Answer:

-1 1/6

1 11/16

1 5/6.

Step-by-step explanation:

-5 5/6 ÷ 5

= -35/6 * 1/5

= -7/6

= - 1 1/6.

-4 1/2 ÷( -2 2/3)

= -9/2 / -8/3

= -9/2 * -3/8

= 27/16

= 1 11/16.

-6 7/8 ÷ (-3 3/4)

= -55/8 / -15/4

= -55/8 * -4/15

= 11/6

= 1 5/6.

Micah places a mirror on the ground 24 feet from the base of a tree. He walks

irina [24]

The height of tree is 8 feet

<h3><u>Solution:</u></h3>

Given, Micah places a mirror on the ground 24 feet from the base of a tree

At that point, Micah's eyes are 6 feet above the ground

And he is 9 feet from the image in the mirror.

To find : height of tree = ?

Let "n" be the height of tree

From the question, we can see there is a directly proportional relationship between heights and distances.

Proportional relationships are relationships between two variables where their ratios are equivalent.

$\frac{\text { height of micah eyes above ground }}{\text { distance of micah from mirror }}=\frac{\text { height of tree above the ground }}{\text { distance of tree from mirror }}$

$\begin{array}{l}{\frac{6 \text { feet }}{9 \text { feet }}=\frac{n \text { feet }}{24 \text { feet }}} \\\\ {\frac{6}{9}=\frac{n}{24}} \\\\ {\text { n }=\frac{1}{3} \times 24} \\\\ {\text { n }=8}\end{array}$
