What is sales tax ?A sales tax is a consumption tax imposed by the government on the sale of goods and services
The cocktail table sold for $250 and the sales tax amount was $13.75. The sales tax rate can be calculated as follows:
Sales tax = list price * sales tax rate
Therefore,
sale tax rate = sales tax / list price
sales tax = $13.75
list price = $250
sale tax rate = 13.75 / 250

How many cubic inches are in an aluminum can with a 2 3/5 diameter and 5 1/4 in height?
According to the volume of cylinder formula, an aluminum can with a 2 3/5 diameter and 5 1/4 in height are in 27.86 cubic inches.
Volume of Cylinder
The formula to calculate the volume of the cylinder is
Volume of a cylinder = πr²h cubic units.
where
r refers the radius
h refers the height.
Given,
Here we have an aluminum can with a 2 3/5 diameter and 5 1/4 in height and now we have to find the volume in cubic inches.
While we looking into the given question, we know the following values,
Diameter = 2 3/5
When we simplify it, then we get the value of diameter as
d = 13/5 or 2.6
Similarly, the value of height is rewritten as,
h = 5.25
So, based on the formula of volume of cylinder,
We get the value as,
=> V = π x (2.6/2)² x 5.25
Apply the value of π as 3.14, then we get,
=> V = 3.14 x (1.3)² x 5.25
=> V = 16.485 x 1.69
Therefore, the volume in cubic inches is 27.86 cubic inches.

√24x⁵y³
= √(2)(2)(2)(3)(x)(x)(x)(x)(x)(y)(y)(y)
= √(2²)(2)(3)(x²)(x²)(x)(y²)(y)
= √(2²) * √(2) * √(3) * √(x²) * √(x²) * √(x) * √(y²) * √(y) ...(seperate the radical symbol)
= 2 * √(2) * √(3) * x * x * √(x) * y * √(y) ...........exponent rule
= 2x²y√(2)(3)(x)(y) ........(combine terms with same powers)

Which pair of lines are perpendicular?
A. y = -8 and y = 2
B. x = 4 and y = -1
C. x-y = 7 and y = x + 3
D. y = -4x + 1 and 8x + 2y = -10
Applying the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.
There are 4 different pairs of lines given to us.
We have to find out the pair of lines that are perpendicular to each other.
We know that the general equation of a line in slope-intercept form is represented as -
y = mx + c --- (1)
where
(x, y) = coordinates of the lines
m = slope of the line
c = y-intercept
It is also known to us that for two lines to be perpendicular the product of their slope must be equal to -1.
A. y = -8 and y = 2
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
B. x = 4 and y = -1
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
C. x - y = 7 and y = x + 3
Now, x - y = 7
=> -y = 7 - x
=> y = x - 7
Comparing this to the equation (1), we have slope of the line, m = 1.
Also, y = x + 3
Comparing this to the equation (1), we have slope of the line, m = 1.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
D. y = -4x + 1 and 8x + 2y = -10
Now, y = -4x +1
Comparing this to the equation (1), we have slope of the line, m = -4.
Also, 8x + 2y = -10
=> 2y = -8x - 10
=> y = -4x - 10
Comparing this to the equation (1), we have slope of the line, m = -4.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
Thus, according to the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.

Step-by-step explanation:
There are several types of congruence:
ASA - Angle Side Angle
AAS - Angle Angle Side
HL - Hypotenuse Leg
This image shows two triangles which have 2 congruent sides and one congruent angle.
Is it ASA?
There is only one congruent angle, so this cannot be congruent by ASA
Is it AAS?
By the same reasoning, it cannot be congruent by AAS.
Is it HL?
Although there are 2 congruent sides, neither one is the hypotenuse. Is is not congruent by HL.
There is no such thing as SSA congruence, because it is actually possible to have 2 non-congruent triangles who have 2 congruent sides and 1 congruent angle. Therefore, these are NOT CONGRUENT

find the slope of (-4,4) (0,0)
The slope for the following question is = 4.
What is slope?Slope is used to describe the steepness of a line. The definition of slope is the rise of a line over the run of a line, or the change in the vertical direction (y) over the change in the horizontal direction (x). When one thinks of skiing down a hill or climbing up a mountain, the angle at which they are descending or ascending is the slope. Sometimes the slope can be fairly flat or very steep depending on what it is.The slope of an object indicates how steep it is. Slope knowledge is crucial for daily decision-making. For instance, understanding a roof's slope enables builders to determine whether specific construction materials are required for shingling projects. Since there must be sufficient grade for water to pass through the tile, slope is crucial in agriculture when tiling a field. Slope can also be calculated using elevation points on a GIS, a type of digital map that can highlight areas with sharp elevation changes in the ground.acc to our question-

What is Simple Interest?
Simple interest is a quick and simple way to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of many forms of interest that banks charge. Now, let's first clarify what a loan is before delving further into the idea of simple interest. A loan is a sum of money that someone borrows from a bank or other financial institution to cover expenses. Home loans, auto loans, student loans, and personal loans are a few instances of loans.
In the given question we have:
Principal amount = 7000$,
Rate of interest r = 7.5%,
Time t = 15 months;
So, applying the formula to calculate simple Interest:

m is the slope
c is the y intercept
From the question
m = - 43
In order to find c we substitute the point (0,−25) into the equation y = mx + c
