Find the distance between the pair of points (2,9) and (3,8).

xxTIMURxx [149]

Answer:

$\sqrt{2}$ units

Step-by-step explanation:

To find the distance between a pair of points, use the distance formula, $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Substitute the x and y values of (2,9) and (3,8) into the formula and simplify:

$d = \sqrt{(8-9)^2+(3-2)^2} \\d = \sqrt{(-1)^2+(1)^2} \\d = \sqrt{1+1} \\d= \sqrt{2}$

So, the distance is $\sqrt{2}$ units.

two brands of potato chips reduced the fat content of their chips . brand a had 8 grams of fat per savings and reduced fat by 30

9966 [12]

8 grams reduced by 30%....if it is reduced by 30%, then there is a total of 70%

70% of 8.....turn ur percent to a decimal..." of " means multiply
0.70 * 8 = 5.6 grams <==

10 grams reduced by 40%.....so it contains 60%
60% of 10 =
0.60 * 10 =
6 grams <==

so brand A, the 8 grams reduced by 30%, now has less fat <==
