The average speed is based on more than one number. You take all the numbers( in this case speeds of people) add them and divide by the amount of numbers there are. This is how you get an average

It's related to both.

You can always definitely say that the average is greater than
the minimum and less than the maximum.

But that's ALL you can say is true about EVERY case.

The pilot of an airplane flying at an elevation of 5000 feet sights two trees that are 300 feet apart. If the angle of depressio

OLEGan [10]

Answer:

32°

Explanation:

From the diagrammatic representation of the question,

Point A is the pilot point of view from the airplane

Point C is the foot of the first tree

Point D is the foot of the second tree

Line AB is the height of the airplane from the ground level.

Line CD is the distance between the two trees

Considering ΔABC,

tan 33° $= \frac{5000}{BC}$

BC = 5000 / tan 33°

$BC = \frac{5000}{0.6494}$

BC = 7,699.41 feet

BD = BC + CD

BD = 7,699.41 + 300

BD = 7,999.41 feet

Considering ΔABD,

tan θ $= \frac{AB}{BD}$

tan θ $= \frac{5000}{7,999.41}$

tan θ = 0.6250

θ = tan⁻¹ 0.6250

θ = 32°

Suppose you have a car with a battery that applies 12.5 V to the starter.

Marat540 [252]

Answer:

R = 0.1 ohms

Explanation:

It is given that,

Voltage of the battery, V = 12.5 V

Current flowing in the car's starter, I = 125 A

We need to find the effective resistance of a car's starter. It can be calculated using Ohm's law. Let R is the resistance.

$V=IR\\\\R=\dfrac{V}{I}\\\\R=\dfrac{12.5}{125}\\\\R=0.1\ \Omega$

So, the resistance of the car's starter is 0.1 ohms.

Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance li

diamong [38]

So to solve this problem, we must convert units and then cancel units simultaneously:

$(\frac{982,080,000ft}{s})*(\frac{32,000,000s}{1})*(\frac{12inches}{1ft})=3.77x10^{17} inches$

Therefore we know that the distance that light travels in one year is $3.77x10^{17}$ inches.
