Se tiene 50 estudiantes en un examen: 1-Calcular la cantidad de alumnos con calificación de menos que 59

2- Que cantidad de mantiene en media 60-80

3-Que porcentaje hay del 81 al 100

2

step-by-2step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
