Answers
Answer:
4 feet = 48 inches
1 foot 6 inches = 18 inches
The hole needs to be 30 inches deeper.

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.

Find the circumradius of the triangle(side lengths 29, 29, 40)
(edit- is there something i am doing wrong or a reason none of my questions have been answered? because i have spent over 85 points asking questions around this difficulty, and have asked some of them a second time, and have waited in between 2and a half hours and an hour for all of them and no one has answered any
Answers
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
If you find this helpful, please give brainliest.
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

Answers
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

What is the median of the following set of numbers?

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 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.

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.

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.
