Fine Furniture Company had a net income of $50,000. Accounts receivable increased by $30,000; inventory decreased by $20,000; amounts payable increased by $4,000; and salaries payable decreased by $1,000. The amount of cash flow from continuing operating activities under the indirect method is
Cash flow from operating activities is $43,000. Calculated by adjusting net income for changes in working capital items.
To calculate the cash flow from operating activities using the indirect method, we start with net income and adjust for changes in working capital.
Net Income = $50,000
Changes in Working Capital:
1. Accounts Receivable increased by $30,000, so we subtract $30,000.
2. Inventory decreased by $20,000, so we add $20,000.
3. Amounts Payable increased by $4,000, so we add $4,000.
4. Salaries Payable decreased by $1,000, so we subtract $1,000.
Now, let's calculate the cash flow from operating activities:
Cash flow from operating activities = Net Income + Changes in Working Capital
= $50,000 - $30,000 + $20,000 + $4,000 - $1,000
= $50,000 - $7,000
= $43,000
So, the amount of cash flow from continuing operating activities under the indirect method is $43,000.

If we assume that all possible poker hands (comprised of 5 cards from a standard 52 card deck) are equally likely, what is the probability of being dealt: a. a flush? (A hand is said to be a flush if all 5 cards are of the same suit. Note that this definition means that straight flushes (five cards of the same suit in numeric sequence) are also considered flushes.) b. one pair? (This occurs when the cards have numeric values a, a, b, c, d, where a, b, c, and d are all distinct.) c. two pairs?

The answer to the given question will be a) P(flush) = 0.0019 b) P(one pair) = 0.4225 c) P( two pairs) = 0.475 d) P(three of a kind) = 0.211 e) P(four of a kind) = 0.00024
What is probability?
It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed.
The probability of being dealt a flush:
For a suit there are 4 choices and 13C₅ choices for a card in that suit
Probability of flush = 4.( 13C₅)/52C₅
Probability of flush = 0.0019
The probability of being dealt one pair:
There are 13 possible values of a, 4C₂ choice for suit of a, 12C₃ value for b, c, d and 4 choices each for choosing the suit of b, c, d.
P(one pair) = (13.4C₂.12C₃.4.4.4)/52C₅
P(one pair) = 0.4225
The probability of being dealt two pairs:
There are 13C₂ possibility for the value of a and b, 4C₂ choices for suits of both a and b and 44 possibilities for c from the remaining cards.
P(2 pairs) = (13C₂.4C₂.4C₂.44)/(52C₅) = 0.475
The probability of being dealt three of a kind:
There are 13 possibilities for the value of a and 4C₃ choices for the suits of a, 12C₂ possibilities for both b and c and 4 choices of suits for both b and c.
P( three of a kind) = (13.4C₃.12C₂.4.4)/52C₅ = 0.211
The probability of being dealt four of a kind:
There are 13 possibilities of a and 4C₄ values for the suit of a and 48 choices of b from the remaining cards.
P(four of a kind) = (13.4C₄.48)/52C₅ = 0.00024

Find the vertices and foci of the hyperbola with equation quantity x plus one squared divided by sixteen minus the quantity of y plus five squared divided by nine = 1
Answer:
The vertices are (3 , -5) , (-5 , -5)
The foci are (4 , -5) , (-6 , -5)
Step-by-step explanation:
* Lets study the equation of the hyperbola
- The standard form of the equation of a hyperbola with
center (h , k) and transverse axis parallel to the x-axis is
(x - h)²/a² - (y - k)²/b² = 1
- The length of the transverse axis is 2 a
- The coordinates of the vertices are (h ± a , k)
- The coordinates of the foci are (h ± c , k), where c² = a² + b²
- The distance between the foci is 2c
* Now lets solve the problem
- The equation of the hyperbola is (x + 1)²/16 - (y + 5)²/9 = 1
* From the equation
# a² = 16 ⇒ a = ± 4
# b² = 9 ⇒ b = ± 3
# h = -1
# k = -5
∵ The vertices are (h + a , k) , (h - a , k)
∴ The vertices are (-1 + 4 , -5) , (-1 - 4 , -5)
* The vertices are (3 , -5) , (-5 , -5)
∵ c² = a² + b²
∴ c² = 16 + 9 = 25
∴ c = ± 5
∵ The foci are (h ± c , k)
∴ The foci are (-1 + 5 , -5) , (-1 - 5 , -5)
* The foci are (4 , -5) , (-6 , -5)
Answer:
Vertices: (3,-5) (-5,-5)
Foci: (-6,-5) (4,-5)
Step-by-step explanation:
(x+1)^2/16-(y+5)^2/9 =1
formula: (x-h)^2/a^2 -(y-k)^2/b^2=1
in this case...
a^2=16 b^2=9
h=-1 k=-5
a=4 b=3
v=(h+/-a,k)
v1=(-1+4,-5)=
v1=(3,-5)
v2=(-1-4, -5) =
v2=(-5,-5)
Foci=(h+/-c,k)
F1=(h-c,k)
=(-1-5,-5)
f1=(-6,-5)
F2=(h+c,k)
=(-1+5, -5)
F2=(4,-5)

