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.

sweet [91]

Answer:

She work 23 hours.

Step-by-step explanation:

Given:

Tracy works at the Pizza Place. She earns $4.50 an hour plus tips.

Last week, she earned a total of $156.00, of which $52.50 was tips.

Now, to find the number of hours she work.

Total salary = $156.00

Amount of tips = $52.50.

So, first we deduct the amount of tips from the total salary:

$\$156.00-\$52.50\\=\$103.50.$

Thus, the remaining salary = $103.50.

As, given salary she earns an hour = $4.50.

And then, to get the number of hours she work last week by dividing $103.50 the remaining salary by $4.50:

$103.50\div 4.50$

$=23\ hours.$

Therefore, she work 23 hours.
