Answer: 7
Step-by-step explanation: I got 7. Here's how I got it:
Use the process of elimination. The 2 cannot be divided by 3, because the number (3) we are dividing by, is greater than the primary number (2). If we divided 3 by 2, we would result in a decimal. Then, I took an estimate. I got rid of the 3 because that number would be a low number to divide by 3.
Then I started plugging in numbers:
(6*2) + 5 + 1 + 4 = 22
As we know, 22 is NOT a product of 3.
So, it has to be 7, but I'll prove my answer:
(7*2) + 5 + 1 + 4 = 24
And yes, 24 can be divided by 3 8 times. I hope this helps.
Clarification: I multiply 6 and 7 by 2 because both numbers would go into the 2 boxes.
If MNP~QRP, find MP (urgent please help!!!!)
Two or more figures are said to be similar when they have common properties. The value of MP is 18 units.
More than one figure are said to be similar if they have some relatable common properties, either considering their length of sides or measure of their internal angles. But similarity is not the same as congruence.
In the given question, it can be deduced that ΔMNP is similar to ΔQRP. Thus, relating the corresponding sides of the two triangles we have;
[tex]\frac{12}{30}[/tex] = [tex]\frac{5x-2}{11x+1}[/tex]
cross multiply to have
30(5x-2) = 12(11x+1)
150x - 60 = 132x + 12
collect like terms
150x - 132x = 12 + 60
18x = 72
x = 4
So that,
MP = 5x - 2
= 5(4) - 2
= 20 -2
MP = 18 units

A line passes through the points (20, 2) and (10, 1). What is its equation in slope-intercept
form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
[tex]y = \frac{1}{10}x[/tex]
Step-by-step explanation:
⭐ What is slope-intercept form?
[tex]y = mx + b[/tex]"m" is the slope"b" is the y-intercept (the y-value for when x = 0)First, we need to find the value of "m" using the slope formula.
⭐ What is the slope formula?
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex][tex](x_1,y_1)[/tex] is a coordinate that you are given[tex](x_2,y_2)[/tex] is another coordinate that you are givenSubstitute the two coordinates you are given into the slope formula.
[tex]m = \frac{1-2}{10-20}[/tex]
[tex]m = \frac{-1}{-10}[/tex]
[tex]m = \frac{1}{10}[/tex]
Substitute the value of "m" into the slope-intercept form equation.
[tex]y = \frac{1}{10}x + b[/tex]
Next, we need to find the value of "b". To do so, substitute a coordinate that you are given into the equation and solve for "b".
I am going to use (10,1), but you can also use (20,2).
[tex]1 = \frac{1}{10} (10) + b[/tex]
[tex]1 = 1 + b[/tex]
[tex]0 = b[/tex]
Substitute the value of "b" into the slope-intercept form equation.
[tex]y = \frac{1}{10}x[/tex]

Andre has a summer job selling magazine subscriptions. He earns $25 per week plus $3 for every subscription he sells. Andre hopes to make at least enough money this week to buy a new pair of soccer cleats.
Write an inequality to describe the number of subscriptions Andre must sell to reach his goal.
The inequality to describe the number of subscriptions is 25 + 3x ≥ A
How to determine the inequality to describe the number of subscriptionsFrom the question, we have the following parameters that can be used in our computation:
Earnings per week = $25
Commission = $3 on every subscription
This means that the total earning can be calculated using
Total earnings = Earnings per week + Commission x Number of subscriptions
Substitute the known values in the above equation, so, we have the following representation
y = 25 + 3x
He hopes to make at least enough money this week to buy a new pair of soccer cleats

What is an angle of a triangle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Given that ∠JKI = (5x−3)⁰, ∠KIJ=(2x+8)⁰, and ∠IJK=(x−1)⁰.
The sum of all angles of a triangle is 180⁰.
(5x−3)⁰ + (2x+8)⁰ + (x−1)⁰ = 180⁰
(5x + 2x + x) + ( - 3 + 8 -1) = 180
8x + 4 = 180
Subtract 4 from both sides:
8x = 176
x = 22
Putting x = 22 in ∠JKI = (5x−3)⁰:

What are even functions?For an even function, f(x) = f(-x). Even functions are symmetric about the y-axis.
What is meant by symmetric about y axis?Symmetricity about y-axis means that for same magnitude of x (like -2 and 2 have the same magnitude that is 2) the value of y will be the same.

