How many digits will be to the right of the decimal point in the product?

1.456 × 84

6

Step-by-step explanation:122.304

3

Step-by-step explanation:

There will be 3 digits to the right of the decimal point for this expression because 84's decimal point is right between the tenths and units. If it was between the units and tens, then there would have been 2. Tens and hundreds, then there will be 1 and so on. Tenths and Hundredths would make 4 decimal points. That was pretty badly explained but I hope that helped you :D

step-by-step explanation:

b and c

- "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."
