A) Gabriela hace pulseras, sabe que el diámetro de la muñeca de sus clientas es de 5 cm y a la circunferencia de las pulseras que elabora le deja 3 cm para colocar los broches que permitirán cerrar la pulsera, ¿Cuántos centímetros de hilo para elaborar pulseras debe de comprar si tiene un pedido de 50 pulseras? cm de hilo por favor es my urgente

whatare you sayig

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
