The true statements are

Dilation was performed on a rectangle with a center of dilation at point V. We will evaluate the given options to determine their accuracy:

Option 1: The image is a reduction because 0 < n < 1 (True)

Explanation: Since the dilation factor is 2/5, this is less than 1, the resulting image will be smaller than the original rectangle. Therefore, this option is true.

Option 2: This is true.  Dilation preserves the proportional relationship between corresponding sides of similar shapes. Since the dilation factor is 2/5, the side lengths of the image will be two-fifths the length of the corresponding side lengths of the pre-image. Therefore, this option is true.

Option 5: is true Since the dilation factor is 2/5, the base of the image will be two-fifths the length of the base of the pre-image. This is in line with the proportional relationship preserved by dilation. Therefore, this option is true.

In summary, options 1, 2, and 5 are true, while options 3 and 4 are false.

The coordinates of the remaining corners are (2, 2) and (2, 10).

To find the coordinates of the remaining corners of the parallelogram, we can use the fact that the diagonals of a parallelogram bisect each other.

Let's call the point of intersection of the diagonals as (3, 4). The midpoint of one diagonal is the same as the midpoint of the other diagonal.

First, let's find the midpoint of the diagonal connecting (3, 2) and (5, 10). The midpoint formula is given by:

Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Applying this formula, we find the midpoint as (4, 6).

Since the point (3, 4) is the midpoint of the other diagonal, we can use this information to find the coordinates of the remaining corners.

If we reflect the point (4, 6) across the point of intersection (3, 4), we will obtain the coordinates of the remaining corners.

Reflecting (4, 6) across (3, 4), we get:

(4 - 2, 6 - 4) = (2, 2)

Therefore, the remaining corners of the parallelogram are (2, 2) and (2, 10).

(a) Probability that 3 balls are all white:

Step 1:

Total balls = Number of red balls + Number of white balls + Number of green balls = 7 + 12 + 4 = 23.

Step 2:

Total ways to choose 3 balls = C(23, 3) = 23! / (3 * (23-3) ) = 23 / (3 * 20) = (23 * 22 * 21) / (3 * 2 * 1) = 1771.

Step 3: Calculate the number of ways to choose 3 white balls out of 12:

Number of ways to choose 3 white balls = C(12, 3) = 12 / (3 * (12-3) ) = 12 / (3 * 9) = (12 * 11 * 10) / (3 * 2 * 1) = 220.

Step 4: Calculate the probability of selecting 3 white balls:

Probability = Number of ways to choose 3 white balls / Total ways to choose 3 balls = 220 / 1771 ≈ 0.1241.

Therefore, the probability that 3 balls drawn are all white is approximately 0.1241.

(b) Probability that 3 balls are one of each color:

Step 1: Calculate the total number of balls in the bag (same as above): Total balls = 23.

Step 2: Calculate the total number of ways to choose 3 balls out of 23 (same as above): Total ways to choose 3 balls = 1771.

Step 3: Calculate the number of ways to choose 1 ball of each color:

Number of ways to choose 1 red, 1 white, and 1 green ball = Number of red balls * Number of white balls * Number of green balls = 7 * 12 * 4 = 336.

Step 4: Calculate the probability of selecting 3 balls of different colors:

Probability = Number of ways to choose 1 ball of each color / Total ways to choose 3 balls = 336 / 1771 ≈ 0.1899.

Therefore, the probability that 3 balls drawn are one of each color is approximately 0.1899.

(c) Probability that 3 balls are of the same color:

Step 1: Calculate the total number of balls in the bag (same as above): Total balls = 23.

Step 2: Calculate the total number of ways to choose 3 balls out of 23 (same as above): Total ways to choose 3 balls = 1771.

Step 3: Calculate the number of ways to choose 3 balls of the same color:

Number of ways to choose 3 red balls = C(7, 3) = 7 / (3 * (7-3) ) = 7 / (3 * 4 ) = (7 * 6 * 5) / (3 * 2 * 1) = 35.

Number of ways to choose 3 white balls = C(12, 3) = 220.

Number of ways to choose 3 green balls = C(4, 3) = 4.

Step 4: Calculate the probability of selecting 3 balls of the same color:

Probability = (Number of ways to choose 3 red balls + Number of ways to choose 3 white balls + Number of ways to choose 3 green balls) / Total ways to choose 3 balls = (35 + 220 + 4) / 1771 ≈ 0.1416.

Therefore, the probability that 3 balls drawn are of the same color is approximately 0.1416.

Answer:

Step-by-step explanation:

(a) Probability that 3 balls are all white:

Total number of balls = 7 red + 12 white + 4 green = 23

Number of favorable outcomes = 12 white balls

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 12 / 23

(b) Probability that 3 balls are one of each color:

Total number of balls = 7 red + 12 white + 4 green = 23

Number of favorable outcomes = 7 red balls * 12 white balls * 4 green balls

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = (7 * 12 * 4) / (23 * 22 * 21)

(c) Probability that 3 balls are the same color:

Total number of balls = 7 red + 12 white + 4 green = 23

Number of favorable outcomes = (7 red balls * 6 red balls * 5 red balls) + (12 white balls * 11 white balls * 10 white balls) + (4 green balls * 3 green balls * 2 green balls)

Let the cost of a ruler be represented by r, then we have:

m Shillings is the cost of a pen and r Shillings is the cost of a ruler from the given information.Using the information, the cost of the ruler will be the cost of a pen minus 5.

