machine a, working alone at its constant rate, produces x pounds of peanut butter in 12 minutes. machine b, working alone at its constant rate, produces x pounds of peanut butter in 18 minutes. how many minutes will it take machines a and b, working simultaneously at their respective constant rates, to produce x pounds of peanut butter?
It will take 7.2 minutes for machines a and b, working simultaneously at their respective constant rates, to produce x pounds of peanut butter.
Rule #1: If a person can finish an entire job in k hours, then the person can complete 1/k of the job in one hour.
For example, if it takes Sue 5 hours to accomplish a task, she can complete 1/5 of the task in one hour. In other words, her hourly rate is one-fifth of the job's.Rule #2: If a person finishes a/b of a job in one hour, it will take b/a hours to finish the entire job.
For example, if Sam can finish 1/8 of the job in one hour, it will take him 8/1 hours to finish the job.Similarly, if Joe can finish 2/3 of the job in one hour, it will take him 3/2 hours to finish the job.Machine A finishes the job in 12 minutes.
Using Rule #1, machine A wraps up one-twelfth of the job in 1 minute.Machine B finishes the job in 18 minutes.
So, according to Rule #1, machine B finishes 1/18 of the job in 1 minute.When their efforts are combined, they can fulfill (1/12 + 1/18) of the job in 1 minute.
1/12 + 1/18 = 3/36 + 2/26 = 5/36So, when the machines work together, they can complete 5/36 of the job in 1 minute.Using Rule #2, the time required to complete the entire job = 36/5 minutes.
Therefore, 36/5 minutes or 7.2 minutes is the correct answer.

Evaluate the indefinite integral. (use c for the constant of integration.) x5 1 x12 dx
The evaluation of the given indefinite integral is (1/8)Tan⁻¹(x⁸) + C.
What is indefinite integral?A function that performs the antiderivative of another function is known as an indefinite integral. It can be represented visually as an integral symbol, a function, and finally a dx. A differentiable function F whose derivative is equal to the original function f is referred to as an antiderivative, inverse derivative, primitive function, primitive integral, or indefinite integral of a function f in calculus.So,
∫[x⁷ / (1 + x¹⁶)]dx = ∫[x⁷ / (1 + (x⁸)²]dxNow, u = x⁸. Then, du = 8x⁷dx. So, x⁷dx = (1/8)du.So, we obtain: (1/8)∫[du / (1 + u²)] = (1/8)Tan⁻¹u + C = (1/8)Tan⁻¹(x⁸) + CTherefore, the evaluation of the given indefinite integral is (1/8)Tan⁻¹(x⁸)+C.

distance between points -2,2 and 6,-4
Between the locations S(4,-3) and T(-2,2), there are 7.81 units between them.
The length of the line segment connecting two locations serves as a measure of the distance between them. Most importantly, the distance between two points is always positive and segments with the same length are known as congruent segments.
P(x1, y1) and Q(x2, y2) are two points, and the formula for their distance is provided by: d (P, Q) = (x2 - x1)2 + (y2 - y1) 2.
The points S(4,-3) and T are given.
Therefore, the distance (d) between S(4,-3) and T(-2,2) is as follows:
⇒ d (S, T) = √
² + (2 - (-3)) ².
⇒ d (S, T) = √ (-6)² + (5) ².
⇒ d (S, T) = √ 36+25

The stadium is to be renovated with a new seating capacity of 20790 seats.after the renovation what will be the percentage increase in the number of seats
Although part of your question is missing, you might be referring to this full question: The stadium has 15400 seats and it is to be renovated with a new seating capacity of 20790 seats. After renovation what will be the percentage increase in the number of seats?
The initial capacity of the stadium = 15400 seats
Planned new capacity = 20790 seats
Increment in the number of seats = 20790 - 15400 = 5390 seats
Percentage increase in the number of seats = (Increment in seats/Initial capacity of the stadium)*100
Therefore,
(5390/15400)*100 = 0.35*100 = 35%
So the percentage increase in the number of seats after renovation will be 35%

Given j(-8,-5) and l(6,-11) if k(r-4,2s) is the midpoint of jl which correctly gives the values of r and s?
The values of r and s is -1 and -4 respectively.
Given that:-
coordinates of j are (-8,-5)
coordinates of l are (6,-11)
coordinates of k are (r-4,2s)
Also, k is the mid-point of jl.
We have to find the values of r and s.
We know that, for (x,y) and (z,w), the mid-point is ((x+z)/2, (y+w)/2).
Here,
(x,y) = (-8.-5)
(z,w) = (6,-11)
(r-4,2s) = ((x+z)/2,(y+w)/2)
Hence,
(r-4,2s) = ((-8+6)/2,(-5-11)/2)
(r-4,2s) = (-1,-8)
Comparing the coordinates, we get:-
r - 4 = -1
r = -1+4 =3
2s = -8

What number will make this expression a perfect square trinomial? show your work. x² 8x __
The number must be added in the expression, x² - 8x, to make a perfect square trinomial is 16.
What is perfect square trinomial?Perfect square trinomials are algebraic representations that have three terms and are formed by multiplying a binomial by another binomial. A perfect square is a number formed by multiplying another number by itself.
The form is ax² + bx + c.
Where, a, b, and c are real numbers & a ≠ 0.
Now, as per the question; the expression is given as;
x² - 8x
The perfect square trinomial written in standard form as;
(x - a) = x² - 2ax + a²
In the given equation, enter c as the value to be added.
x² - 8x + c
By comparing it to the standard form
-8x = - 2ax ----->(1)
c = a2----->(2)
When we solve these equations for a and c, we get
-8x = - 2ax
a = -8/-2
a = 4
c = (4)² = 16
Thus,
(x - 4)² = x² - 8x + 16
As a result, the value that must be added is 16.

The equation that can be used to find the number of days is 32 - 3n = 11
How to determine the equation that can be used to find the number of days?The given parameters are
Initial amount = 32
Rate = 3 i.e. 3 children
Amount left = 11
Let the number of days be n
So, we have:
Initial amount - number of days * rate = amount left
This gives
32 - 3n = 11
Hence, the equation that can be used to find the number of days is 32 - 3n = 11
