In the absence of ATC restriction on climb or descent, and aircraft are within 1,000 feet of assigned altitude. pilots should attempt to both climb and descend at a rate of between 500 fpm and 15000 fpm. (Option A)
An Air Traffic Controller (ATC) clearance refers to an authorization by ATC for the purpose of preventing known aircraft collision. The rate of climb or descend expected by ATV is when an aircraft is within 1000 feet of assigned altitude, descend, or climb at an optimum rate consistent with the operating characteristics of the aircraft to 1,000 feet above or below the assigned altitude, and then attempt to descend or climb at a rate of between 500 and 1,500 fpm until the assigned altitude is reached.

Step-by-step explanation:
1cm=50km
50cm*50km=2500km
Answer:
2500 km
Step-by-step explanation:
If 1 cm is equal to 50 km, we can multiply the 1 cm by 50 to get 50 cm. In order to do this, we also have to multiply the 50 km (which was equal to the 1 cm) by 50 as well.
50 x 50 = 2500

Where is the mean?, and Where is the median?Use point-slope form to write the equation of a line that passes through the point (13,5) with slope 1.
Answers
The equation of the line is y = x - 8 which passes through the point (13,5) with slope 1.
We have to determine the equation of a line that passes through the point (13,5) with slope 1.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Let the required line would be as
⇒ y - y₁ = m (x - x₁ )
The required line passes through the point (13, 5)
Here x₁ = 13 and y₁ = 5 and m = 1
Substituting these inputs into the above equation obtains the line equation.
⇒ y - 5 = (1)(x - 13)
⇒ y - 5 = (x - 13)
⇒ y = x - 13 + 5
⇒ y = x - 8
Thus, the equation of the line is y = x - 8 which passes through the point (13,5) with slope 1.

The amount of water left in the bathroom is 0.93 gallons
How to determine the amount of water left?From the question, the given parameters are:
Total amount of water in the bathroom = 7.2 gallonsAmount of eater drained out = 6.27 gallonsThe amount of water left is the difference between the total amount of water in the bathroom and the amount of eater drained out
This is represenetd as
Amount left = Total amount of water in the bathroom - Amount of eater drained out
Substitute the known values in the above equation
Amount left = 7.2 - 6.27

Here,
According to the question, the water left after the 6.27 gallons of draining out can be evaluated by the arithmetic subtraction of the initial volume to the volume that drained out, that is,
The volume of water left in the tub = 7.2 - 6.27 = 0.93.
