Answer:
Step-by-step explanation:
First, put -4x+y=7 into y=mx+b format
move -4x to the other side (or add 4x on both sides)
y=4x+7
now, parallel lines have the same slopes, but not the same y intercepts.
So, you already know the slope of your new line
y=4x+b
now we need to find b (y intercept)
take the point (4,-3) and put it into the equation above
-3=4(4)+b
-3=16+b
move 16 to the other side (or subtract 16)
-19=b
therefore the new line will be y=4x-19

Here is a net made of right triangles and rectangles. All measurements are given in centimeters. Three rectangles in a row measuring 6 by 4, 6 by 5, and 6 by 3. The left rectangle is bordered on the top by a right triangle with side lengths 4, 3, and 5. The right rectangle is bordered on the bottom by a right triangle with side lengths 3, 4, and 5. What is the surface area of the polyhedron? Explain your reasoning.
Answer:
a. 84 cm² b. The area of the polyhedron is found by finding the sum of the areas of each individual shape.
Step-by-step explanation:
a. The area of the polyhedron is gotten by finding the area of each individual shape.
The area of the left rectangle with sides 6 by 4 is 6 cm × 4 cm = 24 cm²
The area of the middle rectangle with sides 6 by 5 is 6 cm × 5 cm = 30 cm²
The area of the right rectangle with sides 6 by 3 is 6 cm × 3 cm = 18 cm²
The area of the triangle on the left rectangle is found using heron's formula where area A = √[s(s -a)(s -b)(s -c) where s = (a + b + c)/2 and a, b and c are the sides of the rectangle.
Since the rectangle has sides 4, 3 and 5, a = 4, b = 3 and c = 5
So, s = (a + b + c)/2 = s = (4 + 3 + 5)/2 = 12/2 = 6
A = √[s(s -a)(s -b)(s -c)
= √[6(6 - 4)(6 - 3)(6 - 5)
= √[6(2)(3)(1)
= √36
= 6 cm²
The area of the triangle on the right rectangle is found using heron's formula where area A = √[s(s -a)(s -b)(s -c) where s = (a + b + c)/2 and a, b and c are the sides of the rectangle.
Since the rectangle has sides 3, 4 and 5, a = 3, b = 4 and c = 5
So, s = (a + b + c)/2 = s = (3 + 4 + 5)/2 = 12/2 = 6
A = √[s(s -a)(s -b)(s -c)]
= √[6(6 - 3)(6 - 4)(6 - 5)]
= √[6(3)(2)(1)
= √36
= 6 cm²
The surface area of the polyhedron is the sum of all the areas. So, A = 24 cm² + 30 cm² + 18 cm² + 6 cm² + 6 cm² = 84 cm²
b. Explain your reasoning
The area of the polyhedron is found by finding the sum of the areas of each individual shape.

(If an answer does not exist, enter lim
The value of f(-0.95) is 10.75, the value of f(-0.99) is 10.95, and the value of f(-0.999) is 10.995. The value of the limit of f(x) as x approaches -1 is -11, correct to six decimal places.
Given that the function is f(x) = 5x - 6.
The function is evaluated at different values of x such as
x = 0, -0.5, -0.9, -0.95, -0.99, -0.999, -2, -1.5, -1.1, -1.01, and -1.001.
Using the above values, the function is evaluated as follows:
f(0) = 5(0) - 6 = -6
f(-0.5) = 5(-0.5) - 6 = -8.5
f(-0.9) = 5(-0.9) - 6 = -10.5
f(-0.95) = 5(-0.95) - 6 = -10.75
f(-0.99) = 5(-0.99) - 6 = -10.95
f(-0.999) = 5(-0.999) - 6 = -10.995
f(-2) = 5(-2) - 6 = -16
f(-1.5) = 5(-1.5) - 6 = -13.5
f(-1.1) = 5(-1.1) - 6 = -11.5
f(-1.01) = 5(-1.01) - 6 = -11.05
f(-1.001) = 5(-1.001) - 6 = -11.005
The value of f(-0.95) is 10.75, the value of f(-0.99) is 10.95, and the value of f(-0.999) is 10.995.
Therefore, the value of the limit of f(x) as x approaches -1 is -11, correct to six decimal places.

You want to build a fence for your square backyard. The area of the fenced in yard is 500 ft. If you are using the wall of the house as one side of the fence, how many feet of fencing will you need if the base is x ft and the length is (x+5) ft?
To fence in a square backyard with an area of 500 ft², utilizing the wall of the house as one side, you would need a total of x + 3(x+5) feet of fencing.
Since the backyard is square, all four sides have equal lengths. Let's assume the length of each side is x. The area of a square can be calculated by multiplying the length of one side by itself, so we have x * x = x². Given that the area of the fenced-in yard is 500 ft², we can set up the equation x² = 500. Solving for x, we find that x ≈ 22.36 ft (rounded to two decimal places).
Now, we know the length of one side (x), and we need to find the total amount of fencing required. The three sides that do not utilize the wall of the house will each have a length of (x+5) ft, as mentioned in the question. Therefore, the total length of these three sides will be 3(x+5) ft.
Since the wall of the house is already serving as one side, we only need to add the length of the remaining three sides. Hence, the total amount of fencing required will be x + 3(x+5) = 22.36 + 3(22.36+5) ≈ 22.36 + 3(27.36) ≈ 22.36 + 82.08 ≈ 104.44 ft (rounded to two decimal places).