Write the equation of the hyperbola with center (1,-3), vertex (1,2), and focus (1,-3+2sqrt10)
Answer:
option c
Step-by-step explanation:
Answer:
[tex]\textsf{b)} \quad \dfrac{(y+3)^2}{25}-\dfrac{(x-1)^2}{15}=1[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Standard equation of vertical hyperbola}\\\\$\dfrac{(y-k)^2}{a^2}-\dfrac{(x-h)^2}{b^2}=1$\\\\where:\\\phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $(h, k\pm a)$ are the vertices. \\\phantom{ww}$\bullet$ $(h\pm b, k)$ are the co-vertices. \\\phantom{ww}$\bullet$ $(h, k\pm c)$ are the foci where $c^2=a^2-b^2$.\\\end{minipage}}[/tex]
Given:
center (1, -3)vertex (1, 2)focus (1, -3+2√10)As the x-values of the given center, vertex and focus are the same, the hyperbola is vertical (opening up and down).
Given the center is (1, -3):
h = 1k = -3Use the vertices formula (h, k±a) to find a:
[tex]\begin{aligned} (h, k \pm a) = (1, -3 \pm a) &= (1, 2)\\\implies -3 \pm a &= 2\\a &= 5\end{aligned}[/tex]
Use the foci formula (h, k±c) to find c:
[tex]\begin{aligned} (h, k \pm c) = (1, -3 \pm c)&=(1, -3 \pm 2\sqrt{10})\\c &= 2 \sqrt{10}\end{aligned}[/tex]
Use the found values of a and c with Pythagoras Theorem to find b²:
[tex]\begin{aligned}c^2 &=a^2+b^2\\\implies (2 \sqrt{10})^2&=5^2+b^2\\40&=25+b^2\\b^2&=15\end{aligned}[/tex]
Therefore:
h = 1k = -3a² = 5² = 25b² = 15Substitute the found values into the hyperbola formula to create an equation of the hyperbola with the given parameters:

Question 9 An S corporation is generally set up to: a)implement an expansion strategy b)attract capital c)reduce tax burdens d)easy entry into an industry e)take advantage of limited liability
All of the above options a) implement an expansion strategy b)attract capital c)reduce tax burdens d)easy entry into an industry e)take advantage of limited liability ,are correct.
A corporation is generally set up to take advantage of limited liability. This means that the owners of the corporation (the shareholders) are not personally responsible for the debts and obligations of the corporation. The other options you have listed are also potential reasons for setting up a corporation, but they are not the primary purpose of a corporation.
An expansion strategy refers to a company's plan for growth and expansion, and setting up a corporation can be one way to implement this strategy. Attracting capital refers to the process of raising funds for a business, and a corporation may be able to attract more capital because it is a separate legal entity that can issue stocks and bonds. Reducing tax burdens refers to the process of minimizing the amount of taxes a business has to pay, and a corporation may be able to do this because it is taxed as a separate entity. Finally, setting up a corporation can also make it easier for a business to enter an industry because it provides a legal framework for the business and can make it easier to raise capital.

a biased coin has the probability that a head comes up when flipped is 0.35.what is the expected number of heads that come up when it is flipped ten times?
This means that the probability of getting exactly 3 heads in ten flips is about 24.1%.
The probability of getting a specific number of heads in a given number of flips follows a binomial distribution, which describes the probability of getting a certain number of successes in a given number of independent trials. The probability of getting a specific number of heads in ten flips can be calculated using the formula:
P(x heads in n flips) = (n choose x) * p^x * (1-p)^(n-x)
where p is the probability of getting a head on each flip and x is the number of heads.
For example, the probability of getting exactly 3 heads in ten flips is:
P(3 heads in 10 flips) = (10 choose 3) * 0.35^3 * (1-0.35)^(10-3) = 0.241

The first dimension, 4, represents the number of rows in the array, and the second dimension, 9, represents the number of columns. This means that the array A has a total of 4 rows and 9 columns, for a total of 4 × 9 = 36 storage locations.
Here's an example of how the array A might be structured in memory:[tex]A[0,0] \ A[0,1] \ A[0,2] \ A[0,3] \ A[0,4] \ A[0,5] \ A[0,6] \ A[0,7] \ A[0,8]\\A[1,0] \ A[1,1] \ A[1,2] \ A[1,3] \ A[1,4] \ A[1,5] \ A[1,6] \ A[1,7] \ A[1,8]\\A[2,0] \ A[2,1] \ A[2,2] \ A[2,3] \ A[2,4] \ A[2,5] \ A[2,6]\ A[2,7] \ A[2,8]\\A[3,0] \ A[3,1] \ A[3,2] \ A[3,3] \ A[3,4] \ A[3,5] \ A[3,6] \ A[3,7] \ A[3,8][/tex]
