Carol’s last credit card statement said that she had an account balance of -$130. Which of the following accounts balances represents a debt greater than Carol’s?
A debt greater than Carol's would bear a value that is numerically larger but still under the negative sign. In simpler terms, any debt greater than -$130 is indeed a greater debt.
Explanation:The question asks, 'Which of the following account balances represents a debt greater than Carol's?' When working with debts in math, it's important to remember that the larger the number, the greater the debt. So any number larger than -$130 represents a debt greater than Carol's.
For example, a balance of -$150 would be a larger debt than Carol's -$130. Why? Because when you owe $150, it's more than owing $130, despite the negative sign. Conversely, a balance of -$100 would be less of a debt than Carol's, because owing $100 is less than owing $130.
It's a somewhat counterintuitive part of working with negative numbers, but once you understand that the negative sign represents a debt, it starts to make sense. The concept of debt here is similar to examples provided where people often have a tendency to hold onto a savings account while carrying a credit card debt.

Chen completed the division problem below.
Answer:
B. He multiplied the dividend by 100 instead of 10.
Step-by-step explanation:
Chen had to divide [tex]1.926[/tex] by [tex]0.9[/tex]. To make it easier to divide, he thought of multiplying both the dividend and the divisor by 10.
Chen multiplied the divisor by 10 but mistakenly multiplied the dividend by 100 instead of 10.
So his whole division problem was changed.
Therefore, the correct answer option is B. He multiplied the dividend by 100 instead of 10.
Answer:
option B
He multiply the dividend by 100 instead of 10
Step-by-step explanation:
Given that,
divisor = 0.9
dividend = 1.926
Chen decided to multiply each by 10 to get
divisor = 0.9 x 10 = 9
dividend = 1.926 x 10 = 19.26
but unfortunately he multiply the dividend by 100
As,
1.926 x 100 = 192.6
So,
Chen's error was that he multiply the dividend by 100 instead of 10.

which value of b makes the trinomial a perfect square
Answer:
12
Step-by-step explanation:
Given trinomial is [tex]x^2-bx+36[/tex].
Now we need to find the value of b that will make the trinomial [tex]x^2-bx+36[/tex] a perfect square.
[tex]x^2-bx+36[/tex]
[tex]=x^2-bx+36[/tex]
[tex]=x^2-bx+6^2[/tex]
compar with [tex]=a^2-2ab+b^2=(a-b)^2[/tex]. we get:
a=x and b=6
then middle term -2ab=-2(x)(6)=-12x
compare -12x with -bx, we get b=12
Hence choice C. 12 is correct.
Answer:
The correct answer is option C. 12
Step-by-step explanation:
It is given a quadratic expression
x² - bx + 36
To find the value of b
From the above expression we can see that 36 is a perfect square,
6² = 36
We can write this expression as ( x - 6)² if b = 12
(x - 6)² = x² - 12x + 36
Therefore the correct answer is option C. b = 12

where:
r is the radius of the baseh is the heightπ is a mathematical constant approximately equal to 3.14Given that the height (h) is 9 inches and the base radius (r) is 4 inches, you can substitute these values into the formula:
SA = 2 × 3.14 × [tex](4)^2[/tex]+ 2 × 3.14 × 4 × 9
SA = 2 × 3.14 × 16 + 2 × 3.14 × 36
SA = 100.48 + 226.08
SA = 326.56
Therefore, the surface area of the cylinder is

