The correct set of inequalities that model the constraints on the composition of the student body are:
600 ≤ a ≤ 700, 500 ≤ b ≤ 600 and a + b ≤ 1200
What is inequalities?
In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).
The correct set of inequalities that model the constraints on the composition of the student body are:
600 ≤ a ≤ 700 (the number of underclassmen must fall between 600 and 700, inclusive)
500 ≤ b ≤ 600 (the number of upperclassmen must fall between 500 and 600, inclusive)
a + b ≤ 1200 (the total number of students cannot exceed 1200)
Note that the inequalities 600 < a < 700 and 500 < b < 600 are not correct, as they do not take into account the inclusive limits of the ranges for the number of underclassmen and upperclassmen. Also, the inequality a + b > 1200 is not correct, as it contradicts the previous inequality a + b ≤ 1200.

The amount of chalk that is greater is yellow.
Michelle is correct because more than 1/2 the chalk in the bucket is blue.
How to determine which amount of chalk is greater?In order to determine the amount of chalk that is greater between the amount of yellow chalk and amount of green chalk, we would have to find the difference between them as follows;
Difference = 2/6 - 3/12
Difference = (4 - 3)/12
Difference = 1/12 (positive value)
Similarly, we can determine the greater amount of chalk as follows;
2/6 × 2/2 = 4/12
4/12 > 3/12
Total number of chalks = 2/6 + 5/12 + 3/12
Total number of chalks = (4 + 5 + 3)/12
Total number of chalks = 12/12
Total number of yellow and green chalks = 2/6 + 3/12
Total number of yellow and green chalks = (4 + 3)/12
Total number of yellow and green chalks = 7/12 chalks.
1 - 7/12 = 5/12
7/12 - 1/2 = 6/12 (Michelle is correct).

A rectangle has a length of x + 4 cm and a width of 2x − 7 cm.
(a) If the perimeter is 36cm, what is the value of x?
(b) What is the area of this rectangle
Answer:
See below!
Step-by-step explanation:
Given data:Length = x + 4 cm
Width = 2x - 7 cm
Part a)Perimeter:
Sum of all sides of a shape is called perimeter.Perimeter of rectangle = 2(length) + 2(width)Put the given data.
36 = 2(x + 4) + 2(2x - 7)
Distribute36 = 2x + 8 + 4x - 14
Combine like terms36 = 2x + 4x + 8 - 14
36 = 6x - 6
Add 6 to both sides36 + 6 = 6x
42 = 6x
Divide both sides by 642/6 = x
7 = x
OR
x = 7Part b)Area of rectangle = length × widthArea = (x + 4)(2x - 7)
Put x = 7
Area = (7 + 4)(2(7) - 7)
Area = 11(14 - 7)
Area = 11(7)
Area = 77 cm²[tex]\rule[225]{225}{2}[/tex]
Answer: (a) x=7
(b) area of this rectangle = 77[tex]cm^{2}[/tex]
Step-by-step explanation:
(a) the perimeter of a rectangle = 2 * [ l + b ]
36 = 2 * [ (x + 4) + (2x - 7) ]
36 / 2 = x + 4 + 2x - 7
18 = 3x -3
18 + 3 = 3x
21 = 3x
x = 7
(b) the area of a rectangle = l * b
l = x + 4 = 11cm
b = 2x -7 = 7cm
therefore, 11cm * 7cm = 77[tex]cm^{2}[/tex]

Find the minimum or maximum of the function y=x^2-9
I will be finding the minimum of this parabolic function.
The function y = x^2 - 9 is a parabola that opens upwards, since the coefficient of the x^2 term is positive. Therefore, the minimum value of the function occurs at the vertex of the parabola.
To find the x-coordinate of the vertex, we can use the formula -b/2a, where the quadratic function is in the form y = ax^2 + bx + c. In this case, a = 1 and b = 0, so the x-coordinate of the vertex is -b/2a = -0/(2*1) = 0.
To find the corresponding y-coordinate of the vertex, we can substitute x = 0 into the function, which gives y = 0^2 - 9 = -9.
Therefore, the minimum value of the function y = x^2 - 9 is -9, which occurs at x = 0.
~~~Harsha~~~
The minimum point of this function is located at (0, -9).
