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.
Hence, the height of the tree is 8 feet

Step-by-step explanation:
To find the amount of profit earned in each product,apply the percent profit formula;
%profit= profit/original price *100
<u>a)Candy </u>
% Profit =65%
Selling price = $6400
This means;
165%=6400
100%=?
Cross multiply
(100*6400)/165 =$3878.80
Original price= $3878.80
Profit= $6400-$3878.80
=$2521.20
<u>b)Wrapping Paper</u>
%profit= 40%
Selling price= $1200
This means;
140%=$1200
100%=?
Cross-multiply
(1200*100)/140=$857.14
Original price=$857.14
Profit=$1200-$857.14
=$342.90
<u>c)Stationery</u>
%profit= 50%
Selling price =$900
This means;
150%=900
100%=?
Cross-multiply
(900*100)/150 = $600
Original price = $600
Profit= $900-$600=$300
<u>d)Calender's</u>
%Profit=25%
Selling price=$3120
This means;
125%=$3120
100%=?
Cross-multiply
(100*3120)/125=$2496
Original Price=$2496
Profit= $3120-$2496=$624
2)
Selling price for pens and pencils =$4500
%percent profit earned = 42%
Profit earned will be:
142% = $4500
100%=?
Cross-multiply
(100*4500)/142 =3169.01
Original price=$3169.01
Profit= $4500-$3169.01
=$ 1331

Q = d - 12
q = 28 - d
d - 12 = 28 - d
d + d = 28 + 12
2d = 40
d = 40/2
d = 20 <== 20 dimes
q = d - 12
q = 20 - 12
q = 8 <== 8 quarters
