Fofino [41]
------------------------------------------------------------------------------------
Reduced (simplify) all factions if possible
------------------------------------------------------------------------------------

(1/4 cannot be reduced)
1/4 = 1/4

(divided by 2 for both numerator and denominator)
2/8 = 1/4

(divide by 3 for both numerator and denominator)
3/12 = 1/4

------------------------------------------------------------------------------------
Find combined fraction of the mural that has been painted.
------------------------------------------------------------------------------------
1/4 + 1/4 + 1/4 = 3/4

------------------------------------------------------------------------------------

If a diameter intersects a chord of a circle at a perpendicular, what conclusion can be made?
Agata [3.3K]

If a diameter intersects a chord of a circle at a perpendicular then the chord is bisected.

<h3>What is the relation between the chord and diameter of a circle?</h3>
  • The segments of a circle whose endpoints are on its perimeter are called chords.
  • A circle's diameter is the chord that passes across its center.
  • The circle's longest chord equals its diameter.
  • Any line that is perpendicular to a chord on the circle cuts it in half and goes through the center.

The solution to the problem:

A circle's chord is intersected perpendicularly by its diameter, which also passes through the center of the circle. The chord and diameter are perpendicular. Any line that is perpendicular to a chord on the circle and passes through its center divides it. The chord is divided equally by the diameter.

Therefore, the chord is bisected.
