Answer:
beginning inventory is $245000
Step-by-step explanation:
Given data
ending inventory = $150,000
purchased additional inventory = $375,000
goods sold = $470,000
to find out
beginning inventory
solution
according to question beginning inventory is calculated by this formula i.e.
beginning inventory = ( cost of goods sold + ending inventory ) - amount of inventory purchase .....................1
now put all value cost of goods sold, ending inventory and amount of inventory purchase in equation 1 and we get beginning inventory
beginning inventory = ( cost of goods sold + ending inventory ) - amount of inventory purchase
beginning inventory = ( 470000 + 150000 ) - 375000
beginning inventory = 245000
so beginning inventory is $245000
What are the discontinuity and zero of the function f(x) = x^2+5x+4/x+4
Answer:
The zeros of our function f is at x=-1.
The discontinuity is at x=-4.
These are correct if the function is [tex]f(x)=\frac{x^2+5x+4}{x+4}[/tex] .
Please let know if I did not interpret your function correctly.
Step-by-step explanation:
I imagine you mean [tex]f(x)=\frac{x^2+5x+4}{x+4}[/tex] but please correct me if I'm wrong.
The zero's of a rational expression occur from it's numerator.
That is, in a fraction, the only thing that makes that fraction 0 is it's numerator.
So we need to solve [tex]x^2+5x+4=0[/tex] for x.
The cool thing is this one is not bad to factor since the coefficient of x^2 is 1. When the coefficient of x^2 is 1 and you have a quadratic, all you have to do is ask yourself what multiplies to be c and adds to be b.
[tex]x^2+5x+4[/tex] comparing to [tex]ax^2+bx+c[/tex] gives you [tex]a=1,b=5,c=4[/tex].
So we are looking for two numbers that multiply to be c and add to be b.
We are looking for two numbers that multiply to be 4 and add to be 5.
Those numbers are 1 and 4 since 1(4)=4 and 1+4=5.
The factored form of [tex]x^2+5x+4[/tex] is [tex](x+1)(x+4)[/tex].
So [tex]x^2+5x+4=0[/tex] becomes [tex](x+1)(x+4)=0[/tex].
If you have a product equals 0 then at least one of the factors is 0.
So we need to solve x+1=0 and x+4=0.
x+1=0 when x=-1 (subtracted 1 on both sides to get this).
x+4=0 when x=-4 (subtracted 4 on both sides to get this).
The zeros of our function f is at x=-1 and x=-4.
Now to find where it is discontinuous. We have to think 'oh this is a fraction and I can't divide by 0 but when is my denominator 0'. If the value for the variable is not obvious to you when the denominator is 0, just solve x+4=0.
x+4=0 when x=-4 (subtracted 4 on both sides).
So we have a contradiction at one of the zeros so x=-4 can't be a zero.
The discontinuity is at x=-4.
Answer:
This function is discontinuous at x = 4, and has a zero at x = -1.
Step-by-step explanation:
If x = -4, the denominator will be zero and thus the function will be undefined. Thus, the discontinuity is at x = -4.
To find the zero(s): Set the numerator = to 0, obtaining
x^2+5x+4 = 0. Factoring this, we get (x + 4)(x + 1) = 0. Thus, we have a zero at x = -1.
Notice that f(x) can be rewritten as
x^2 + 5x + 4 (x+4)(x+1)
f(x) = -------------------- = ---------------- = x + 1 for all x other than x = -4.
x + 4 (x+4)
This function is discontinuous at x = 4, and has a zero at x = -1.
Find the volume and surface area of the composite figure. Give four answer in terms of π.
Answer:
V = 99π in³; S = 81π in²
Step-by-step explanation:
Volume is that of a hemisphere of radius 3 in together with that of a cylinder of radius 3 in and height 9 in.
V = (2/3)πr³ +πr²h = (πr²)(2/3r +h)
= 9π(2 +9) = 99π . . . . in³
__
The area is that of a hemisphere, the side of the cylinder, and the circular bottom of the cylinder.
