I seriously need help on this question, can someone help?
Answer:
a. A + C < B + C
Step-by-step explanation:
when we know that A < B, then adding the same amount to both sides did not change the relationship between both sides.
this is like having a balance with 2 cups. one side is heavier than the other, so the heavier cup is down.
if we add the same weight to both cups, the situation will not change.
that is why a. is the right answer.
b. would only be right, if C is negative.
for positive C the same argument as for A applies. a smaller amount (or weight) stays smaller also after multiplying both sides by the same number.
but because this option would only be right for a subset of the possible values, this is not true in general.
c.
this is not true at all.
if we multiply the expression by -1, then the inequality sign has to flip. < becomes >, > becomes <.

you want to sell 1/lb jars of mixed peanuts and cashews for five dollars . you paid three dollars per pound for peanuts and six dollars per pound of cashews . you plan to combine four parts peanuts and one part cashews to make your mix . you have spent $70 on materials to get started . how many jars must you sell to break even ?
Answer:
To calculate the number of jars you need to sell to break even, we can use the following formula:
(Cost of materials + Cost of ingredients per jar) / Price per jar = Number of jars needed to break even
We know that the cost of materials is $70, the cost of ingredients per jar is $18 ( $12 for peanuts + $6 for cashews) and the price per jar is $5.
Plugging in these values into the formula we get:
($70 + $18) / $5 = (88/5) = 17.6 jars
So, you need to sell at least 17.6 jars to break even.
--------------------
Cost of materials / (Price per jar - Cost of ingredients per jar) = Number of jars needed to break even
We know that the cost of materials is $70, the cost of ingredients per jar is $18 ( $12 for peanuts + $6 for cashews) and the price per jar is $5.
Plugging in these values into the formula we get:
$70 / ($5 - $18) = 70 / -13 = -5.38 jars
It is not possible to sell -5.38 jars, which means you are making a loss. This indicates that your cost of materials and ingredients is higher than the price you are selling the jars for. To break even, you will have to lower your costs or increase the price of the jars.

When using substitution to solve a linear system how do you know if the system is inconsistent?.
The first step in determining whether a linear system is inconsistent is to identify whether the lines are parallel. Check to see if the lines have a y-intercept in common, if so.
This result establishes an inconsistent system due to the fact that two parallel lines with distinct y-intercepts will never intersect.
If there is at least one solution to a linear equations system, it is said to be a consistent system. The system is regarded as inconsistent if there is no solution.
When the lines are parallel to one another, a system of linear equations cannot become inconsistent in any other way. The slope of parallel lines is the same. Therefore, comparing the slopes is a good way to ascertain whether the system is inconsistent. The comparison is simple if the linear equations are written in the point-slope or slope-intercept form. In order to determine the coefficient of x and compare slopes, it is a good idea to solve for y on all equations that are in a different form and express them in the slope-intercept form. The equation system is inconsistent if the slopes are equal to one another.

Write the equation of the hyperbola with centre at (4, 2), vertex at (4, 5), one asymptote with equation 4y - 3x = -4.
x2a2y2b2=1 x 2 a 2 y 2 b 2 = 1 is the conventional form of a hyperbola equation with the origin as the center and the vertices (a,0) (a, 0) and co-vertices (0b), (0b).
How do you find the equation of a hyperbola given center and vertex?A right circular cone and a plane are intersected at an angle that intersects both of the cone's halves to create a hyperbola in analytic geometry. There are two distinct unbounded curves that result from this intersection, and they are mirror reflections of one another.The set of all points (x, y) in a plane that are part of a hyperbola has a positive constant as the difference between their distances from the foci.Every hyperbola, like the ellipse, has two axes of symmetry. A line segment called the transverse axis, which has vertices for endpoints and runs through the hyperbola's centre. On the transverse axis-containing line, the foci are located. The co-vertices serve as the endpoints of the conjugate axis, which has a perpendicular relationship to the transverse axis. When the transverse and conjugate axes connect, they form the centre of a hyperbola. Two asymptotes also cross the centre of every hyperbola. The asymptotes of a hyperbola's branches are as it moves out from its center.When graphing the hyperbola and its asymptotes, the central rectangle of the hyperbola, whose sides run across all of its vertices and covertices and are centred at its origin, is a valuable tool. Simply draw and extend the diagonals of the central rectangle to represent the hyperbola's asymptotes.The axes in this section will either be on or be parallel to the x- and y-axes, and we will focus on hyperbolas that are positioned vertically or horizontally in the coordinate plane. The two situations that we'll look at are those that have the origin as their centre of gravity and those that have it somewhere else.The Complete Question is hyperbola equation.

How much is a 90 angle?.
A 90-degree angle, also known as a right angle, is an angle that measures exactly 90 degrees.
A 90-degree angle is an angle that measures exactly 90 degrees. It is also known as a right angle, since it is an angle that forms a right angle.
In geometry, angles are measured in degrees, and a full rotation is equal to 360 degrees. The angle formed by two intersecting lines is measured by the amount of rotation needed to bring one line to overlap the other. A 90-degree angle is formed by rotating one line by exactly 90 degrees, so that the two lines form a right angle.
A right angle is an angle that measures 90 degrees and it is represented by a small square at the angle's vertex. This square is a symbol of the angle's measure. In addition, the right angle is the only angle that can be used in geometry to create perpendicular lines which are lines that meet at 90 degrees.
In real-world applications, right angles are found in many things such as the corners of a room, the corners of a square or rectangle, and the corners of tools like a square, a ruler, and a protractor.
Therefore, In short, a 90-degree angle, also known as a right angle, is an angle that measures exactly 90 degrees. It's represented by a small square at the angle's vertex, and it's the only angle that can be used in geometry to create perpendicular lines.

