Approximately 17.65% of Ana's salary is withheld for taxes.

To calculate the percentage of Ana's salary that is withheld for taxes, we need to determine the amount of tax withheld and then express it as a percentage of her net salary.

Number of hours worked per week (H) = 25 hours

Hourly wage (W) = $10

Net salary (S) = $212.50

Calculate the total earnings before taxes:

Total earnings = Hours worked * Hourly wage

Total earnings = 25 hours * $10/hour

Total earnings = $250

Determine the amount of tax withheld:

Tax withheld = Total earnings - Net salary

Tax withheld = $250 - $212.50

Tax withheld = $37.50

Calculate the percentage of salary withheld for taxes:

Percentage withheld = (Tax withheld / Net salary) * 100

Percentage withheld = ($37.50 / $212.50) * 100

Percentage withheld ≈ 17.65%

Therefore, approximately 17.65% of Ana's salary is withheld for taxes.

Answer: The best problem solving strategy to solve this problem with is a formula. Additionally Brandon had $12.50 before going to the store.

Step-by-step explanation: Formula and Solving it

He Spent $2.50 on pencils.

Amount left after buying a pencil = x - 2.50

Next, he spent half of the amount left in his pocket.

He spent (x - 2.50)/2 on notebook and paper.

So the total amount he spent = 2.50 + (x -2.50)/2

Amount left when he got home =$ 5.00

That means, x - Total amount spent = 5

=> x - (2.50 + (x -2.50)/2 ) = 5

=> x - 2.50 -x/2 + 2.50/2 = 5

=> x/2 - 2.50/2 = 5

=> x/2 = 5 + 2.50/2

=> x/2 = 6.25

=>x = $12.5

b = number of beetles

r = number of birds

s = number of spiders

"She has an equal number of beetles, birds and spiders". That means b = r = s. They all stand in for the same number, and that number being some positive whole number.

One spider has 8 legs, so s of them have 8s legs. One beetle has 6 legs, so b of them have 6b legs. One bird has 2 legs, so r birds have 2r legs.

In total, all of the animals have 6b+2r+8s legs. We'll replace r and s with b, since earlier we were given that b = r = s.

So we end up with:

6b+2r+8s

6b+2b+8b

(6+2+8)b

16b

The number of legs of all the animals is equal to 16 times the number of beetles. Set this equal to 270 and isolate b

The value of the equation (1 - x)/2x² + x²/(2x - 2) is 0 if x² + x - 1 = 0

From the question, the equation is given as

x² + x - 1 = 0

Make x² the subject of the above equation

So, we have the following equation

x²  = 1 - x

The equation to calculate is given as

(1 - x)/2x² + x²/(2x - 2) = ?

Substitute x²  = 1 - x

(1 - x)/2x² + x²/(2x - 2) = x²/2x² + x²/(2x - 2)

Evaluate the quotient

So, we have the following equation

(1 - x)/2x² + x²/(2x - 2) = 1/2 + x²/(2x - 2)

Factor out -2

(1 - x)/2x² + x²/(2x - 2) = 1/2 - x²/2(1 - x)

Substitute x²  = 1 - x

Factor out -2

(1 - x)/2x² + x²/(2x - 2) = 1/2 - x²/2x²

Evaluate the quotient

(1 - x)/2x² + x²/(2x - 2) = 1/2 - 1/2

Evaluate the difference

(1 - x)/2x² + x²/(2x - 2) = 0

Hence, the solution to the equation is 0

The question is improper. Proper question is given below;

What two variables are likely to have a negative correlation

Answer:

y = (x + 6)² - 1

Step-by-step explanation:

So there are two ways of doing it, completing the square or partial factoring (which is what i prefer and will show)

so we will get x first:

x^2+12x

We are factoring x

x(x+12)

Now you do x=-12/2

x=-6

Now that you have x, you plg that back into the equation to get y

y= -6^2 +12(-6) +35

= 36-36+35

Put into vertex form

y = (x + 6)² - 1

Answer:

1. (-4)^2 = 16

2. (-3)^3 = -27

Step-by-step explanation:

========================================

Work Shown:

The two points we have are \((x_1,y_1) = (2,1.2)\) and \((x_2,y_2) = (2,2.5)\)

Apply the distance formula

\(d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(2-2)^2+(1.2-2.5)^2}\\\\d = \sqrt{(0)^2+(-1.3)^2}\\\\d = \sqrt{0+1.69}\\\\d = \sqrt{1.69}\\\\d = 1.3\\\\\)

-------------------------

A shortcut is possible by subtracting the y coordinates of the two points, and making the result positive through the use of absolute value.

