Answer:
18.84 feet farther is it around the outer edge of the path than around the inner edge.
Step-by-step explanation:
Given:
A circular path 3 feet wide has an inner diameter of 350 feet.
Use 3.14 for π.
Now, to find how much farther is it around the outer edge of the path than around the inner edge.
Width of the circular path = 3 feet.
Inner diameter of circular path = 350 feet.
So, to get the inner radius we divide the inner diameter of circular path by width of circular path:
[tex]350\div 3[/tex]
[tex]=116.67\ feet.[/tex]
r = 116.67 feet.
Now,
Thus, the outer radius is:
[tex]116.67+3[/tex]
[tex]=119.67\ feet.[/tex]
R = 119.67 feet.
Now, we get the circumference of inner edge and outer edge:
Circumference of inner edge = 2πr.
[tex]Circumference\ of\ inner\ edge=2\times 3.14\times 116.67[/tex]
[tex]=732.69\ feet.[/tex]
Circumference of outer edge = 2πR.
[tex]Circumference\ of\ outer\ edge=2\times 3.14\times 119.67[/tex]
[tex]Circumference\ of\ outer\ edge=751.53\ feet.[/tex]
Now, to get how much farther is it around the outer edge of the path than around the inner edge:
Circumference of outer edge - circumference of inner edge.
[tex]751.53-732.69[/tex]
[tex]=18.84\ feet.[/tex]
Therefore, 18.84 feet farther is it around the outer edge of the path than around the inner edge.
The difference in distance around the outer edge of the path compared to the inner edge is 18.84 feet.
To find how much farther it is around the outer edge of the circular path compared to the inner edge, we need to calculate the circumferences of both the inner and outer edges and find the difference.
1. First, calculate the inner circumference using the inner diameter of 350 feet:
Inner Circumference = π × inner diameter = 3.14 × 350 = 1099 feet.
2. Next, calculate the outer diameter by adding the width of the path to each side of the inner diameter:
Outer Diameter = inner diameter + 2 × width of the path = 350 + 2 × 3 = 356 feet.
3. Then, calculate the outer circumference using the outer diameter:
Outer Circumference = π × outer diameter = 3.14 × 356 = 1117.84 feet.
4. Finally, find the difference between the outer and inner circumferences:
Difference = Outer Circumference - Inner Circumference = 1117.84 - 1099 = 18.84 feet.
Therefore, it is 18.84 feet farther around the outer edge of the path than around the inner edge.

Answer:
well i need to see the graph
Step-by-step explanation:
Both forms are equivalent, just different ways to write the same thing
==============================================
Explanation:
Use the slope formula first
The points we plug in are (x1,y1) = (-3,4) and (x2,y2) = (6,1)
m = (y2-y1)/(x2-x1)
m = (1-4)/(6-(-3))
m = (1-4)/(6+3)
m = (-3)/(9)
m = -1/3
The slope of the line is -1/3
Use one of the points, say the point (x,y) = (-3,4) and the slope we just found with y = mx+b. The goal is to solve for b
y = mx+b
4 = (-1/3)*(-3) + b
4 = 1 + b
4-1 = b
3 = b
b = 3
We have m = -1/3 as the slope and b = 3 as the y intercept
Therefore, the equation in slope intercept form is y = (-1/3)x + 3
In standard form, Ax+By = C, this is is equivalent to x+3y = 9 after we multiply both sides by 3, then add x to both sides.

If they average painting 3/4 of a room with 2/5 of a gallon of paint, then they can paint, on average ______ rooms per gallon.
Source:
Previous question that can be found at brainly
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Amount of paint needed to paint 3/4 of a room = 2/5 of a gallon
2. They can paint, on average how many rooms per gallon?
Let's use the Rule of Three Simple to answer this question, this way:
Paint Rooms
2/5 gallon 3/4
1 gallon x
x = Number of rooms on average painted with one gallon of paint
x * 2/5 = 3/4 * 1
x = 3/4 / 2/5
x = 3/4 * 5/2 = 15/8 = 1 7/8
West Painting can paint, on average, 1 7/8 rooms per gallon of paint
A photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41°. How tall is the lighthouse?
The height of lighthouse is 52.2 yards
Solution:
Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree
The diagram is attached below
Consider a right angled triangle ABC
AB is the height of the lighthouse
BC is the distance between the base of a lighthouse and Photographer
As per given, BC = 60 yards
Angle between the ground and the top of the lighthouse is 41 degree

