(a)=16
First you do 42*8. Then 42*8=336. Divide 336 by 21 to find (a) which equals 16.
(r)=5
First you do 105*8. Then 105*8= 840. Divide 840 by 168 to find (r) which equals 5.
Y-9=-2(x-8)
y-9=-2x+16
y=-2x+25
The slope is -2
For the first step you need to convert between feet in real life and feet in the cartoon drawing. 1/2 inch in cartoon is 3 feet in real life, so 1 foot in real life was 1/6 inch in cartoon. Her hair was 21 feet in real life, therefore it was 21/6, or 7/2 inches long in the cartoon. For the second step you need to explain what I just said, In your own words! Please do not simply copy down my solution.
Answer:
132 ft2
Step-by-step explanation:
The area of the rectangle is A=LxW
A= 9 x 11
Area of the rectangle is 99 ft2
To find the height of the triangle, subtract the width of the rectangle from the total height.
15-9= 6
The area of the triangle is A= 1/2 bh
A= 1/2 (11)(6)
Area of the triangle is 33 ft2
The total area is 99 + 33, which is 132 ft2
