The percentage decrease in the number of students will be 6.6%. The correct option is B.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that last year, Springfield Middle School had 620 students. This year, it has 582 students.
The percentage decrease will be calculated as:-
Percentage decrease = ( 620 - 582 ) / 582
Percentage decrease = ( 38 / 582) = 0.0652
Percentage decrease = 0.0652 x 100 = 6.52% ≅ 6.6%
Therefore, the percentage decrease in the number of students will be 6.6%. The correct option is B.

3 sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sisters age. what is the age of the youngest child.
Step-by-step explanation:
Let n be the age of the youngest sister. Since the ages are consecutive odd integers, the next sister's age is n+2, and the oldest sister is n+4. the following equation represents the relationship between the girls' ages.
n + 3(n + 4) = 5(n + 2) - 5
n + 3n + 12 = 5n + 10 - 5
4n + 12 = 5n +5
-4n -5 -4n -5
7 = n
so the sisters are 7, 9, and 11
The age of the youngest child 7 years.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Since, the ages are consecutive odd integers,
So, Let x be the age of the youngest sister.
The next sister's age is x + 2,
And, the oldest sister is x + 4.
Hence, The following equation represents the relationship between the girls ages.
x + 3(x + 4) = 5(x + 2) - 5
x + 3x + 12 = 5x + 10 - 5
4x + 12 = 5x + 5
12 - 5 = 5x - 4x
x = 7
So, The age of the youngest child 7 years.

Answer: [tex]\frac{5}{6}x-10[/tex]
==============================
Work Shown:
[tex]\left(\frac{1}{3}x-8\right)+\left(\frac{1}{2}x-2\right)\\\\\frac{1}{3}x-8+\frac{1}{2}x-2\\\\\left(\frac{1}{3}x+\frac{1}{2}x\right)+(-8-2)\\\\\left(\frac{1}{3}+\frac{1}{2}\right)x-10\\\\\left(\frac{2}{6}+\frac{3}{6}\right)x-10\\\\\frac{2+3}{6}x-10\\\\\frac{5}{6}x-10\\\\[/tex]
Answer:
[tex]\frac{5}{6}[/tex]x-10
Step-by-step explanation:
([tex]\frac{1}{3}[/tex]x-8)+([tex]\frac{1}{2}[/tex]x-2) = [tex]\frac{1}{3}[/tex]x-8+[tex]\frac{1}{2}[/tex]x-2
[tex]\frac{1}{3}[/tex]x-8+[tex]\frac{1}{2}[/tex]x-2 = [tex]\frac{1}{3}[/tex]x+[tex]\frac{1}{2}[/tex]x-10
If you -8 then -2, you are subtracting 10 from the equation in total.
[tex]\frac{1}{3}[/tex]x+[tex]\frac{1}{2}[/tex]x-10 = [tex]\frac{2}{6}[/tex]x+[tex]\frac{3}{6}[/tex]x-10
To make the denominator the same, I will multiply the first fraction by 2 and the second fraction by 3 so that their denominators are 6.
[tex]\frac{2}{6}[/tex]x+[tex]\frac{3}{6}[/tex]x-10 = [tex]\frac{5}{6}[/tex]x-10
Once the denominators are the same, you can do the working for the numerators directly (2+3=5) and keep the denominator the same.

The ratio of the length to the width of a rectangular field is 3 to 2. If the field is 150 yards long, how wide is the field?
Answer:
The field is 100 yards wide.
Step-by-step explanation:
Given that the relationship between the length and width of the rectangular field is 3 to 2, and that said field is 150 yards long, the following calculation must be performed to determine its width:
((150/3) x 2) = X
50 x 2 = X
100 = X
Thus, the common largest divisor between both numbers is obtained, and the relationship from 3 to 2 is established based on said number. Therefore, the rectangular field is 100 yards wide by 150 yards long.