It takes 46 minutes for 10people to paint 3 walls. How many minutes does it take 4 people to paint 6 walls?
Answer:
10 people pain 3 walls in 46 minutes
So,
1 man can paint a wall in = 46/10 = 4.6 minutes
4 people can paint a wall in = 4.6 × 4 = 18.4 minutes.
Answer:
It takes 46 minutes for 10 people to paint 3 walls
It takes 92 minutes for 10 people to paint 6 walls (twice as long because you have twice as many walls)
you only have 4 people to paint the walls instead of 10 people
therefore it will take 2.5 times as long (10/4=2.5)
2.5*92=230 minutes
Step-by-step explanation:
This is actually a proportion question the one with the k.
So the question is about time so let's put a t first and a k on the other side.
t = k
Then let P = people and W = wall.
Let's take a look at the P first.
As the people increases, of course, the work would be faster making the time less. P go up, t go down. Meaning they're inversely proportional.
t = k/P
Next, the wall. When increasing the wall, you're increasing the work to do, and when the work increases, of course the time will also increase. Making them directly proportional.
t = (kW)/P
Using the first scenario:
46 = (k*3)/10
You will get the value of k = 460/3
Onto the second scenario:
t = kW/P; k = 460/3; W = 6; P = 4
t = ((460/3)*6)/4
t = 230 mins

Step-by-step explanation:
the volume of a tree stump can be modeled by considering it as a right cylinder. evelyn measures its circumference as 197 in and its volume as 92650 cubic inches. find the height of the stump in feet. round your answer to the nearest tenth if necessary.
The height of the tree stump is 2.48 feet.
To find the height of the tree stump, we can use the formula for the volume of a right cylinder: [tex]V = \pi r^2h[/tex], where V represents the volume, r represents the radius, and h represents the height.
Given that the circumference of the tree stump is measured as 197 inches, we can use the formula for the circumference of a circle: C = 2πr, where C represents the circumference.
From the given circumference, we can solve for the radius, r, by dividing the circumference by 2π: r = C / (2π).
Plugging in the given circumference of 197 inches, we have: r = 197 / (2π) ≈ 31.416 inches.
Now, we can substitute the known values of the volume and radius into the volume formula: 92650 = π(31.416)^2h.
To solve for the height, h, we divide both sides of the equation by π(31.416)^2: h = 92650 / (π(31.416)^2) ≈ 29.74 inches.
Since we want to convert the height from inches to feet, we divide the height by 12: h = 29.74 / 12 ≈ 2.48 feet.
Therefore, the height of the tree stump is approximately 2.48 feet.

Suppose the average yearly salary of an individual whose final degree is a masters is $49 thousand less than twice that of an individual whose final degree is a bachelors. Combined two people with each of the educational attainments earn $113 thousand
Answer:
Masters = 59,000
Bachelors = 54,000
Step-by-step explanation:
Given that:
individual whose final degree is a masters is $49 thousand less than twice that of an individual whose final degree is a bachelors
Let masters salary = m
Bachelors salary = b
m = 2b - 49000 - - - (1)
m + b = 113,000 - - - (2)
From (2)
m = 113,000 - b
Substitute m = 113,000 - b into (1)
113,000 - b = 2b - 49000
113000 + 49000 = 2b + b
162000 = 3b
b = 162000/3
b = $54000
Hence,
Masters salary :
m = 113,000 - b
m = 113,000 - 54,000
m = 59,000

field. 27. Prove in detail that Q(√3+√√7) = Q(√3, √√7). 28 Generalizing Exercise 27 show that if at /h +0. then Of Tat Octa Th) for all a and hin
To prove that Q(√3+√√7) is equal to Q(√3, √√7), we need to show that both sets contain the same elements. Therefore, x is an element of Q(√3+√√7).
To prove that Q(√3+√√7) = Q(√3, √√7), we need to demonstrate that both sets contain the same elements.
Let x be an arbitrary element in Q(√3+√√7). By definition, this means x can be expressed as:
x = a(√3+√√7), where a is a rational number.
Expanding the expression, we have:
x = a√3 + a√√7
Now, we can rewrite this expression as:
x = (b√3) + (c√√7), where b = a and c = a.
This shows that x can also be expressed as a linear combination of √3 and √√7. Therefore, x is an element of Q(√3, √√7).
Conversely, if x is an element of Q(√3, √√7), then it can be expressed as:
x = b√3 + c√√7, where b and c are rational numbers.
We can rewrite this expression as:
x = (a√3) + (a√√7), where a = b + c.
This shows that x can also be expressed as a linear combination of √3+√√7. Therefore, x is an element of Q(√3+√√7).
Since every element in Q(√3+√√7) is also in Q(√3, √√7), and vice versa, we can conclude that Q(√3+√√7) = Q(√3, √√7).
