Answer: Omar can make 14 whole dumplings.
Step-by-step explanation: Make 2 3/4 an improper fraction. To do this, multiply 2 by the denominator, 4. From this, you get 8. Then add 8 to the numerator, which is 3, and you get 11. Keep the denominator and you'll have 11/4.
To divide fractions, you make 3/16 its reciprocal by basically flipping the fraction so that the numerator becomes the denominator and vise versa, making it 16/3. Then multiply 11/4 and 16/3. 11 x 16 is 176; 4 x 3 is 12. The result is 176/12. Simplify by dividing the numerator and denominator by 4. Your resulting answer should be 44/3. Simplify even further by simple division. Your final answer should be 14 2/3. Discard the 2/3 because Omar needs to make whole dumplings. So the answer is 14.
Final answer:
Omar can make 14 whole dumplings with 2 3/4 cups of dough when each dumpling requires 3/16 cups of dough.
Explanation:
The student's question asks how many whole dumplings Omar can make with 2 3/4 cups of dough if each dumpling uses 3/16 cups of dough.
Convert 2 3/4 cups to an improper fraction: 11/4 cups.
Divide the total cups of dough (11/4) by the amount needed for one dumpling (3/16) to find the number of dumplings Omar can make.
Perform the division: (11/4) \/ (3/16) = 11/4 \\* 16/3 = 44/3.
Omar can make 44/3 dumplings, which is 14 whole dumplings with some dough left over.
Omar can make 14 whole dumplings with 2 3/4 cups of dough when each dumpling uses 3/16 cups of dough.

The width of the rectangle is 75% of its length
hat is the area of the rectangle?
19
b. The length of the rectangle is doubled. What percent of the length is the width now? Explain your reasoning.
Because the length is doubled the width of the rectangle is now half of
75% of its length.
And the square is 24 in
The area of the rectangle is 0.75 of the square of the length. When the length is doubled, the width is 37.5 % of the length.
Explanation:The area of a rectangle is calculated by multiplying its length and width. In this case, the width is 75% of the length. So if we denote the length as 'L', then the width would be 0.75 * L. Therefore, area would be L * 0.75L = 0.75 * L^2.
Now, if the length of the rectangle is doubled, the width remains the same, so it becomes 0.75 * 2L. So the width becomes a smaller fraction of the length. We can work out this out as follows: (0.75L / 2L) * 100 = 37.5%.
So, when the length of the rectangle is doubled, the width is 37.5 % of the length.

1. The area of the rectangle is 0.75 times the square of the length.
2. The width is now 75% of the length.
Part 1:
What is the area of the rectangle?
If the width of the rectangle is 75% of its length, then we can express the width as 0.75 * length.
The area of a rectangle is calculated by multiplying the length and width, so the area of the rectangle in this case is:
Area = length * width = length * 0.75 * length = 0.75 * length^2
Therefore, the area of the rectangle is 0.75 times the square of the length.
Part 2:
The length of the rectangle is doubled. What percent of the length is the width now? Explain your reasoning.
If the length of the rectangle is doubled, then the width is now half of 75% of the new length.
To calculate this, we can use the following steps:
Calculate the new length of the rectangle: old_length * 2 = new_length
Calculate 75% of the new length: 0.75 * new_length
Divide the width by the new length to get the percentage: width / new_length
For example, if the old length of the rectangle was 10 cm, then the new length would be 20 cm. 75% of 20 cm is 15 cm. Therefore, the width is now 75% of the length.
Answer: The width is now 75% of the length.

