Answer:
3.19
Step-by-step explanation:
5.5% of 58 is 3.19
and is you need it,
58 - 3.19 = 54.81
I believe this is right
the sales tax on $58 at a rate of 5.5% is $3.19
How to find the tax on $58 at a rate of 5.5%?
Taxes are a mandatory contribution to the state. So sales must pay taxes, and it is stated that the rate of tax that must be paid is 5.5%
The way to calculate tax from sales is to multiply the tax rate by the income from sales.
the income = $58
the rate of tax = 5.5%
the tax to be paid by sales = the income x the tax
= $58 x 5.5%
= $3.19
so the answer to the question is $3.19

for the stem and leaf plot created in question 9 are there any extreme values? if so, what are they?
As a result, the extreme stem values may contain fewer rows than the other stem values. In our graph, the extreme stem values are 1 and 4, and they both have fewer rows than the middle values (2 and 3).
The shape and spread of a continuous data distribution are depicted by stem and leaf plots. These graphs are similar to histograms, but instead of bars, they display numbers.
Statistical software packages use an algorithm to improve our ability to read stem and leaf plots by displaying multiple rows of each stem value based on the properties of the data, as shown in the body fat percentage graph. There are two ones, five twos, five threes, and four fours.
The graph divides stem values into five rows for the body fat percentage data. Each row only has two leaf values (e.g., 0 and 1, 2 and 3, etc.) The leaf values terminate at the dataset's minimum and maximum values.

What are quadratic Equation ?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
When a quadratic equation is solved, the two values of x that result are known as the roots of the equation. The zeros in the equation are another name for these quadratic equation roots. For instance, x = -1 and x = 4 are the roots of the equation x² - 3x - 4 = 0 since they each fulfill it.
The easiest method for locating a quadratic equation's roots is the quadratic formula. There are some quadratic equations that are difficult to factor, and in these cases we can quickly discover the roots by using the quadratic formula. The quadratic equation's roots also aid in determining the quadratic equation's sum of roots and product of roots. The quadratic formula's two roots are shown as a single statement.
The equation are :
x² - 9 = 0 ⇒ (x-3)(x+3) = 0 ,
sum of roots is 0
product of roots is -9
Discriminant = 0² - 4*3(-3) = 36
The second equation :
4x² + 25 = - 20x ⇒ 4x² + 20x + 25 = 0 ⇒ 4x² + 10x + 10x + 25 ⇒2x(2x + 5) +5(2x+5) = 0 ⇒ (2x +5)²

Find the slope of the graph: 4x - 16y = 20.
Please explain the steps!
Answer: y = 1/4x + -5/4
Step-by-step explanation:
Step 1: add -4x to both sides
step 2: Divide both sides by -16.
Answer:
Slope is [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Rearranging the equation:
[tex]4x - 20 = 16y[/tex]
The coefficient of y needs to be '+1' for the above equation to be considered as the slope-intercept form:
Dividing both sides of the equation by '16':
[tex]\frac{16}{16}y = \frac{1}{16}(4x -20)[/tex]
[tex]y = \frac{4}{16}x - \frac{20}{16}[/tex]
Divide the numerator and denominator present in the coefficient of x by the Highest Common Factor '4'. Also divide the numerator and denominator present in the coefficient of 'non-x' term by the Highest Common Factor '4':
[tex]y = \frac{1}{4}x - \frac{5}{4}[/tex]
The simplified form of the slope-intercept of the equation has been achieved. The coefficient of x is the slope of the graph:

Let d be the distance the dog needs to walk to get to the donut. We can use trigonometry to solve for d.
Since the angle of depression from Ted's line of sight to the dog is 40 degrees, the angle between the ground and Ted's line of sight is 90 - 40 = 50 degrees.
We can use the tangent function to find d:
tan(50) = opposite / adjacent
The opposite side is the height of Ted's eye level above the ground, which is 16 feet. The adjacent side is d, the distance the dog needs to walk to get to the donut.
tan(50) = 16 / d
d = 16 / tan(50)
d ≈ 12.6 feet

PM= 15in.
What is LN
In this question, the length of the chord LN will be 15 inches long. It will be equal to PM.
Given,
At the circle's Centre, the Arc PL subtends an angle of 10 degrees.
At the circle's Centre, the Arc LM subtends an angle of 14 degrees.
At the circle's Centre, the Arc LN subtends a 24 degree angle.
The PM chord measures 15 inches in length.
What are the circle's chord theorems?
Considering the attached figure now,
The angle that the Arc PM creates at the Centre is equal to the sum of the angles that the Arc PL and Arc LM make there.
So,
At the middle, Arc PM will create the following angle: 10+14=24 degree.
We are aware that if the chords that make up the arc are equal, then the angle that it subtends in the Centre of the circle will likewise be equal.

Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
Cosine of ∠U is 28/53 in proper fraction, 28/53 in improper fraction, 0.52609 in whole number.
The cosine of an angle in a right triangle can be found using the ratio of the adjacent side to the hypotenuse. In this triangle, the adjacent side to ∠U is 28 and the hypotenuse is 53.
cos(∠U) = adjacent side ÷ hypotenuse = 28 ÷ 53 = 28/53
So, the cosine of ∠U is 28/53, written as a proper fraction.
Now let's convert cosine of ∠U is 28/53 in improper fraction:
The cosine of ∠U, which is 28/53, can be expressed as an improper fraction by dividing both the numerator and denominator by their greatest common factor.
gcd(28, 53) = 1, so the fraction cannot be further simplified.
Therefore, the cosine of ∠U, expressed as an improper fraction, is 28/53.
Now let's convert cosine of ∠U is 28/53 in whole number:
The cosine of ∠U, which is 28/53, can be expressed as a whole number by dividing the numerator by the denominator.
28 ÷ 53 = 0.526087
So, the cosine of ∠U expressed as a whole number is approximately 0.52609

What is compound interest?The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
Given the interest rate = 12.5% = 0.125
principal = $12,000
time period = 6 months
CI is given by,
CI = [tex]p(1 + \frac{r}{n})^{nt}[/tex]
n = 1
substitute the values,
A = 12000(1 + (0.125/1))¹ˣ⁶
