<h3>Answer: Approximately 4.47 km</h3>

The exact answer is 2*sqrt(5) but I figured it makes more sense to represent distance in terms of the approximate value. Round that however you need to. Your teacher may or may not want you to include the units, so be sure to ask.

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

Explanation:

This is similar to the previous question I answered earlier. Draw a vertical line straight down from point X until you reach line YZ. Mark point W on this vertical line, and that's also on line YZ.

Point W is the midpoint of YZ, which cuts it in half.

Let's focus on triangle WXY. It's horizontal leg is 8/2 = 4 km. Let a = 4.

For that same triangle, the vertical leg is unknown. We'll call it h. So b = h.

The hypotenuse of this right triangle is YX = 6 km. Let c = 6.

---------------

We have

  • a = 4
  • b = h
  • c = 6

Use the pythagorean theorem from here

a^2 + b^2 = c^2

4^2 + h^2 = 6^2

16 + h^2 = 36

h^2 = 36-16

h^2 = 20

h = sqrt(20)

h = sqrt(4*5)

h = sqrt(4)*sqrt(5)

h = 2*sqrt(5) ..... exact

h = 4.47213595  ..... approximate

h = 4.47 km

The distance is roughly 4.47 km

Sunny_sXe [5.5K]

Answer:

Kindly check explanation

Step-by-step explanation:

3 boxes or less = Cost of tiles = $48

4 - 8 boxes ;  cost = $45

9 - 19 boxes ; cost = $42

> 19 boxes ; cost = $38

Cost of purchasing 5 boxes of tiles :

$45 * 5 = $225

Cost of purchasing 19 boxes :

$42 * 19 = $798

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as kim's fish
MA_775_DIABLO [31]

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish. So, Doug caught a fish that was 3/5 meters long.

<h3>What is the fundamental principle of multiplication?</h3>

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish.

Kim caught a fish of length = 9/10 m

Doug caught a fish of length = 2/3 as long as Kim's fish.

                                                 = 2/3 x 9/10

                                                 = 18 / 30

                                                 = 3/5

Thus, Doug caught a fish that was 3/5 meters long.

alisha [4.7K]

Answer:

A: -11

B: Two complex solutions

Step-by-step explanation:

The discriminant of this equation is 3^2-20=9-20=-11. Since the discriminant is negative, its square root will be an imaginary number, and there will be two complex solutions. Hope this helps!
