Mathematics

Answer:

32.8937 units

Step-by-step explanation:

So, we can imagine this as a right triangle with a length of 11 (THe change of the X's) and the height being 31 (Change of the Y's)

Then we use pythagorean therom to find the hypotenuse (the length)

11^2 + 31^2 = c^2

121+961 = C^2

1082 = c^2

Need help and NO LINKS!!!<br> Special Right Triangles (Radical Answers)
Nata [24]

Answer:

x = 5\sqrt{2}

Step-by-step explanation:

We know that;

The triangle is isosceles, and the hypotenuse is x, the un-labeled side is 5.

Therefore we can say;

5² + 5² = x²

25 + 25 = x²

50 = x²

\sqrt{50} = x

We can simplify this further;

\sqrt{25} * \sqrt{2} = \sqrt{50}

5\sqrt{2} = \sqrt{50}

Hope this helps!

A family plans a road trip from Fairbanks to Newbury. The distance between the two cities is 240 miles when traveling on the hig
alex41 [277]

Using proportions, it is found that the family will drive 482.8 km on the new route.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:

D = 1.25 x 240 = 300 miles.

Since there are are approximately <u>48.28 kilometers in 30 miles</u>, and 300/30 = 10, the distance in kilometers is given by:

D = 48.28 x 10 = 482.8 km.
