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

dunno

step-by-step explanation:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
