Amale elephant weighs 6,728 pounds. a female

elephant weighs 5,843 pounds. to the nearest hundred, what is

the total weight of the two elephants?

12,600 pounds.

Step-by-step explanation:

Given,

The weight of male elephant = 6728 pounds,

The weight of female elephant = 5843 pounds,

So, the total weight of these two elephants = 6728 + 5843 =12571 pounds,

∵ Tens place digit of 12571 = 7,

Also, if tens place in a number is 7 so, the number would be rounded to the next hundred,

That is, 12571 ≈ 12600

Hence, the total weight of the elephants is 12600 pounds.

b

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."
