Answer:
5%
Step-by-step explanation:
38/40 = x/100
38*100 = 3800
3800/40 = 95
95/100 = 38/40
38 is 95% of 40 therefore the change is 5%
Suppose the three sides are a, b, and c, with c being the longest, a being the shortest
first equation: c=(a+b)-66
second equation: 2a=c-55=> c=2a+55
plug c=2a+55 into the first equation: 2a+55= a+b-66 => b=a+121
a+b+c=a+(a+121)+(2a+55)=7272 =>4a+176=7272 =>a=1774
a=1774, b=1895, c=3603
Since this is a permutation, it would be 5!(factorial)
so 5x4x3x2x1
Jack drove the fastest with 31.25 miles and that rounded to the nearest whole number is 31.
She will ride a total of 26 miles of 8 weeks.
