Fist we find the legnth of the diagonal
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
c=5
now the other diagonal
11^2+5^2=c^2
121+25=c^2
146=c^2
sqrt both sides12.083
closest is B
Answer:
Step-by-step explanation:
we subtract to find how much they saved, 40-24=16
now we divide 16 by 40 to get the percent 16/40 = 0.4
40%
Step-by-step explanation:
1. 64=1+3+5+7+9+11+13+15 that is a total of 8 odd numbers so n=8
2.((new-old)/old)×100%=percentual difference
so ((new-$55)/$55)×100%=20%
new-$55=$55×0.2
new=$55+$55×0.2=$66
