Answer:
70m
Step-by-step explanation:
The ratio from 25 and 50 is 1/2 so 35x2 is 70m. This is equivalent to the given ratio.
Answer:Mean: 52.5
Median:54

Answer:
Step-by-step explanation:
Volume = πr²h/3 = πr²9/3 = 3πr²
3πr² = 3πy² + 30πy + 75π
r² = y² + 10y + 25
r² = (y+5)²
r = y+5
<span>sin(a+bi) = sina·coshb + i·cosa·sinh<span>b
sin(2+3i) = sin2·cosh3 + i·cos2·sinh3
so
u = sin2cosh3
v = cos2sinh3