Step-by-step explanation:1. Determine whether it's a minimum or maximum.So from plain sight we can tell we're looking for a maximum point, because the coefficient of x² is positive, it's 1. If the function was y=-x²-9, we would be looking at a minimum point.
2. About the minimum...The vertex if the exact point where a quadratic or any pair exponent function will start to either decay or increase, therefore, it will be the minimum or maximum point.
Formula for "x" value of vertex: [tex]\sf x_{Vertex} =\dfrac{-b}{2a}[/tex].
In this equation, a and b are coefficients extracted when the formula is expressed on its standard form.
Standard form of a quadratic equation: ax² + bx + c = 0
➔ You need to substitute the "y" by a "0", and the formula should look like this:
[tex]\sf 0=x^2-9[/tex]
➔ Reorganizing...
[tex]\sf x^2-9=0[/tex]
3. Extracting the coefficients.Let's expand the previous expression:
[tex]\sf x^2+0x_{} -9=0[/tex]
The coefficients are:
a= 1, beacuse "x²" is being multiplied by 1, which is implicit.
b= 0, because "x" doesn't really exist on the simplified equation.
c= -9.
4. Calculate the "x" and "y" locations of the vertex.Now let's calculate the "x" position of the vertex using the formula from step 2:
[tex]\sf x_{Vertex} =\dfrac{-b}{2a}=\dfrac{-(0)}{2(1)}=0[/tex]
Now, the "y" value can be obtained just by substituting "x" by 0 on the argument of the function:
[tex]\sf y=(0)^2-9\\ \\y=-9[/tex]
Therefore, the vertex, or minimum point of this function is located at (0, -9).

(4+sqrt -20i)+(5+sqrt -30i)
The sum of the two complex numbers is 9 - √30) + 2√(5)i.
Explain complex numbers
Complex numbers are numbers that consist of a real part and an imaginary part, expressed as a+bi, where a and b are real numbers and i is the imaginary unit. They are used in mathematics to represent solutions to equations that cannot be solved using only real numbers.
According to the given information
To add complex numbers (4+√(-20i)) and (5+√(-30i)), we add their real parts separately and their imaginary parts separately:
Real parts: 4 + 5 = 9
Imaginary parts: √(-20i) + √(-30i)
We can simplify each of the square roots using the fact that:
√(-1) = i
Therefore:
√(-20i) = √(20) * √(i) = 2√(5) * i
√(-30i) = √(30) * √(i) = √30) * i * √(-1) = √(30) * i^2 = -√(30)
So the imaginary parts simplify to:
2√(5)i - √(30)
Putting it all together, we get:
(4+√(-20i)) + (5+√(-30i)) = 9 + (2√(5)i - √(30)) = 9 - √(30) + 2√(5)i
Therefore, the sum of the two complex numbers is 9 - √(30) + 2√(5)i.

Julia measured the high temperature in her town for one week. Using the chart above, find the mean absolute deviation for the high temperatures. Round your answer to the nearest tenth.
Be sure to show your work for finding:
the mean of the set of data
the distance of each number from the mean
the mean absolute deviation
the mean absolute deviation for the high temperatures in Julia's town for the week is 4.9 degrees.
How to solve the question?
To find the mean absolute deviation (MAD) for the high temperatures in Julia's town, we first need to find the mean temperature for the week.
To do this, we add up all the temperatures and divide by the number of temperatures:
(49 + 55 + 42 + 46 + 47 + 42 + 38) ÷ 7 = 43.3
The mean temperature for the week is 43.3 degrees.
Next, we need to find the distance of each temperature from the mean. To do this, we subtract the mean from each temperature:
|49 - 43.3| = 5.7
|55 - 43.3| = 11.7
|42 - 43.3| = 1.3
|46 - 43.3| = 2.7
|47 - 43.3| = 3.7
|42 - 43.3| = 1.3
|38 - 43.3| = 5.3
We take the absolute value of each difference to ensure that the distances are positive.
Now, we find the mean of the distances by adding up all the distances and dividing by the number of temperatures:
(5.7 + 11.7 + 1.3 + 2.7 + 3.7 + 1.3 + 5.3) ÷ 7 = 4.9
Therefore, the mean absolute deviation for the high temperatures in Julia's town for the week is 4.9 degrees.