S = 2πr² +2πrh +πr² = πr(2r +2h +r)
S = 3π(6+18 +3) = 81π . . . . in²

Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets $25. The venue has the capacity to hold 400 people. The graph represents the number of tickets Anna needs to sell to offset her upfront costs and raise at least $5,000 for her school:
What is the minimum number of at-the-door tickets she needs to sell to make her goal?
A,333
B.334
C.66
D.67
Answer: The answer would be 333
Step-by-step explanation: Hope this was helpful
To make at least $5,000, Anna must sell a minimum of 200 at-the-door tickets priced at $25 each. This is the minimum required, but the venue's capacity allows for selling up to 400 tickets to potentially exceed the fundraising goal.
Explanation:The question asks us to calculate the minimum number of at-the-door tickets Anna needs to sell to meet the fundraiser target of at least $5,000, given the constraints of the venue capacity and the ticket prices. This can be solved by first identifying the total amount needed to be raised and then calculating the number of at-the-door tickets needed if no pre-sale tickets are sold.
Since at-the-door tickets sell for $25 each, we divide the total amount Anna wants to raise ($5,000) by the price of each at-the-door ticket:
$5,000 ÷ $25 = 200 tickets
This means Anna will have to sell at least 200 at-the-door tickets to raise $5,000. However, the venue limits the capacity to 400 people, and it is not specified how many pre-sale tickets are sold. To ensure reaching the target, assuming no pre-sale tickets are sold, Anna should aim to sell all 400 tickets at the door. Selling any fewer at the door would require pre-sale tickets to make up the difference to reach the $5,000 target.
Therefore, the minimum number of at-the-door tickets Anna needs to sell to reach the $5,000 goal is 200, although to fully utilize the venue's capacity and potentially exceed the target, she can sell up to 400 tickets at the door.

What is the next number in the sequence? 9….3….1….1/3…
The pattern in the sequence 9, 3, 1, 1/3 involves each number being a third of the previous number. Following this rule, the next number after 1/3, obtained by dividing by 3, is 1/9.
Explanation:To determine the next number in the sequence 9, 3, 1, 1/3, we need to identify the pattern or rule that is being followed. Observing the sequence, each subsequent number appears to be a third of the previous number. The first number is 9, and dividing by 3 gives us 3. Dividing the second number, 3, by 3 gives us 1.
Similarly, dividing the third number, 1, by 3 gives us 1/3. Following this logic, to find the next number in the sequence, we divide 1/3 by 3.
Using the arithmetic of division with fractions, we have (1/3) ÷ 3 = (1/3) ÷ (3/1) = 1/9. Therefore, the next number in the sequence is 1/9. We can assume that the rule being applied in this sequence is to divide each number by 3 to find the next number, which aligns with the mathematical pattern identification techniques commonly used.
The next number in the sequence is 1/9.
To find the next number in the sequence 9, 3, 1, 1/3, we need to identify the pattern. This sequence is a geometric sequence where each term is obtained by multiplying the previous term by a common ratio.
Step-by-step:
Start with 9.Multiply it by the common ratio to get the next term.9× (1/3) = 33 ×(1/3) = 11 ×(1/3) = 1/3To find the next term, we continue this pattern:
1/3× (1/3) = 1/9

Browning Labs is testing a new growth inhibitor for a certain type of bacteria. The bacteria naturally grows exponentially each hour at a rate of 6.2%. The researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. The sample currently contains 100 bacteria.The container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. However, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. They would like to determine the possible number of bacteria in the container over time.Create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
Hey! I just answered this on plato. the answer is that it includes negative factors, which makes not all solutions viable.
