If a machine can produce 85 parts in 40 minutes, how many parts can it produce in 8 hours

We need to see how many in 1 minute

85/40 = 2.12

Now we need to see how many in 60 minutes (1 hour heehee)

2.12 x 60 = 127.2

Now in 8 hours

127.2x8 = 1017.6

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