CAN SOMEONE HELP ME WITH REFLECTIONS??
Answer:
(5, 2 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
P(5, - 2 ) → P'(5, - (- 2)) → P'(5, 2 )
Max is trying to prove to his friend that two reflections, one across the x-axis and another across the y-axis, will not result in a reflection across the line y = x for a pre-image in quadrant II. His friend Josiah is trying to prove that a reflection across the x-axis followed by a reflection across the y-axis will result in a reflection across the line y = x for a pre-image in quadrant II. Which student is correct, and which statements below will help him prove his conjecture? Check all that apply
Max is correct.
Josiah is correct.
If one reflects a figure across the x-axis from quadrant II, the image will end up in quadrant III.
If one reflects a figure across the y-axis from quadrant III, the image will end up in quadrant IV.
A figure that is reflected from quadrant II to quadrant IV will be reflected across the line y = x.
If one reflects a figure across the x-axis, the points of the image can be found using the pattern (x, y) (x, –y).
If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) (–x, y).
Taking the result from the first reflection (x, –y) and applying the second mapping rule will result in (–x, –y), not (y, x), which reflecting across the line should give.
Answer:
Max is correct
If one reflects a figure across the x-axis, the points of the image can be found using the pattern (x, y) ⇒ (x, –y).
If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) ⇒ (–x, y).
Taking the result from the first reflection (x, –y) and applying the second mapping rule will result in (–x, –y), not (y, x), which reflecting across the line should give.
Step-by-step explanation:
The answer above pretty well explains it.
The net result of the two reflections will be that any figure will retain its orientation (CW or CCW order of vertices). It is equivalent to a rotation by 180°. The single reflection across the line y=x will reverse the orientation (CW ⇔ CCW). They cannot be equivalent.
Max is correct in stating that two reflections, one across the x-axis and another across the y-axis, will not result in a reflection across the line y = x for a pre-image in quadrant II. Josiah's conjecture is incorrect. Statements that will help Max prove his conjecture include reflecting a figure across the x-axis and the y-axis, and how the coordinates of the image points change in each reflection.
Explanation:Max is correct. When a figure is reflected across the x-axis, the y-coordinate of each point is negated, resulting in an image in a different quadrant. Therefore, reflecting a figure across the x-axis from quadrant II will place the image in quadrant III. Similarly, when a figure is reflected across the y-axis, the x-coordinate of each point is negated, resulting in an image in a different quadrant. Reflecting a figure across the y-axis from quadrant III will place the image in quadrant IV.
A figure that is reflected from quadrant II to quadrant IV will be reflected across the line y = x. However, reflecting a figure across the x-axis followed by a reflection across the y-axis will result in an image that is reflected across the line y = -x, not y = x. Therefore, Josiah's conjecture is incorrect.
The following statements will help Max prove his conjecture:
If one reflects a figure across the x-axis from quadrant II, the image will end up in quadrant III.If one reflects a figure across the y-axis from quadrant III, the image will end up in quadrant IV.If one reflects a figure across the x-axis, the points of the image can be found using the pattern (x, y) → (x, -y).If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) → (-x, y).Therefore, Max's statements are correct and Josiah's conjecture is incorrect.

Step-by-step explanation:
A lake near the Arctic Circle is covered by a 2 meters thick sheet of ice during the cold winter months.
At the warm air of spring gradually melts the ice thickness gradually.
Therefore, the equation that models the situation is S = 2 - bW ....... (1), where S is the remaining thickness of the ice sheet and W is the number of weeks passed and b is the rate of decrease of ice sheet thickness with respect to the number of weeks.
Now, putting W = 3 weeks and S = 1.25 meters in the equation (1) we get,

7. Nick’s youth group has 20 regular students that attend weekly get togethers. They saved up enough money for each person to go swimming 10 times each with the daily pay plan. After they saved that amount, they found out they can use the early pay plan and save money. They plan to donate their savings to the church since it’s in need of a new sound system. How much money will they be able to donate with the savings from all 20 youth? (Please show all your work for full credit)
WILL GIVE BRILIEST
Answer:
If each youth saves $10 daily, their weekly savings would be $1400. So they donated $1400 to the church.
Step-by-step explanation:
Let the daily pay plan for each youth be $y
Daily pay plan for 20 youth = $20y
Weekly pay plan = 7×20y = $140y
Assuming each youth saves $10 daily
Daily savings for 20 youth = 20×$10= $200
Weekly savings for 20 youth = 7×$200= $1400
If they used the early pay plan ($140y) to go swimming, they saved $1400 which they donated to the church.
Answer:
$375 saved or roughly 33%.
Step-by-step explanation:
With daily plan;
(15)4.00 = 60.00
(25)60.00 = $1,500.00
If the youth group saved up enough for each of them to swim 15 times and 25 students are attending, they originally had $1,500.00 saved for the trip.
With early pay;
(25)45.00 = $1,125.00
1,500.00 - 1,125.00 = $375 saved or roughly 33%.

