Answer:

<em>d </em>= 5.65685 or 5.66

Step-by-step explanation:

Given the points (1, 3) and (5, 7), we can use the following distance formula:

d = \sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}

Let x 1 = 1

x2 = 5

y1 = 3

y2 = 7

d = \sqrt{(5 - 1)^2 + (7 - 3)^2}

d = \sqrt{(4)^2 + (4)^2}

d = \sqrt{16 + 16}   = \sqrt{32}

d = 5.65685 or 5.66

Daniel is planning a 6-night road trip. It will cost $310 for transportation, $275 for food, and $70 per night for a hotel room.
Anna11 [10]

Answer:

Daniel must tutor 160 hours

Explanation:

310+275+70= 655

655×6= 3930 (he needs this amount of $)

(Daniel gains $20 per hour)

20×160= 3200

3200+745= 3945

3945 > 3930

Daniel has enough for the trip.

Where did I get 160?

Well, I was just trying out numbers and multiplying it by 20

The numbers I tried: 100, 150, 156, 159 & 160 but only 160 fit with the answer.

If it was just one night road trip he would've just needed $655, but since it's a 6-night road trip I multiplied it by 6.

Hope this helped!
