Find the incenter of the triangle.
Draw a perpendicular from the incenter to one of the sides. Mark the point of intersection with the side.
Set the distance between compass points to the distance between the point of intersection and the incenter. This is the radius of the circle

If it costs $16.50 to bowl twice with a shoe rental and $28.50 to bowl 4 times with a shoe rental how much does the shoes cost
Dmitry_Shevchenko [17]

Answer:

Shoe rent is $4.5

Step-by-step explanation:

Let the shoe rent is "x" which will remain the same irrespective of the number of bowling and "y" is bowling.

thus, x + 2y = 16.50

Rewrite, x = 16.50 - 2y

When bowling is 4 time then:

x + 4y = 28.50

Rewrite, x = 28.50 - 4y

Now solve both equations for the value of "y".

Thus, 16.50 - 2y = 28.50-4y

-2y + 4y = 28.50 - 16.50

2y = 12

y = 6

Insert y = 6 in the x - 2y = 16.50

x = 16.50 - 2y

x = 16.50 - 2 (6)

x = $4.5

Shoe rent is $4.5

Kitty [74]

For this case we have the following apple picking options, in dozens:

<em>Tyler:</em>

\frac {3} {3} = 1

Tyler picked up a dozen.

<em>Olivia:</em>

\frac {5} {6} = 0.833

Olivia collected 0.833 dozen apples.

<em>Samantha:</em>

\frac {2} {3} = 0.667

Samantha collected 0.667 dozens of apples.

Thus, it is observed that Samantha collected the least amount of apples.
