Step-by-step explanation:
To find the most significant difference in Bella's budget, calculate the difference for each category and compare them. For Mary Ann, by subtracting her expenses from her net income of $2,589.10, we determine she can save more than 10% of her income, exceeding her savings goal.
Explanation:The most significant difference between Bella's actual spending and her budget can be determined by comparing the projected expenses to the actual expenses in each category. You'll first calculate the difference for each category by subtracting the actual amount from the projected amount. These differences should be compared to determine which one is the largest. For Mary Ann's scenario, we can construct a budget table and calculate the possibility of saving 10% of her after-tax monthly income by deducting her monthly expenses from her net income. To do this, you'll start with her net monthly income and subtract each of her monthly expenses to check if there's at least 10% of her income left for savings.
If Mary Ann's net monthly income is $2,589.10, her goal is to save 10% of that amount, which would be $258.91. Once you subtract her expenses which total $2,145 (the sum of rent, cell phone, utilities, cable TV and internet, groceries, entertainment, car payment, and gasoline) from her net income, you're left with $444.10. Therefore, she can meet her savings goal since $444.10 is more than $258.91. You can use similar steps and considerations for creating and managing a budget based on the cost of living in your area.
Equation 1: 5x + 3y = 19
Equation II: 2x - 4y = -8
In solving the system of equations, which operations will allow the elimination of the variable x in the next step?
Answer:
C
Step-by-step explanation:
If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!
To eliminate x, we need to make the coefficient of x the same in both equations. We achieve this by multiplying Equation I and Equation II by certain numbers. Subtraction of the modified equations then eliminates x, leaving one equation with y.
Explanation:To eliminate the variable x in the system of equations, we need to multiply each equation by a number that would make the coefficients of x in both equations equal, such that they cancel each other out when we add or subtract the equations.
For the given equations: Equation I: 5x + 3y = 19 and Equation II: 2x - 4y = -8, we can multiply Equation I by 2 and Equation II by 5.
This will result in:
Equation I: 10x + 6y = 38 and Equation II: 10x - 20y = -40
By subtracting Equation II from Equation I, we are able to eliminate the x variable, resulting in the equation 26y = 78.

A wave has a frequency of 900Hz and a wavelength of 200m at what speed is this wave traveling
Answer:
180000 m/s
Step-by-step explanation:
The frequency of the wave is 900 Hz.
The wavelength of the wave is 200 m.
The speed of a wave is given as the product of wavelength and frequency. That is:
v = λf
where λ = wavelength
f = frequency
The speed of the wave is therefore:
v = 200 * 900 = 180000 m/s
The speed of the wave is 180000 m/s.
what is q + 166 = 300?
what is 14.2 = t − 5.4?
Answer:
For the first one q is 134
And the second one is t is 8.8
Step-by-step explanation:
That is true cause 134 +166 = 300
and, 14.2 = 8.8 - 5.4.
Please Mark brainliest!
For the equations given, the value of q is found to be 134 after subtracting 166 from both sides, and the value of t is calculated as 19.6 by adding 5.4 to both sides.
To solve the first equation, q + 166 = 300, we need to isolate the variable q by subtracting 166 from both sides of the equation:
q + 166 - 166 = 300 - 166
q = 134
So, the value of q is 134.
For the second equation, 14.2 = t - 5.4, we need to isolate the variable t by adding 5.4 to both sides of the equation:
14.2 + 5.4 = t - 5.4 + 5.4
t = 19.6
Thus, the value of t is 19.6.

Answer:
x = 3.873 units
or x = [tex]\sqrt{15}[/tex] units
Step-by-step explanation:
Hypotenuse = 4 , x = height of this isosceles triangle.
base is 2,
so Use Pythagorean Theorem.
x^2 + 1^2 = 4^2
x^2 = 4^2 - 1^2
x^2 = 16 - 1 = 15
x = root(15) =
x-y = 2
6x + 4y = 92
First, let's rearrange the first equation so we can know what y equals to.
So, (x - y = 2) becomes (y = x - 2).
Now, we can plug this into the second equation so we can find x.
6x + 4(x - 2) = 92
6x + 4x - 8 = 92
10x - 8 = 92
10x = 100
x = 10
Now that we know x equals 50, we can plug this into either equations to find y. Let's use the first equation.
10 - y = 2
-y = -8
y = 8
Now, let's check our work by plugging int eh values of x and y for both equations.
First equation:
10 - 8 = 2
Second equation:
6(10) + 4(8) = 92
60 + 32 = 92
So, the values of x and y are correct.

Add or subtract.
7z2 − 2z4 − 2z2 − 5z4
To solve the given polynomial addition and subtraction question, combine like terms. The z4 terms combined are -7z4 and the z2 terms are 5z2, resulting in the simplified expression 5z2 - 7z4.
Explanation:To add or subtract the polynomials 7z2 − 2z4 − 2z2 − 5z4, you'll want to combine like terms. Like terms are terms that have the same variables raised to the same power.
Here, z2 and z4 are like terms, so you can combine them separately.
Starting with the z4 terms:
-2z4 and -5z4 combine to give you -7z4. They both have the same variable z raised to the fourth power, so you just add the coefficients, keeping the exponent the same.
Then, combine the z2 terms:
7z2 and -2z2 combine to give you 5z2.
Similarly, these terms have the same variable z raised to the second power.
Now, putting it all together, you get:
5z2 − 7z4
This is the simplified version of the polynomial after combining like terms.

The box plot was created by using which pieces of data? A) an upper quartile of 56 and a median of 50 B) a lower quartile of 56 and a median of 50 C) a median of 56 and a lower quartile of 50 D) a median of 56 and an upper quartile of 50
Answer:
A) an upper quartile of 56 and a median of 50
Step-by-step explanation:
Hello!
The lower and upper ends "box" from the box and whiskers plot is determined by the first (Q₁) and third (Q₃) quartiles of the data set and the line inside the box marks the median or second quartile of the sample (Q₂)
The length of the whiskers of the diagram is determined by the minimum value (left whisker) and the maximum value (right whisker)
If you observe the graphic:
Q₁= 42
Q₂= 50 (Median)
Q₃= 56
Min= 38
Max= 66
The box is delimited by a lower quartile of 42 and an upper quartile of 56, with a median 50, the least observation is 38 and the highest observation is 66.
The correct choice is A.

bob got a raise, and his hourly wage increased from 12 to 15. what is the percent increase?
25%
12x0.25=3

Using percentages we know that the percentage increase is 1.25%.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.So, the percentage increase:
Formula: Original price + amount increases/original priceThe amount increased: 15 - 12 = $3Now, calculate as follows:
Original price + amount increases/original price12 + 3/1215/121.25%
Therefore, using percentages we know that the percentage increase is 1.25%.

10/sin(40°) = AC
(10) sin(40%) =
Image is missing, so i have attached it.
Answer:
AC = 10sin 40°
Step-by-step explanation:
From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.
Thus, since we want to find AC;
We know that in trigonometric ratios; opposite/hypotenuse = sin θ
In the diagram, θ = 40° and AB = 10
Thus,
AC/10 = sin 40°
Multiply both sides by 10 to get;
AC = 10sin 40°
