1. A stands for the Area of the base. let's find our area! (This is length x width)
So this is 4x4=16
2. Now, P stands for PERIMETER of the base, which means we add all of the sides together. That would be 4+4+4+4=16.
3. Finally, S stands for Slant Height. Which is eight inches.
Lets plug our numbers in!

3. the difference of two-thirds of a number x and
6 is at least -24. which inequality represents all
possible values for x?
The inequality which represents all the possible values for x is (2x/3) - 6 ≥ 24.
It is given in the question that the difference of two-thirds of a number x and 6 is at least -24.
We have to find the inequality which represents all the possible values for x.
In mathematics, Inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Hence, according to the data given in the question, we can write,
(2x/3) - 6 ≥ 24
Here, we can also find the possible values of x.
(2x/3) - 6 ≥ 24
2x/3 ≥ 24 + 6
2x/3 ≥ 30
x ≥ 30*3/2
x ≥ 45
Hence, every number greater than or equal to 45 will be a possible value of x.

Write the coordinates of point N.
If we reflect the point (-5,2) (five, -two) over the x-axis (line of symmetry) the reflected point is (-5,-2). If we reflect the point (-5,2) (five, - two) over the y-axis (line of symmetry) the reflected point is (5,2).
What are the x-axis, and y-axis?
The vertical axis is generally called the x-axis. The perpendicular axis is generally called the y- axis. The point where the x- and y- axis intersect is called the origin. The x-axis is generally the vertical axis, while the y- axis is the perpendicular axis. They're represented by two number lines that cross perpendicularly at the origin, located at( 0, 0). The x-axis is also called the abscissa and the y- axis is called the ordinate.
The point (-5,2) is plotted as red in the picture attached.
To reflect a point over the x(ax)-axis, the x(ax) value must be the same and the y value must be the opposite.

GEOMETRY [35 POINTS]
What is the value of X?
What is the measure of angle A?
What is the measure of angle B?
Answer:
Step-by-step explanation:
Comment
The key to this is to know what a remote angle is. A remote angle is one that has one leg in common with the exterior angle. Make this a little simpler.
The exterior angle is outside the triangle. In this case it is the 157 degree angle.
The two remote angles each contribute just one side to the exterior angle. <B contributes BC and <A
Theorem
The two remote angles = the exterior angle.
Equation
x + x - 21 = 157
Solution
x + x - 21 = 157 Combine the left side
2x - 21 = 157 Add 21 to both sides
2x - 21 + 21 = 157+21 Combine
2x = 178 Divide by 2
2x/2 = 178/2
x = 89
Answer
x = A = 88
89 - 21 = B =68
how do you calculate these numbers from least to greatest −2.0, 0.25, −1.02, 1.98.?
Answer: -2.0, -1.02, 0.25, 1.98
Step-by-step explanation:
Remember that negative numbers always go last. The bigger the negative number is, the smaller its quantity is. So -2.0 is less than -1.02. Then we have the positive numbers: 0.25, and 1.98. 0.25 is less than 1.98 because 1.98 has a whole number and 0.25 doesn't have a whole. Hope this helps :)

The price of crude oil in 3.24 ¢ /cup.
What is conversion factor?A conversion factor is a number that is used to multiply or divide one set of units into another.
When converting to an equal value, the suitable conversion factor must be used. To convert inches to feet, for example, the suitable converting value is 12 inches equal 1 foot.A conversion factor is a ratio (and any fraction) that depicts the connection between two distinct units.Some conversion factors are-
One gallon = 4 quarts;
4 cups = 1 quart
( ¢ =cents)
Now, as per the given question;
The crude oil was sold at $21.75 per barrel.
The volume of the barrel is 42 gallons.
Let 'P' be the total price of crude oil in ¢ /cup.
To determine the price in cents per cup, we must use the conversion factors:
Price P = ($21.75/1 barrel)×(100 ¢/$ 1.00)×(1 barrel/42 gallons)×1 gallon/ 4 quarts)×(1 quartz/ 4 cups).
Simplify the above equation;
Price per cup P = 3.24 ¢ /cup.
Therefore, the price of crude oil is 3.24 ¢ /cup.

The cost of having a package delivered has a base fee of $9.10. every pound over 5 lbs costs an additional $0.42 per pound. write an equation that expresses the cost c in terms of w, the total weight in pounds of a package weighing over 5 lbs.
The expression c = 9.10 + 0.42(w-5) ; w > 5 will represent the cost c in terms of w, the total weight in pounds of a package weighing over 5 lbs.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Total cost below 5 lbs = base fee
Total cost over 5 lbs = base fee + additional 0.42/pound
Let's say the total cost is c and the total pounds is w
Then,
c = 9.10 + 0.42(w-5) ; w > 5
Here for w = 6 it will gives w - 5 = 6 - 5 = 1 lbs.
Hence "The expression c = 9.10 + 0.42(w) ; w > 5 will represent the cost c in terms of w".

The equation of the function g(x) is g(x) = -2|x - 2| + 5
How to determine the equation of the function g(x)?The function f(x) is given as
f(x) = 2|x - 2| - 5
The rule of the transformation is a reflection across the x-axis
This is represented as
g(x) = -f(x)
So, we have
-f(x) = -2|x - 2| + 5
Substitute g(x) = -f(x) in -f(x) = -2|x - 2| + 5
g(x) = -2|x - 2| + 5

A is between c and t. if ct = 25 and at = 18, what is the length of segment ca?
The length of the segment CA is 7.
Length of the segment
Basically, length of the line segment is fixed, which is the distance between two fixed points.
The length here can be measured by metric units such as centimeters (cm), millimeters (mm) or by conventional units like feet or inches.
Given,
A is lies between C and T.
Then the values of CT = 25 and AT = 18.
Now we have to find the length of the segment CA.
Consider the point C, A and T are in straight line.
Then A lies between C and T.
So, it is the center point between C and T.
Here we have the length of total line that is
=> CT = 25.
And the length of AT, that is
=> AT = 18.
Then we need to find the length of the segment CA,
By subtracting the length of AT from the total length CT,
That is,
=> CA = CT - AT
Apply the values,
=> CA = 25 - 18
=> CA = 7.
Therefore, the length of the segment CA is 7.

Answer: -sinx
the derivative of f(x)f(x) with respect to x is the function f′(x)f′(x) and is defined as,
f’(x) = lim h tends to 0 [ f(x + h) – f(x) / h ]
A function f(x)f(x) is called differentiable at x=ax=a if f′(a)f′(a) exists and f(x)f(x) is called differentiable on an interval if the derivative exists for each point in that interval.
y = cos(x) + a^3
differentiating both sides with respect to x
dy / dx = d/dx (cosx) + d/dx (a^3)

If the volume of the cone is 96 cm^3 and the radius is 6 cm then the height of the cone is equal to 2.55 cm.
The height of the cone can be defined as the extent of the altitude of the cone. The height of a cone can be determined using its volume and radius values. The formula for the volume of a cone can be given as:
V= πr²h/3
Here, V is the volume of the cone, r is the radius of the cone and h is the height.
This equation can be rearranged to find the value of height as follows,
h=3V/πr²
Now, add the given values to the equation,
h= 3(96)/π(6²)
h= 288/π(36)
As π = 3.14
h= 288/3.14(36)
h= 288/ 113.04