Answer:
Look at the attachment
Step-by-step explanation:
First we need to find out the equations that will represent each inequality:
For the bacteria:
This is an exponential growth equation, the formula is simple:
y≤[tex]n*(1+r)^{x}[/tex] where n is the starting point of the sample, r is the rate and x is the variable dependent on time so:
y≤[tex]100*(1+0.062)^{x}[/tex]
y≤[tex]100*(1.062)^{x}[/tex]
For the container:
This is a line equation, following the formula:
y<mx+b where m is the slope or growing rate (100 more per hour), and b is the starting point (300 bacteria)
y< 100x+300
The graph will be like is showed in the attachment, and the solution is the intersecting area to the right of both functions, since they are trying to find out if the inhibitor works, the rate of growth will be equal or smaller than 6.2% thus closing in to 100 bacterias as a constant in time if it works.

Parameter because the value is a numerical measurement describing a characteristic of a population.
Answer:
b. Statistic
Step-by-step explanation:
b. Statistic because the value is a numerical measurement describing a characteristic of a sample.
Answer:
Option b
Step-by-step explanation:
Given that a sample of employees is selected and it is found that 55 % own a vehicle.
Before we answer the questions let us understand the difference between a parameter and a statistic.
Parameters are numbers that summarizes the data of a population. But statistics are numbers that summarizes the data of a sample.
Sample is a subset of population i.e. a small portion of the whole population is sample.
Here 55% is the proportion of the sample of employees. Since this is a number summarizing the data about a sample this is called statistic.
b. Statistic because the value is a numerical measurement describing a characteristic of a sample.
In your drawer you have 10 white socks, 6 black socks, 4 brown socks and 2 blue socks. Your roommate is still asleep, and you cannot turn the light on while you get dressed. You reach in blindly and grab two socks. What is the probability of pulling out a matching pair of black socks?
Answer: Required probability is,
[tex]\frac{36}{231}[/tex]
Step-by-step explanation:
Given,
White socks = 10,
Black socks = 6,
Brown socks = 4,
Blue socks = 2,
Total socks = 10 + 6 + 4 + 2 = 22,
Thus, the total ways of choosing any 2 socks = [tex]^22C_2[/tex],
Now, the ways of choosing a black socks = [tex]^6C_1[/tex]
Thus, ways of choosing a pair of black socks = [tex]^6C_1\times ^6C_1[/tex]
Hence, the probability of pulling out a matching pair of black socks
= [tex]\frac{^6C_1\times ^6C_1}{^{22}c_2}[/tex]
= [tex]\frac{36}{231}[/tex]
Assume that the wooden triangle shown is a right triangle.
a. Write an equation using the Pythagorean Theorem and the measurements provided in the diagram.
Hint: (leg 1)2 + (leg 2)2 = (hypotenuse)2
b. Transform each side of the equation to determine if it is an identity.
a.
a^2 + b^2 = c^2
The legs are a and b. c is the hypotenuse.
Let a = 6x + 9y; b = 8x + 12y; c = 10x + 15y
The equation is:
(6x + 9y)^2 + (8x + 12y)^2 = (10x + 15y)^2
b.
Now we square each binomial and combine like terms on each side.
36x^2 + 108xy + 81y^2 + 64x^2 + 192 xy + 144y = 100x^2 + 300xy + 225y^2
36x^2 + 64x^2 + 108xy + 192xy + 81y^2 + 144y^2 = 100x^2 + 300xy + 225y^2
100x^2 + 300xy + 225y^2 = 100x^2 + 300xy + 225y^2
The two sides are equal, so it is an identity.
