Answer:

13

Step-by-step explanation:

12 - 0 = 12

0 - 5 = -5 which is same as 5 here

12^2 + 5^2 = 144 + 25 = 169

sqrt 169 = 13

<h3>Answer: 13</h3>

==========================================================

Explanation:

We have the two points (x_1,y_1) = (0,0) and (x_2,y_2) = (12,-5)

Apply the distance formula to them.

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\&#10;d = \sqrt{(0-12)^2 + (0-(-5))^2}\\\\&#10;d = \sqrt{(0-12)^2 + (0+5)^2}\\\\&#10;d = \sqrt{(-12)^2 + (5)^2}\\\\&#10;d = \sqrt{144 + 25}\\\\&#10;d = \sqrt{169}\\\\&#10;d = 13\\\\

The distance from Sara's house to the school is exactly 13 km.

An alternative is to use the pythagorean theorem. The distance formula is effectively based on this theorem.

To check the answer, you can use a tool like GeoGebra to plot the two points given. Then draw a segment between them. It should show "13" as the segment length. That app also has a "distance" tool as an alternative. So there are a few ways to get the answer, and to check it as well.

Two trains are traveling towards each other at a constant speed. The trains are currently 714 miles from each other. The speeds
shutvik [7]
55mph.

you can solve it using the equation distance=speed x time

your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours. 
your equation would look like this
714 = x(7) + (x+8)(7)
and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.

There are 416 students who are enrolled in an introductory geology course. if there are seven boys to every six girls, how many
Alenkinab [10]

\text{Let the number of boys be x and number of girls be y.}\\&#10;\\&#10;\text{and there are total 416 students enrolled in the course. so we have}\\&#10;\\&#10;x+y=416 \ \ \ \ \ \ \ \ \ \ ......(i)\\&#10;\\&#10;\text{also given that there are seven boys to every six girls, that is}\\&#10;\\&#10;\frac{x}{y}=\frac{7}{6}

\Rightarrow 6x=7y\\&#10;\\&#10;\Rightarrow y=\frac{6x}{7}\\&#10;\\&#10;\text{substitute this value of y in (i), we get}\\&#10;\\&#10;x+\frac{6x}{7}=416\\&#10;\\&#10;\Rightarrow \frac{7x+6x}{7}=416\\&#10;\\&#10;\Rightarrow \frac{13x}{7}=416\\&#10;\\&#10;\Rightarrow x=\frac{416\times 7}{13}\\&#10;\\&#10;\Rightarrow x=224

Hence the number of boys in the course are: 224
