A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the park are 12 inches wide by 20 inches long. A rectangular area of the park for swing sets is 0.5 inch wide by 2 inches long on the scale drawing.
What is the actual length of the swing set area of the park?
Enter your answer in the box.
The actual length of the swing set area of the park is ______ feet.
Answer: The dimensions of the park on the scale drawing is 12 inches and 20 inches.
Dimension
Actual dimensions:
Park = 600 feet by 1000 feet
Swing set = 25 feet by 100 feet
Swing set on the scale drawing= 0.5 inch by 2 inches
Hence:
Dimension of park on drawing:
Width = 600×1/50
Width = 12inches
Length = 1000×1/50
Length= 20inches
In conclusion the dimensions of the park on the scale drawing are 12 inches and 20 inches.

If x=-5 find the value of 5x^2-2x+5
When x is equal to -5, the value of the expression 5x^2 - 2x + 5 is 140, by substitution method.
To assess an articulation for a given worth of a variable, we can substitute the worth into the articulation and improve on it. For this situation, we are given the articulation 5x^2 - 2x + 5 and we are told to assess it when x is equivalent to - 5. To do this, we substitute - 5 for x in the articulation to get 5(- 5)^2 - 2(- 5) + 5. We then, at that point, improve on this articulation by first assessing - 5 squared, which is 25. We then increase 5 by 25 to get 125, and add 10 and 5 to find the last solution of 140. In this manner, when x is equivalent to - 5, the worth of the articulation 5x^2 - 2x + 5 is 140.

Answer: 140
Step-by-step explanation:
given value
x= -5
we need to solve this equation by putting that value of
x =-5 in equation , 5x²- 2x + 5
now , 5 (-5)² - 2(-5) +5
125 + 10 + 5
= 140

How can the area of this triangle be determined by forming a rectangle?
Select from the drop-down menus to correctly complete the statements.
Copy and rotate the triangle and place it next to the existing triangle to form a rectangle. The length of the rectangle is
Choose...
units. The width of the rectangle is
Choose...
units. The area of the rectangle is
Choose...
square units.
The area of the triangle is half the area of the rectangle, so the area of the triangle is
Choose...
square units.
Answer:
Length of the rectangle = 5 units
Width of rectangle = 4 units
Area of rectangle = 20 units
Area of triangle = 10 units
Step-by-step explanation:
Since I don't know the answer choices, I am assuming the base of the triangle as the length and the height as the width. Check your answer choices and switch 4 and 5 if it is the other way around
Using the graph
The rectangle formed by rotating the triangle and placing it along the original rectangle will have a length(base)
= length of the base of the triangle
= 5 units
The width of the rectangle will be the same as the height of the rectangle = 4 units
The area = length x width = 5 x 4 = 20 units
Area of triangle = half area of rectangle = 20/2 = 10 units
Which is a way to find the equation of a line that best fits this data?
A way to find the equation of a line that best fits this data include the following: A. Use the coordinates of points B and D to find the slope and then the equation of the line that passes through them.
What are the characteristics of a line of best fit?In Mathematics, there are different characteristics that are used for determining the line of best fit on a scatter plot and these include the following:
The line should be very close to the data points as much as possible.The number of data points that are above the line should be equal to the number of data points that are below the line.By critically observing the scatter plot using the aforementioned characteristics, we can reasonably infer and logically deduce that data points B and D represent the line of best fit because they are in a linear pattern.

Answer: "B. -5"
Step-by-step explanation:
STEP 1: Plug -5 into the equation where "X" currently is; 10 (-5) - 5 = -55
STEP 2: Multiply 10 (-5) [-50].
STEP 3: Update the equation to reflect Step 2; -50 - 5 = -55
STEP 4: Subtract 5 from -50 [-55].
STEP 5: Update the equation to reflect Step 4; -55 = -55
It is true that -55 = -55, so, therefore, the answer is "B. -5."

What is the median of the following set of numbers?
121, 347, 45, 21, 300, 614, 312, 333, 421
a.300
b.312
c.322.5
d.306
Answer:
312
Step-by-step explanation:
To find the median of a set of numbers, we need to arrange them in order from smallest to largest and then find the middle number. If there are an odd number of values, the median is the middle number. If there are an even number of values, the median is the average of the two middle numbers.
Arranging the given numbers in order from smallest to largest, we get:
21, 45, 121, 300, 312, 333, 347, 421, 614
There are nine numbers in the set, which is an odd number, so the median is the middle number. The middle number is the fifth number in the ordered list, which is:
Median = 312
Therefore, the median of the given set of numbers is 312.

20:60
12:36
2:6
there r other ways you can do it tho :)
Answer: 20:60, 12:36, 2:6.
Step-by-step explanation: 4:12 = 1:3. The ratio 4:12 is equal to 1:3. which means that the second number (sn) is 3 times the first number (fn). sn = 3 * fn. The first equation: sn = 3 * 20. 3 * 20 is 60, so the second number would be 60. The second equation: 36 = 3 * fn. Divide each side by three, so the equation reads 12 = fn. The last equation: 6 = 3 * fn. Divide each side by three, so the equation reads 2 = fn.

Find the circumradius of the triangle(side lengths 29, 29, 40)

Answer:
See explanation below
Step-by-step explanation:
△ABC is isosceles right triangle because AB = BC = 29. Therefore the height of △ABC (which we can call AD) will bisect base AC at 90 degrees.
We can calculate the height of AD using Pythagorean theorem with BC is the hypotenuse (which is 29), and the side DC (equals 1/2 AC = 40/2 = 20)
=> BC^2 = BD^2 + DC^2
=> BD^2 = BC^2 - DC^2 = 29^2 - 20^2 = 841 - 400 = 441
=> BC = 21
so area of △ABC = hb/2 = (21 x 20)/2 = 210
To find the circumradius, we need to use formula A = abc/4R
=> R = abc/4A
R = (29)(29)(40)/(4 x 210) = (29 x 29 x 10)/210 = 40.05

20 units is the circumradius of the triangle which has side lengths 29, 29, 40.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To find the circumradius of a triangle with side lengths a, b, and c, use the formula:
circumradius = abc / 4Δ
where Δ is the area of the triangle.
To find the area of the triangle, use Heron's formula:
s = (a + b + c) / 2
Δ = √(s(s-a)(s-b)(s-c))
where s is the semiperimeter of the triangle.
In this case, the side lengths of the triangle are 29, 29, and 40. The semiperimeter is:
s = (29 + 29 + 40) / 2 = 49
Using Heron's formula, the area of the triangle is:
Δ = √(49(49-29)(49-29)(49-40))
= √(49×20×20×9)
=√176400
= 420
Now, using the formula for the circumradius, we have:
circumradius = abc / 4Δ
= (29×29×40) / (4×420)
=20 units
Therefore, the circumradius of the triangle is 20 units
