A helicopter landing pad has a length of 80 ft and a width of 50 ft. A safety zone
of uniform width, which is not to be entered during landing, surrounds the landing
pad. The landing pad and safety zone together have a combined area of 10800 ft2,
what is the uniform width (safety zone) around the landing pad?
Answer:
uniform width around the landing pad = 9.41 feet
Step-by-step explanation:
Length of landing pad = 80 ft
width of landing pad = 50 ft
Length of safety zone = (80 + 2w)
width of safety zone = (50 + 2w)
Total area = 10800 [tex]ft^{2}[/tex]
Area of landing pad = length x width
= 80 x 50
= 4000 [tex]ft^{2}[/tex]
Area of landing pad = 4000 [tex]ft^{2}[/tex]
Thus,
area of safety zone = total area - area of landing pad
= 10800 - 4000
= 6800
area of safety zone = 6800 [tex]ft^{2}[/tex]
But,
area of safety zone = length x width
6800 = (80 + 2w) x (50 + 2w)
6800 = 4000 + 160w + 100w + 4[tex]w^{2}[/tex]
divide through by 4,
1700 = [tex]w^{2}[/tex] + 65w + 1000
⇒ [tex]w^{2}[/tex] + 65w + 1000 - 1700 = 0
[tex]w^{2}[/tex] + 65w -700 = 0
Applying the quadratic formula,
w = (-b ± [tex]\sqrt{b^{2} -4ac}[/tex]) ÷ 2a
a = 1, b= 65 and c = -700
w = (-65 ± [tex]\sqrt{(65)^{2}-(4*1*-700) }[/tex]) ÷ 2
= (-65 ± [tex]\sqrt{7025}[/tex]) ÷ 2
= (-65 ± 83.82)÷ 2
w = (-65 + 83.82) ÷ 2 OR (-65 - 83.82) ÷ 2
= 18.82 ÷ 2 OR -148.82 ÷ 2
= 9.41 OR -74.41
Thus, w = 9.41 ft.

graph each equation and tell whether it is linear. explain why or why not. graph y=3x+2
Answer:
This graph is linear, the degree of x does not exceed 1 and the graph forms a line.
Step-by-step explanation:
This is a question for geometry and its pretty hard.
Answer:
m EAD = 56
m EDA = 35
x = 4
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. This means that AE and EC are equal. To find x, simply set 2x + 3 = 11, and solve.
2x + 3 = 11
2x = 8
x = 4
Additionally, since the sides of a parallelogram are parallel, BC + AD are parallel, as are AB + DC. This make ECB + EAD and EBC + EDA opposite interior angles (have same measure). Thus, since we know ECB = 56 and EBC = 35, EAD also = 65 and EAD also = 35

can someone help me pls );
Answer:
Hope it helps you,
Step-by-step explanation:
As the figure can be split in to 3 geometric figure,
Rectangle , Triangle and Semi circle ,
So first find the area of these figures then add up them ,
Area of rectangle = Length * width
Length = 20m m and width = 14 mm
hence
Area of rectangle = 20*14 = 280 mm^2
Now ,
Are of Circle = [tex]\\ \pi *d^{2} /4[/tex]
Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]
Hence we have d= 20mm
Putt in semi circle formula we get,
Area of Semi Circle= (3.14)*400/8 = 157 mm^2
Now area of triangle = 1/2 * length*width
length =32-20 = 12 mm
width = 14 mm
putt in the formula we get ,
Area of triangle = 1/2*12*14 = 84 mm^2
Now add these 3 Areas to get total Area,
Total Area = 84+157+280 = 521 mm^2
find the surface area

the answer to your question is 7.5

The graph of a function is shown on the coordinate plane below. Identify the rate of change of the function.
Answer:
5/4
Step-by-step explanation:
Rise over run you go up 5 and left 4 so 5/4 is the ROC.
The rate of change of the function is given by the slope of the line m = -4/3
What is an Equation of a line?The equation of a line is y = mx + b where m is the slope which is the rise by run and b is the y-intercept
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
Given data ,
Let the rate of change of the function be m
The equation is represented as A
Now , the value of A is
Let the first point be P ( 0 , 4 )
Let the second point be Q ( 3 , 0 )
Slope m = -4/3
On simplifying the equation , we get
Slope m = -4/3
Now , the equation of line is
y - 4 = ( -4/3 ) ( x - 0 )
On simplifying the equation , we egt
y - 4 = ( -4/3 )x
y = ( -4/3 )x + 4
Hence , the equation of line is y = ( -4/3 )x + 4 and the rate of change of the function is m = -4/3