A school, hospital, and a supermarket are located at the vertices of a right triangle formed by three highways. The school and hospital are 14.7 miles apart. The distance between the school and the supermarket is 8.82 miles, and the distance between the hospital and the supermarket is 11.76 miles.
A service road will be constructed from the main entrance of the supermarket to the highway that connects the school and hospital. What is the shortest possible length for the service road? Round to the nearest tenth.
Answer:
7.1 miles
Step-by-step explanation:
Consider right triangle HospitalSchoolSupermarket. In this triangle:
HospitalSchool = 14.7 mi;HospitalSupermaket = 11.76 mi;School Supermarket = 8.82 mi.The shortest road from the main entrance of the supermarket to the highway that connects the school and hospital will be the height drawn from the point Supermarket to the hypotenuse HospitalSchool.
Let the length of this road be x mi and the distance from School to point A be y mi. Use twice the Pythagorean theorem for right triangles Supermarket SchoolA and SupermarketHospitalA:
[tex]\left\{\begin{array}{l}x^2+y^2=8.82^2\\ \\x^2+(14.7-y)^2=11.76^2\end{array}\right.[/tex]
Subtract from the second equation the first one:
[tex]x^2+(14.7-y)^2-x^2-y^2=11.76^2-8.82^2\\ \\14.7^2-2\cdot 14.7y+y^2-y^2=11.76^2-8.82^2\\ \\-29.4y=11.76^2-8.82^2-14.7^2\\ \\29.4y=155.5848\\ \\y\approx5.24\ mi[/tex]
Thus,
[tex]x^2=8.82^2-5.24^2=50.3348\\ \\x\approx 7.1\ mi.[/tex]

MELVIN MOWS A LAWN. THE FRACTION OF THE AWN THAT MELVIN HA MOWED SO FAR IS REPRESENTED BY THE SHADED MODEL SHOWN. MELVIN WILL MOW 3/10 MORE OF THE LAWN BEFORE HE TAKES HIS FIRST BREAK. WHAT FRACTION OF THE LAWN WIK MELVIN HAVE MOWED WHEN HE TAKES HIS FIRST BREAK?
Final answer:
To find the total fraction of the lawn mowed by Melvin before his first break, one would add the additional 3/10 to the already mowed fraction represented by the shaded model.
Explanation:
The student's question is about calculating the fraction of the lawn that will be mowed by Melvin before he takes his first break. Initially, the question does not specify what fraction of the lawn is already mowed, but indicates that Melvin will mow an additional 3/10 of the lawn. Assuming that the shaded model represents the fraction already mowed (let's say x), the total fraction mowed before Melvin's first break would be x + 3/10. Without the specific value of the initially mowed fraction, we cannot provide the exact answer; however, generally, the operation would involve adding the given fraction to Melvin's progress before he mows the additional 3/10.

26 37 18 45 20 36 22 25 50 41
Answer:
1. 37
2. 25
Step-by-step explanation:
In order to find a percentile of a given number set, you must first put the values in ascending order:
18, 20, 22, 25, 26, 36, 37, 41, 45, 50
70% = 0.7
Since there are 10 numbers in the set, we'll multiply 10 by 0.7
10 × 0.7 = 7
So we are going to look at the seventh number in the set.
18, 20, 22, 25, 26, 36, 37, 41, 45, 50
1 2 3 4 5 6 7 8 9 10
The seventh number in the set is 37.
We're going to do the same for finding the 40th percentile:
40% = 0.4
10 × 0.4 = 4
Finding the fourth number in the set...
18, 20, 22, 25, 26, 36, 37, 41, 45, 50
1 2 3 4 5 6 7 8 9 10

Serena asked her parents if for their picnic they could have 20% more portions of coca-cola than they planned, and if each portion could be 20% bigger. Her parents agreed. By what percent more coca cola will they buy?
Answer:
44%
Step-by-step explanation:
If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.
After p is increased by 20%, its number is ...
p + 0.20·p = 1.20·p
After q is increased by 20%, its amount is ...
q + 0.20 ·q = 1.20·q
Then the new amount the parents must buy is ...
(1.20p)(1.20q) = 1.20²·pq = 1.44pq
This amount is ...
(1 + 44/100)·pq = pq + 44%·pq
It is 44% more than the original planned purchase.

Step-by-step explanation:
The sequence is an arithmetic sequence with first term 7 and common difference -8. Since you're numbering the terms starting with n=0, the generic case will be ...
recursive: f(0) = first term; f(n) = f(n-1) + common difference
explicit: f(n) = first term + n·(common difference)
To get the answer above, fill in the first term and common difference values.
A 12-foot ladder is leaning up against a wall, as shown. how high does the ladder reach up the wall when x is 30°? 45°? 60°? round decimal answers to the nearest tenth, if necessary.
Answer:
6ft for 30°
8.5ft for 45°
10.4ft for 60°
Step-by-step explanation:
12(sin 30°)=x
x=6
12(sin 45°)=x
x=8.5
12(sin 60°)=x
x=10.4
By using right angle trigonometry and the cosine function (x = L cos θ), we find that a 12-ft ladder reaches 10.4 ft, 8.5 ft and 6 ft up a wall when it is leaned at 30°, 45° and 60° respectively.
Explanation:The problem described here involves the use of right angle trigonometry, specifically the use of the cosine function. In order to determine how high up the wall the ladder reaches at an angle of 30°, 45° and 60°, we can use the formula: x = L cos θ.
Firstly, let's calculate the height at 30 degrees (θ = 30°). We know that cos 30° = √3/2, so we substitute into the formula: x = 12ft * √3/2 which approximately equals 10.4 ft.
Next, for 45 degrees (θ = 45°), cos 45° = √2/2. Substituting into the formula: x = 12ft * √2/2 = 8.5 ft.
Finally, for 60 degrees (θ = 60°), cos 60° = 1/2. Therefore, x = 12ft * 1/2 = 6ft). So, the ladder reaches 10.4 ft up the wall when the angle is 30°, 8.5 ft when the angle is 45°, and 6 ft when the angle is 60°.
