I could be very wrong, but I believe the answer is C
This sequence starts with an initial set; let’s call it s1. This set contains 20 cans, and every set following would have two less cans than the last set. So,
s1=20
s2=s1-2=18
s3=s2-2=16
•

•
s9=s8-2=4
How many cans in the display represents the value of each set added together, so we can denote this as
s1+s2+s3+...+s9
and replacing with values:
20+18+16+...+4 = 108
The number of cans in the display equals 108.
(The set notation seems weird, but by practicing this application now, the Calculus version will seem easier.)
434 rounded to the nearest ten is 430.
Hope this helps
The answer is 70cm for the height because you would multiply 50cm x 35cm and you would get 1750. Then you would divide that by 122,500 and you will get the height
