<span>πd is the circumference of a circle, so with a diameter of 4 a single circle has a circumference of 4π. 1/3 of each circle is in contact with the belt, so that total part is still 4π. Then, the part of the belt connecting from tangent to tangent is 2 radii, so 3 areas is 12. The belt would then be 12+4π cm.</span>

Four eighths of Kelly's beads are red, 1 8 18 are white, and the rest are blue. What fraction of Kelly's beads are blue?
Setler79 [48]

Answer:

1/38 of Kelly's beads are blue.

Step-by-step explanation:

four eighths = 1/2 or 1 half

1/2 of them are red.

18 white beads, so number of red beads have to be bigger than 18 since she has blue beads too.

So, we can just estimate she has just one blue bead so then the 18 whites become 19 so we need to make red beads the same amount as it is half of the total.

The total is 38 since 19 + 19 = 38 (total beads)

So, blue is 1/38 as a fraction.

Hope this helps. :)

lana66690 [7]

Answer:

<em>( </em>-\frac{1}{2}<em> , </em>\frac{3}{2}<em> )  </em>

Step-by-step explanation:

( x_{1} , y_{1} )

( x_{2} , y_{2} )

Coordinates of midpoint are

( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )

~~~~~~~~~~~~~~~~~~~~

The figure is right triangle.

The circumcenter is the middle of the hypotenuse.

( - 2, 4 )

( 1 , - 1 )

<em>( </em>-\frac{1}{2}<em> , </em>\frac{3}{2}<em> ) </em>
