The scale factor applied for each dilation are-

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

The form will be smaller if the scaling factor is a fraction. Reduction is the term for this. Therefore, a scaling factor of 1/2 suggests that the fresh shape is equal to half of the old shape.

Part a: For ΔABC

Length AB = 2 units

Length A'B' = 4 units

A'B' = 2 *AB

Hence,  For ΔABC - scale factor = 2

Part b: For ΔDEF -

Length DF = 2 units

Length D'F' = 1  units

D'F' = 1/2 DF

Hence, For ΔDEF - scale factor = 1/2

Part c: For ΔGHJ

Length GH = 3 units

Length G'H' = 1  units

G'H' = 1/3 GH

Hence,  For ΔGHJ - scale factor = 1/3

Part d: For ΔKML -

The time when the two friends will meet is 8:20 am.

We can start by finding the combined speed at which the two friends are approaching each other. This can be found by adding their individual speeds:

0.2 miles/minute + 0.15 miles/minute = 0.35 miles/minute

This means that the friends are approaching each other at a combined speed of 0.35 miles/minute.

To find out how long it will take for the friends to meet, we can use the formula:

time = distance / speed

In this case, the distance is 7 miles (since they are 7 miles apart) and the combined speed is 0.35 miles/minute. So we can solve for time as follows:

time = 7 miles / 0.35 miles/minute = 20 minutes

Therefore, it will take the two friends 20 minutes to meet each other while biking towards each other.

Since they started biking at 8am and it took them 20 minutes to meet, they will meet at 8:20am.

Therefore , the solution of the given problem of ratio comes out to be the Udderly Delicious Cheese Factory needs 550 gallons of milk in total.

A group comprising values both variable "a" and "" that seem to be equal is found using the straightforward formula "a / b," whenever "b" might be a greater number than zero. A ratio is created by combining two ratios. The ratio , fraction could have been 1:1 if there were just one guy and three women. There are 1/4 men and 3/4 women in the group.

Here,

For cheddar cheese, multiply the quantity of blocks by 200 and the amount of milk consumed by each block by 5.

200 blocks of cheddar cheese divided by 5 quarts per block equals a total of 1000 quarts.

For Swiss cheese, the formula is as follows: 200 blocks of Swiss cheese, or 6 quarts of milk per block.

200 blocks of Swiss cheese divided by 6 quarts per block equals 1200 quarts of milk in total.

Total milk used equals the sum of the milk required to make cheddar cheese and the milk used to make Swiss cheese, or 1000 quarts plus 1200 quarts, or 2200 quarts.

We can convert quarts to gallons by dividing by 4 because there are 4 quarts in a gallon.

= 1000 quarts + 1200 quarts

= 2200 quarts

We can convert quarts to gallons by dividing by 4 because there are 4 quarts in a gallon.

=> Total gallons of milk used = 2200 quarts / 4 quarts/gallon = 550 gallons

Thus, to make 200 blocks of cheddar cheese and 200 blocks of Swiss cheese each day,

the Udderly Delicious Cheese Factory needs 550 gallons of milk in total.

The amount of interest that Baron Blakk would receive in total after eight years would be 6, 118. 03 krona

To find the interest that Baron Blakk received in eight years of savings, we first need to find the future value of the savings. We can do this with the Future value of annuity due formula as this is an annuity and it is an Annuity due as it is paid at the beginning of the year.

The total value after eight years is:

= Amount saved x ( Future value of annuity, interest, number of years)

= 7, 000 x 8. 87

= 62, 118.03 Krona

The interest earned is:

Answer:

  (c)  -2 × [B1] + [B2] ⇒ [C2]

Step-by-step explanation:

Given three systems of equations, you want to know the operations that transform one system to the next.

Equation B2 is unchanged from equation A2, eliminating choices B and C.

Equation B1 is not a simple multiple of equation A1, eliminating choice A.

Knowing the answer is choice D, we need to find the multiplier k of equation A2 that is being added to A1. We can find that using the x-coefficients:

  k(-3) +5 = -4

  -3k = -9 . . . . . subtract 5

  k = 3 . . . . . . . divide by -3

Then we have ...

  3 × [A2] + [A1] ⇒ [B1] . . . . . . . choice D

Using the same tactics as above, we see that [C1] is unchanged from [B1], eliminating choices A and D.

[C2] is not a simple multiple of [B2], eliminating choice B.

Using the y-coefficient to find k, we have ...

  k(1) +2 = 0

  k = -2 . . . . . . . . subtract 2

Then we have ...

  -2 × [B1] + [B2] ⇒ [C2] . . . . . . . . choice C

The probability that a randomly selected gas station customer on that day did not purchase gasoline is 10/27.

We know that, the probability of any event is the ratio of the number of favorable case to that event to the total number of cases.

The total number of customers in that Gas Station on that day = 135

According to the data table,

Number of customers did not purchase gas but purchased beverage = 35

Number of customers neither purchase gas nor beverage = 15

So total number of customers did not purchase gas = 35 + 15 = 50

Here number of favorable cases = 50

So the probability that a randomly selected gas station customer on that day did not purchase gasoline = 50/135 = 10/27.

