This forms a right triangle with 6 being the base and 10 being the hypotenuse.

Using the Pythagorean theorem solve the distance north, which would be the height of the right triangle.

X = √(10^2 - 6^2)

X = √(100-36)

X = √64

X = 8

The answer is 8 km.

Answer:

8 km

Step-by-step explanation:

Given : Runners in a long distance race start out going 6 kilometers east and then head north for the remainder of the race.

The finish line is 10 kilometers from the starting line.

To Find: How far did the runners travel north?

Solution :

Refer the attached figure

Runners in a long distance race start out going 6 kilometers east  i.e. AB = 6 km

The finish line is 10 kilometers from the starting line.i.e. AC = 10 km

We are supposed to find How far did the runners travel north i.e.CB

So, we will use Pythagoras theorem :

Hypotenuse^2=Perpendicular^2+Base^2

AC^2=CB^2+AB^2

10^2=CB^2+6^2

10^2-6^2=CB^2

\sqrt{10^2-6^2}=CB

8=CB

Hence the runners travel north is 8 km

Help me please! I need to find the answer for the angle indicated in bold!
bagirrra123 [75]

(x+ 63) + (x + 133) = 180 \\ 2x + 196 = 180 \\ 2x =  - 16 \\ x =  - 8 \\ so... \\ x + 133 = ( - 8 ) + 133  \\  = 125

If a box of 100 pencils cost $4.75, what should you expect to pay for 225 pencils?
skad [1K]

Answer:

$ 10.69

Step-by-step explanation:

225 is 2.25 times the 100 pencils. ( 225/100) So all you have to do is multiply 2.25 the price ($4.75) and you get 10.6875, money can only go to the tenth place so you round it to $10.69
