Round off 5698 and 8236to the nearest tens. After rounding them off, add them. Then, Round off the sum to the nearest hundred. What do you get?

13900

Step-by-step explanation:

Round off 5698 to it nearest tens

5700

Then Round off 8236 to its nearest tens

8240

Add up 5700 + 8240 = 13940

Round off 13940 to its nearest hundred

13900

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

- "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."