So we either say

|y1-y2| = |1.2-2.5| = |-1.3| = 1.3

or,

|y2 - y1| = |2.5 - 1.2| = |1.3| = 1.3

We get the same result. This shortcut is valid because the x coordinates of both points are the same.

Given statement solution is :- Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

To analyze the steady matrix for this situation, let's consider the two groups of customers: those who turn in tickets and those who do not turn in tickets.

Let's denote the proportion of customers who turn in tickets as X and the proportion of customers who do not turn in tickets as Y.

According to the given information:

40% of the customers who turn in tickets do not turn in tickets the following week. This means that 60% of the customers who turn in tickets will turn in tickets again the following week.

30% of the customers who do not turn in tickets will turn in tickets the following week. This means that 70% of the customers who do not turn in tickets will continue not turning in tickets the following week.

Based on these percentages, we can construct the steady matrix:

Copy code

     |  Customers turning in tickets (X) | Customers not turning in tickets (Y) |

----------|----------------------------------|--------------------------------------|

Next week 0.6 0.3

This week 0.4 0.7

Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The value 0.4 in the bottom left cell represents the proportion of customers who do not turn in tickets this week but will turn in tickets next week.

The value 0.7 in the bottom right cell represents the proportion of customers who do not turn in tickets this week and will continue not turning in tickets next week.

These values describe the transition probabilities between the two customer groups. For example, if there are 100 customers in total, 60 of them will turn in tickets next week, and 40 of them will not. Similarly, 30 customers who turn in tickets this week will not do so next week, while 70 customers who do not turn in tickets this week will continue to not turn them in next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

10 multiplied by 12 is 120

12 multiplied by 5 is 60

60 divided by 2 is 30

2 lots of 30 is 60

5 multiplied by 10 is 50

130 add 120 add 60 add 50 is 360cm squared

\(sa = bh + ( b_{1} + b_{2} + b_{3})l\)

\(sa = 12(5) + (5 + 12 + 13) \times 10\)

\(sa = 60 + (30)(10)\)

\(sa = 60 + 300\)

\(sa = 360 \: {m}^{2} \)

Hence, the surface area of the given triangular prism is 360 square meters.

Answer:

Step-by-step explanation: I am trying to interpret the question: I'll assume:

Line AB has a midpoint, M.

A is (8,4)

B is unknown, but desired

M is (3,-2)

We'll assume a straight line of the form y=mx+b, where m is the slope. m can be calculated by the "Rise" over the "Run" between the points A and M:

Rise = (4-(-2))=6

Run = (8-3)=5

Slope = (Rise/Run) = (6/5)

The line becomes y=(6/5)x+b

Calculate b, the y-intercept (the value of y when x is 0), by entering one of the two known points. I'll choose (8,4).

y=(6/5)x+b

4 = (6/5)(8)+b

b = 4 - (6/5)(8)

b = 4 - (48/5)

b = 4 - (9 3/5) or -5 3/5

The equation becomes:

y=(6/5)x - 5 3/5

Point B will have an x value of -2 [The change in x from A to M was (3-8) = -5. From M to 5 would be another -5 increment, so x goes from 3 to (3-5) or -2.

Find the value of y for x=-2:

y=(6/5)x - 5 3/5

y=(6/5)*(-2) - 5 3/5

y=(-12/5) - (28/5)

y = -(40/5) or - 8

B has coordinates of (-2, -8)

If coordinates of point A is (8, 4), then the coordinate of point B will be (-2, -8).

The "Midpoint-Formula" is used to find the coordinates of a point that lies exactly halfway between two given points. It's given as :Midpoint (M) = ((x₁ + x₂)/2, (y₁ + y₂)/2),

In this case, we have the midpoint as M(3, -2) and one of the endpoints as A(8, 4). We need to find coordinates of other endpoint which is B,

Using the midpoint formula, we rearrange it to solve for the missing coordinates (x₂, y₂),

x₂ = 2 × Mₓ - x₁,

y₂ = 2 × \(M_{y}\) - y₁,

Substitute the given values:

We have : Mₓ = 3; \(M_{y}\) = -2,

x₁ = 8; y₁ = 4

x₂ = 2 × 3 - 8 = -2;   y₂ = 2 × -2 - 4 = -8,