A farmer has 1600 yards of fencing to enclose a rectangular garden. Express the area A of the rectangle as a function of the width x of the rectangle. What is the domain of A?
Answer:
A = (800 yd - x)x, [0, 800]
Step-by-step explanation:
The farmer fences in this rectangular garden using 1600 yds of fencing. Using the formula for the perimeter of a rectangle,
P = 2x + 2L, where x is the width and L is the length. Here P = 1600 yd.
Solving for L: 1600 yd = 2x + 2(L) → 800 yd = x + L → L = 800 yd - x.
The area of the rectangle is A = L·x. Subbing (800 yd - x) for L, we get:
A = (800 yd - x)x. This is the desired formula for the area of the rectangle as a function of x alone. Neither length nor width can be negative, so the domain of this function A is x ≤ 800 yd.
Let the length of the rectangular garden = l yards
And the width of the garden = w yards
Farmer has the fence in length = 1600 yards to cover all the sides of the garden
Therefore, Perimeter of the rectangular garden = 1600 yards
Since, perimeter of the rectangular garden is given by the expression,
Perimeter = 2(l + w)
By substituting the values in the expression,
1600 = 2(l + x)
l + x = 800
l = 800 - x -------(1)
Since, area of the rectangle = Length × Width
= l × w
= lx
Therefore, by substituting the value of 'l' in terms of 'x' in from equation (1),
Area of the rectangular garden = (800 - x)x
If the area of the garden is represented by by the function A(x),
A(x) = (800 - x)x
A(x) = 800x - x²
Since, Area can not be negative or zero,
Domain of the function will be 0 < x < 800

The reduced row-echelon form of the augmented matirx of a system of equations is given. Find the solution of the system.
Answer:
option C)
(19,2,5)
Step-by-step explanation:
| 4 | x
| 12 | y
| 5 | z
After reducing the matrix in row-echelon form we are left with three equation as following
Equation 1
0x + 0y + 1z = 5
Equation 2
0x + y1 + 2z = 12
Equation 3
1x + 0y -3z = 4
SolutionAs in first equation
0 + 0 + z = 5
z = 5
Put this value of z in equation 2 and 3
y + 2(5) = 12
y + 10 =12
y = 12 - 10
y = 2
x + 0 -3(5) = 4
x - 15 = 4
x = 4 + 15
x = 19
So the solution of the system is (x,y,z) = (19,2,5)

How do you think a graph of the scientist’s data will differ from the graph representing the population growth in the game, if at all?
Final answer:
A real-world population growth graph may differ from a game's graph in terms of actual population numbers, reflecting real-life constraints versus game assumptions, although the overall S-shape indicating logistic growth may be similar. This shows the importance of graph type and display in interpreting growth rates and relationships in data.
Explanation:
When comparing a graph of a scientist’s data on population growth to a graph representing population growth in a game, there may be notable differences. The x-y values on the graphs indicating the time frames for the growth curves would generally be the same since time is a consistent measure. However, while the overall S-shape of a logistic growth model might be similar, representing the slowdown in growth as the population reaches carrying capacity, the actual population numbers corresponding to the starting populations could differ based on real-world limitations versus game conditions.
Further, displaying data graphically helps in interpreting growth rates and relationships between data points. For instance, in a scenario where an individual receives a $2 raise each year, the growth rate decreases over time unless the raise amount also increases. In terms of graphing, economists and other professionals use various types of graphs like pie charts or bar graphs to visualize data, such as the distribution of hours played amongst students, or the comparison of populations among countries. The choice of the graph type and how it's displayed can impact the interpretation of the data.
Moreover, when comparing real data with that from a game, the assumptions and simplifications made in a game's model might not perfectly reflect real-life complexities, leading to different population growth dynamics and consequently different shapes of the graph beyond just the starting population numbers.

To solve the system of equations y - 2x = 1 and 6x - y = 7, we use the elimination method. By aligning the equations and setting the right sides equal, we can solve for 'x' and then 'y', resulting in the solution x = 2 and y = 5.
Solving the System of Equations
To solve the system of equations:
y - 2x = 1
6x - y = 7
We can use the method of substitution or elimination. In this case, the elimination method seems efficient. Let's align the equations:
y = 2x + 1
6x - y = 7
We can eliminate y by adding the two equations. First, rearrange the second equation:
y = 2x + 1
y = 6x - 7
By setting the right sides equal to each other, we get 2x + 1 = 6x - 7. Solving for x gives us x = 2 and substituting x back into either equation yields y = 5.
Therefore, the solution to the system of equations is x = 2 and y = 5.