To rewrite the equation of the circle in graphing form, we need to complete the square for both the x and y terms.

x² + 6x + y² - 4y = -9

Step 1: Move the constant term to the right side of the equation.

x² + 6x + y² - 4y + 9 = 0

Step 2: Group the x terms and the y terms separately.

(x² + 6x) + (y² - 4y) + 9 = 0

Step 3: Complete the square for the x terms. To do this, take half of the coefficient of x (which is 6), square it, and add and subtract it inside the parentheses.

(x² + 6x + 9 - 9) + (y² - 4y) + 9 = 0

(x + 3)² - 9 + (y² - 4y) + 9 = 0

(x + 3)² + (y² - 4y) = 0

Step 4: Complete the square for the y terms. To do this, take half of the coefficient of y (which is -4), square it, and add and subtract it inside the parentheses.

(x + 3)² + (y² - 4y + 4 - 4) = 0

(x + 3)² + (y - 2)² - 4 = 0

Step 5: Move the constant term to the right side of the equation.

(x + 3)² + (y - 2)² = 4

The equation is now in graphing form, which is:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

Comparing the equation to the graphing form, we see that the center of the circle is (-3, 2) and the radius is 2. Thus, the graph of the circle is centered at (-3, 2) with a radius of 2.

As x approaches 2 from both sides, the values of f(x) do not approach a single value, and f(x) does not have a limit. The answer is option (d).

The calculus concept known as the limit of a function describes how a function behaves when the input variable approaches a particular value.

The phrase "lim f(x) as x approaches a" (or "limit of a function f(x) as x approaches a") describes what occurs to the output of the function when x approaches a value without actually reaching a.

The limit can be expressed in terms of two-sided, left-sided, or right-sided limits, depending on whether x approaches a from both sides, the left, or the right.

We must look at the values of f(x) as x approaches 2 in order to determine lim f(x) as x approaches 2.

Looking at the table, we can see that the values of f(x) rise from 3.99 to 4 as x approaches 2 from the left (that is, as x approaches 2 while remaining smaller than 2). The values of f(x) decline from -5 to -5.01 as x moves towards 2 from the right (that is, as x approaches 2 but staysgreater than 2).

The limit of f(x) as x approaches 2 does not exist because the values of f(x) do not approach a single integer as x approaches 2 from both sides.

The team that has the largest overall size hat for their players is the Falcons; they have a larger mean value of about 22 inches

In order to determine the average hat size per team, it is necessary to sum up each player's measurements and divide by the total number of players.

For the Pelicans: The combined sum equals 344.5, which results from adding up values such as 21.5, 25, 22, 24, and so on. With a team membership of 15 people, their mean measures out to approximately 22.97 inches.

The Falcon's equivalent calculation yields a total of 330 attained from summing head sizes, including those measuring 20, 23.5, 21, etc., with an equal number of members, coming close to an average measure of 22 inches thick.

Answer: There is an approximate 10.7% probability that it will snow on Sunday, making it the day with the lowest likelihood of snow.

Step-by-step explanation: Snow is highly likely on Friday with an 80% probability. The likelihood of no snowfall occurring on Friday is 20%, which can be calculated by subtracting 0.8 (or 80%) from 1.

There is a high probability of snowfall on Saturday with a 7 in 9 likelihood. In simpler terms, the probability can be reduced to 7 out of 9 or around 0.78. The likelihood of snowfall on Saturday is 78%, therefore the chance of no snow on that day is 22% which is equivalent to 1 minus 0.78.

There is a high likelihood of snow on Sunday with a probability of 75 out of 100 or 14 out of 19. It is possible to reduce this to a likelihood of 0.7514, or about 0.107. The likelihood of Sunday not having snow is equivalent to subtracting 0.107 from 1, resulting in a 0.893 or 89.3% probability.

The number of tellers that should be used if the aim is to keep the mean queuing time to less than 5 minutes is 3.

To determine the number of tellers follow these steps:

1. Arrival rate (λ) = 18 customers per hour
2. Mean service time (μ) = 10 minutes per customer = 1/6 customer per minute
3. Lobby capacity = 15 customers
4. Target mean queuing time = 5 minutes

Now, calculate the service rate and find the number of tellers needed to achieve the target mean queueing time.

Step 1: Convert arrival rate to customers per minute: λ = 18/60 = 0.3 customers per minute
Step 2: Calculate the service rate per teller: 1/μ = 1/(1/6) = 6 customers per hour = 0.1 customers per minute
Step 3: Determine the number of tellers (n) needed to achieve the target queuing time:

Using the formula:
n > λ / (μ * (Wq_target + 1/μ))

Here, Wq_target is the target mean queuing time in minutes.
n > 0.3 / (0.1 * (5/60 + 1/(6/60)))

After solving the inequality, we get:
n > 2.4

Since the number of tellers must be a whole number, therefore, at least 3 tellers should be used in the queueing model of the bank to keep the mean queueing time to less than 5 minutes.

When you have found the lowest and highest x-values, look at their dots. If it is shaded, then the answer would contain a less than sign between the number and variable. If it shaded, then it would contain a less than or equal to sign.

Both of the dots with the lowest and highest values are shaded. And the lowest and highest values are -4 and 4 respectively.

Therefore, the answer is D.
