Answer:
z=30
Step-by-step explanation:
40-10=30
10+10+?=30
30-10-10=10
I'm sorry cuz I don't know how to explain it
Answer:
z = 10
Step-by-step explanation:
10 + 10 + z = 40 - 10
10 + 10 + z = 30
10 + 10 + 10 = 30
since 40 - 10 = 30, then Z has to equal 10 because 10 + 10 + z needs to be 30

if the third term is 20 and 7th is 1.25, find the 11th term
Answers
Answer:
the 11th term is 0.0000488 or 4.88*10^-5.
Step-by-step explanation:
a3 = 20, a7 = 1.25
a7 = a3r^7-3
1.25 = 20r^4
r^4 = 0.0625
r = 4th root of 0.0625
r = 0.5
a3 = a1r^3-1
20 = a1(20)^2
400a1 = 20
a1 = 0.05
a11 = 0.05(0.5)^11-1 = 0.0000488 or 4.88*10^-5
You are a civil engineer designing a bridge. The walkway needs to be made of wooden planks. You are able to use either Sitka spruce planks (which weigh 3 pounds each), basswood planks (which weigh 4 pounds each), or a combination of both. The total weight of the planks must be between 600 and 900 pounds in order to meet safety code. If Sitka spruce planks cost $3.25 each and basswood planks cost $3.75 each, how many of each plank should you use to minimize cost while still meeting building code?
Answers
The optimal solution to minimize cost while meeting the building code is to use 0 Sitka spruce planks and 150 basswood planks.
How to Minimize Cost Using Function Equations?To minimize the cost while meeting the building code, let's assume we use x Sitka spruce planks and y basswood planks.
We want to minimize the cost, so our objective function is the cost of the planks. The cost is given by:
Cost = 3.25x + 3.75y
We also have the constraint that the total weight of the planks must be between 600 and 900 pounds:
3x + 4y ≥ 600
3x + 4y ≤ 900
To solve this optimization problem, we can use linear programming. We'll use the Simplex method to find the optimal solution.
Let's rewrite the constraints in standard form:
-3x - 4y ≤ -600
3x + 4y ≤ 900
Now we have the following system of equations:
-3x - 4y ≤ -600
3x + 4y ≤ 900
The feasible region is a quadrilateral with vertices at (0, 150), (0, 225), (300, 150), and (225, 0).
To minimize the cost, we need to find the corner point of the feasible region that lies on the cost line, which is given by 3.25x + 3.75y.
Let's evaluate the cost at each corner point:
Cost at (0, 150) = 3.25(0) + 3.75(150) = 562.50
Cost at (0, 225) = 3.25(0) + 3.75(225) = 843.75
Cost at (300, 150) = 3.25(300) + 3.75(150) = 1500.00
Cost at (225, 0) = 3.25(225) + 3.75(0) = 731.25
From the evaluations, we can see that the minimum cost is achieved at (0, 150), which means we should use 0 Sitka spruce planks and 150 basswood planks.

A company has dump trucks that repeatedly go through three activities: loading, weighing, and travelling. Assume that there are eight trucks and that, at time 0, all eight are at the loaders. Weighing time per truck on the single scale is uniformly distributed between 1 and 9 minutes, and travel time per truck is exponentially distributed with mean 85 minutes. An unlimited queue is allowed before the loader(s) and before the scale. All truck can be travelling at the same time. Management desires to compare one fast loader against the two slower loaders currently being used. Each of the slow loaders can fill a truck in from 1 to 27 minutes, uniformly distributed. The new fast loader can fill a truck in from 1 to 19 minutes, uniformly distributed. The basis for comparison is mean system response time over a 40 hour time horizon, where a response time is defined as the duration of time from a truck arrival at the loader queue to that truck's departure from the scale. Perform statistically valid comparison of the two options simulated using common random numbers. a
Answers
To perform a statistically valid comparison of the two loader options, we can use simulation and common random numbers. We simulate the process over a 40-hour time horizon and compare the mean system response times for each loader option.
For the two slower loaders, we generate random numbers uniformly distributed between 1 and 27 minutes to represent the time taken to fill a truck. For the fast loader, we generate random numbers uniformly distributed between 1 and 19 minutes.
By simulating the process multiple times using the same set of random numbers (common random numbers), we can compare the mean system response times between the two loader options.
After running the simulation, we calculate the mean system response time for each loader option by averaging the response times of all trucks. We repeat the simulation multiple times (e.g., 100 or more) to obtain reliable estimates of the mean system response times.
Once we have the mean system response times for each loader option from multiple simulation runs, we can perform a statistical analysis to determine if there is a significant difference between the two options.
This analysis can be done using a suitable statistical test, such as a t-test or confidence interval analysis, depending on the distribution of the response time data and the assumptions made.
The statistical analysis will provide insights into whether the fast loader option significantly reduces the mean system response time compared to the slower loader options. A lower mean system response time would indicate better performance in terms of faster truck processing.

Cody did not understand the concepts of the “special cases” when factoring. Explain the concept of the perfect square binomial. Use an example to help explain to her how it is a special case and how to factor it using the special case rules.
Answers
A binomial expression of the form (a + b)² or (a - b)² is called a perfect square binomial.
This expression can be factored using the special case rules by rewriting it in the form
(a + b)(a + b) or (a - b)(a - b), respectively.
A perfect square binomial is a quadratic trinomial in which the first term is a perfect square and the second term is twice the product of the square root of the first term and the square root of the last term.
In the context of special cases, the perfect square binomial is a binomial that is formed by squaring a binomial.
This is a special case because it has a unique factorization, as we will see later.
An example of a perfect square binomial is (x + 4)².
This is because the first term, x², is a perfect square, and the second term, 8x, is twice the product of the square root of x² and the square root of 4, which is 2.
Hence, (x + 4)² can be factored using the special case rules as:
(x + 4)(x + 4),
which simplifies to
(x + 4)².
A perfect square binomial is a quadratic trinomial in which the first term is a perfect square and the second term is twice the product of the square root of the first term and the square root of the last term.
It is a special case because it has a unique factorization, which is given by the formula:
(a + b)² = a² + 2ab + b²
or
(a - b)² = a² - 2ab + b².

The base of each triangle is half the difference between the bases of the trapezoid:
(29 in -22 in)/2 = 7 in/2 = 3.5 in
The area of the triangle is given by the formula ...
A = 1/2bh
A = 1/2(3.5 in)(17 in) = 29.75 in² . . . triangle area
__
The area of the central rectangle is the product of its base and height.
A = bh = (22 in)(17 in) = 374 in² . . . rectangle area

The total area of the trapezoid is the sum of the areas of the two triangles and the area of the rectangle.
total area = 2(29.75 in²) + 374 in² = 433.5 in² . . . total trapezoid area

The value of the exterior angle (x) in a regular heptagon is approximately 51.43 degrees.
Given is a regular heptagon with one of the exterior angle be x we need to find the value of x
To find the value of the exterior angle of a regular heptagon, we can use the formula:
Exterior Angle = 360 degrees / Number of Sides
In this case, the heptagon has seven sides, so we can substitute the values into the formula:
Exterior Angle = 360 degrees / 7
Exterior Angle ≈ 51.43 degrees
Therefore, the value of the exterior angle (x) in a regular heptagon is approximately 51.43 degrees.
