Given a standard day, at what altitude is the true airspeed of an aircraft approximately twice of what the airspeed indicator re
Yakvenalex [24]

Answer:

40000ftMSL

Step-by-step explanation:

We know that airspeed is measured using a pilot tube

And the air pressure is a function of density given as

Pressure= 1/2 xdensityx V²

So at 40,000ftMSL

Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level

So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above

An appliance store decreases the price of a 19-In television set 27% to a sale price of $471.58. What was the original price?
umka21 [38]
This means that $471.58 is equal to 100-27= 73% of the original price. We are trying to find 100%

$471.58/73= x/100

Cross multiplication method:
471.58*100= 47158
47158/73= $646=x

Final answer: $646.00
