers are you talking about love?
Answer:
The answer is 14.
Step-by-step explanation:
You solve to left to right. so, you subtract 21 by 18 first (3) then add it by 11. (14)

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)
