There are 56 servings in a 28 pound bag of dog food.
What is Unitary Method ?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Each day Fei yen's dog eat dog food = 8 ounces
Fei yen bought a 28 pound bag of dog food.
And we know that 1 pound = 16 ounces
Then ,the food in ounces
= 28 x 16
= 448 ounces
Now, the number of 8 ounces servings are in a 28 pound bag of dog food
= 448 / 8

A map of a highway has a scale of 2 inches = 33 miles. The length of the highway on the map is 6 inches. There are 11 rest stops equally spaced on the highway, including one at each end. You are making a new map with a scale of 1 inch = 30 miles. How far apart are the rest stops on the new map?
Thus, the required rest stops are approximately 4.09 miles apart on the new map.
What is the scale factor?The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
The total length of the highway in miles can be found by using the scale of the original map. Since 2 inches on the map represent 33 miles in reality, 6 inches on the map represent:
= 6 inches × (33 miles/2 inches) = 99 miles
Since there are 11 equally spaced rest stops along the highway,
= (99 miles)/(11 intervals) = 9 miles per interval
To create the new map with a scale of 1 inch = 30 miles, we need to use a scale factor of (1/2) × (30/33) = 15/33.
Therefore, the distance between each rest stop on the new map can be found by multiplying the distance between rest stops on the old map by the scale factor,
= (9 miles per interval) × (15/33) = 4.09 miles per interval
So, the required rest stops are approximately 4.09 miles apart on the new map.

If all of the diagonals are drawn from a vertex of an n-gon, how many triangles are formed?A) n - 2B) n - 1C) nD) n + 1
The correct answer to the given question about all of the diagonals drawn from a vertex of an n-gon is option b) n-1
If all of the diagonals are drawn from a vertex of an n-gon, the number of triangles formed is equal to the number of non-diagonal sides of the n-gon. To see why, imagine selecting a vertex of the n-gon and drawing all of the diagonals from that vertex. Each diagonal connects that vertex to a non-adjacent vertex of the n-gon, which splits the n-gon into a series of triangles. The total number of triangles formed is equal to the number of non-diagonal sides of the n-gon, because each non-diagonal side forms one triangle with the selected vertex and one of its adjacent vertices. An n-gon has n sides, so the number of non-diagonal sides is equal to n - 3. This is because each vertex is connected to two adjacent vertices, so there are n - 2 diagonal sides emanating from the selected vertex, and the remaining n - 2 sides are non-diagonal. In addition, there are three sides at the selected vertex that are not counted as non-diagonal sides, so we subtract 3 from n - 2 to get n - 3. Therefore, the answer is (B) n - 1.

A plane is flying at a speed of 175 miles per hour.
The pilot plans on flying at this speed for the next
250 miles, plus or minus 25 miles. Find
the minimum and maximum number of hours th
plane will travel at that speed.
The maximum number of hours is 1.6 hours and the minimum number of hours is 1.6 hours.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Given that, a plane is flying at a speed of 175 miles per hour.
The distance covered by the pilot, d = 250 ± 25 miles
We know that, speed = Distance/Time
The equation for the maximum number of hours is given as;
175 =(250+25)/t
t=275/175
t=1.6 hours
The equation for the minimum number of hours is given as;
175 =(250-25)/t
175=225/t
t=225/175
t=1.3 hours
Therefore, the maximum number of hours is 1.6 hours and the minimum number of hours is 1.6 hours.

Susan bought 2/5 as many boxes of butter cookies as chocolate cookies. She spent $156 altogether. Each box of butter cookies cost $2 less than each box of chocolate cookies. The total cost of the chocolate cookies was $84 more than the total cost of the butter cookies. How many boxes of cookies did Susan buy?
Susan bought 6 boxes of chocolate cookies, and 2/5(6) = 2.4 or 2 boxes of butter cookies.
How to find number of boxes of cookies did Susan buy?Let's call the number of boxes of chocolate cookies that Susan bought "C". Then, she bought 2/5 as many boxes of butter cookies, which is 2/5C.
Let's call the cost of each box of chocolate cookies "x". Then, the cost of each box of butter cookies is x-2, since each box of butter cookies costs $2 less.
We know that the total cost of the chocolate cookies was $84 more than the total cost of the butter cookies. This can be expressed as:
Cx = 2C/5(x-2) + 84
Simplifying this equation, we get:
3/5Cx = 84 + 2/5C(2)
Multiplying both sides by 5/3, we get:
Cx = 140 + 4C/3
We also know that the total cost of all the cookies was $156, which can be expressed as:
Cx(x) + (2/5C)(x-2) = 156
Substituting Cx from the previous equation, we get:
(140 + 4/3C)(C) + (2/5C)(C-2) = 156
Simplifying and solving for C, we get:
C = 6
So Susan bought 6 boxes of chocolate cookies, and 2/5(6) = 2.4 or 2 boxes of butter cookies.

