Point A is located at (1, 5), and point A′ is located at (-2, 1). What is the distance from B to B′ ?
babunello [35]

Answer:

The distance between B to B' is 5

Step-by-step explanation:

Using the distance lie formula:

Let's say (x2, y2) is (-2,1) and (x1, y1) is (1,5)

\sqrt{(x2-x1)^{2} +(y2-y1)^{2} } \\\sqrt{(-2-1)^{2} +(1-5)^{2} } \\\sqrt{(-3)^{2} +(-4)^{2} } \\\sqrt{9+16}\\\sqrt{25}    \\= 5

The distance between the original and new coordinates would be the same, therefore the two will remain a distance of 5.

PLEASE HELp tHHIS IS dUE IN AN HOUR!!!!! ITS MY LAST QuESTION Tony and Tiffany colleg\ct semi-precious stones. At the Rockhound
DIA [1.3K]

Answer:

Tiffany purchase the better buy.

Step-by-step explanation:

given data

Tiffany paid  = $38

snowflake obsidian = 9 pounds

Tony paid = $19

same type of stone = 3 pounds

solution

Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each

so for Tiffany

= $38 ÷ 9

= $4.22 per pound

and for Tony  

=$19 ÷ 3

= $6.33 per pound

so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound

so here whole $2.11 more than Tiffany

so that with this Tiffany purchase the better buy.