In conclusion, the mean absolute deviation is a measure of the variability of a set of data. It is calculated by finding the mean of the absolute distances of each data point from the mean. In this case, the MAD is 4.9 degrees, indicating that the temperatures for the week were relatively close to the mean.

For an investment of 26,245, a quarterly statement reports that the account is 26,292. The statement reports that for the same quarter, the rate of return of the investment was - 0.02%. Given the information regarding the investment quarterly activity, does the reported rate of return seem reasonable?
No. The reported return rate appears lower than expected.
Rate of returnsTo determine whether the reported rate of return is reasonable or not, we can calculate the expected rate of return based on the investment amount and the ending value of the account.
First, we need to calculate the total number of quarters that have elapsed between the initial investment and the current quarter. Let's assume that the investment has been held for n quarters.
Then, we can use the following formula to calculate the expected rate of return:
Expected rate of return = (Ending value / Initial investment) ^ (1/n) - 1
Plugging in the given values, we get:
n = 1 (since we are only given information for a single quarter)
Initial investment = 26,245
Ending value = 26,292
Expected rate of return = (26,292 / 26,245) ^ (1/1) - 1 = 0.18%
Comparing the expected rate of return of 0.18% with the reported rate of return of -0.02%, we can see that they are quite different. However, it's important to note that a single quarter's rate of return may not be indicative of the overall performance of the investment.
Therefore, while the reported rate of return seems lower than expected, we would need to consider the performance over a longer period of time to make a more informed assessment of the investment's performance.

A statement which could be true for g is that: D. g(-13) = 20.
What is a domain?In Mathematics and Geometry, a domain can be defined as the set of all real numbers for which a particular function is completely defined.
How to determine the true statement?Since the domain of this function is given by -20 ≤ x ≤ 5, it simply means that the value of x must between -20 and 5. Also, with a range of -5 ≤ g(x) ≤ 45, the value of x must between -5 and 45.
By extrapolating the function, we can deduce that:
g(0) = -2
g(-9) = 6
g(-13) = 20
In this context, we can reasonably infer and logically deduce that based on the answer options provided, g(-13) = 20 is the only statement that could be true for the function g.

Find the surface area of a pyramid (which has 4 triangular sides and 1 square base) that has triangular height of 6 feet and base length of 4 feet.
The surface area of the pyramid is 64 square feet.
What is triangle?
A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.
To find the surface area of the pyramid, we need to find the area of each face and add them together.
First, let's find the area of the base, which is a square with side length 4 feet:
Area of base = 4 feet x 4 feet = 16 square feet
Next, we need to find the area of each triangular face. We know that the height of each triangular face is 6 feet, and the base of each triangular face is one of the sides of the square base, which is 4 feet. To find the area of a triangle, we use the formula:
Area of triangle = 1/2 x base x height
Area of each triangular face = 1/2 x 4 feet x 6 feet = 12 square feet
There are 4 triangular faces, so the total area of all the triangular faces is:
Total area of triangular faces = 4 x 12 square feet = 48 square feet
Now we can find the total surface area by adding the area of the base and the area of the triangular faces:
Total surface area = area of base + area of triangular faces
Total surface area = 16 square feet + 48 square feet
Total surface area = 64 square feet
Therefore, the surface area of the pyramid is 64 square feet.

according to the question the balance in the account earning compound interest after 6 years is $4,156.22.
what is interest ?Multiply the principal with the rate of interest, the time period, and various other factors to determine simple interest. Simple returns = money + interests + hours is the marketing formula. This approach makes calculating interest the simplest. The approach to calculating interest that is most usually employed is as a percentage over the principal sum. For instance, he will just pay his share of the interest at 100% when he borrows $100 with a friend and agrees to shell out it back with 5% interest. $100 has been reduced to $5 (0.05). Every time you borrow money, you must pay interest, which is applied to whatever loans you make. On the loan balance, interest is typically calculated using an annual percentage.
given,
To calculate the balance in the account earning compound interest after 6 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the sum of money at the end of the period of time
P stands for the principle (beginning sum).
the decimal representation of the annual interest rate (r).
n represents how many times the interest rate is compounded annually.
t is the duration (in years).