To be able to describe the location of a raw score in the distribution of raw scores c. To make all the transformed scores greater than 0 d. To make it possible to compare scores from two different distributions
For a z-score, We transform a set of raw scores into a set of z-scores because we can compare scores from two different distributions i.e. D.
What exactly is the z-score?
The z-score is a statistical measurement that describes a value's relationship to the mean of a collection of values. The z-score formula is
z = (x - μ)/σ
x = data point
μ = mean
σ = standard deviation
Mean:- The sum of a collection of numbers divided by the total number of numbers in the set is known as the arithmetic mean, sometimes known as the arithmetic average or simply the mean or average. A survey, experiment, or observational research is usually used to create the collection.
Now,
As Z-scores are standardized scores that identify and define each score's exact placement within a distribution. We may conduct meaningful comparisons of z-scores across various samples or groups by converting our data (raw score).

Answer:1024 grid squares
Step-by-step explanation:
Let's call the side length of the original piece of graph paper "x".
Since, side length of the cut out square is then (x-2) because the cut out square has to have an integer number of grid squares, and each side of the square would take up 2 grid squares on the graph paper.
The number of grid squares in the cut out square is then (x-2)^2.
The number of grid squares left on the graph paper is 124, so we have:
x^2 - (x-2)^2 = 124
Expanding the right side:
x^2 - x^2 + 4x - 4 = 124
Simplifying:
4x = 128
therefore:
x = 32
therefore original graph paper contains 32 grids i.e 32^2 = 1024
Answer:
any of {128, 133, 140, 160, 224, 320, 380, 700, 1024}
1024 if the original grid was square
Step-by-step explanation:
You want to know how many grid squares are on a piece of graph paper if a square number of grid squares can be cut from it to leave 124 grid squares.
Square graphIf the graph is square to begin with, a square of x² can be removed from its size (x+a)² to leave 124 squares. That is ...
(x +a)² -x² = 124
(a)(2x+a) = 124
The factor pairs of 124 are ...
124 = 1·124 = 2·62 = 4·31
Of these, only 2 and 62 differ by an even number, so we have a=2 and x=30.
The graph paper could be 32 units square originally, having 1024 grid squares.
Rectangular graphThere is nothing in the problem statement that requires the original graph paper be square. If it is not necessarily square, there are 13 possible shapes it could be. Those have 9 different possibilities for numbers of grid squares.
The graph paper could have originally had this number of grid squares:
128 = 4×32 = 8×16. The square removed is 2².133 = 7×19. The square removed is 3².140 = 5×28 = 7×20 = 10×14. The square removed is 4².160 = 8×20 = 10×16. The square removed is 6².224 = 14×16. The square removed is 10².320 = 16×20. The square removed is 14².380 = 19×20. The square removed is 16².700 = 25×28. The square removed is 24².1024 = 32×32. The square removed is 30². . . . . discussed above__

Mckenna spends 7/4 hours mopping the floors and 27/8 hours mowing and weeding the yard how many hours does she needs to spend on her chors
The total amount of time McKenna spends on her chores is 41/8 hours, or approximately 5.125 hours.
To find the total amount of time McKenna spends on her chores, we need to add up the time she spends mopping the floors and mowing and weeding the yard.
First, let's convert both the time spent mopping the floors and mowing and weeding the yard to a common denominator. The least common multiple of 4 and 8 is 8, so we can convert 7/4 hours to
7/4 * 2/2 = 7/2 hours.
Next, we can add the time spent on each chore:
7/2 hours + 27/8 hours = (14 + 27)/8 hours = 41/8 hours.
So, the total amount of time McKenna spends on her chores is 41/8 hours, or approximately 5.125 hours.
It is important to note that this calculation assumes that the time spent on each chore is a continuous amount of time, rather than broken up into smaller increments throughout the day.

there are 14 people in an office with 5 different phone lines. if all the lines begin to ring at once, how many groups of 5 people can answer these lines?
There are 2002 groups of 5 people that can answer the 5 phone lines.
This is a combination problem, because we want to choose groups of 5 people from a group of 14, and the order in which we choose the people does not matter.
The formula for the number of combinations of n objects taken r at a time is:
C(n,r) = n! / (r! * (n-r)!)
In this case, we want to choose 5 people out of a group of 14, so we can plug those values into the formula:
C(14,5) = 14! / (5! * (14-5)!)
Simplifying the factorial terms:
C(14,5) = (1413121110) / (54321)
C(14,5) = 2002
