Is 5.787787778... a rational or irrational number?
Explain.
Answer:
For a number to be rational, it must:
-terminate (0.5) or repeat (0.3333...)
-be able to be written as a fraction
If a number does not meet this criteria, then it is irrational. Thus, 5.787787778... is irrational.

Find the midpoint of the line segment joining the points (-3,-2) and (-7,5)
Answer:
The midpoint is (-5,1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
( -3+-7)/2 = -10/2 = -5
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
( -2+5)/2 = 3/2 = 1.5
The midpoint is (-5,1.5)

11. The news reports that today's high temperature is 16°F colder than
yesterday's high temperature. Yesterday's high temperature was -2°F.
a. Write an expression to represent today's high temperature.
b. Reasoning is today's high temperature positive or negative? Why?
The expression to represent today's temperature is given by
- 2°F - 16°F = - 18°F and todays high temperature is negative as the
temperature is colder.
Temperature is a numerical expression of how hot a substance or radiation is.
There are three different types of temperature scales: those that are defined by the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron, in a body, like the SI scale. Those that rely only on macroscopic properties and thermodynamic principles, like Kelvin's original definition of temperature. Those that are not defined by theoretical principles but rather by useful empirical properties of particulate matter.The temperature yesterday was -2°F . The temperature is colder today and by 16°F more cold.
Since colder temperature is denoted by negative sign and hotter temperature by the positive sign then when the temperature is colder today then we have to subtract the values to the given values.
Hence - 2°F - 16°F = - 18°F .
So todays high temperature will be a negative value.

The answer you are looking for is
Solution/Explanation:
First, writing out the equation,
3x+5=2x-2x+29.
Next, making the equation more simple by subtracting 2x-2x, which is 0,
3x+5=0+29.
3x+5=29.
Now, subtracting 5 from both sides of the equation,
3x+5-5=29-5.
3x=24.
Finally, dividing both sides of the equation by 3,
3x/3=24/3.
x=8.
So, therefore, the final answer is x=8.

state the domain: A= {(-3,2), (5,4), (7,-3)}
The required domain is [tex]\{-3,5,7\}[/tex].
Given:
A set of ordered pairs is:
[tex]A=\{(-3,2),(5,4),(7,-3)\}[/tex]
To find:
The domain of the given set of ordered pairs.
Solution:
Domain is the set of input values.
In the set of ordered pairs [tex](x,y)[/tex], then the set of all the [tex]x[/tex]-values is domain and the set of all the [tex]y[/tex]-values is range.
We have,
[tex]A=\{(-3,2),(5,4),(7,-3)\}[/tex]
In the above set of ordered pairs, the x-values are [tex]-3,5,7[/tex].
[tex]Domain=\{-3,5,7\}[/tex]
Therefore, the domain of the given set of ordered pairs is [tex]\{-3,5,7\}[/tex].

How do i reflect triangle ABC if A (2,3), B (1,1), C(4,-3) over the x axis. Also rotating the triangle 90 degrees clockwise about the origin.
9514 1404 393
Answer:
see attached. red = reflected; blue = rotated
Step-by-step explanation:
The relevant coordinate transformations are ...
(x, y) ⇒ (x, -y) . . . . . reflection over the x-axis
(x, y) ⇒ (y, -x) . . . . . rotation 90° CW
In the attached figure, the red triangle A'B'C' is reflected. The blue triangle A"B"C" is rotated.
__
Additional comment
Learning to visualize these transformations can take a little practice. It can help to draw the figure on a graph, trace it on another piece of paper or transparency, then move the copy to the new position relative to the old axes.
For reflection across the x-axis, the x-axis of the copy is aligned with the original, but the copy is flipped over so the old +y axis is aligned with the -y axis, and vice versa.
For rotation 90° CW, what was the +y axis becomes aligned with the +x axis, and what was the +x axis becomes aligned with the -y axis. That is, the figure is rotated 90° CW about the origin so anything in the first quadrant is moved to the 4th quadrant.

A fine jewelry store leased a space at the mall with a base rent of $1,800 a month, plus 4% of all sales over $200,000. If the gross sales were $325,000, what was the total amount of rent paid by Heinz Fine Jewelry at the end of the year?
Answer:
So, first, we have to establish how much the base rent ends up costing. So to find that, we do 1,800x12=21,600. So the base rent is $21,600. Then, we add the 4% of sales which is 125,000x0.04=5,000. So, we add $21,600 with $5,000 and we get a final answer of $26,600 owed at the end of the year :)

Anthony has a bank balance of $45. Sara has a bank balance of -$90. Sean has a bank balance of -$208. Marsha has a bank balance of $153. Which is the smallest debt?
9514 1404 393
Answer:
Marsha and Anthony
Step-by-step explanation:
Here a negative bank balance represents a debt. The larger the magnitude of the negative number, the more debt it represents. A positive bank balance corresponds to no debt.
Anthony and Marsha -- no debt . . . . smallest debt
Sara -- $90 in debt . . . . smallest non-zero debt
Sean -- $208 in debt
On those with non-zero debt, Sara has the smallest debt. Overall, Anthony and Marsha have the smallest debt: zero debt.
Find the value of x,
Answer: x = -7
Concept:
From the given graph, we can see that it is an isosceles triangle since the two base angles are congruent.
In geometry, an isosceles triangle is a triangle that has two sides of equal length.
If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.
Solve:
Given information
First Side = 7
Second Side = x + 14
Given expression deducted from the definition of an isosceles triangle
Second Side = First Side
Substitute values into the expression
x + 14 = 7
Subtract 14 on both sides
x + 14 - 14 = 7 - 14

Answer:
x = 6
Step-by-step explanation:
According to the rules of segment addition, AB+BC=AC.
Since the length of AB is x+5, length of BC is 2x+10, and total length of AC is 33, we can create the equation: (x+5) + (2x+10) = 33.
To solve, we combine like terms: 3x + 15 = 33.
Subtract 15 from both sides: 3x = 18.
Divide both sides by 3: x = 6.

Answer:
B c² = h² + b² -2bx +x²
Step-by-step explanation:
The square of the binomial can be expanded using the distributive property:
c² = h² +(b -x)²
c² = h² +(b -x)(b -x)
c² = h² +b(b -x) -x(b -x)
c² = h² +b² -xb -bx +x²
c² = h² +b² -2bx +x² . . . . . matches choice B