Suppose you through a ball horizontally. How is the way the ball moves similar to the motion of the planets around the sun?
The forces acting on a horizontally moving ball in the air are gravity or the force of its own weight, and the force that displaces the ball in the horizontal direction.
What is force?Force is an external agent that acts on a body to cause it to move or stop. There are various types of forces, such as magnetic forces, nuclear forces, frictional forces, and so on.
The product of a moving body's mass and acceleration yields force, which is derived from Newton's second law of motion. As a result, as the mass of the object increases, the force required to change its state increases.
The forces acting on a moving ball horizontally are the normal force that displaces it in that direction and the downward force of gravitation equal to its weight. Air resistance acting on the ball can also be considered.

A worker spent 2 hours and 40 minutes making 20 products. If he works at the same productivity, how long will it take the worker to make 30 units?
Answer:
Step-by-step explanation:
The Time Taken to make 20 products = 2hours and 40 minutes = 160 minutes
Time taken to make 10 units = 80 minutes
Time taken to make 30 units = time taken to make 20 units + time taken to make 10 units
= 160 minutes + 80 minutes
= 240 minutes or 4 hours.
The worker needs 4 hours to make 30 units.
The ratio can be calculated as follows:
The first is to convert hours to minutes
2 hours 40 minutes = (2×60)+40 = 120+40 = 160 minutes
The next step is to compare worth comparison
[tex]\frac{a1}{b1}[/tex] = [tex]\frac{a2}{b2}[/tex]
[tex]a_{1} = 160 minutes\\a_{2} = X\\b_{1} = 20 products\\b_{2} = 30 products[/tex]
So,
[tex]\frac{160}{20} = \frac{X}{30}[/tex]
X = [tex]\frac{(160.30)}{20}[/tex]
X = [tex]\frac{4800}{20}[/tex]
X = 240 minutes
The next is to convert minutes into hours
240 minutes ÷ 60 minutes
= 4 hours

The two adjacent columns that show an interval with an average rate of change of -0.3 are column 7ᵗʰ and 8ᵗʰ.
We have a function used by an architect is designing a water fountain for a park. The function is defined as h(x) = - x²/20 + x + 15
where h(x) --> height of the water jet, in feet,
x --> distance from its starting point in feet.Also , the average rate of change = - 0.3
Average rate of change is used to measure the change in value of function per unit, on average over an interval. It is derived from the slope line which is formed bu joining the end points of graph. Formula is represented as
A(x) = {F(b) - F(a)}/(b - a)
where b and a are end points of interval.
In this case, this formula is used as
A(x) = {H(x₂) - H(x₁)}/(x₂ - x₁ )
=> -0.3 = {H(x₂) - H(x₁)}/(x₂ - x₁ )
As we see in above figure the difference between the any two values of x is equals to 2 i.e., the final value - initial value = 2 in an interval.
So, x₂ - x₁ = 2
=> -0.3 = {H(x₂) - H(x₁)}/2
=> -0.3× 2 = H(x₂) - H(x₁)
=> -0.6 = H(x₂) - H(x₁)
=> H(x₂) = H(x₁) - 0.6
so, the columns which follows this relationship are the following
distance , x 12 14
Height of jet , h(x) 19.8 19.2
Hence, the required relationship is H(x₂) = H(x₁) - 0.6.

A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is more than two thousand years vintage, having been defined on the first actual page of Euclid's elements.
In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.

Can someone help me with this please?
Pleas show steps.
Solving the system of equations:
x + y = 45
y = 2x
We can see that he made a total of 30 hot dogs and 15 hamburgers.
How to write and solve the system of equations?We can define the variables:
x = number of hamburgersy = number of hot dogs.We know that he cooked a total of 45 dishes, then we can write the equation
x + y = 45
And he cooked twice as many hot dogs as hamburgers, then we can write:
y = 2x
Then we can write a system of equations at:
x + y = 45
y = 2x
We can replace the second equation into the first one, then we have:
x + (2x) = 45
3x = 45
x = 45/3
x = 15
And the solution of y is:
y = 2x
y = 2*15 = 30
The solution of the system is:
x = 15
y = 30

The required perimeter of the polygon is 92 cm.
What is a polygon?Polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,
Examples of polygons, equilateral triangles, squares, pentagons etc
here,
∠B ≅ ∠C
tangent drawn from D = tangent drawn from B
tangent drawn from D = 11.5 cm
The perimeter of the polygon is given = as the sum of a tangent from all points
= 11.5 + 11.5 + 11.5 + 11.5 + 10.5 + 10.5 + 12.5 + 12.5
= 92 cm
Thus, the required perimeter of the polygon is 92 cm.

What is modulus of 4i?.
The modulus of the complex number 4i is 4.
Now, According to the question:
Consider the given number 4i .
The number is a complex number which is of the form z = x + iy .
We can write the above question as z = 4i where x = 0 and y = 4 . The modulus of the complex number is given by:
[tex]|z| =\sqrt{Re(z)^2+Im(z)^2}[/tex]
where real part is x and imaginary part is y. Hence the modulus of a complex number is :
[tex]|z| =\sqrt{0^2+4^2}[/tex]
[tex]|z| = \sqrt{16} \\[/tex]
|z| = 4
Hence the modulus of the complex number 4i is 4.
