Answer:

  see attached

Step-by-step explanation:

We cannot really do the construction for you, but we can tell you how it needs to go. The three sides of the triangle will have a length in cm that is equal to the given length in km divided by 20.

  AB = 6 cm

  BC = 8 cm

  AC = 9 cm

__

The area each station can be heard will be a circle of radius (100 km)/(20 km) cm = 5 cm. The overlap of those circles is the area you are to shade.

The attached diagram should give you the general idea. (Scale units are cm.)

_____

<em>Additional comment</em>

It works well to find B as the intersection of arcs of radius 6 cm and 8 cm, drawn from centers A and C, respectively.

Blain is two years older than three times Jillians age. Jillian is also 16 years younger than Blain. How old is Blain?
Ipatiy [6.2K]

The age of Blain is 23 years old

<h3><u>Solution:</u></h3>

Let the age of Blain be "a" and age of Jillian be "b"

Given that Blain is two years older than three times Jillians age

So we can frame a equation as:

age of blain = 2 + 3(age of Jillian)

a = 2 + 3b ----- eqn 1

Also given that Jillian is also 16 years younger than Blain

Age of Jillain = Age of Blain - 16

b = a - 16 ---- eqn 2

Substitute eqn 2 in eqn 1

a = 2 + 3(a - 16)

a = 2 + 3a - 48

a - 3a = -46

-2a = -46

a = 23

Thus the age of Blain is 23 years old

Which would be a good estimate for the tax on $97.95 if the tax is 9.5%?
Ahat [919]
It would be $10. There is a formula to this "madness". Divide $97.95 by 9.5%. Ignore the rest of the numbers. (I'm pretty sure it has like 7 or 8, but I only went up to 3. Just make sure you have have the whole number, $10). Hope this helps.