Answer:
see below
Step-by-step explanation:
a The pythagorean theorem is a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + b^2 = c^2
(6x+9y)^2 + (8x+12y)^2 = (10x + 15y)^2
b solve
(6x+9y)^2 + (8x+12y)^2 = (10x + 15y)^2
(6x+9y)(6x+9y) + (8x+12y)(8x+12y) = (10x + 15y)(10x+15y)
Factor out the common factors
3(2x+3y)3(2x+3y) + 4(2x+3y)4(2x+3y) = 5(2x+3y)5(2x+3y)
Rearrange
9 (2x+3y)^2 +16 (2x+3y)^2 = 25(2x+3y)^2
Divide each side by(2x+3y)^2
9 (2x+3y)^2/ (2x+3y)^2 +16 (2x+3y)^2/(2x+3y)^2 = 25(2x+3y)^2/(2x+3y)^2
9 + 16 = 25
25=25
This is true, so it is an identity

Step-by-step explanation:
This is math that involves the properties of exponents. For this problem, three rules are used:
[tex](ab)^c=a^cb^c\\\\(a^b)^c=a^{bc}\\\\a^{-b}=\dfrac{1}{a^b}[/tex]
So, your expression can be written as ...
[tex]\dfrac{(2a^2)^3}{b}=\dfrac{2^3(a^2)^3}{b^1}=8a^6b^{-1}[/tex]
The mathematics involved is about exponential notation and algebraic expressions. The expression (2a^2)^3/b simplifies to 8a^6b^-1.
Explanation:The math involved here is known as exponential notation and algebraic expressions. In the given expression (2a^2)^3/b, the power rule of exponents can be applied, where to simplify the power of a power, we multiply the exponents. Therefore, (2a^2)^3 becomes 2^3 * (a^2)^3 which equals 8a^6. The expression then becomes 8a^6/b. This can be rewritten as 8a^6b^-1 (since anything divided by b can be written as multiplied by b^-1) adhering to the ca^pb^q format. So, the equivalent form of the given expression is 8a^6b^-1.

Type 3 - 35 , 45 , 55, 65
WHEN YOU COMMENT PLEASE BE ONE HUNNA PERCENT!! AND JUST GIVE ME THE ANSWER
Answer:
In the first week, the number of type-1 cabinets produced was 15, the number of type-2 cabinets produced was 30, the number of type-3 cabinets produced was 65.Step-by-step explanation:
If we let a, b, c represent the numbers of type-1, type-2, and type-3 cabinets produced in the first week, respectively, we can write three equations in these unknowns:
a + b + c = 110 . . . . . total cabinets for the first weeka + 2b - c = 10 . . . . relationship of quantities in the first week3a +0b +c = 110 . . . . total cabinets in the second weekIt can be convenient to let a machine solver find the solution to this set of equations. Most graphing calculators can handle it, along with several web sites.
__
Solving by hand, we can subtract the second equation from twice the first. This gives ...
2(a +b +c) -(a +2b -c) - 2(110) -(10)
a +3c = 210 . . . . simplify
Subtracting this from 3 times the third equation gives ...
3(3a +c) -(a +3c) = 3(110) -(210)
8a = 120 . . . . . simplify
a = 15 . . . . . . . divide by 8
Using this in the third equation of the original set, we have ...
3·15 +c = 110
c = 65 . . . . . . subtract 45
Then, in the first equation, we get ...
15 + b + 65 = 110
b = 30 . . . . . . . subtract 80
The solution is (type-1, type-2, type-3) = (15, 30, 65) for the first week.
The problem provides a set of linear equations. Solving this system by substitution or elimination method will give the number of cabinets of each type produced each week. The equations are formed based on the conditions provided in the problem.
Explanation:From the information provided, we can use a system of equations to solve this. Let's denote the number of type-1 cabinets made in the first week as x , the number of type-2 cabinets as y, and the number of type-3 cabinets as z. The first condition in the problem gives us the equation x + 2y = z + 10. The total number of cabinets produced in each week is 110, so we get the equation x + y + z = 110 for the first week. From the second week's conditions, we know that no type-2 cabinets were made (y=0), the number of type-3 cabinets was the same (z=z) and the number of type-1 cabinets was three times as much as the first week (x=3x), this means 3x + 0 + z = 110.. Solving this system of equations will provide the number of cabinets produced for each type.

8. In a word game, you choose a tile from a bag, replace it, and then choose another. If there are 28 vowels and 12 consonants, what is the probability you will choose a consonant and then a vowel?