In this case, we have:
P = $3500 (the principal)
r = 2.16% = 0.0216 (the annual interest rate)
Since interest is compounded four times a year (quarterly), n is equal to four.
t = 6 (the time period is 6 years)
With these values entered into the equation, we obtain:
A = 3500(1 + 0.0216/4)^(4*6)
A = $4,156.22
Therefore, the balance in the account earning compound interest after 6 years is $4,156.22.

The balance in the account earning compound interest after 6 years when the principal is $3500 at an annual interest rate of 2.16% compounded quarterly is approximately $4,029.53.
What is compound interest?Compound interest is the term used to describe the interest that is calculated on both the initial investment and any accumulated interest. It is interest on top of interest, to put it another way.
We can use the formula for compound interest to find the balance in the account after 6 years:
A = P(1 + r/n)^(nt)
where:
A = balance after 6 years
P = principal = $3500
r = annual interest rate = 2.16%
n = number of compounded times per year = 4 (quarterly)
t = time in years = 6
Plugging in the values, we get:
A = 3500(1 + 0.0216/4)^(4×6)
A ≈ $4,029.53

how does cot^2(x)-tan^2(x)=csc^2(x)-sec^2(x)
The proof of cot²(x) - tan²(x) = csc²(x) - sec²(x) is the help of trigonometry
identity and Pythagorean identity .
what is trigonometry identity ?A trigonometric identity is an equation that is true for all values of the variables in the equation, where the variables are trigonometric functions such as sine, cosine, tangent, cotangent, secant, or cosecant.
The Pythagorean identity is a fundamental trigonometric identity that relates the three basic trigonometric functions: sine, cosine, and tangent, in terms of the unit circle or right triangle.
Proof of cot²(x) - tan²(x) = csc²(x) - sec²(x)The identity you provided, cot²(x) - tan²(x) = csc²(x) - sec²(x), is a trigonometric identity that can be derived from the Pythagorean identity and the reciprocal identities. Here's one way to prove it:
Start with the Pythagorean identity:
sin²(x) + cos²(x) = 1
Divide both sides by sin²(x):
1 + cos²(x)/sin²(x) = 1/sin²(x)
Recall that cot(x) = cos(x)/sin(x) and tan(x) = sin(x)/cos(x):
1 + cot²(x) = csc²(x)
Subtracting sec²(x) from both sides:
cot²(x) - tan²(x) = csc²(x) - sec²(x)
Therefore, cot²(x) - tan²(x) = csc²(x) - sec²(x) is a valid trigonometric identity.

Downtown Mathville is laid out as a 6 x 6 square grid of streets (see diagram below). Your apartment is located at the southwest corner of downtown Mathville (see point H). Your math classroom is located at the northwest corner of downtown Mathville (see point M). You know that it is a 12-block walk to math class and that there is no shorter path. Your curious roommate (we’ll call her Curious Georgia) asks how many different paths (of length 12 blocks – you don’t want to back track or go out of your way) could you take to get from your apartment to the math class. It should also be clear that no shorter path exists. Can you solve Curious Georgia’s math problem?
Yes, we can solve Curious Georgia's math problem using the concept of combinations.
There are 924 different paths we can take from our apartment to the math classroom, each of which is exactly 12 blocks long and does not backtrack or go out of the way.

Yes, we can solve Curious Georgia's math problem using the concept of combinations.
Since we cannot backtrack or go out of our way, we need to take exactly 6 blocks to the north and 6 blocks to the east to reach the math classroom.
This means that we need to choose 6 out of the 12 blocks to go north, and the remaining 6 blocks will be used to go east.
The total number of paths we can take is the number of ways we can choose 6 blocks out of the 12 blocks.
This can be calculated using the combination formula:
[tex]^nC_r[/tex] = n! / r!(n-r)!
where n is the total number of objects, r is the number of objects to choose, and ! represents the factorial function
In this case,
we have n = 12 and r = 6.
The number of paths.
= [tex]^{12}C_6[/tex]
= 12! / 6!(12-6)!
= 924
Therefore,
There are 924 different paths we can take from our apartment to the math classroom, each of which is exactly 12 blocks long and does not backtrack or go out of the way.
