Answers
Answer:
Negative, Positive, Negative, Positive
Step-by-step explanation:
1. 18.75 + (-19)
Adding a negative is the same as subtracting. 18.75 - 19 is -0.25 so the first answer is negative.
2. \(-3 \frac{7}{10}\) + \(3\frac{4}{5}\)
If you convert the fraction in the second term to one with the same denominator (three and 8 10ths), you can see that since 8 tenths is more than 7 tenths, the equation will result in positive 1/10
3. 9.4 + (-\(9\frac{3}{5}\))
3/5 is the same as 6/10 or .60
9.6 is more than 9.4, so the negative is further from zero than the positive.
4. -7 + 7 + 1/2
-7 + 7 is zero. zero + 1/2 is positive 1/2

Given distinct noncollinear points A, B, and C, the set of all points between 1 point
A and C, including A and C is
A ray A circle An angle A line segment
Answers
Points that are not on the same line are said to be noncollinear.
The set of points between A and C is a line segment.
From the question, we understand that A, B and C are not on the same line.
We do not know if the distance between AB is the same as the AC and BC, so the set of points cannot be a circle.
For the set of points to be an angle, it must pass through A, B and C.
Since it only passes through A and C, the set of points cannot be an angle.
A ray has only one endpoint, so the set of points cannot be a ray.
A line segment has two endpoints;
Since the points are between A and C, we can consider A and C as the endpoints of the line.
Hence, the set of points between A and C is a line segment.

Answers
The solution to the equations are b = 15, b = 22, c = 21 and n = 28
How to determine the solution to the equationsFrom the question, we have the following equations that can be used in our computation:
31 - b = 16
28 + b = 50
33 + c = 54
52 - n = 24
Next, we collect the like terms in each of the equation
This gives
b = 31 - 16
b = 50 - 28
c = 54 - 33
n = 52 - 24
Lastly, we evaluate the like terms

The low temperature on new years day for five major cities were -12.5, -11.7,-12.4, -12.6, -12.3...on the same say the low temperature in Kansas city was warmer than Chicago but colder than New York
Answers
The average temperature in the five major cities was colder than in both Kansas City and New York.
We have,
We are not given the temperature in Kansas City and New York, but we know that Kansas City was warmer than Chicago and colder than New York.
Therefore, we can say that the temperature in Chicago was between the temperature in Kansas City and the temperature in New York.
Let's find the average temperatures in the five major cities:
average temperature
= (-12.5 - 11.7 - 12.4 - 12.6 - 12.3)/5
= -12.5
This means that the average temperature in the five major cities was -12.5 degrees Celsius.
Since we don't know the specific temperatures in Kansas City and New York, we cannot say for sure whether the temperature in Kansas City was warmer than in New York.
However, we can say that the average temperature in the five major cities was colder than in both Kansas City and New York.
Thus,
The average temperature in the five major cities was colder than in both Kansas City and New York.

Answers
The solution of a system of equations in the point of intersection of the two lines.
In this case we don't have the point of intersection at first but we notice that the lines are not parallel, hence they have to intersect in some point. To find the intersection we expand the lines in the grid (that is, we continue both lines in both directions). If we do that we get:
Once we find the intersection of both lines we find its coordinates.
Therefore, the solution of the system is the point (-5,-4).

In this case, the width is x^2 inches, the length is xy^2 inches, and the height is xy inches.
Substituting these values into the formula, we get:
V = (xy^2)(x^2)(xy)
Simplifying, we get:
V = x^4y^3

suppose you roll two six-sided dice. let the macrostate s of the two dice be the sum of their top faces.
Answers
The macrostate s of two six-sided dice can be defined as the sum of the top faces of the dice.
The macrostate of a system refers to a comprehensive description of the system in terms of its properties and variables that are used to characterize it. In the case of two six-sided dice, the macrostate is described by the sum of the numbers on the top faces of the two dice, which determines the total score or outcome. This macrostate, represented by the variable "s", is a measurable quantity that summarizes the state of the system, providing information about the distribution of the outcomes over all possible configurations of the two dice.
It's important to note that a macrostate does not specify the exact configuration of the system, but rather provides a probabilistic description of it. In other words, the macrostate "s" only describes the sum of the two dice and does not specify which number is on each die. In thermodynamics, macrostates are used to characterize the thermodynamic properties of a system, such as its temperature, pressure, and entropy. The study of macrostates and their distributions helps us to understand the behavior of complex systems and make predictions about their future behavior.

Answers
You must charge the customer to achieve your profit target it should be more than $328.
Given that, on a service call, your technician used one contractor the cost you $17.50.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Now,
Total cost = 17.50+6.75+134+11.5+3.5×28.20
= 169.75+98.7
= $268.45
22% net margin
So, 22% of 268.45
= 0.22×268.45
= $59.059
Final cost = 268.45+59.059
= 327.509
≈ $328
You must charge the customer to achieve your profit target it should be more than $328.

The perimeter of Max's sandbox is 21 feet.
What is perimeter of a figure?The sum of each length of external sides or boundary of a given figure is called its perimeter. To determine the perimeter of an object, add up the length of its boundaries.
Given the dimension of the Ohio park, then we have to determine the representative fraction of Max's sandbox.
Representative fraction = 10/ 25
= 2/ 5
So that;
x = 15 * 2/5
= 6 ft
y = 12.5 *2/5
= 5 ft
The perimeter of Max's sandbox = 10 + y + x
