-9 is the answer. 1/4 of 12 is 3, and their negatives cancel each other. Then you just multiply -3 by 3.

There are still other ways to make<span> the same comparison, by using </span>equal ratios<span>. To find an </span>equal ratio<span>, you can either multiply or divide each term in the </span>ratio<span> by the same number (but not zero).

Harvey flew south 300 miles. He changed planes and then flew east 500 miles. If he travels a straight path back home, how many m
Andrews [41]

Answer:

583 miles

Step-by-step explanation:

Let's draw this out (see attachment).

The straight line path creates the hypotenuse of a right triangle with legs of lengths 300 and 500. So, we use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:

a² + b² = c²

Here, a = 300 and b = 500. Then:

300² + 500² = c²

90000 + 250000 = c²

340000 = c²

c = √340000 ≈ 583.1 ≈ 583 mi

Thus, the answer is 583 miles.

Find the height of the triangle by applying formulas for the area of a triangle and your knowledge about triangles.
neonofarm [45]

Using the Pythagorean Theorem, the altitude to side c has a length of 11.3 inches.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

To find the altitude relative to side c, we bisect this side, which cuts it's length into half(now of 4 inches), forming a right triangle in which:

  • The altitude is the other leg.
  • The side of 12 inches is the hypotenuse.

Hence:

x^2 + 4^2 = 12^2

x = \sqrt{12^2 - 4^2}

x = 11.3 inches.

If BC = 5x − 15, CD = 4x, and BD = 8x + 4, what is BD? Simplify your answer and write it as a proper fraction, mixed number, or
hichkok12 [17]

Answer:

156

Step-by-step explanation:

CD+BC=BD

(5x - 15) + 4x = 9x - 15 = 8x + 4 \\ x = 19 \\ bd = 8x + 4 = (8 \times 19) + 4 = 156
