Mr.eder’s dog is on a special diet from the vet. The dog is to eat 1/4 kg of food per day. Me.Eder buys a 6 pound bag of dog food. If mr.Eder follows the vet’s diet, how many days will this bag of food last
For 10 days that bag will last when Mr. Eder's buys 6 pound bag of dog food, using kg to pound conversion and simple basic arithmetic operation.
How to convert kg to pound ?
We know that 1 Kg = 2.20 pound.
The dog is to eat 1/4 * 2.20 = 0.55 pound food
Weight of bag brought by him = 6 pound
The basic operations are :
Addition : (+) To get sum of two or more values
e.g. a = 3, b = 5
Addition = 3+5
= 8
Subtraction : (-) The result of subtraction is the “difference”
e.g. Subtraction of a and b = a-b
= 3-5
= -2.
Multiplication : (*) The result of multiplication is the “product”
e.g. Multiplication of a and b = 3*4
= 12
Division : (/) The result of division is the “quotient”
e.g. Division of 4 and 2 is = 4/2
= 2.
so, the number of days bag can be used = 6/0.55
= 10.90
So, the bag can be used for complete 10 days.

C. 72
D. 18
Answer:
72
Step-by-step explanation:
We are told that line AC divides angle BAE in half or "bisects" it. We are also told that line AD divides angle CAE in half as well. Lastly we are giving the value of angle DAE which is 36.
Since line DA split angle CAE in half and we have half of the value, that means that the measure of angle CAE is 36 times 2 which is 72.
72 happens to be our answer for angle BAC because angle BAC is half of the largest angle BAE, which was divided in two by line AC.

Step-by-step explanation:i did the quiz and it is correct
The probability of winning a certain game is 0. 5. If at least 70 percent of the games in a series of n games are won, the player wins a prize. If the possible choices for n are n=10, n=20, and n=100, which value of n should the player choose in order to maximize the probability of winning a prize?.
0.117 Or 11.7% chance of n should the player choose in order to maximize the probability of winning a prize.
What is the binomial theorem on probability?The probability of precisely x successes on n further trials in an experiment with two potential outcomes is referred to as the binomial probability (commonly called a binomial experiment).
When a procedure is performed a certain number of times (for example, in a group of patients), the result for each patient can either be a success or a failure, the binomial distribution model enables us to calculate the probability of witnessing a defined number of "successes."
The probability of winning a prize remains the same for. n = 10 or n=20 or n = 100; the probabilities are the same.
Given that,
p = 0.5, So, q = 1 - 0.5 = 0.5.
If 70% of 'n' games are won then 30% of n games must be lost.
Let n = 10.
Therefore, P ( x = 3) = [tex]^{10}C_3p^7q^3[/tex]
or, P ( x = 3) = [tex]^{10}C_3(0.5)^7(0.5)^3[/tex]
or, P (x = 3) = 120×0.0078×0.125.
or, P (x = 3) = 0.117 Or 11.7% chance.
Now, Changing the value won't have any effect as all the 'n's are multiple of 10 and we'll have same probability.

Domain: x > –6; range: all real numbers are the domain and range of f (x).
What is domain and range ?
The range of values that can be plugged into a function is known as its domain. The x values for a function like f make up this set (x).
The collection of numbers that the function assumes is known as its range. After we enter an x value, the function outputs this sequence of values.
we need to remove all the values of x such that
x + 6 ≤ 0
Solving for x, we get
x ≤ -6
So the only values of x allowed are the ones that make the next inequality true:
x > -6.
Thus we can write the domain as:
D {x | x ∈ R | x > -6}
Where the second part, x ∈ R, is usually ignored, as we assume that x is a real number .

The fraction of a box that can be filled with the leftover textbooks is 10.
What is a fraction?
A fraction is a number that represents a part of a whole or a part of a collection. It is written in the form a/b, where a is called the numerator and b is called the denominator.
To find the fraction of a box that can be filled with the leftover textbooks, we need to first find the total number of textbooks that are leftover. We can do this by subtracting the number of fourth-grade textbooks and the number of fifth-grade textbooks from the total number of textbooks that can fit in a box:
Leftover textbooks = (28 textbooks/box) - (125 textbooks) - (191 textbooks)
= 28 textbooks - 125 textbooks - 191 textbooks
= -288 textbooks
Since there are -288 leftover textbooks, we can fill -288/-28 =-288/-28=10 boxes with the leftover textbooks.
Hence, the fraction of a box that can be filled with the leftover textbooks is therefore 10/1 = 10.

The fraction of a box that can be filled with leftover textbooks is 125/7
What is the fraction?
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
To find the fraction of a box that can be filled with leftover textbooks,
we need to first determine the total number of textbooks that will fit in a box.
Since a box can hold 28 textbooks, and the school has bought 125 Fourth Grade math textbooks and fifth-grade math textbooks,
the total number of textbooks the school has is 125 + 125 = 250 textbooks.
To find the fraction of a box that can be filled with leftover textbooks,
we can divide the total number of leftover textbooks by the total number of textbooks that fit in a box.
Since there are 250 leftover textbooks and a box can hold 28 textbooks, the fraction of a box that can be filled with leftover textbooks is 250/28.
Simplifying this fraction, we get:
250/28 = (250/14)/(28/14) = (250/14)/2 = 125/7
Therefore, the fraction of a box that can be filled with leftover textbooks is 125/7.

Shahina can make apple crumble for 6 people with 550g of apple
How to determine if she can make apple crumble for 6 people?From the question, we have the following parameters that can be used in our computation:
For 8 people it is:
700g of apple, 40g butter, 240g sugar and 180g flour
This means that the grams of apple for 1 person is
Apple unit rate = 700g of apple/Number of people
Substitute the known values in the above equation, so, we have the following representation
Apple unit rate = 700g of apple/8
For 6 people, we have the following equation
Amount = Apple unit rate * Number of people
Substitute the known values in the above equation, so, we have the following representation
Amount = 6 * 700g of apple/8
Evaluate
Amount = 525g of apple
525g of apple is less than 550g of apple

For this lab, you will find the area of an irregularly shaped room with the shape as shown above.
Ask the user to enter the values for sides A, B, C, D, and E and print out the total room area.
Remember the formula for finding the area of a rectangle is length * width and the area of a right triangle is 0.5 * the base * height.
Please note the final area should be in decimal format.
Sample Run
Enter side A: 11
Enter side B: 2
Enter side C: 4
Enter side D: 7
Enter side E: 1
Sample Output
Room Area: 53.5
The python program code is written to find the area of the shape.
What is meant by area?The size of a region on a planar or curved surface is expressed mathematically as area. The term "surface area" refers to the area of an open surface or the perimeter of a three-dimensional object, whereas "plane area" refers to the area of a shape or planar lamina.
The program is given as:
print('Please, enter sides lengths:')
# Getting sides lengths
a, b, c, d, e = map(float, (input('A = '), input('B = '), input('C = '), input('D = '), input('E = ')))
# Finding a rectangle area
rect_area = a * b
# Finding a triangle area
triang_height = (c**2 - (a / 2)**2)**0.5
triang_area = 0.5 * a * triang_height
# Sum area
area = rect_area + triang_area
print('Total room area: %f' % area)