At a given time, the length, L, of the shadow of an object varies directly
as the height of the object, H. If the shadow is 27 ft when the height of
the object is 12 ft, what is the height of the object if the shadow is 18 ft?
Answer:
8 ft
Step-by-step explanation:
Use the direct variation equation, y = kx, where k is a constant.
Change the equation to fit the variables: L = kH
Plug in the given length of the shadow and the height of the object, then solve for k:
L = kH
27 = k(12)
2.25 = k
So, the equation is L = 2.25H
Then, plug in 18 as L, and solve for H:
L = 2.25H
18 = 2.25H
8 = H
So, when the shadow is 18 feet, the height of the object is 8 ft
. Isabella buys a 1.75 litre carton of apple juice. What is the largest number of 200 millilitre glasses that she can have from the carton?
Answer:
The largest number of glasses of juice Isabella can have from the carton is 8.
Step-by-step explanation:
Ratios
Knowing the total capacity of the carton of apple juice Ct, and the capacity of each glass Co, we can calculate how many glasses can be taken from the carton by finding the ratio:
[tex]\displaystyle n=\frac{Ct}{Co}[/tex]
There are 1,000 milliliters in one liter, thus the carton has a capacity of
C t= 1.75*1,000 = 1,750 milliliters
Thus,
[tex]\displaystyle n=\frac{1,750}{200}[/tex]
n=8.75
Since we cannot have 8.75 glasses, we round to the previous integer, then:
The largest number of glasses of juice Isabella can have from the carton is 8.
The cost for a company to produce a part for d days is represented by the function
f(d) = 325d +8,795.
What does the value 8,795 represent in this situation?
Options: each day,the total cost decreases by $8795 or each day the total cost increases by 8795 or the initial cost is 8795 or the total cost to produce a part for d days is 8795...plz help
Answer:
Hi,
The equation of a linear function has the following format:
[tex]y = mx + b[/tex]
Where represents the value of for when is equal to zero.
Therefore, 8795 can be considered the initial value for production.
Step-by-step explanation:
The graph of a linear function is the same as the example below:
As noted in the figure, the value of [tex]b[/tex] provides the value of [tex]y[/tex] when [tex]x[/tex] is null. This is also called the linear coefficient of the line (or intercept)
The value of [tex]m[/tex] represents the rate of change of the function and is linked to the slope of the line.
Any questions just ask in the comments.
Since the equation given is f(d) = 325d +8,795, the value that 8,795 represent in this situation is the initial cost.
The given equation in this case is f(d) = 325d +8,795, it should be noted that 8795 is the fixed cost. On the other hand, the expression 325d represents the variable cost.
325d means that the cost will increase each day by that amount. Therefore, the value that 8,795 represents in this situation is the initial cost.

Would Practical math be easier than pre-Calc/trigonometry?
I looked up what practical math was and it seems to be like real-world problems and really long equations, and that is something I struggle with the most because I end up lost a confused but is it as bad as it sounds??? And if it is that bad is it better than pre-calc/trigonometry.
I’m starting my fall semester soon and I would like to know which I should choose

Personally I find them both okay but I think practical math would get quite hard and boring if you dont like it. If u already find it boring, it's probably going to be harder to understand and like. I would recommend doing pre calc as u still do some equations but it's a good mix. it's totally up to u tho good luck! ♡

m and n are negative rational numbers. The product will be negative
TRUE or FALSE
Answer:
The product of two negative rational numbers can not be negative. Hence, the statement that 'the product will be negative' is FALSE.
Step-by-step explanation:
We know that a rational number is a number that can be written in the form p/q, where p and q are integers.
A negative rational number is a number that can be represented as -p/q or
(-1) p/q, where p and q are whole numbers.
It must be not that the product of two negative rational numbers would always be positive.
For example, let suppose m = -5 and n = -7 are two negative rational numbers.
Taking the product of -5 and -7.
= (-5) × (-7)
= 35
Therefore, the product of two negative rational numbers can not be negative. Hence, the statement that 'the product will be negative' is FALSE.

Alex takes a multiple-choice quiz in his Anthropology 100 class. The quiz has 10 questions, each has 4 possible answers, only one of which is correct. Alex did not study for the quiz, so he guesses independently on every question. What is the probability that Alex answers exactly 2 questions correctly
Answer:
The probability is 0.28157
Step-by-step explanation:
The number of answers are 40 answers ( 10 questions and 4 answer each)
The number of correct answers is only 10
So the probability that he answers 2 exactly out of 10 means he correctly selected 2 answers
The probability will be;
10 C 2/ 40 C 10
This mean out of the total 10 correct, he selects 2 and out of the total 40 , he selects 10
The probability of selecting a correct answer is;
1/4 while the probability of selecting a wrong one is 3/4
So probability of selecting 2 correct out of a total 10 will be
10 C 2 (1/4)^2 (3/4)^8
= 0.28157
