In monetary terms, you're making change. If you need more ones, you trade one 10 for 10 ones.

When I was in school, many years ago, we used small superscript-type numbers to show this:

7 3 0 ⇒ 7 2 ¹0 . . . . regrouping to gain 10 ones

7 2 ¹0 ⇒ 6 ¹2 ¹0 . . .regrouping again to gain 10 more tens

You'd have to look at the example problems that precede this page in order to see what the meaning of "magnifying glass" is.

Answer:

The distance between the points (1, 7) and (10, 1) is 10.82 units

Step-by-step explanation:

Distance between two points

The distance between points A(x,y) B(w,z) can be calculated with the formula:

$d=\sqrt{(z-y)^2+(w-x)^2}$

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:

$d=\sqrt{(1-7)^2+(10-1)^2}$

$d=\sqrt{(-6)^2+(9)^2}$

$d=\sqrt{36+81}=\sqrt{117}\approx 10.82$

The distance between the points (1, 7) and (10, 1) is 10.82 units
