An aircraft is flying at a constant altitude with a constant speed of 600 miles per hour. An antiaircraft missile is fired on a straight line perpendicular to the flight path of the aircraft so that it will hit the aircraft at a point P. At the instant the aircraft is 2 miles from the impact point P, the missile is 4 miles from P and flying at 1200 miles per hor. At that instant, how rapidly is the distance between the missile and aircraft decreasing?

How do you find the slope of a line when the line doesn't have any coordinates? I know that the slope of a line is the coefficient of x in the equation but what is a coefficient? I already know what a y-intercept is, but I don't know how to find the slope. =D

The direct conversion of H2 and N2 gases at high pressure using a catalyst is:

N2 + 3H2 <--> 2NH3

How many liters of 2NH3 can be obtained using 27.7L of N2 and 102.3L of H2? Assuming complete conversion and constant pressure of 500 atm and constant temperature of 500 K.

I'm really stuck on this problem, any help would be appreciated.

Mortar is made by mixing 4 parts sand to 1 part cement. A builder uses 100kg of sand.

How much cement must he use?

I thought it was 25kg, but I think thats wrong.

(sorry, this is probably really easy, but I'm rubbish at Maths)!!

Some hotels have glass elevators on the outside of the building. One such hotel is 300 feet high. You are looking out a window 100 feet above the ground in a building 150 feet away from the hotel, as the elevator descends at a constant speed of 30ft/sec, starting at the top of the hotel at time t = 0 sec. Let Ө be the angle between your horizontal line of vision and your line of sight to the elevator.

The rate of change of Ө is a measure of how fast the elevator appears to you to be moving. At what height above the ground does the elevator appear to be moving fastest?
