On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7). Mary walks on a straight line from her

FrozenT [24]

The ordered pair that represents the halfway point between Mary's home and the grocery store is (1, 4)

The midpoint (a, b) between two linear points $(x_1, y_1)$ and $(x_2, y_2)$ is calculated as:

$a=\frac{x_1+x_2}{2} \\\\b=\frac{y_1+y_2}{2}$

On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7).

$x_1=-3, y_1=1, x_2=5, y_2=7$

Substitute these values into the mid-point formulae

$a=\frac{-3+5}{2} \\\\a=\frac{2}{2}\\\\a=1$

$b=\frac{1+7}{2} \\\\b=\frac{8}{2}\\\\b=4$

The ordered pair that represents the halfway point between Mary's home and the grocery store is (1, 4)

In the image below, 10 is the long leg of the 30-60-90 triangle.<br><br><br> True or false?

never [62]

The measure of the angle between the hypotenuse and the <em>short</em> leg is 60° and we can conclude that the side with length 10 is not the <em>long</em> leg of the 30 - 60 - 90 <em>right</em> triangle. (Right choice: False)

<h3>Is the length of a known arm in a 30 - 60 - 90 right triangle the long arm?</h3>

In accordance with geometry, the length of the <em>long</em> arm of a 30 - 60 - 90 <em>right</em> triangle is √3 / 2 times the length of the hypotenuse, the length of the <em>short</em> arm is 1 / 2 times the length of the hypotenuse and the length of the <em>long</em> arm is √3 times the length of the arm.

Thus, the measure of the angle between the hypotenuse and the <em>short</em> leg is 60° and we can conclude that the side with length 10 is not the <em>long</em> leg of the 30 - 60 - 90 <em>right</em> triangle. (Right choice: False)

Quadrilateral ABCD is similiar to quadrilateral EFGH. The lengths of the three longest sides in quadrilateral ABCD are 60 feet,

babunello [35]

Answer:

15 feet

Step-by-step explanation:

It is given that Quadrilateral ABCD is similar to Quadrilateral EFGH. This means that the corresponding sides of these two quadrilateral will be in the same proportion.

i.e.

Ratio of two corresponding sides would be the same. We are given longest three sides of ABCD and shortest two sides of EFGH. Let the 4th sides of ABCD i.e. the shortest side be x.

So, the ratio of the shortest sides of two quadrilaterals would be the same as the ratio of second shortest sides.

So,

$x:6=30:12\\\\\frac{x}{6}=\frac{30}{12}\\\\ x=\frac{30}{12} \times 6\\\\ x = 15$

So, the 4th side on quadrilateral ABCD would be 15 feet. None of the options match with the answer.
