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
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).

Exercise 4.2. Dining with Dad. Consider the events from Exercise 2.4, i.e., at a random meal during a parent weekend in the dining hall, a student notices the food chosen by her father. Let A, B, C' be the events that his meal include Artichokes, Broccoli, or Cauliflower. These events have the property that: P(A) = ) = 0.39;PfC) 0.44; P(An B) = 0.13; P(An C) = 0.12, P(B n C) = 0.13. 0.35; P(B Find the following conditional probabilities: P(B | C), P(C|B), P(A | B), P(B | A), P(A | C), P(C | A)
The conditional probabilities are as follows: P(B | C) = 0.295, P(C | B) = 0.371, P(A | B) = 0.371, P(B | A) = 0.333, P(A | C) = 0.273, and P(C | A) = 0.308. These probabilities represent the likelihood of one event occurring given that another event has already occurred.
To determine the conditional probabilities, we can use the formula:
P(X|Y) = P(X ∩ Y) / P(Y)
where X and Y are events.
1. P(B | C):
P(B | C) = P(B ∩ C) / P(C)
P(B ∩ C) = P(B n C) = 0.13
P(C) = 0.44
P(B | C) = 0.13 / 0.44 = 0.295
2. P(C | B):
P(C | B) = P(C ∩ B) / P(B)
P(C ∩ B) = P(B n C) = 0.13
P(B) = 0.35
P(C | B) = 0.13 / 0.35 = 0.371
3. P(A | B):
P(A | B) = P(A ∩ B) / P(B)
P(A ∩ B) = P(A n B) = 0.13
P(B) = 0.35
P(A | B) = 0.13 / 0.35 = 0.371
4. P(B | A):
P(B | A) = P(B ∩ A) / P(A)
P(B ∩ A) = P(A n B) = 0.13
P(A) = 0.39
P(B | A) = 0.13 / 0.39 = 0.333
5. P(A | C):
P(A | C) = P(A ∩ C) / P(C)
P(A ∩ C) = P(A n C) = 0.12
P(C) = 0.44
P(A | C) = 0.12 / 0.44 = 0.273
6. P(C | A):
P(C | A) = P(C ∩ A) / P(A)
P(C ∩ A) = P(A n C) = 0.12
P(A) = 0.39
P(C | A) = 0.12 / 0.39 = 0.308
Therefore, the conditional probabilities are:
P(B | C) = 0.295
P(C | B) = 0.371
P(A | B) = 0.371
P(B | A) = 0.333
P(A | C) = 0.273
P(C | A) = 0.308

Find the equation of the line that is perpendicular to the line 3z-y=-5 and passes through the point (7, -2)
Show work for the calculations without graphing, and choose the answer from below.
a.-x+3y=-1
b.x+3y=1
c.x-3y=-1
d.3x+y=3
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.

6) Make the following function linear using logarithms. \[ Q=f(L, K)=20 L^{2} K^{1} \]
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
what does the quadratic formula indicate about the graph of a quadratic function?
The Quadratic Formula indicates whether the graph intersects the ____ and where the ____
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.

Calculate the equilibrium price Demand: q=10−2p Supply: q=3p Is the price elasticity of demand inelastic, elastic, or unit elastic? Old Quantity demanded: 100 New Quantity Demanded: 50 Old Price: 100 New Price: 120 A
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.

find the residual if you know the actual number is 3 and the predicted value is 1.6
The residual if you know the actual number is 3 and the predicted value is 1.6l is 1.4.
The residual is a measure of the difference between the predicted value and the actual value. In this case, the actual number is 3, and the predicted value is 1.6. To find the residual, we subtract the predicted value from the actual value:
Residual = Actual Value - Predicted Value
= 3 - 1.6
= 1.4
Therefore, the residual in this case is 1.4.
The residual represents the error or the amount by which the predicted value differs from the actual value.
A positive residual indicates that the predicted value is lower than the actual value, while a negative residual indicates that the predicted value is higher than the actual value.
In this case, the positive residual of 1.4 indicates that the predicted value of 1.6 underestimates the actual value of 3 by 1.4.
