Answer:
150.08 inches
Step-by-step explanation:
The question simply requires that we find the length of the arc that the dog walks.
Its leash rotates through 150° and the length of the leash (radius) is 60 inches.
The length of an arc is given as:
L = α/360 * 2πR
where α = angle of arc
R =radius
Therefore:
L = 150/360 * 2 * π * 60
L = 150.08 inches
The dog walks 150.08 inches
Answer:

Step-by-step explanation:

Represent charges with d and time with h
So:
when 
Required
Determine the formula

In other words,

Convert to an equation

Where
k = constant of proportion
Substitute values for Charges and Time

Solve for k


Substitute 15 for k in 


<em>The above formula models the situation</em>
Hello!
To find the area of a trapezoid you use the equation

Put in the values you know

Add

Divide

Divide both sides by 26
15 = h
The answer is 15km
