A rectangular parcel of land has an area of 8,000 ft2. a diagonal between opposite corners is measured to be 10 ft longer than one side of the parcel. what are the dimensions of the land, correct to the nearest foot? ft (smaller value) by ft (larger value)
Answer:
Step-by-step explanation:
Let the area of the rectangle be Length × width
LW = 8000
If the diagonal is 10feer greater than one of its length then:
D = 10+L
Diagonal is represented using the Pythagoras theorem as shown:
D² = L²+W²
(10+L)²= L²+W²
100+20L +L² = L²+W²
From LW = 8000
W = 8000/L
100 + 20L = (8000/L)²
100 +20L = 64,000,000/L²
Cross multiply
100L² + 20L³ = 64,000,000
2L³+10L² = 6,400,000
L³+5L² = 3200000
L³+5L² -3200000 = 0
Answer:
55 ft by 146 ft
Step-by-step explanation:
Given the following :
Area of rectangle = 8000 ft^2
Area of rectangle = length(L) * width(W)
Let length of a side = x
Length of side 2 = 8000 / x
Diagonal = 10 feet longer than one side = (x + 10)
The diagonal is the hypotenus = (x + 10)²:
Hyp² = (8000/x)² + x²
(x + 10)² = (8000/x)² + x²
x² + 20x + 100 = 64,000,000 / x² + x²
20x + 100 = 64,000,000 / x²
(20x + 100) * x² = 64,000,000
20x³ + 100x² - 64,000,000 = 0
x³ + 5x² - 3200000 = 0
Using calculator
x = 145. 71 = 146 ft
8000 / x
8000/145.71
= 54.9 ft
= 55ft
55ft by 146 ft

Solve for a. Show your work: -2(a - 3) = 12
Answer: a = -3
Step-by-step explanation: First we distribute the -2 to a and -3 to get -2a+6=12, then subtract 6 on both sides, -2a=6, finally divide by -2 on each side to get a = -3.
Hope this helps!

how do solving two step problems with inequalities work?
equal sides of an isosceles triangle are given as 30 cm each if the perimeter of the triangle is 67 cm,find the third sides
pls help ...................
=======================================================
Explanation:
Start by graphing the system of equations
[tex]\begin{cases}x-y = 6\\2x+5y = -4\\ x = -1\end{cases}[/tex]
This is represented as the boundary lines. The first two equations produce solid boundary lines. The last equation makes a dashed boundary line. We use solid boundary lines whenever "or equal to" is involved with the inequality sign.
Note how 7 separate regions result from the intersecting lines. Check out the diagram below to see the different regions.
--------------------------
To graph [tex]x-y \le 6[/tex] which is the same as [tex]y \ge x-6[/tex], we will shade in regions 1, 2, 4 and 5. All of these regions are above the boundary line y = x-6
Ignore any other region (3,6, and 7) since they don't make the first inequality true.
Of regions 1, 4, 5 and 6, only regions 4 and 5 are below the boundary line 2x+5y = -4. So we cross off regions 1 and 6.
We're now down to just two regions: 4 and 5
We cross off region 5 because it is not to the right of the vertical line x = -1
All that's left is region 4. Any point in region 4 makes all of the three original inequalities true.
So the solution will only have region 4 shaded like choice D shows.

If x + 3 = 3x - 1 what is the value of x-1 ?
(hint: solve the first equation and Then substitute into the 2nd expression)
Answer: x=2.5, and x-1=1.5
Step-by-step explanation:
x + 3 = 3x - 1
(-x)= 3 = 2x - 1
(÷2) = 1.5 = x - 1
(+1)= 2.5 = x

Chris correctly measured the length of a line segment and his answer to the nearest centimeter. If the rounded measurement is 6cm, what would the most accurate statement about the actual measure of the line segment be?
Answer:
The most accurate statement is that the actual measure of the line segment is between 5.5 cm and 6.49 cm
Step-by-step explanation:
Here, given the measurement of the line segment rounded to the nearest cm as 6 cm, we want to give the most accurate statement about the actual measure
What we need here is the set of numbers which can be rounded to 6 cm
From 5.5 cm to 6.49 cm , all the measurements here can be rounded up to 6 cm
So the most accurate statement will be that the actual measure of the line segment is between 5.5 cm and 6.49 cm
The most accurate statement about the actual measure of the line segment be is between 5.56 to 6.49.
The measurement of the line segment rounded to the nearest cm as 6 cm, we need to give the most accurate statement.
What is a line segment?A line segment is a part of a line that connects two points which are distinct endpoints and contain every point on it.
From 5.56 cm to 6.49 cm, all the measurements here can be rounded up to 6 cm.
So, the most accurate statement will be the actual measure of the line segment between 5.56 cm and 6.49 cm.
