Answer:
It’s saying for every 1/4 inch, you have 3 feet. Let’s say I had an inch. That means I have 12 feet. Hope this helped!
Step-by-step explanation:
I only have an explanation. I don’t have the answer, but maybe I could help!
Perpendicular line always have slopes that are negative reciprocals of one another. Mathematically,
m1*m2=-1
So to be perpendicular to the line given, let's rearrange it to the point slope form of a line...
3y=6x ?3 (not sure what you wanted to type there)
anyway isolating y by dividing both side by three will leave 2x where 2 is the slope.
So for the other line to be perpendicular, m*2=-1, m=-1/2, now we have:
y=-x/2 +b, we can now you the point given to solve for b
4=-2/2 +b
4=-1+b
b=5 so
y=-x/2 +5 or more neatly
y=(10-x)/2

The one you can pick out that is true is D. The others you have to be careful with. C is a line and it has two arrowheads in the symbol above the two letters which makes it correct as well. A is not correctly marked, so it is not there the way it is marked. One would think ZX is a ray the way it is marked.
Answer: C and D
Answer:
x = 3.75
Step-by-step explanation:
So, lets start with what we know.
Line = 180 degrees
Triangle = 180 degrees, a + b + c = 180
So, we can form the equations,
17x - 1 + <CDB = 180
-17x + 1 -17x + 1
<CDB = 181 - 17x
and
84 +7x + 5 + <CDB = 180
89 + 7x + <CDB = 180
-89 -89 + 7x
<CDB = 91 + 7x
Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other
181 - 17x = 91 + 7x
-91 +17x -91 +17x
90 = 24x
90 / 24 = 24x / 24
3.75 = x
x = 3.75
There, you have it, x is 3.75

Answer: 112.5 square units</h3>
Work Shown:
A = area of the triangle
A = base*height/2
A = 9*7/2 = 63/2 = 31.5 ... see note1 below
B = area of rectangle
B = base*height
B = 9*3 = 27
C = area of parallelogram
C = base*height .... see note2 below
C = 9*6 = 54
If you're confused where I got the 6 from, check out the attached image below.
D = total area of the composite figure
D = A+B+C
D = 31.5 + 27 + 54
D = 112.5
-------------------------
note1: The vertical component of the triangle is 9 units because this is part of the rectangle. The rectangle has opposite sides that are the same length. The parallelogram's vertical sides are 9 units long as shown by the single tickmark.
note2: a rectangle is essentially a special case of a parallelogram. In other words, a rectangle is a parallelogram with 4 right angles. So this is why the formula "area = base*height" shows up identical for both rectangles and parallelograms. Keep in mind that the height is always perpendicular to the base. You will not use the segments marked with double tickmarks.
