The surface area of the cube with a side length of 5.5 yards is 181.5 square yards.
To find the surface area of a cube with a side of 5.5 yards, we need to add up the areas of all six sides of the cube.
The formula for the surface area of a cube is
SA = 6s²
where SA is the surface area and s is the length of the side.
Substituting s = 5.5 yards into the formula, we get
SA = 6(5.5)²
SA = 6(30.25)
SA = 181.5 square yards
Therefore, the surface area of the cube is 181.5 square yards.

multiplying radical expressions √6(√2+ √6)
Multiplying radical expressions √6(√2 + √6) involves multiplying the coefficients and then multiplying the radicands. Therefore, the final answer is 2√12 + 6√6.
What does multiplying radical mean?The multiplication of two radicals can be done by using the product rule which states that the product of two radicals is equal to the product of the coefficients and the product of the radicands.
Multiplying radical expressions involves multiplying the coefficients and then multiplying the radicands.
In this case, the coefficients are 1 and the radicands are √6 and (√2 + √6). The first step is to multiply the coefficients, which is 1*1 = 1.
The second step is to multiply the radicands, which is √6*(√2 + √6).
In this case, the product of the radicands is (√2 * √6) + (√6 * √6).
This can be simplified to 2√12 + 6√6.
Therefore, the final answer is 1*(2√12 + 6√6) = 2√12 + 6√6.

your salary is 29000 and you receive 125 interest from an investment account. what is your after tax return on the investment
Step-by-step explanation:
To calculate your after-tax return on investment, we need to know your tax rate. Let's assume your tax rate is 20%.
Your total income from the salary and interest is:
$29,000 + $125 = $29,125
Your tax liability on this income is:
$29,125 * 20% = $5,825
So your after-tax income is:
$29,125 - $5,825 = $23,300
Your after-tax return on the investment is:
$125 / $23,300 = 0.0054 or 0.54%
Therefore, your after-tax return on the investment is 0.54%.

The formula for the curved surface area of a cylinder is given by:
Curved Surface Area = 2 × pi × radius × height
where pi is the mathematical constant approximately equal to 3.14, radius is the distance from the center of the circular base to the edge of the cylinder, and height is the distance between the two circular bases of the cylinder.
Given, the radius of the cylinder is 7 cm and the height is 2 cm, we can substitute these values in the above formula to find the curved surface area:
Curved Surface Area = 2 × (22/7) × 7 cm × 2 cm
= 2 × 22 × 2 cm^2
= 88 cm^2
Therefore, the curved surface area of the cylinder is 88 square centimeters.

Find the number that is 1.5 standard deviations BELOW the mean. (Round your answer to three decimal places.)
The number that is 1.5 standard deviations below the mean is approximately 0.631.
What is a standard deviation?Standard deviation is a measure of the amount of dispersion in a set of data. It measures how much the data values deviate from the mean of the data set. A smaller standard deviation indicates that the values tend to be close to the mean, while a larger standard deviation indicates that the values are more spread out from the mean. Standard deviation is commonly used in statistical analysis to measure the spread of a data set and to help identify outliers.
To find the number that is 1.5 standard deviations below the mean, we first need to calculate the mean and standard deviation of X.
The mean is:
μ = Σ(x * f) / n = (0*3 + 1*15 + 2*30 + 3*27 + 4*11 + 5*7 + 6*7) / 100 = 2.77
The variance is:
σ^2 = Σ[(x - μ)^2 * f] / (n-1)
= [(0-2.77)^2*3 + (1-2.77)^2*15 + (2-2.77)^2*30 + (3-2.77)^2*27 + (4-2.77)^2*11 + (5-2.77)^2*7 + (6-2.77)^2*7] / (100-1)
= 2.0346
The standard deviation is:
σ = [tex]\sqrt{2.0346}[/tex] = 1.426
Now we can find the number that is 1.5 standard deviations below the mean:
2.77 - 1.5(1.426) = 0.631
Therefore, the number that is 1.5 standard deviations below the mean is approximately 0.631.

Larry needs to hire a new employee. Current projections indicate that the department will generate 8 million USD in gross revenue. Larry is expected to maintain a 15% annual profit margin. Current projected expenses for the year are 6.3 million USD. For budgeting purposes, the actual cost of an employee is assumed to be twice the employee’s annual salary. Based on his budget and current projections, what is the maximum salary Larry can offer a new employee?
The maximum salary Larry can offer a new employee per annum is $250,000.
How the maximum salary is determined:The maximum salary conferrable on a new employee is based on projections, worked out as follows:
The gross revenue to be generated = $8 million
Annual profit margin = 15% or $1.2 million ($8 million x 15%)
Current projected expenses for the year = $6.3 million
Actual cost of an employee = $0.5 million ($8 - 1.2 - 6.3)
Maximum salary = $250,000 ($0.5 million x 50%).
Thus, based on current projections of a gross revenue of 8 million USD with a 15% annual profit margin and projected expenses of 6.3 million, the maximum salary that Larry can offer a new employee is $250,000.

