Based on the given figures, the most likely transformation that maps figure ABCD onto figure A'B'C'D' is option A, reflection across the Y-axis.

This is because the x-coordinates of the corresponding points in the two figures are opposite to each other when reflected across the Y-axis.  

A rotation of 90⁰ clockwise or counter-clockwise about the origin would result in the image being in a different quadrant, and a rotation of 180° about the origin would place the image on the opposite side of the origin.

A translation would move the image to a different location without changing its orientation, but there is no indication in the question that a translation is a possible transformation. Hence it's a reflection across Y-axis.

Answer:

h = -10

Step-by-step explanation:

The solution to the equation is h = -10. To solve for h, we need to isolate h on one side of the equation. We do this by adding 9 to both sides, subtract 4h from both sides, and add 5 to both sides. This gives us:

Negative 3 (h + 5) + 2 + 9 = 4 (h + 6) - 9 + 9

Negative 3h + 14 = 4h + 15

Negative 3h - 4h = 15 - 14

-7h = 1

h = -1/7

h = -10

The cost per pound of sausage, s, and brisket, b is 10s + 14b = 100.5

We are given that;

First customer order= $21

Second customer order= $100.50

Now,

The two equations that can be used to create a system of equations are:

2s + 3b = 21 10s + 14b = 100.5

These equations are obtained by multiplying the cost per pound of sausage and brisket by the number of pounds ordered by each customer and setting them equal to the total cost for each customer. The variables s and b represent the cost per pound of sausage and brisket, respectively.

Therefore, by the equation the answer will be 10s + 14b = 100.5

If the flow rate of the tap is reduced to 7 litres per minute, it would take 36 hours to fill the reservoir.

Let's use the formula:

time = volume/flow rate

where volume is the volume of the reservoir and flow rate is the flow rate of the tap.

Let V be the volume of the reservoir.

With a flow of 18 litres per minute, we have:

14 hours = V / 18 L/min

Solving for V, we get:

V = 14 hours x 18 L/min = 252 L

Now, let's find the time it takes to fill the same reservoir with a flow of 7 litres per minute:

time = V / 7 L/min

Substituting V with 252 L, we get:

time = 252 L / 7 L/min = 36 hours

Answer: The probability of choosing an ace or a club is 16.

Step-by-step explanation:

(C) Investment A is an ordinary annuity with 3,906.64 in the account after 1 year is correct option.

Both Investment A and Investment B are annuities, but we need to determine which one is an ordinary annuity. An ordinary annuity is one in which payments are made at the end of each period, while in an annuity due, payments are made at the beginning of each period.

Looking at the table, we can see that Investment A and Investment B both have payments made at the end of each month, so they are both examples of ordinary annuities.

To calculate the future value of each annuity after one year, we can use the formula:

[tex]FV = P \times [(1 + r)^n - 1] / r[/tex]

where:

FV is the future value of the annuity

P is the payment amount

r is the interest rate per period (in this case, 3.5% per month)

n is the number of periods (12 in this case, since we're looking at one year)

For Investment A, we have P = 350, r = 0.035, and n = 12. Plugging these values into the formula, we get:

FV = 350 × [(1 + 0.035[tex])^12[/tex] - 1] / 0.035

= 3,906.64

Therefore, the answer is (C) Investment A is an ordinary annuity with 3,906.64 in the account after 1 year.

A linear model that best fits the data include the following: D. y = -1.6881x + 92.571.

In this scenario, the time would be plotted on the x-axis (x-coordinate) of the scatter plot while the elevation of a snow boarder would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

On the Microsoft Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the line of best fit (trend line) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between the time and the elevation of a snow boarder, an equation for the line of best fit is given by:

y = -1.6881x + 92.571

Next, we would substitute the x-values into the equation for the line of best fit as follows;

When x = 0, we have:

y = -1.6881(0) + 92.571

y = 92.571 ≈ 93.

When x = 5, we have:

y = -1.6881(5) + 92.571

y = 84.1305 ≈ 84.

When x = 10, we have:

y = -1.6881(10) + 92.571

y = 75.69 ≈ 76.

In conclusion, we can logically conclude that the slope of this graph (line) is negative because the line decreases downward, and this is best modeled by only this equation y = -1.6881x + 92.571.

The possible equation for Nate's line is C) 6x - 5y = 15.

To find the equation of the line perpendicular to Maria's line, we need to determine the slope of Maria's line first.

Maria's line is represented by the equation:

y = -5/6 x + 8

The slope of this line can be determined by comparing it to the slope-intercept form of a linear equation (y = mx + b), where m is the slope. Thus, the slope of Maria's line is -5/6.

The slope of a line perpendicular to Maria's line will be the negative reciprocal of -5/6, which is 6/5.

Therefore, the equation of Nate's line could be in the form:

y = 6/5 x + b

where b is the y-intercept of Nate's line.

To determine which of the given answer choices is the equation of Nate's line, we can substitute the equation y = 6/5 x + b into each answer choice and see which one holds true.

A) 5x - 6y = 15

Substituting y = 6/5 x + b, we get:

5x - 6(6/5 x + b) = 15

5x - 36/5 x - 6b = 15

-11/5 x - 6b = 15

This equation is not equivalent to y = 6/5 x + b, so A is not the answer.

B) 5x + 6y = 15

Substituting y = 6/5 x + b, we get:

5x + 6(6/5 x + b) = 15

5x + 36/5 x + 6b = 15

46/5 x + 6b = 15

This equation is not equivalent to y = 6/5 x + b, so B is not the answer.

C) 6x - 5y = 15

Substituting y = 6/5 x + b, we get:

6x - 5(6/5 x + b) = 15

6x - 6x - 5b = 15

-5b = 15

b = -3

This equation is equivalent to y = 6/5 x - 3, so C could be the answer.

D) 6x + 5y = 15

Substituting y = 6/5 x + b, we get:

6x + 5(6/5 x + b) = 15

6x + 6x + 5b = 15

12x + 5b = 15

This equation is not equivalent to y = 6/5 x + b, so D is not the answer.

Entertainment will comprise 90% of Ryan's total budget. He will allocate 90% of his monthly income towards entertainment expenses.

According to the given information:

Let's assume Ryan's take-home pay is P dollars.

Assuming that Ryan puts aside 10% of his net income for his retirement plan, he will accumulate savings of 0.10P dollars.

After setting aside funds for retirement, the remaining portion of his net earnings will constitute 90% of the original amount, equating to 0.90P dollars.

Assuming that Ryan puts the remaining amount of his income towards entertainment, it is possible to determine the proportion of his overall expenses that entertainment would represent.

Percentage of entertainment budget = (Entertainment budget / Total budget) * 100

Given an overall budget of P dollars, with 0.90P dollars allotted for entertainment expenses, the proportion of the total budget that will be spent on entertainment can be calculated as a percentage.

Percentage of entertainment budget = (0.90P / P) * 100

Percentage of entertainment budget = 90%

So, entertainment will comprise 90% of Ryan's total budget.

He will allocate a monthly entertainment budget of 0.90P dollars, equivalent to 90% of his salary after taxes.
