Alicia drew a map of Texas. In the scale Alicia used for the map, .50 inch represents 20 miles. What is the distance between two
kramer

Answer:

An actual distance of 360 miles correspond to 9 inches on the map

Step-by-step explanation:

From the question, we have a scale of 0.5 inches representing 20 miles

Now, we want to relate an actual distance of 360 miles to a measurement on the map using the scale

From here, we have that;

0.5 inches = 20 miles

x inches = 360 miles

x * 20 = 0.5 * 360

20x = 180

x = 180/20

x = 9 inches

Cd has an endpoint at (2, -1) and a midpoint at (8, 3). which measure is closest to the length of cd
stepladder [879]

Answer:

4\sqrt{13}

Step-by-step explanation:

The length of CD will be twice the distance from the midpoint to the endpoint

To calculate the length use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (8, 3)

d = 2 × \sqrt{(8-2)^2+(3+1)^2}

  = 2 × \sqrt{6^2+4^2}

  = 2 × \sqrt{52}

  = 2 × \sqrt{4(13)}

  = 2 × 2\sqrt{13} = 4\sqrt{13} ← exact length
