Using mathematical operations we can conclude that the cost per quart of yogurt is $1.29.
What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands. The rules that specify the order in which we should solve an expression involving multiple operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, and Addition Subtraction (from left to right).So, the cost per quart:
The 4-pint carton of yogurt costs $5.16.Meaning that in the carton there are 4 quarts of yogurt.Cost per quart:
= 5.16/4= $1.29Therefore, using mathematical operations we can conclude that the cost per quart of yogurt is $1.29.

In Savannah's World Religions class Quizzes are worth 15% of the final grade, Exams are worth 55%, Projects are worth 25%, and Attendance is worth 5%.
At mid-semester Savannah scored 118 out of 150 points on quizzes, 73, 89, and 97 on the first three exams,each worth 100 points. She got extra credit on her project with a score of 28 out of 25 possible points, and she had perfect attendance to class. Compute Savannah's grade percentage in the class so far.
Savannah's grade percentage in the class so far is 92.28%.
What is the grade percentage?
Percentage is a measure of frequency that is used in mathematics. The sign that represents percentage is %. In order to convert a number to percentage, multiply the fraction of that amount by 100 or by the given percentage.
Savannah's grade percentage can be determined by adding her percentage score in each component that makes up the total grade.
Percentage score in quizzes = (score obtained / maximum score) x percentage allocated to quizzes
(118 / 150) x 15% = 11.80%
Percentage score in the three exams = (average of the three scores / maximum score) / percentage allocated to exams
Average of the three scores = (73+ 89 + 97) / 3 = 86.33
(86.33 / 100) x 55% = 47.48%
Percentage score in the project = (score in the project / maximum points) x percentage allocated to project
(28 / 25) x 25% = 28%
Percentage score in attendance = 5%
Total grade percentage so far: 5% + 28% + 47.48% + 11.80% = 92.28%

The son mowed most of the lawn
7/20 of the lawn still needs to be mowed
Explanations:Size of the lawn mowed by Miss Jones = 1/4
Size of the lawn mowed by her son = 2/5
To know who mowed the most lawn, find the LCM of the denominators
The LCM of 4and 5 = 20
Make the denominators of both fractions to be 20
Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20
Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20

What is the area of a rectangle?The area of a rectangle is the space occupied by the rectangle inside its perimeter. A rectangle's area is calculated by multiplying its length by its width.
Given:
Length of rectangle = 20 cm
Width of rectangle= x cm
Area of rectangle = length × width
= 20x cm²
The dimensions of the smaller rectangle cut out of it are,
Length = 16cm
Width = x-3
Area of the smaller rectangle = length × width
= 16(x - 3) cm²
The area of the shaded portion will be equal to the difference between both areas which is given as 80 square centimeters.
20x - 16(x-3) = 80
Now, we need to solve this equation to obtain the value of x.
20x - 16x + 48 = 80
4x = 80 - 48
4x = 32
x = 32/4

Which values are in the solution set to this inequality? 3 x 4 < 9 and − x 6 ≥ − 3 x = 4 x = 11 x = 18 x = 12 x = 15
The value of x in the solution set is x = 4
How to determine the values in the solution setThe system of inequalities is given as
3x + 4 < 9
-x + 6 ≥ -3
The first step is to solve for x in both inequalities in the system of inequalities
So, we have
3x + 4 < 9
3x < 5
Divide by 3
x < 5/3
Also, we have
-x + 6 ≥ -3
-x ≥ -9
Divide by -1
x ≤ 9
So, we have
x < 5/3 and x ≤ 9
x ≤ 9 is a superset of x < 5/3
So, we have
x ≤ 9
This means that the values of x do not exceed 9

Using the continuity concept, it is found that the function is continuous on the following interval:
C. (0, 1).
What is the continuity concept?A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
In the context of this problem, the numeric values are especially relevant, as the function not continuous at the zeros of the denominator.
The denominator of the function is given as follows:
(x² - 2)(x + 0.4).
Hence the discontinuity points are:
x² - 2 = 0 -> x = -1.41 and x = 1.41.x + 0.4 = 0 -> x = -0.4.Hence the only interval in which the function is continuous over the entire interval is given by option C.

A bag contains 7 red balls and 3 white balls. Andrew, Betsy, Cam and Doug, in that order are going to randomly pick a ball out of the bag and not replace it. The first person to draw a white ball wins $160. What is the probability that Doug will win the S160?
ANSWER
3/7 (the correct option is not there)
EXPLANATION
There are 7 red balls and 3 white balls in the bag.
To find the probability of Doug being the first to draw the white ball, we have to assume that Andrew, Betsy and Cam all draw red balls.
There are a total of 10 balls there.
After Andrew Betsy and Doug pick their balls, there will be 7 balls left, that is:
4 red balls and 3 white balls.
Ther probaility of Doug picking the white ball will therefore be the number of white balls divided by the total number of balls.
That is:
P(Doug) = 3/7
That is the probability that Doug will win the $160.

Her monthly payment will be $103.29.
Define simple interest.Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest. Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. Because simple interest keeps total interest payments lower than compound interest, it is better for borrowers. Simple interest is used in the monthly amortization of auto loans and retailer instalment loans. As the loan balance decreases with each monthly payment, so does the interest.
Given Data
Principal = $939
Time = 12 months
Rate = 11%
Simple interest = P(R)(T)
Simple interest = [tex]\frac{939(1)(11)}{100}[/tex]
