Miguel, José y Adrián practican ciclismo en un velódromo de 250 metros de longitud. Miguel dio seis vueltas, José cinco vueltas y Adrián tuvo un fuerte calambre al empezar, así que solamente hize + partes de una vuelta. ¿Cuántos metros recorrió Miguel? ¿Cuántos metros recorriá José? ¿Cuántos metros son la quinta parte de 250 m ? Entonces, ¿cuántos metros son metros recorrió Adrián

1) Escribir la siguiente matriz: \( D=\left(d_{i j}\right)_{5 \times 4^{\prime}}, \quad d_{i j}=\left\{\begin{array}{rr}-2 & \text { si } i \leq j \\ 0 & \text { si } i \geq j\end{array}\right\} \)

Matrices and systems.. Badrul is currently camping in a jungle. He left his adventure. On the first day he went 5 mile his second day, he moved 8 miles to the ast an he ventured 3 miles east and 8 miles north Ass (a) Badrul location in coordinate after three (b) the total displacement Badrul made adventure. (c) the angle relative to the eastern direct b) \( \sqrt{(19)^{2}+(16)^{2}}=617 \)

8. Which is the conclusion of the conditional? A A number is an integer. B A number is either a whole C number or an integer. A number is a both a whole D A number and an integer.

9. Which is the hypothesis of the conditional? A A number is an integer. B A number is both a whole C number and an integer. A number is either a whole D A number or an integer.

Order these numbers from least to greatest. \[ \frac{4}{17},-\sqrt{18}, 0.25,-\frac{86}{20} \]
