Answer:

(1)- 1/3  (2)- 2  (3)- 1/2   (4)-  4.

Step-by-step explanation:

We have been given four images and their pre-images and we are asked to find out the factor of dilation.

(1) We have been given a triangle ABC, whose center of dilation is A. In order to find out factor of dilation we will see lengths of two corresponding sides. AB is 6 units long and A'B' is two units long. To map triangle ABC on triangle A'B'C' we have to dilate triangle ABC by a factor of 1/3 as 2 is 1/3 of 6.

Therefore, factor of dilation is 1/3.

(2) Let us find the lengths of two corresponding sides of our image and pre-image. Side ST is 6 units long and S'T' is 12 units long. To map our image of quadrilateral on pre-image we have to dilate our image by a factor of 2 as S'T' is 2 times of ST.

Therefore, factor of dilation is 2.

(3) Side QR is 6 units long and its corresponding side Q'R' is 3 units long. We can see that Q'R' is 1/2 of QR so in order to map our triangle QRS on triangle Q'R'S' we have to dilate our pre-image by a factor of 1/2.

Therefore, our factor of dilation is 1/2.

(4) Length of side AB of our image is 2 units and A'B' is 8 units long. 8 is 4  times 2. To map our pre-image ABC on our image A'B'C' we have to dilate our mage by a factor of 4.

Therefore, factor of dilation is 4.

Solution: The value of temperature is -79.6 degree fahrenheit.

Explanation:

The temperature is given in degree celsius and we have find the temperature in degree  fahrenheit. The formula to  convert the degree celcius in degree fahrenheit is given below,

[tex]F=32+\frac{9}{5} C[/tex]

Where, F is temperature in degree fahrenheit and C is temperature in degree celsius.

Since it is given that the temperature is -62 degree celsius. So put [tex]c=-62[/tex] in the above formula.

[tex]F=32+\frac{9}{5} (-62)[/tex]

[tex]F=32+\frac{(-558)}{5}\\F=32-111.6\\F=79.6[/tex]

Hence the value of temperature is -79.6 degree fahrenheit.

Answer:

part 1- 1/3

part 2- a.n = 22/3+(n-1)1/3

part 3- size 12

Step-by-step explanation:

The common difference of the arithmetic sequence is 0.5 inches.

To find the common difference of the arithmetic sequence, we can use the given information about the shoe sizes and corresponding foot lengths.

Let's denote the common difference by [tex]\( d \)[/tex]. In an arithmetic sequence, the[tex]\( n \)-th[/tex] term is given by [tex]\( a_n = a_1 + (n - 1)d \)[/tex], where [tex]\( a_1 \)[/tex] is the first term.

Given that a women's size 3 fits a foot 8 inches long, we can consider this as the first term of the arithmetic sequence:

[tex]\[ a_1 = 8 \][/tex]

We are also given that a women's size 7 fits a foot[tex]\( 9\frac{1}{3} \)[/tex] inches long. Since this corresponds to the 5th term in the sequence (because [tex]\( 7 - 3 = 4 \)[/tex] and we start counting from 0), we can write:

[tex]\[ a_5 = a_1 + 4d \][/tex]

[tex]\[ a_5 = 8 + 4d \][/tex]

 We know[tex]\( a_5 = 9\frac{1}{3} \),[/tex]which is [tex]\( 9 + \frac{1}{3} \) or \( \frac{28}{3} \)[/tex] inches. Now we can set up the equation:

[tex]\[ 8 + 4d = \frac{28}{3} \][/tex]

To solve for [tex]\( d \)[/tex], we first convert[tex]\( \frac{28}{3} \)[/tex] to a decimal or a fraction with a denominator of 1 to match the units of the other terms:

[tex]\[ 8 + 4d = \frac{28}{3} \times \frac{1}{1} \][/tex]

[tex]\[ 8 + 4d = \frac{28}{3} \][/tex]

[tex]\[ 8 + 4d = 9\frac{1}{3} \][/tex]

[tex]\[ 8 + 4d = 9.333... \][/tex]

Now, we solve for[tex]\( d \)[/tex]:

[tex]\[ 4d = 9.333... - 8 \][/tex]

[tex]\[ 4d = 1.333... \][/tex]

[tex]\[ d = \frac{1.333...}{4} \][/tex]

[tex]\[ d = 0.333... \][/tex]

However, we need to express[tex]\( d \)[/tex] in inches, and since [tex]\( \frac{1}{3} \)[/tex] of an inch is [tex]\( 0.333... \)[/tex]inches, we convert it to a fraction that has a denominator of 2 to match the format of the options given:

[tex]\[ d = \frac{1}{3} \times \frac{2}{2} \][/tex]

[tex]\[ d = \frac{2}{6} \][/tex]

[tex]\[ d = \frac{1}{3} \][/tex]

[tex]\[ d = 0.5 \][/tex]

Therefore, the common difference of the arithmetic sequence is[tex]\( 0.5 \)[/tex]inches."

