When a coordinate grid is superimposed on a map of lanesville the middle school is located at (15,13) and the librart is located
Maksim231197 [3]

Answer:

4.5 miles

Step-by-step explanation:

Given

Middle\ School = (15,13)

Library = (27,9)

To solve this, we simply solve for the distance (D) between both points.

D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Where:

(x_1,y_1) = (15,13)

(x_2,y_2) = (27,9)

D = \sqrt{(27 - 25)^2 + (9 - 13)^2}

D = \sqrt{(2)^2 + (-4)^2}

D = \sqrt{4 + 16}

D = \sqrt{20}

D=4.472135955

<em></em>D=4.5<em> --- approximated</em>

<em>Since each unit is 1 mile. The distance is 4.5 miles</em>

Solid A is similar to Solid B. If the volume of Solid A is 3,240 meters cubed
irina [24]

Option B: 36 : 1 is the ratio of the surface area of Solid A to Solid B

Explanation:

Given that the Solid A is similar to Solid B.

The volume of Solid A is 3240 m³

The volume of Solid B is 15 m³

We need to find the ratio of the surface area of Solid A to Solid B.

Thus, we have,

\frac{SA \ of \ Solid A}{SA \ of \ Solid B}=\sqrt[3]{\frac{3240}{15}}

Dividing the terms, we get,

\frac{SA \ of \ Solid A}{SA \ of \ Solid B}=\sqrt[3]{\frac{216}{1}}

Taking cube root, we get,

\frac{SA \ of \ Solid A}{SA \ of \ Solid B}=\frac{6}{1}

Squaring the ratios, we get,

\frac{SA \ of \ Solid A}{SA \ of \ Solid B}=(\frac{6}{1})^2

\frac{SA \ of \ Solid A}{SA \ of \ Solid B}=\frac{36}{1}

Thus, the ratio of the surface area of Solid A to Solid B is 36 : 1

Hence, Option B is the correct answer.
