An organization can purchase a bulk-mail permit for $190 per year. With the bulk-mail permit, each piece of mail, x, costs 27.6 cents to send. Without the permit, each piece of mail costs 44 cents to send. How many pieces of mail, x, would an organization need to send in a year to make it cheaper to use a bulk-mail permit
Answer:
1,159 pieces of mail
Step-by-step explanation:
From the information given, you can write an inequality that indicates that the price of sending each piece of mail without the permit is higher than the price of purchasing the bulk-mail permit and then, you can solve for x that is the number of pieces of mail:
0.44x>0.276x+190
0.44x-0.276x>190
0.164x>190
x>190/0.164
x>1,158.5
According to this, the organization needs to send 1,159 pieces of mail in a year to make it cheaper to use a bulk-mail permit.

give the perimeter of each figure as a simplified expression
Answer:
5k² - 7k + 6
Step-by-step explanation:
The perimeter of the figure given = the sum of all sides of the figure.
Perimeter = (k² - 9k + 23) + (k² + k) + (k² + k) + (2k² - 17)
Simply the expression as follows:
Perimeter = k² - 9k + 23 + k² + k + k² + k + 2k² - 17
Combine like terms
Perimeter = k² + k² + k² + 2k² - 9k + k + k + 23 - 17 (like terms are terms with the same degree)
Perimeter = 5k² - 7k + 6

-1/9 -1/2, 14/9,4/3 midpoints
Answer: (13/18, 1/6)
Step-by-step explanation: (-1/9, -1/2),(14/9, 4/3)
What you want to do is -1/9 + 14/9. Here our answer is 13/9. We then do 13/9 divided by 2 which in equation form is 13/9X1/2 which is 13/18. We want to solve the Y now. In equation form we do: 4/3 - 1/2 which equals 1/6 Therefore, the answer is (13/18, 1/6)

3x-2=2x+6 ayuda porfis
Answer:
x = 8
Step-by-step explanation:
3x - 2 = 2x + 6
3x - 2x - 2 = 2x - 2x + 6
x - 2 = 6
x - 2 + 2 = 6 + 2
x = 8
Answer:
x = 8
Step-by-step explanation:
move 2x to 3x and move -2 to 6
since its across the equal sign, it switches (postive to negative, negative to positive)
3x -2x = x
6 + 2 = 8

Write an equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power.
Answer:
(10)n =(9915)n
Step-by-step explanation:
An equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power could be as;
(10)n = 10(0.11515).
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Solving equations generally means finding the values of the variables used in it for which the considered equation is true.
We have to write an equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power.
Therefore, the equation could be as;
(10)n = 10(0.11515)
Hence, An equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by that power could be as;

Point B is the midpoint of point C and D. If CB is 14in, what is CD and BD?
Answer:
[tex]BD = 14\ in[/tex]
[tex]CD = 28\ in[/tex]
Step-by-step explanation:
Given
CB = 14in
B as midpoint
Required
Determine CD and BD
Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:
[tex]CB = BD[/tex]
[tex]CD = CB + BD[/tex]
Reorder the first equation
[tex]BD = CB[/tex]
Substitute 14 for CB
[tex]BD = 14\ in[/tex]
Taking the second equation into consideration
[tex]CD = CB + BD[/tex]

Answer:
f'(1)=150ln(1.5)
Step-by-step explanation:
I'm not sure why you would need a table since the limit definition of a derivative (from what I'm remembering) gives you the exact formula anyway... so hopefully this at least helps point you in the right direction.
My work is in the attachment but I do want to address the elephant on the blackboard real quick.
You'll see that I got to the point where I isolated the h's and just stated the limit equaled the natural log of something out of nowhere. This is because, as far as I know, the way to show that is true is through the use of limits going to infinity. And I'm assuming that you haven't even begun to talk about infinite limits yet, so I'm gonna ask you to just trust that that is true. (Also the proof is a little long and could be a question on it's own tbh. There are actually other methods to take this derivative but they involve knowing other derivatives and that kinda spoils a question of this caliber.)

Answer:
The strip of 16 by 14 inches.
Let x be the corner of the square cut
Then the box would have height as x, length 16-2x and width 14-2x

Solutions are
x= 2.483 and x = 7.517
Practically cutting more than 7 inches is not possible from 14 inches dimention

What are the different volume methods(cylindrical, shell etc) and what are their formulas rotating around both x and y axis?
Answer:
For revolution about the y-axis:
shell: dV = 2π·x·(f2(x) -f1(x))·dxdisk: dV = π·(f2(y)^2 -f1(y)^2)·dyFor revolution about the x-axis, swap x and y.
Step-by-step explanation:
The methods for computing the volume of revolution of a plane figure are ...
cylindrical shelldiskThe name of the method describes the shape of the differential of volume.
__
Cylindrical shell
For revolution about the y-axis, the differential of volume is a cylindrical shell of radius x, thickness dx, and height y2 -y1, where y2 = f2(x) and y1 = f1(x). (y2 > y1) Integration is over x.
dV = 2π·x·(f2(x) -f1(x))·dx
For revolution about the x-axis, the variables x and y are interchanged.
__
Disk
For revolution about the y-axis, the differential of volume is a donut or disk of inner radius f1(y) = x1 and outer radius f2(y) = x2 (x1 ≤ x2). The thickness is dy. Integration is over y.
dV = π·(f2(y)^2 -f1(y)^2)·dy
For revolution about the x-axis, the variables x and y are interchanged.
__
The preferred method is the one that gives simple integrable functions over a single range of integration. For some geometries, the integration range must be split, because the shape of the differential volume cannot be described by a simple rectangle whose length is the difference of functions of the integration variable.
When the differential of volume can be drawn either way, the choice of methods may be arbitrary. I usually choose the method that gives the simplest integrand.
_____
Additional comment
When the axis of revolution is something other than a coordinate axis, the radius of revolution becomes a different function than a simple x (or y). For example, if the axis of revolution is x=a, the radius of the cylindrical shell will be a-x (for x ≤ a) or x-a (for a ≤ x).
Here's an example of the use of the disk method.

A bookcase is to have 4 shelves including the top as pictured below.
The width is to be 16 feet less than 4 times the height. Find the width and the height if the carpenter expects to use 26 feet of lumber to make it.
Answer:
w= 3 feet
h= 5 feet
Step-by-step explanation:
H=height; W=width=2H-7ft
W=2H-7ft
2H+4W=22ft Substitute for W
2H+4(2H-7ft)=22ft
2H+8H-28ft=22ft Add 28 ft to each side.
10H=50ft
H=5 ft ANSWER 1: The bookshelf is 5 feet high.
W=2H-7ft=2(5ft)-7ft=10ft-7ft=3ft
ANSWER 2: the bookshelf is 3 feet wide.
CHECK:
2H+4W=22ft
2(5ft)+4(3ft)=22ft
10ft+12ft=22ft
22ft=22ft

Step-by-step explanation:
I think because you take the total and the amount of red you have
The probability of picking a red marble randomly from the bag will be equal to 0.44 .
It is given that there are total 9 marbles in a bag out of which 4 are red marbles.
We have to find the probability of picking a red marble randomly from the bag.
What do you mean by probability ?
Probability is the possibility or chance of an event to occur and is given by ratio of no. of favorable outcomes to total no. of outcomes.
As per the question ;
The total no. of outcomes (marbles) = 9
The no. of favorable outcomes (red marbles) = 4
We know that , probability is given by ;
Probability = No. of favorable outcomes / Total no. of outcomes
So ;
The probability of picking a red marble randomly from the bag will be equal to ;
Probability = 4 / 9