To determine the time needed to layout a full magazine issue, multiply the time taken to layout 1/16 of an issue (3 days) by 16, resulting in 48 days total.

If a magazine can layout 1/16 of an issue in 3 days, then to calculate how many days it takes to layout one entire issue, we simply multiply the number of days it takes to layout 1/16 of the issue by 16.

This is because if 1/16 takes 3 days, then 1/8 (which is twice the amount of 1/16) would take twice as long

(3 days * 2 = 6 days),

and similarly, we can scale up to the full issue (1/1) by multiplying 3 days by 16.

The calculation would be:

Identify the portion of the issue completed: 1/16.

Identify the time taken for this portion: 3 days.

Calculate the time for the whole issue: 3 days * 16 = 48 days.

So, it would take 48 days to layout one full issue.

The width of the rectangle is 6 meters and the length is 7 meters.

To solve this problem, let's assume that the width of the rectangle is represented by w. The length of the rectangle can be written as 2w - 5. The perimeter of a rectangle is given by the formula P = 2l + 2w, where P represents the perimeter, l represents the length, and w represents the width. We are given that the perimeter is 26 meters, so we can set up the equation:
26 = 2(2w - 5) + 2w
Simplifying this equation gives:
26 = 4w - 10 + 2w
Combining like terms:
26 = 6w - 10
Adding 10 to both sides:
36 = 6w
Dividing both sides by 6:
w = 6
Therefore, the width of the rectangle is 6 meters. To find the length, substitute the value of w back into the expression for the length:
l = 2w - 5
l = 2(6) - 5
l = 7
So the dimensions of the rectangle are width = 6 meters and length = 7 meters.

__________A) $20.48______

Step-by-step explanation:

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival

0.75 per ticket. So cost of 18 tickets= 0.75 * 18 = $13.5

Kendall spent $13.50 for tickets . Total spent = $33.50

Total spent = ticket cost + admission cost

33.50 = 13.50 + admission

Admission cost = 33.50 - 13.50 = $20

(a)  y to represent the total cost , x to represent the number of ride tickets.

'b' represents the admission cost

(b)  General form of linear equation is y=mx+b

m = 0.75 and b = admission cost = 20

So equation becomes y = 0.75x + 20

(c) Initially, she has to pay the admission price $20. then 0.75 per ticket.

The value of x changes depends on the number of tickets she wants to buy.

y is the total cost she has to pay for x tickets with admission price

Option 3 is right

z37 is between 2 and 3 standard deviations of the mean.

Step-by-step explanation:

Let X be a random variable which represents the mean number of miles that the employees in a department live from work

X is normal (N(29,3.6)

WE have to find Z score for X

Z =[tex]\frac{x-29}{3.6}[/tex]

=2.22

i.e. 37 is 2.22 std deviations from the mean.

In other words, z37 is between 2 and 3 standard deviations of the mean.

The z-score for z37 is approximately 2.22. This indicates that it lies between 2 and 3 standard deviations of the mean. Hence, the correct statement is: z37 is between 2 and 3 standard deviations of the mean.

To determine which statement is true regarding the z-score for the value z37, we need to calculate the z-score using the given mean and standard deviation.

This means that z37 is approximately 2.22 standard deviations away from the mean. Therefore, the correct statement is:

z37 is between 2 and 3 standard deviations of the mean.

In a normal distribution, about 95 percent of the x values lie within two standard deviations, and about 99.7 percent lie within three standard deviations of the mean.

A has 4 right angles (That's the property of a rectangle).

Green

B has 5 angles that are equal to 108 degrees. If you draw a 2 lines from any vertex you get 3 triangles. The size of the interior angles totals 3 triangles * 180 degrees = 540 degrees.

540/3 = 108.

Each angle in the interior is 108 degrees.

B has 5 angles all equal 108 degrees. All 5 are obtuse.

Final answer:

After Nicole's check for her electric bill was processed, her account was overdrawn. She then made a deposit equal to the overdraft amount, bringing her end-of-day balance to $0.00.

Explanation:

To determine the bank balance that Nicole had at the end of the day, we need to consider the transactions that affected her account. She started with $63.44. After her electric bill check of $186.56 was processed, her account would have been overdrawn by $186.56 - $63.44 = $123.12. To cover this overdraft, Nicole made a deposit equal to the amount her account was overdrawn. Therefore, she deposited $123.12, which brought her balance back to $0.

At the end of the day, Nicole's bank balance was $0.00.
