Answer:
6 knots
Step-by-step explanation:
Let the speed be v knots
then time taken to cover 500 M = 500 / v hrs
fuel consumption /hr = 216 + 0.5v^3
let F be the fuel consumption for trip
= [500/v][216 + 0.5v^3]
= 500[216/v + 0.5v^2]
dF/dv = 500[ - 216/v^2 + v]
d^2F/d^2v = 500[432/v^3 + 1] , i.e. +ve
so setting dF/dv will give a minima
500[ -216/v^2 + v] = 0
or v = 216/v^2
or v^3 = 216
solving, we get v = [216]^(1/3) = 6 knots
Since 1000 mg is one g then the answer is .45 . So 450mg=.45g. Hope I helped.

Maria´s age=x-17
Orlando´s age=x
We can suggest this equation:
(x-17)+x=33
2x=33+17
2x=50
x=50/2
x=25
Maria´s age=x-17=25-17=8
Orlando´s age=x=25.
Answer: Maria is 8 years old, and Orlando is 25 years old.