Louis rolled a fair six-sided die and recorded the number that was facing up on the die. He continued this for a total of 80 rolls. The table shows the frequency of each number rolled.
Outcome 1 2 3 4 5 6
Frequency 15 11 14 15 10 15
Based on the table, what is the experimental probability that the number rolled was odd?
41 over 80
39 over 80
5 over 12
1 over 2
39 over 80 will be the probability of getting desired outcomes.
Finding the total number of rolls that produced an odd number and dividing that by the total number of rolls will yield the experimental probability that the number rolled was odd.
80 rolls are listed as the total. We sum the frequency of the odd numbers to determine the total number of rolls that produced an odd number:
Total frequency of odd numbers = frequency of 1 + frequency of 3 + frequency of 5
= 15 + 14 + 10
= 39
the following is the experimental likelihood that the number rolled was odd:
The frequency of odd numbers divided by the total number of rolls gives the probability of rolling an odd number.

So the domain of m(x) is: Domain: x ∈ (-∞,-8) ∪ (-8,-3) ∪ (-3,5) ∪ (5,∞). So, as x approaches -3, m(x) approaches 4/3. So, the x-intercepts of m(x) are x=5 and x=-8. So, the y-intercept of m(x) is y=-32/3.
What is function?A function is a mathematical relationship between two sets of numbers, where each element in the first set (called the domain) is paired with a unique element in the second set (called the range). In other words, it is a rule or mapping that assigns each input value in the domain to exactly one output value in the range. Functions are often written in the form f(x) = y, where f is the name of the function, x is the input value, and y is the output value.
Here,
1. The denominator of the rational function cannot be equal to zero. Thus, x cannot be equal to -3 and x cannot be equal to 5 or -8, as those are the roots of the denominator. So the domain of m(x) is:
Domain: x ∈ (-∞,-8) ∪ (-8,-3) ∪ (-3,5) ∪ (5,∞)
2. To find the limit of m(x) as x approaches -3, we can simply substitute -3 for x in the function:
m(x) = (4(x-5)(x+8))/(x²-2x-15)
m(-3) = (4(-3-5)(-3+8))/((-3)²-2(-3)-15)
m(-3) = 32/24
m(-3) = 4/3
3. To describe the end behavior of m(x), we can look at the degree of the numerator and denominator. The degree of the numerator is 2 and the degree of the denominator is also 2. Thus, the end behavior of m(x) is:
As x approaches positive or negative infinity, m(x) approaches the horizontal asymptote y=4/1 or y=4.
4. To find the x-intercept, we set m(x) equal to zero and solve for x:
(4(x-5)(x+8))/(x²-2x-15) = 0
4(x-5)(x+8) = 0
x = 5 or x = -8
So, the x-intercepts of m(x) are x=5 and x=-8.
To find the y-intercept, we set x equal to zero and simplify:
m(0) = (4(0-5)(0+8))/(0-2(0)-15)
m(0) = -160/15
m(0) = -32/3
So, the y-intercept of m(x) is y=-32/3.

The solution by completing the square for the equation x² + 3x = 24 is x ≈ 3.55 or x ≈ -6.55, which is (3.55, -6.55) when rounded to the nearest hundredth. The correct answer is A).
To solve by completing the square, we need to take half of the coefficient of x, square it, and add and subtract it to both sides of the equation. Then, we can factor the left side and solve for x.
Starting with the equation
x² + 3x = 24
First, we add and subtract (3/2)² = 2.25 to both sides
x² + 3x + 2.25 - 2.25 = 24
(x + 1.5)² = 26.25
Taking the square root of both sides
x + 1.5 = ±√26.25
x = -1.5 ± √26.25
Rounding to the nearest hundredth, we get
x ≈ 3.55 or x ≈ -6.55
So the answer is (3.55, -6.55). The correct option is A).

An equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers is 10t = b - 4.
An equation with t and b that describes this situation is 8t + 12b = 348.
An equation that shows this substitution is 8t + 12(10t + 4) = 348.
The value of b is equal to $27.4.
The amount of money which the school paid for a set of beakers is $27.4 and $2.34 for a pack of test tubes.
How to write an equation to model this situation?In order to write a linear equation to describe this situation, we would assign variables to the cost of a pack of test tubes and the cost of a set of beakers respectively, and then translate the word problem into a linear equation as follows:
Let the variable t represent the cost of a pack of test tubes.Let the variable b represent the cost of a set of beakers.Since a pack of 10 test tubes costs $4 less than a set of nested beakers, a linear equation which can be used to model the cost of a pack of test tubes with respect to the cost of a set of beakers is given by;
10t = b - 4 .....equation 1.
For t and b, a linear equation which can be used to model the total cost is given by;
8t + 12b = 348 .....equation 2.
By making b the subject of formula in equation 1, we have;
b = 10t + 4
By substituting the value of b, we have;
8t + 12(10t + 4) = 348
8t + 120t + 48 = 348

What is the standard form of the equation of a quadratic function with roots of 3 and −1 that passes through (1, −10)?
y = 2.5x2 − 5x + 7.5
y = 2.5x2 − 5x − 7.5
y = −2.5x2 − 5x + 7.5
y = −2.5x2 − 5x − 7.5
Step-by-step explanation:
y = a(x-3)(x+1) sub in the given point to calculate 'a'
-10 = a( 1-3)(1+1)
-10 = -4a
a = 2.5
then y = 2.5 ( x-3)(x+1) = 2.5 x^2 -5x -7.5
