Step-by-step explanation:

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).

Answer:

3x+2 + 6x+7 + 90 = 180

x=9

Step-by-step explanation:

Since JKL is a straight line, it equals 180

JKM + MKN + NKL = 180

3x+2 + 6x+7 + 90 = 180

Combine like terms

9x+99 = 180

Subtract 99 from each side

9x+99-99= 180-99

9x =81

Divide each side by 9

9x/9 = 81/9

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.

The given demand equation is q=10−2p, while the supply equation is q=3p. When the two equations are equated, we get;10-2p = 3pp = 2The equilibrium price is thus: q = 3(2) = 6Therefore, the equilibrium price is 6.

When the quantity demanded reduces from 100 to 50, and price increases from 100 to 120, we can calculate the price elasticity of demand to determine whether demand is elastic, inelastic, or unit elastic. Using the formula, the price elasticity of demand can be found as follows:

\frac{\frac{50+100}{2}}{\frac{120+100}{2}}=\frac{75}{110}. Using the midpoint formula, the price elasticity of demand is:0.68Since the price elasticity of demand is less than one, demand is inelastic.

In summary, when demand is inelastic, a change in price will have a smaller effect on quantity demanded. When demand is elastic, a change in price will have a greater effect on quantity demanded. Unit elastic demand is when the price elasticity of demand is exactly equal to 1.In this problem, the equilibrium price was determined to be 6. From this point, the price elasticity of demand was calculated to be 0.68, which is less than 1, implying that demand is inelastic. Therefore, a change in price from 100 to 120 will have a smaller effect on quantity demanded. In this case, the price elasticity of demand is greater than zero, which implies that demand is not perfectly inelastic.

The equilibrium price is 6.The price elasticity of demand is 0.68, indicating that demand is inelastic. When the price increases from 100 to 120 and quantity demanded falls from 100 to 50, the change in price will have a smaller effect on quantity demanded because demand is inelastic.

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

To find the equation of the line that is perpendicular to the line 3z - y = -5 and passes through the point (7, -2), we need to determine the slope of the given line and then find the negative reciprocal to get the slope of the perpendicular line. Using the point-slope form, we can then find the equation of the perpendicular line.

The given line 3z - y = -5 can be rewritten in slope-intercept form as y = 3z + 5. The slope of this line is 3. The slope of a line perpendicular to it will be the negative reciprocal of 3, which is -1/3.

Using the point-slope form with the point (7, -2), we have:

y - y₁ = m(x - x₁),

where (x₁, y₁) is the given point and m is the slope of the line.

Substituting the values, we get:

y - (-2) = (-1/3)(x - 7),

y + 2 = (-1/3)(x - 7).

To simplify and bring it to standard form, we can multiply both sides by 3:

3y + 6 = -x + 7,

x + 3y = 1.

Therefore, the equation of the line perpendicular to 3z - y = -5 and passing through the point (7, -2) is x + 3y = 1. Thus, option (b) is the correct answer.

Answer:

The linear function is given by z= log(20) +2y + x, where z=log(Q), y= log(L) and x=log(K).

Explanation:

we have given  Q=f(L, K)=20 L^{2} K^{1}

Taking logarithms on both sides,

                 log(Q) = log(20) + 2log(L) + log(K)

let z=log(Q), y= log(L) and x=log(K)

we obtain

                 z= log(20) +2y + x

The quadratic formula provides us with valuable information about the graph of a Quadratic function, such as its x-intercepts, vertex, axis of symmetry, and shape.

The quadratic formula can be used to determine the roots or solutions of a quadratic equation. It can also provide information about the graph of a quadratic function.

The quadratic formula provides us with two solutions for a quadratic equation. The solutions may be real or complex depending on the value of the discriminant.

The discriminant is the term under the radical in the quadratic formula and is represented by b² - 4ac. If the discriminant is positive, there are two real solutions, which means that the quadratic function intersects the x-axis in two distinct points.

If the discriminant is zero, there is one real solution and the quadratic function intersects the x-axis at one point. In this case, the quadratic function is said to have a double root or a repeated root.

If the discriminant is negative, there are no real solutions and the quadratic function does not intersect the x-axis. Instead, it has two complex solutions, which correspond to two imaginary x-intercepts.

In this case, the quadratic function opens up or down and has a minimum or maximum value, depending on the sign of the coefficient a. If a is positive, the graph opens up and has a minimum value.

If a is negative, the graph opens down and has a maximum value. The vertex of the parabola is located at the point where the axis of symmetry intersects the parabola.

The axis of symmetry is a vertical line that passes through the vertex and divides the parabola into two congruent halves. The quadratic formula can also be used to find the coordinates of the vertex of the parabola.

The x-coordinate of the vertex is given by -b/2a, which is the axis of symmetry. The y-coordinate of the vertex is obtained by substituting this value of x into the quadratic function.

Therefore, the quadratic formula provides us with valuable information about the graph of a quadratic function, such as its x-intercepts, vertex, axis of symmetry, and shape.

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.
