Erica scored 40 points on a test. this was 80% of the total possible score. find the total possible score. ( show the ! )

40=80%
divide both sides by 4 and you have:
10=20%
There are 5 20s in 100 so you multiply both sides by 5 so it is:
50=100%

Hope this helps :)

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