Answer:
y = 5/2x + 5
Step-by-step explanation:
Your b value is the place where the line crosses the y-axis. So, we can tell right away the b value in the equation is 5.
I'll use negative 2 as the point to find the slope. You go down 5, so we have -5, and go left 2, so -2. 2 negatives make a positive, so the slope is 5/2.

a cafeteria worker is wondering how student lunch prices at a high school have changed over time. she researches lunch prices for the years 2000 through 2015 and plots the data in a scatter plot. the best-fit line for the data has the equation y=0.057 x + 1.150, where x is the number of years since 2000 and y is the student lunch price, in dollars.
determine whether each statement below is true ot false based on the question of the line best fit. select true or false for each question.
the student lunch price was generally increasing between 2000 and 2015.
the student lunch price was changed by approximately 5.7 cents a year.
the student price in 2015 was approximately $1.15.
Answer:
True false true
Step-by-step explanation:
TRUE, the student lunch price was generally increasing between 2000 and 2015 as the equation [tex]y=0.057x+1.150[/tex] is a linearly increasing function.
TRUE, the student lunch price was changed by approximately [tex]5.7\rm cents[/tex] a year.
FALSE, the student price in 2015 was approximately $1.15.
The best-fit line for the data has the equation [tex]y=0.057x+1.150[/tex] , where [tex]x[/tex] is the number of years since 2000 and [tex]y[/tex] is the student lunch price, in dollars.
So, it can be seen here from the best-fit line equation that it is a linearly increasing function so, the student lunch price was generally increasing between 2000 and 2015.
Now, differentiating the given best-fit line for the data has the equation [tex]y=0.057x+1.150[/tex] with respect to [tex]x[/tex] to determine the approximated change of the lunch price per year
[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(0.057x+1.150)\\\dfrac{dy}{dx}=\$0.057\\\dfrac{dy}{dx}=5.7\rm cents[/tex]
And, [tex]2015[/tex] is [tex]15[/tex] years from the year [tex]2000[/tex] so, substitute the value of the parameter [tex]x=15[/tex] in the best-fit line equation, we get
[tex]y=0.057\times 15 +1.150\\y=0.855+1.150\\y=2.005[/tex]
So, the lunch price in 2015 was approximately [tex]\$2.005[/tex].
Hence, the first two statements are TRUE while the last statement is FALSE.

x - 2y = -6
x - y = 12
Answer:
x = 30, y = 18
Step-by-step explanation:
Given the 2 equations
x - 2y = - 6 → (1)
x - y = 12 → (2)
Subtracting (2) from (1) term by term will eliminate the term in x
||(x - x) + (- 2y - (- y)) = (- 6 - 12), that is
- y = - 18 ( multiply both sides by - 1 )
y = 18
Substitute y = 18 into either of the 2 equations for value of x
Substituting in (2)
x - 18 = 12 ( add 18 to both sides )
x = 30
Answer: (30,18)
x - 2y = -6
x - y = 12
x - y = 12
- y = 12 - x
y = -12 + x
x - 2y = -6
x = -6 + 2*y
y = -12 + (-6+ 2*y)
y = -12 - 6 + 2*y
y - 2*y = -18
-y = -18
y = 18
y = -12 + x
18 = -12 + x
-x = -12 - 18
x = 12 + 18
x = 30

You are choosing between two long-distance telephone plans. Plan A has a monthly fee of $40.00 with a charge of $0.05 per minute for all long-distance calls. Plan B has a monthly fee of $15.00 with a
charge of $0.10 per minute for all long-distance calls. Complete parts a and b.
a. For how many minutes of long-distance calls will the costs for the two plans be the same?
minutes
Answer:
The number of minutes of call for long distance is 500 minutes .
Step-by-step explanation:
Given as :
The two different long distance telephones plans are plan A and Plan B
Plan A
monthly fee = $40.00
The charge per minute = $0.05
Plan B
monthly fee = $15.00
The charge per minute = $0.10
now, for both plans
Let The number of minutes of call for long distance = n minutes
So, According to question
∵ The both plans to be same
Monthly fee for plan A + The charge per minute × number of minutes of call for long distance for A = Monthly fee for plan B + The charge per minute × number of minutes of call for long distance calls for B
i.e $40.00 + $0.05 × n = $15.00 + $0.10 × n
Or, $40.00 - $15.00 = $0.10 × n - $0.05 × n
Or, $25 = $0.05 × n
∴ n = [tex]\dfrac{25}{0.05}[/tex]
I.e n = 500 minutes
So, The number of calls minutes = n = 500 minutes
Hence, The number of minutes of call for long distance is 500 minutes . Answer

