Answer:
Point O is the center of the circle.
<u>Part (a)</u>
is a chord.
is a segment of the radius and is perpendicular to 
If a radius is perpendicular to a chord, it bisects the chord (divides the chord into two equal parts).
Therefore, 
<u>Part (b)</u>
If
was extended past point E to touch the circumference it would be a chord.
As
is perpendicular to
, it would bisect the chord, but as
is only a portion of a chord,
<u>does not</u> bisect
.
Therefore, there is no length equal to
.
1000milimeter=1meter
divide both sides by 1000
1mm=1/1000m
times both sides by 254
254mm=254/1000m
254mm=25.4/100m
254mm=2.54/10m
254mm=0.254/1m
254mm=0.254m
it is 0.254 meters

<em>Equation, variable, value, clear
</em>
For this case we have an equation with a variable of the form
. Where
. Given the value of
, we want to find the value of the variable "x". So, we have:

We must clear "x", for this, we add "19" to both sides of the equation:

We divide between "3" on both sides of the equation:

Thus, the value of the variable "x" is 30.
Answer:

Option A
All I could think is subtract and divide
Answer:
Half of the persentage were large.
Step-by-step explanation:
So if you do 60 divided by 2, which is 30, and 30 of the buttons are large, then half of 60, (30) are large
