Your class is learning to tie knots. each student needs a piece of rope that is 3/8 yard long. how many yards of rope are needed for the 16 students in your class?

6 yards

Step-by-step explanation:

Given that one class is learning to tie knots

There are 16 students in the class.

Each student has to have a separate piece of rope to learn to tie knots.

Length of the piece of rope needed for each child = 3/8 yars

Hence total length required for all the  16 students would be

a direction variation question

So we multiply 16 by 3/8 to get

answer.

Answer = 16(3/8) = 6 yards

- "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."

its a, i had the same answer, its from study island right
