Two coplanar lines that are perpendicular to the same line are parallel.
a.) always
b.) sometimes
c.) never

Coplanar lines are lines that lie on the same plane.

Theorem: If two coplanar lines are perpendicular to the same  line, then the two lines are parallel to each other.

This theorem is true always, therefore, given statement is true always.

correct choice is A

the answer is c

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
