Answer:
x = 25
y = 65
Step-by-step explanation:
(I did it on Math Nation)
180 = 130 + 2x
50 = 2x
x = 25
180 = 50 + 2y
130 = 2y
y = 65

Diameter:18
Volume:2544.69
Answer:
2,052,086,400.
Step-by-step explanation:
Permutation
Pr = n! / (n-r)!
30P5 = 30! / (30-5)
30P5 = 30x29x28x27x26x25! / 25!
(Just cancel the 25! on the numerator and denominator for easier solving.)
30P5 = 30x29x28x27x26
30P5 = 17,100,720.It is not the final answer because we can still arrange the 5 winners.
5! = 5×4×3×2×1 = 12017,100,720 × 120 = 2,052,086,400
