A= sides2
98=sides2
√98 = √(〖sides〗^2 )
Side= 9.8994
Now the Pythagorean theorem
a2 + b2 = c2
9.89942 + 9.89942 = c2
97.99812036+ 97.99812036 = c2
c2 = 195.99624072
c= 13.99
Rounded to the nearest whole number is 14
A. 14 m

Jenna is running a trail that is 8 4/7 miles long. If she has finished running 5/9 of the distance, about how far has she run?

Varvara68 [4.7K]

Answer:

Jenna has run the distance of $\frac{100}{21}$ miles .

Step-by-step explanation:

The Distance for the trail = 8 $\frac{4}{7}$ = $\frac{56+4}{7}$

Or , Distance = $\frac{60}{7}$ miles

The distance cover by Jenna = $\frac{5}{9}$ miles of the distance

I.e The distance cover by Jenna = $\frac{5}{9}$ × $\frac{60}{7}$

Or, The distance cover by Jenna = $\frac{100}{21}$ miles

Hence Jenna has run the distance of $\frac{100}{21}$ miles . Answer
