The table shows the distance the students a group of students walked during after-school practice. What was the total distance,

ser-zykov [4K]

First let's convert the decimal numbers to mixed numbers:

$\begin{gathered} 3.4=3+0.4=3+\frac{4}{10}=3+\frac{2}{5}=3\frac{2}{5} \\ 1.75=1+0.75=1+\frac{75}{100}=1+\frac{3}{4}=1\frac{3}{4} \\ 2.25=2+0.25=2+\frac{25}{100}=2+\frac{1}{4}=2\frac{1}{4} \end{gathered}$

Now, adding all the numbers, we have:

$\begin{gathered} (3+\frac{2}{5})+(3+\frac{1}{5})+(1+\frac{3}{4})+(2+\frac{1}{4})+(1+\frac{7}{10}) \\ =(3+3+1+2+1)+(\frac{2}{5}+\frac{1}{5}+\frac{3}{4}+\frac{1}{4}+\frac{7}{10}) \\ =10+(\frac{3}{5}+1+\frac{7}{10}) \\ =11+(\frac{6}{10}+\frac{7}{10}) \\ =11+\frac{13}{10} \\ =12+\frac{3}{10}=12\frac{3}{10} \end{gathered}$

So the correct option is B.

Answer:

5.14

Step-by-step explanation:

The way i solved this was i found the length of the line by taking the 2 (Width and also "A") and the 7 (The height and also "B"), squared both of them and added them together. Then found the square root. Sense i suck at explaining things this is what the equation should have looked like. $\sqrt{(2^{2} +7^{2})$ ÷ 2. (Side wait for someone else to answer because i'm 70% sure this is right.
