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?
Answers
Step-by-step explanation:
Let w be the uniform width of the safety zone.
We have combined area = 10,800ft².
=> Combined area = Length * Width
= (80 + 2w)(50 + 2w)ft².
Therefore (80 + 2w)(50 + 2w) = 10,800.
=> 4,000 + 260w + 4w² = 10,800
=> 4w² + 260w - 6,800 = 0
=> w² + 65w - 1,700 = 0
=> (w - 20)(w + 85) = 0
=> w = 20 or w = -85
(w = -85 is rejected as width must be positive)
Hence the uniform width is 20ft.

Find the geometric mean of 24 and 45.
Answers
The geometric mean of 24 and 45 is equal to 32.86.
Given the following data:
Numbers = 24 and 45.What is geometric mean?Geometric mean is an average value that is used to indicate the central tendency of a data set containing a group of numbers, especially by determining the product of their values.
Mathematically, geometric mean is given by this formula:
[tex]G=\sqrt[n]{x_1x_2...x_n}[/tex]
Substituting the given parameters into the formula, we have;
[tex]G = \sqrt[2]{24 \times 45} \\\\G = \sqrt{1080}[/tex]
G = 32.86.

Answers
Answer:
-1.5 = -3/2
-4/5 > -5/4
-3/5 = -6/10
-2/3 < 1/3
Step-by-step explanation:
If you convert -3/2 into a decimal, it equals -1.5
-5/4 is an improper fraction which makes it greater than one, but since it is negative, it is further away from zero making it less than -4/5
-3/5 is the simplified form of -6/10. 3x2= 6 and 5x2=10
1/3 is positive making it greater than any negative

A gardener has a rectangular flowerbed. The length of the flowerbed is 5 feet more than the width. The perimeter of the flowerbed is 70 feet. Which equation can be used to find the width w in feet?
A. 2w + 5 = 70
B. 2(w+ 5) = 70
C. 2(2w+5) = 70
D. w(w+5) = 70
Answers
So widths plus the 5 feet, then multiple by 2 (the two widths of the rectangle) equal the number of the perimeter of the flowerbed (70 feet).
2(w+5)=70
The equation for the perimeter is 2(2w + 5) = 70, to calculate the width.
What is a rectangle?The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.
Given the perimeter of a rectangular flower bed = 70 feet
and the length of the flowerbed is 5 feet more than the width,
let width be w
length = w + 5
perimeter is given by = P = 2(l + b)
P = 2(w + w + 5)
P = 2(2w + 5)
Hence option C is correct to find the width of the rectangular flowerbed.
