The teacher in item 10 also needs to order plastic tubing. if each of the 60 students need 750 mm of tubing, what length of tubing in meters should the teacher order?

45 m. If each student needs 750 mm of tubing, the teacher should order 45 m of tubing.

a)Find the length in millimetres

Length = 60 students x (750 mm tubing/1 student) = 45 000 mm tubing

b)Convert millimetres to metres

Length = 45 000 mm tubing x (1 m tubing/1000 mm tubing) = 45 m tubing

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