by Thursday the Cutters and sewers in a clothing Factory had made 280 jackets. This is 87 1/2 % of the total number of jackets they were expected to make for the week. What is the total number of jackets the workers had to make that week?
Answer:
320
Step-by-step explanation:
87 1/2% (same as 87.5%) " of " the total jackets " is" 280
let j represent the total jackets
turn ur percent to a decimal....87.5% = 0.875
" of " means multiply , " is " means equals
0.875j = 280
j = 280 / 0.875
j = 320 <====== ur answer
Final answer:
The workers at the clothing factory were expected to make a total of 320 jackets for the week, as 280 jackets represented 87.5% of their weekly target.
Explanation:
To find the total number of jackets the workers were expected to make for the week, we'll set up a proportion where 87.5% corresponds to the 280 jackets they had made by Thursday. We know that 87.5% can also be expressed as the fraction 7/8. Therefore, if 7/8 of the total is 280 jackets, we need to divide 280 by 7 and then multiply by 8 to find the total number of jackets.
First, calculate the number of jackets corresponding to 1/8 of the total:
280 jackets
7 (parts) = 40 jackets
Next, multiply the value of 1/8 of the total by 8 to get the full 100%:
40 jackets
8 (parts) = 320 jackets
So, the workers were expected to make a total of 320 jackets for the week.

Passing through (1,-4) and (-2,5)
Answer:
y = -3x - 1Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two points (1, -4) and (-2, 5).
Substitute:
[tex]m=\dfrac{5-(-4)}{-2-1}=\dfrac{5+4}{-3}=\dfrac{9}{-3}=-3[/tex]
Substitute the value of a slope and the coordinates of the point (1, -4) to the equation of a line:
[tex]-4=-3(1)+b[/tex]
[tex]-4=-3+b[/tex] add 3 to both sides
[tex]-4+3=-3+3+b[/tex]

Rearrange the equation so n is the independent variable.
3m – 2n = 12
To make 'n' the independent variable, solve the equation 3m - 2n = 12 by isolating n to obtain n = (3/2)m - 6.
Explanation:To rearrange the equation 3m - 2n = 12 so that n is the independent variable, you'll want to solve for n. Here's how you do it step by step:
Start with the original equation: 3m - 2n = 12.Isolate the term containing n by moving the other terms to the opposite side of the equation: -2n = -3m + 12.Divide both sides of the equation by -2 to solve for n: n = (3/2)m - 6.This way, n is now expressed as a function of m, making n the independent variable in the equation.
The capacity of a backyard pool would most
likely be measured in which unit?
Answer:
I would use cubic meters :)
Step-by-step explanation:
Final answer:
The capacity of a backyard pool is commonly measured in gallons in the United States, or liters and kiloliters in countries using the metric system, due to the large volume of water pools can hold.
Explanation:
When considering the capacity of a backyard pool, we're dealing with a fairly large volume of water that needs to be measured. In the United States, the most common unit of measure for this purpose would be gallons, as it is a large unit for capacity suitable for measuring significant amounts of liquid like the volume of water in a swimming pool. Elsewhere, where the metric system is more common, one would likely use liters or kiloliters to quantify the capacity of a backyard pool.
For example, a typical backyard pool may contain about 15,000 gallons of water, which is significantly larger than quantities we would measure in smaller units such as milliliters or ounces. When discussing such large volumes, it's essential to use a unit of measure that appropriately represents the size of the container or space, hence gallons or liters are most suitable for the situation.
15. At a school for, 70% of the people are under 16 years old. One of the people rema
there are 21 teachers at the fair how many people are there at the far total
h. 125
Answer:
210 people are there at the fair
Step-by-step explanation:
Let the total number of people at the fair = X
People under 16 years old = 70% of X = 0.7 X
People remaining = Total number of people - Under 16 years
= X - 0.7X = 0.3X
The number of teachers = 1/3 of People remaining = 1/3 of 0.3X
Since there are 21 teachers
1/3 of 0.3X = 21
1/3 x 0.3X = 21
0.1X = 21
Divide both sides by the coefficient of X
0.1X/0.1 = 21/0.1
X = 210
That is 210 people are there at the fair

In the equation below, for what value of c does x = 4?
1 / (2x + 4) = 3x-c
Answer:
Option D.
Jenn's answer is not correct. She got it substituting [tex]c=4[/tex] into the equation and solving for "x".
Step-by-step explanation:
Given the following equation:
[tex]\frac{1}{2}(2x + 4) = 3x-c[/tex]
Since you need that [tex]x=4[/tex], you hace to substitute that value into the equation:
[tex]\frac{1}{2}(2(4) + 4) = 3(4)-c[/tex]
Now you need to solve for "c":
[tex]\frac{1}{2}(8 + 4) = 12-c\\\\\frac{12}{2}= 12-c\\\\6=12-c\\\\c+6=12\\\\c=12-6\\\\c=6[/tex]
Therefore for a a value of [tex]c=6[/tex], you get [tex]x=4[/tex]
Then, the you can identify that the correct answer is the one given in the Option D.
Jenn made a mistake, because she substituted [tex]c=4[/tex] into the equation and then solve for "x":
[tex]\frac{1}{2}(2x + 4) = 3x-(4)\\\\x+2=3x-4\\\\2+4=3x-x\\\\6=2x\\\\\frac{6}{2}=x\\\\x=3[/tex]
To determine the value of c when x equals 4 in the given equation, substitute x with 4 and solve for c. The resulting value of c is approximately 11.9167.
Explanation:To find the value of c for which x = 4 in the equation 1 / (2x + 4) = 3x - c, we start by substituting x with 4:
1 / (2×4 + 4) = 3×4 - c
1 / (8 + 4) = 12 - c
1 / 12 = 12 - c
Now we solve for c:
1 / 12 = 12 - c
c = 12 - 1 / 12
c = 12 - 0.0833
Finally, we find the value of c:
c = 11.9167
Therefore, for x = 4, the value of c is approximately 11.9167.

