Kim ran total 7.1 miles.
Further explanation:
Front end estimation is the specific technique for rounding off numbers to estimates sums and differences. The numbers to be added or subtracted are rounded off to nearest one, tenth and hundredth.
So in the given scenario, we will round off to the nearest tenth.
So,
2.76 miles will be rounded off to 2.8 as the number right to the digit 7 is greater than 5, 7 will be rounded off to the next digit.
2.34 miles will be rounded off to 2.3 as the number right to 5 is less than 5, so 3 will be as it is.
1.97 miles will be rounded off to 2.0 as the number right to 9 is greater than 5 so it will be rounded off to the next number.
So, after estimation

A linear equation is an equation between two variables that gives a straight line when plotted on a graph.
Simple, to find the volume of a rectangular prism, just multiply the length by the height by the width. Like this:
3 x 4 x 5
The answer is 60.
S+d=209
d=209-s
6.5s+2d=836.5
6.5s+2(209-s)=836.5
6.5s+418-2s=836.5
4.5s+418=836.5
4.5s=418.5
s=93
There were 93 salads sold that day.
Consider the number 226981 since...
the units digit of 226981 is 1,
the units digit of its cube root is
also 1.
Now, the number obtained by striking out units, tens and hundred digits = 226.
=> 3. 3
<h2> 6. <226 <7 </h2>
tens digit of the cube root of 226981 is
<h2> 6</h2>
hence, 3._________
\/ 226981. =6
