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.
Answers
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
Answers
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.

Rhiannon went to the store and bought two sweatshirts. She spent $72. What was the price of each sweatshirt?
Would you write an inequality or an equation?
Answers
To solve this problem, we can use the equation:
2x = 72
Where x represents the price of one sweatshirt. We multiply by 2 because Rhiannon bought two sweatshirts.
Simplifying the equation we get:
x = 36
Therefore, each sweatshirt costs $36.
We used an equation to solve this problem.

please help math sucks
Answers
Answer:
Last option: {-5, -1, 2, 11}
Step-by-step explanation:
Required inequality is x > -6
That means every item in the set of values indicated should be > - 6
We should eliminate answers with - 6 since -6 is not greater than -6 it is ≥ -6
That leaves 2 and 4
When comparing negative numbers, a negative number which has absolute value greater than the absolute value of another number will always be less than the other number
For example, -11 has absolute value 11
- 6 has absolute value 6
11 > 6
So - 11 < -6
All the values in option 2 are therefore < - 6
Therefore last option is the correct one
-5 > -6, -1 > -6 and positive numbers are always greater than negative numbers

w – 43 ≥ 47
Please add work to this
Answers
Answer: W ≥ 90
Step-by-step explanation:
To solve the inequality W - 43 ≥ 47, we need to isolate the variable W on one side of the inequality.
W - 43 ≥ 47
Add 43 to both sides of the inequality:
W - 43 + 43 ≥ 47 + 43
Simplify:
W ≥ 90
Therefore, the solution to the inequality is W ≥ 90.
Explanation:
We want W (or anything we are trying to find a value for) to be by itself on one side of the equation. Since -43 and 47 are like terms and can be combined, we want to bring them together. To do this, we want to cancel out -43 because W and -43 are not like terms. To cancel out -43, we must add +43, because -43+43=0. Whatever we do to one side of an equation we must to do another, so we add +43 on the other side of the equation as well, making it W > 47 + 43, which equals W > 90.

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
Answers
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.

What is the value of m in the equation?
m+3/4=12?
_____-__
Answers
Answer:
To solve for the value of m in the equation:
m + 3/4 = 12
We need to isolate the variable m on one side of the equation. We can do this by subtracting 3/4 from both sides of the equation:
m + 3/4 - 3/4 = 12 - 3/4
Simplifying the left side of the equation by canceling out the 3/4 terms:
m = 12 - 3/4
To combine the two terms on the right side of the equation, we need to find a common denominator. Multiplying 12 by 4/4 gives us:
m = (48/4) - 3/4
Combining the terms on the right side of the equation:
m = 45/4
Therefore, the value of m in the equation is 45/4.
Answer:
m= 45/4

What is the equation of this function?
Answers
We can use the point-slope form of a linear equation to find the equation of the function:
y - y1 = m(x - x1)
where m is the slope of the line, and (x1, y1) is a point on the line.
First, we can find the slope of the line by using the two given points:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) = (4, 24) and (x2, y2) = (6, 30):
m = (30 - 24) / (6 - 4) = 3
Now we can use one of the two given points, say (4, 24), and the slope m = 3 to write the equation of the line in point-slope form:
y - y1 = m(x - x1)
y - 24 = 3(x - 4)
Simplifying this equation, we get:
y - 24 = 3x - 12
y = 3x + 12
Therefore, the equation of the linear function is y = 3x + 12.
