Mercury is one of only two elements that are liquid at room temperature. Mercury is nonliquid for temperatures less than -38.0°F or greater than 673.8°F. Write a compound inequality for the temperatures
at which mercury is nonliquid.

greater than 673.8°F. Write a compound

Step-by-step explanation:

8496 cars

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."