what is the equation of a line that passes through (1,3) and (4,9)
y = 2x + 1 is the equation of a line that passes through (1,3) and (4,9)
Solution:
Given that we have to write the equation of a line that passes through (1,3) and (4,9)
Let us first find the slope of line
The slope of line is given as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here the given points are (1,3) and (4,9)
[tex](x_1, y_1) = (1, 3)\\\\(x_2, y_2) = (4, 9)[/tex]
Substituting the values in formula, we get,
[tex]m = \frac{9-3}{4-1}\\\\m = \frac{6}{3} = 2[/tex]
Thus slope of line is 2
The equation of line in slope intercept form is given as:
y = mx + c -------- eqn 1
Where, "m" is the slope and "c" is the y - intercept
To find the y intercept, substitute (x, y) = (1, 3) and m = 2 in eqn 1
3 = 2(1) + c
c = 1
Thus the equation of line is:
Substitute c = 1 and m = 2 in eqn 1
y = 2x + 1
Thus equation of line is found
g(x) = -x2 + 12x - 32
In vertex form
Answer: g(x) = -(x - 6)² + 4
Step-by-step explanation:

g(x) = -(x² - 12x) - 32
g(x) = -(x² - 2 × x × 6 + 6² - 6²) - 32
g(x) = -[ (x - 6)² - 36 ] - 32
g(x) = -(x - 6)² + 36 - 32
g(x) = -(x - 6)² + 4

y=x^(2)-12x+40 in vertex form
Answer:
[tex]y=(x-6)^2+4[/tex]
Step-by-step explanation:
Vertex Form Of The Parabola
The equation of a parabola can be expressed in either standard or vertex form. The standard form is
[tex]y=ax^2+bx+c[/tex]
and the vertex form is
[tex]y=a(x-h)^2+k[/tex]
Where (h,k) it the vertex of the parabola
Transforming one into the other form is easily achieved by applying simple algebra .
Our function is
[tex]y=x^2-12x+40[/tex]
Completing squares, we have
[tex]y=x^2-12x+36+40-36[/tex]
Reducing
[tex]\boxed{y=(x-6)^2+4 }[/tex]
The vertex of the parabola is the point (6,4)
Final answer:
To convert the quadratic equation y = x^2 - 12x + 40 into vertex form, the completing the square method is employed, resulting in y = (x - 6)^2 + 4, showing the vertex at (6, 4).
Explanation:
Converting a Quadratic Equation to Vertex Form
The question asks how to convert the quadratic equation y = x2 - 12x + 40 into its vertex form. The vertex form of a quadratic equation is y = a(x - h)2 + k, where (h, k) is the vertex of the parabola. To convert the given quadratic equation into vertex form, we'll use completing the square method.
Start with the original equation: y = x2 - 12x + 40.Factor out the coefficient of x2, which is 1 in this case, so this step doesn't change the equation.Rewrite the equation focusing on the x-terms: y = (x2 - 12x) + 40.To complete the square, take half of the coefficient of x (which is -12/2 = -6), square it (-62 = 36), and add and subtract it inside the parenthesis: y = (x2 - 12x + 36) - 36 + 40.Simplify and rewrite: y = (x - 6)2 + 4.This shows the quadratic equation in vertex form with the vertex at (6, 4).

To write a formula that expresses y in terms of x, we can use the equation y = mx + b. Substitute the given values of x and y into the equation and solve for m and b. The final formula is y = 1.67x + 1.25.
Explanation:To write a formula that expresses y in terms of x, we need to determine the relationship between y and x. In this case, we know that when x = 1.5, y = 2.5. So we can start with the equation y = mx + b, where m is the slope and b is the y-intercept.
Using the given values, we can substitute x = 1.5 and y = 2.5 into the equation y = mx + b: 2.5 = 1.5m + b. Now we can solve for m and b by using the given values and algebraic manipulation.
By rearranging the equation and substituting the values of x and y, we can determine the formula that expresses y in terms of x. The final formula will be y = 1.67x + 1.25.