Answer:
The probability that you will choose a consonant and then a vowel is 0.21....
Step-by-step explanation:
Total no of tiles = 28 + 12 = 40
First you should choose a consonant = 12/40
Second you should choose a vowel = 28/40
So the probability you choose a consonant and then a vowel:
= 12/40 * 28/40
=336/1600
=0.21
So the probability that you will choose a consonant and then a vowel is 0.21....

Step-by-step explanation:
An inscribed angle is half the arc angle.
m∠MNQ = 80°/2
m∠MNQ = 40°
The angle between two chords is the average of the arc angles.
m∠AMB = (80° + 85°) / 2
m∠AMB = 82.5°
Florence Tyler invests $6,500 in a 4-year certificate of deposit that earns interest at an annual rate of 5% compounded daily. The amount per $1.00 is 1.221386. What is the interest earned to the nearest cent?
Answer:
The total interest earned is $1,439.
Step-by-step explanation:
Consider the provided information:
Florence Tyler invests $6,500 in a 4-year certificate of deposit that earns interest at an annual rate of 5% compounded daily.
Now, Use the formula: [tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Where, A is the total amount (after adding interest), P is the principal (investment or loan), r is the interest rate, n is compound, and t is the time (in years).
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
[tex]A=6500(1+\frac{0.05}{365} )^{4(365)}[/tex]
[tex]A=6500(1.00014)^{1460}[/tex]
[tex]A=6500(1.22139)[/tex]
[tex]A=7939.00918[/tex]
Therefore total interest earned is:
$7,939.00 - $6500 = $1,439.00
Hence, interest earned is $1,439.
What is the approximate length of arc s on the circle below? Use 3.14 for pi. Round your answer to the nearest tenth.
A. 5.6 in.
B. 6.3 in.
C. 14.3 in.
D. 25.1 in.
Answer:
B 6.3
Step-by-step explanation:
r = 8
l = 2*3.14*r
l = 50.24
s=l/360*45
s≈6.3
For this case we have that by definition, the arc length is given by:
[tex]Al = 2 \pi * r *\frac {a} {360}[/tex]
Where:
r: It's the radio
a: It is the angle of the sector
Then, according to the data we have:
[tex]Al = 2 \pi * 8 * \frac {45} {360}\\Al = 2 * 3.14 * 8 * \frac {45} {360}\\Al = 50.24 * \frac {45} {360}\\Al = 6.28[/tex]
Rounding we have 6.3in
Answer:
Option B
Determine if the sequence is algebraic or geometric, and find the common difference or ratio.
x 1 2 3 4
f(x) 3 9 27 81
A.) Algebraic, common difference = 3
B.) Algebraic, common difference = 6
C.) Geometric, common ratio = 3
D.) Geometric, common ration = 6
Answer:
Option C.) Geometric, common ratio = 3
Step-by-step explanation:
we know that
In a Geometric Sequence each term is found by multiplying the previous term by a constant
The constant is called the common ratio
In this problem we have
For x=1, f(1)=3
For x=2, f(2)=9
For x=3, f(3)=27
For x=4, f(4)=81
so
f(2)/f(1)=9/3=3 -----> f(2)=3*f(1)
f(3)/f(2)=27/9=3 -----> f(3)=3*f(2)
f(4)/f(3)=81/27=3 -----> f(4)=3*f(3)
f(n+1)/f(n)=3 -----> f(n+1)=3*f(n)
therefore
This is a Geometric sequence and the common ratio is equal to 3
The sequence is a geometric sequence with a common ratio of 3.
Explanation:The sequence given is a geometric sequence. A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this case, the common ratio can be found by dividing a term in the sequence by its preceding term. For example, if we divide the second term (9) by the first term (3), we get 3. The same goes for the rest of the terms in the sequence. Therefore, the correct answer is Option C: Geometric, common ratio = 3.