This can be represented algebraically as:r = m - 5

To find the cost of 4 pens and 6 rulers, we can substitute the value of r from the equation above into the expression for the cost of 4 pens and 6 rulers.Cost of 4 pens = 4mCost of 6 rulers = 6r

Substituting r from the equation above into the expression for the cost of 6 rulers, we have:Cost of 6 rulers = 6(m - 5)Simplifying the expression above, we get:Cost of 6 rulers = 6m - 30

Therefore, the algebraic expression for the costs of 4 pens and 6 rulers is:

Total cost = Cost of 4 pens + Cost of 6 rulersTotal cost = 4m + (6m - 30)Total cost = 10m - 30Hence, the algebraic expression for the costs of 4 pens and 6 rulers is 10m - 30.

The contractor has a maximum of 29 hours (rounded down) to complete the job while keeping the total cost under $2000.

To find the number of hours the contractor has for the job while keeping the total cost under $2000, we can use the given cost model equation: C = 43H + 750.

Since the owner wants the total cost to be under $2000, we can set up the inequality:

43H + 750 < 2000

Now, let's solve this inequality for H, the number of hours:

43H < 2000 - 750

43H < 1250

Dividing both sides of the inequality by 43:

H < 1250/43

To determine the maximum number of hours the contractor has for the job, we need to round down the result to the nearest whole number since the contractor cannot work a fraction of an hour.

Using a calculator, we find that 1250 divided by 43 is approximately 29.07. Rounding down to the nearest whole number, we get:

H < 29

Using the cost model equation C = 43H + 750, where C represents the total cost and H represents the number of hours, we set up the inequality 43H + 750 < 2000 to satisfy the owner's requirement of a total cost under $2000.

By solving the inequality and rounding down to the nearest whole number, we find that the contractor has a maximum of 29 hours to complete the job within the specified cost limit.

Answer:

B)  20°

Step-by-step explanation:

Given equation:

[tex]\sin \theta = \cos (\theta + 50^{\circ})[/tex]

To solve the given equation for θ, we can use a co-function identity.

Co-function identities are a set of trigonometric identities that relate the values of complementary angles.

[tex]\boxed{\begin{minipage}{5cm}\underline{Co-function Identities}\\\\$\sin \theta = \cos (90^{\circ}-\theta)$\\\\$\cos\theta = \sin(90^{\circ}-\theta)$\\\\\sin \theta=\cos\theta$,\;if\;$A+B=90^{\circ}$\\\end{minipage}}[/tex]

Using the cofunction identity sin θ = cos (90° - θ), we can say that:

[tex]\cos (90^{\circ} -\theta)=\cos (\theta + 50^{\circ})[/tex]

Therefore:

[tex]\begin{aligned} \theta + 50^{\circ} &= 90^{\circ} -\theta\\\theta + 50^{\circ} +\theta &= 90^{\circ} -\theta+\theta \\2 \theta+ 50^{\circ} -50^{\circ}&= 90^{\circ}\\2 \theta+ 50^{\circ} &= 90^{\circ} -50^{\circ}\\ 2 \theta&=40^{\circ}\\\theta&=20^{\circ}\end{aligned}[/tex]

Therefore, the value of θ is 20°.

Dan will pay approximately $1231.87 in cash for the fence.

To determine how much Dan will pay in cash for the fence, we need to calculate the total cost of the fence, apply the tax, and then determine the portion that will be paid with a credit card.

Dimensions of the land to be fenced: 450 ft by 280 ft

Length of a roll of fence: 60 ft

Cost of a roll of fence: $60.00

Tax rate: 9.5%

Portion to be paid with a credit card: 1/4 (or 25%)

First, let's calculate the total perimeter of the land to determine how many rolls of fence are needed:

Perimeter = 2 [tex]\times[/tex] (Length + Width)

Perimeter = 2 [tex]\times[/tex] (450 ft + 280 ft)

Perimeter = 2 [tex]\times[/tex] 730 ft

Perimeter = 1460 ft

Since each roll of fence is 60 ft long, the number of rolls needed is:

Number of rolls = Perimeter / Length of a roll

Number of rolls = 1460 ft / 60 ft

Number of rolls ≈ 24.33 rolls

Since we can't purchase a fraction of a roll, we need to round up to the nearest whole number of rolls.

Thus, we need to purchase 25 rolls.

The total cost of the fence without tax is:

Total cost = Number of rolls [tex]\times[/tex] Cost per roll

Total cost = 25 rolls [tex]\times[/tex] $60.00 per roll

Total cost = $1500.00

Now, let's calculate the tax amount:

Tax amount = Total cost [tex]\times[/tex] Tax rate

Tax amount = $1500.00 [tex]\times[/tex] 9.5% (or 0.095)

Tax amount = $142.50

The total cost including tax is:

Total cost with tax = Total cost + Tax amount

Total cost with tax = $1500.00 + $142.50

Total cost with tax = $1642.50

Finally, let's calculate the portion to be paid with a credit card and the portion to be paid in cash:

Portion paid with credit card = Portion to be paid with a credit card * Total cost with tax

Portion paid with credit card = 25% [tex]\times[/tex] $1642.50

Portion paid with credit card = $410.63

Portion paid in cash = Total cost with tax - Portion paid with credit card

Portion paid in cash = $1642.50 - $410.63

Portion paid in cash = $1231.87

Answer:

ok, here is your answer

Step-by-step explanation:

Using the formula for compound interest:

A = P (1 + r/n)^(nt)

where:

A = the total amount

P = the principal amount

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

Given:

P = €250

r = 9% = 0.09

n = 1 (compounded annually)

t = 3 years

Now, substituting the given values in the formula:

A = 250 (1 + 0.09/1)^(1*3)

A = 250 (1 + 0.09)^3

A = 250 (1.09)^3

A = 250 (1.29503)

A = €323.76 (rounded to two decimal places)

Therefore, the balance in the account at the end of 3 years would be €323.76.