[tex]4^{x+2} = 12[/tex]for x, we can use the change of base formula log base b of y equals log y over log b. Let's solve it step by step:
Take the logarithm of both sides of the equation using any base (let's use base 10 for this example): [tex]log (4^{x+2})[/tex] = log 12Apply the power rule of logarithms: (x+2) * log 4 = log 12Divide both sides by log 4: x+2 = log 12 / log 4Subtract 2 from both sides to isolate x: x = log 12 / log 4 - 2Use a calculator to evaluate the right side of the equation: x ≈ -0.086Therefore, the solution to the equation
[tex]4^{x+2} = 12[/tex]is approximately x = -0.086.
In a shop, apples cost 27p each and oranges cost 36p each.
Muhammed bought some apples and oranges in the shop. He paid £1.53.
Work out how many apples and how many oranges Muhammed bought.
HELP!
Answer:
The number of apple bought is 3
The number of orange bought is 2
Step-by-step explanation:
Given as :
The price of each apple = 27 p = 27 × 0.01 pound = 0.27 pound
The price of each orange = 36 p = 36 × 0.01 pound = 0.36 pound
The Total money paid for the fruits = 1.53 pounds
Let The Total number of apple bought = a
And The Total number of orange bought = o
Now, According to question
Total money paid for the fruits = Total number of apple bought × price of each apple + Total number of orange bought × price of each orange
Or, 0.27 a + 0.36 o = 1.53 ......A
Here The Total quantity of fruits bought is not given, so apply hit and trial method to calculate total number of each fruit
Let The a = 1 and o = 1
So, 0.27 × 1 + 0.36 × 1 = 1.53
∴ 0.63 ≠ 1.53
Again
Put a = 2 , o = 2
So, 0.27 × 2 + 0.36 × 2 = 1.53
∴ 1.26 ≠ 1.53
Again
Put a = 3 , o = 3
So, 0.27 × 3 + 0.36 × 3 = 1.53
∴ 1.89 ≠ 1.53
Now, Let a = 3 , o = 2
So, 0.27 × 3 + 0.36 × 2 = 1.53
∴ 1.53 = 1.53
so, from hit and trial method , we get the number of apple = a = 3
And he number of orange = o = 2
Hence, The number of apple bought is 3
And The number of orange bought is 2 . Answer

The required wavelength of the yellow light is [tex]5.8\times10^{-7}[/tex] m
The correct option is (A).
Wavelength:
The wavelength can be calculated when frequency and speed of the wave are given as
wavelength [tex]\lambda[/tex] = [tex]\frac{v}{f}[/tex]
where v is the velocity of the wave and f be the frequency of the wave.
How to calculate wavelength?Here we have given that
The frequency f = [tex]5.2 \times10^{14}[/tex] Hz
The speed v = [tex]3 \times10^{8}[/tex] m/s
Therefore substitute into above formula
Wavelength [tex]\lambda[/tex]= [tex]\frac{3\times10^{8}}{5.2\times10^{14}}}[/tex]
Wavelength [tex]\lambda[/tex] = [tex]\frac{3}{5.2}\times10^{8-14}[/tex]
Wavelength [tex]\lambda[/tex] = [tex]0.5769\times10^{-6}[/tex]
Wavelength [tex]\lambda[/tex] = [tex]0.5769\times10^{-6}[/tex]
Wavelength [tex]\lambda[/tex] = [tex]5.769\times10^{-7}[/tex]
Wavelength [tex]\lambda[/tex]= [tex]5.8\times10^{-7}}[/tex] m
Therefore the correct option is (A).

If Laura bought 2.1 pounds of apples is the price per pound of apples greater or less than $1
Answer:
The price per pound of apples is greater than $1.
Step-by-step explanation:
Please consider the complete question:
Three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1 ? how can you tell?
To find the price of apples per pound, we need to divide total amount paid by Laura ($2.88) with total pounds of apples (2.1 pounds) bought.
[tex]\text{Price of apples per pound}=\frac{\$2.88}{2.1}[/tex]
[tex]\text{Price of apples per pound}=\$1.37142857[/tex]
Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.
To find the price per pound of apples, we divide the total cost of the apples by the weight of the apples.
Explanation:To determine whether the price per pound of apples is greater or less than $1, we need to divide the total cost of the apples by the weight of the apples. The question states that Laura bought 2.1 pounds of apples. To find the total cost, we can use the information given in the reference:
10 apples × 50 cents each = $5.00 spent on apples in 2001.
Dividing $5.00 by 2.1 pounds gives us the price per pound of apples Laura bought, which is approximately $2.38. Therefore, the price per pound of apples is greater than $1.
