Answer: Longest distance she could measure is 70 mm
Step-by-step explanation:
To find the longest distance from one side to other across the center we have to find the diameter of the lampshade.
As it is given that the distance around the lampshade is 219.8 mm which is equal to the circumference of the lampshade.
Circumference of the lampshade is
πD, where D is the diameter of the lampshade
where the value of π=3.14
Divide both sides by 3.14 we get

on solving we get

I believe it is B because the y intersect is +6 and they slope is going down so it is -2
Usando un sistema de ecuaciones, se encuentra que la rapidez inicial del primer ninõ es 4.95 m/s.
-------------------------
- Consideramos que la rapidez inicial de el primer ninõ es x, y de el segundo es y.
El primer niño rebota <u>1.5 veces más alto que el segundo</u>.
O sea:

La rapidez inicial del segundo niño es de 3.3 m/s.
Esto implica que 
¿Cuál es la rapidez (m/s) inicial del primer niño?

La rapidez inicial del primer ninõ es 4.95 m/s.
