Copies. A teacher has to make 159 copies of a review packet for the students in her classes. When she arrives in the workroom, she starts using both copy machines (call them X and Y).
During the copying, machine X runs out of paper, so it only printed half as many packets as
copier Y. How many copies does each machine print?

Step-by-step explanation:

The ratio of copies printed is ...

  X : Y = 1 : 2

so the ratio of the number printed by machine X to the total is ...

  X : (X+Y) = 1 : (1+2) = 1 : 3

1/3 of the 159 copies were printed by machine X, so it printed ...

  (159)(1/3) = 53

Twice that many were printed by machine Y, so it printed ...

  2·53 = 106

Machine X printed 53 copies; machine Y printed 106 copies.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
