Similar example: if 1 inch = 50 miles then 3 inches on a map would mean... 1 inch/50 miles = 3 inches/x miles or just 1/50 = 3/x
jim_thompson5910
  • jim_thompson5910
so you can use that to find the actual distance x that 3 inches represents on a map

okay for the first one I got B as my answer and the second question I got C
jim_thompson5910
  • jim_thompson5910
why B for the first one?
jim_thompson5910
  • jim_thompson5910
you know the distance on the paper map, it's 7 inches it's not z inches
jim_thompson5910
  • jim_thompson5910
z is the unknown distance in real life from point A to point B that the 7 inches represents on the paper map

i meant to write z miles, not z inches
jim_thompson5910
  • jim_thompson5910
but hopefully you get the idea
jim_thompson5910
  • jim_thompson5910
the scale is this |dw:1364427313903:dw|

oh first on is C huh?
jim_thompson5910
  • jim_thompson5910
put the two side by side to get |dw:1364427383477:dw|
anonymous
  • anonymous
yep so its C!:)
jim_thompson5910
  • jim_thompson5910
yep, C it is
jim_thompson5910
  • jim_thompson5910
1 inch/10 miles = 7 inches/z miles or just 1/10 = 7/z

alright how about second one?
jim_thompson5910
  • jim_thompson5910
we want arc RF, so we need to find central angle FDR
jim_thompson5910
  • jim_thompson5910
to find the central angle, you use the inscribed angle theorem
jim_thompson5910
  • jim_thompson5910
this central angle here |dw:1364427601352:dw|
jim_thompson5910
  • jim_thompson5910
is equal to 2 times any inscribed angle which cuts off the same arc

  • anonymous
alright so my answer would be D
jim_thompson5910
  • jim_thompson5910
yep 76
