The Sears Tower in Chicago, Illinois is 1,454 feet tall. Its twin antennas reach an additional 253 feet. If a souvenir shop sells a replica of the Sears Tower that is 9 inches tall, how tall are the twin antennas on the replica?

0.13 in
0.09 in
1.57 in
0.15 in

ok so im not a math expert but i can tell you they are spliting the antenas by the same as the towers. you devide original size by 9 and thats simplest form to see how much an inch shows per inch. but for full answer you add the amounts together 9 times (the amounts you got after deviding of course) ill let you do that math from there... thats how i got my answer... but im just going off my work. so i hope im correct im confadent i am.

the height doesn't include the antenna
rato and protoprion

height:antana=1454:253=1454/253
1454/253=9/x
cross multiply and solve for x
1454x=2277
divide both sides by 1454
x=1.56602
round
x=1.57

answer is 3rd option, 1.57 inches
