The selling price is $224.75.
What is Percent?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Cost price= $155
Cost marks up = 45%
Then the selling price is
=155 + 155 x 45/100
= 155 + 155 x 0.45
=155 + 69.75
= $224.75
Hence, The selling price is $224.75.

Circle the whole numbers and explain the reasoning : 9, 4/4, and 1.00000
Answer:
9, 4/4, and 1.00000
Explanation:
Whole numbers are the basic counting numbers 0,1,2,3,4,...There is no fractional or decimal part. And no negatives.
Given the numbers:
• Firstly, 9 is clearly a whole number
,• 4/4 = 1. 4/4 is a fraction that is equivalent to a whole number. Therefore, it is a whole number.
,• 1.00000=1. Whenever there is a decimal in which all the digits after the decimal point are zeros, the number is a whole number.
The function f(x) = 1(3)x models the number of virus cells present in a sample after x minutes. About how many cells will be present after 1 1/2 minutes? (round to the nearest whole number)
Answer:
The number of cells that will be present is;
[tex]5\text{ cells}[/tex]Explanation:
Given that the function f(x) models the number of virus cells present in a sample after x minutes.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.
What is an angle?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.
Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius. The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.

A standard die is rolled. Find the probability that the number rolled is odd.
Answer
Explanation
To determine the probability that the number rolled is odd using a standard die, we first list the total outcomes as shown below:
1,2,3,4,5,6
As we can see, the odd numbers are:
1,3,5
This means that the total favorable outcomes is 3.
Now, we use the formula:
[tex]Probability=\frac{favorable\text{ outcomes}}{Total\text{ outcomes}}[/tex]We plug in what we know:
[tex]\begin{gathered} Probab\imaginaryI l\imaginaryI ty=\frac{favorable\text{ outcomes}}{Total\text{ outcomes}} \\ =\frac{3}{6} \\ Simplify \\ Probab\mathrm{i}l\mathrm{i}ty=\frac{1}{2} \end{gathered}[/tex]Therefore, the probability that the number rolled is odd is 1/2.
Answer:
3/6
A standard die has 6 sides, numbered 1 through 6 (1,2,3,4,5,6). That means we have 3 odd numbers (1,3,5) and 3 even numbers (2,4,6).
The total possible outcomes of an odd number are 3, because there are 3 odd numbers, and the total outcomes are 6. So we write it as 3/6, like 3 out of six chances of getting an odd number.
It can be simplified to 1/2.

A retailer is looking to evaluate its customer service. Management has determined that if the retailer wants to stay competitive, then it will have to have at least a 90% satisfaction rate among its customers. Management will take corrective actions if the satisfaction rate falls below 90%. A survey of 1,200 customers showed that 1,068 were satisfied with their customer service.
Answer:
They have an 89% satisfaction rate, less than the goal.
Step-by-step explanation:
To find this, divide 1068/1200, this gives you 0.89
This shows that they have an 89% satisfaction rate.
Since, the satisfaction rate 89% which is less than 90%. Therefore, management will take corrective actions.

Step-by-step explanation:
Micaela is working two summer jobs, making $13 per hour tutoring and making $10
per hour landscaping. In a given week, she can work at most 13 total hours and must
earn a minimum of $140. If a represents the number of hours tutoring and y
represents the number of hours landscaping, write and solve a system of inequalities
graphically and determine one possible solution.
The equations will be a+ y ≤ 13, since Micaela can't work more than 13 hours and also she needs to earn at least $140 each week, so other equation will be 13a + 10y ≥ 140.
What is inequalities?Inequality, a declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
a = number of hours spent tutoring
y = number of hours spent landscaping
Micaela can't work more than 13 hours, so a + y ≤ 13.
Also, she needs to earn at least $140 each week, so 13a + 10y ≥ 140.
Using intercepts, you may graph things in this format on paper. They must be transformed into slope-intercept form in order to be graphed on a standard graphing calculator.
For instance, if a = 12 and y = 2, then a + y = 13 hours, and 12(13) + 2(10) = $176. Micaela puts in her maximum number of hours and earns more than she should.

Answer:
Either of ...
reflection across the y-axis, and translation down 6reflection across the x-axis and translation down 4Step-by-step explanation:
You want the transformations that take f(x) = 3x+1 to g(x) = -3x-5.
TransformationThe x-term of the transformed function has a sign opposite that of the original function. That can be accomplished by either of (a) reflection across the y-axis (replaces x by -x), or by (b) reflection across the x-axis (replaces f(x) by -f(x)).
Either way, an additional translation is required. That translation can be either vertical or horizontal, and may be done either before or after the reflection.
Horizontal reflectionReflecting f(x) across the y-axis means it becomes ...
f(-x) = 3(-x) +1 = -3x +1
In order to make that into -3x-5, we must add -6 to the function value:
g(x) = f(-x) -6 = (3(-x)+1) -6 = -3x -5
F(x) will be taken to g(x) = -3x-5 by reflection across the y-axis and translation down 6 units.
Vertical reflectionReflecting f(x) across the x-axis means it becomes ...
-f(x) = -(3x +1) = -3x -1
In order to make that into -3x-5, we must add -4 to the function value:
g(x) = -f(x) -4 = -(3x +1) -4 = -3x -5
F(x) will be taken to g(x) = -3x-5 by reflection across the x-axis and translation down 4 units.
__
Additional comment
As noted above, the translation can be either horizontal or vertical. For example, translating the function 2 units to the right makes it f(x-2). Then reflection across the y-axis replaces x by -x, so we have ...
g(x) = f(-x-2) = 3(-x-2)+1 = -3x -6 +1 = -3x -5
To get g(x), we could translate right 2 units, then reflect across the y-axis.
We also note that point (-1, -2) is shared by f(x) and g(x), so reflection horizontally across the line x=-1, or vertically across the line y=-2 would also give the required transformation.
By applying the elimination method, solve the following pair of simultaneous equations:
− 2 = 4
4 + 2 = 6
By applying the elimination method the value of x is - 2 and y is 7.
This is a problem from algebraic equations and we have to apply the elimination method. We can solve this problem by following a few steps.
So, the given equation according to the question is,
− 2x = 4 ................ ( equation 1 )
4x + 2y = 6 ............... ( equation 2 )
While applying the elimination method we have to multiply equation (1) with the positive coefficient of x in the second equation and vice versa.
Here the coefficient of x in the first equation is 2 and in the second equation is 4.
Now, we have to multiply equation ( 1 ) with 4 and equation ( 2 ) with 2.
Therefore,
− 2x = 4 ................ ( equation 1 ) × 4
4x + 2y = 6 ............... ( equation 2 ) × 2
Now, we can rewrite the equations as,
− 8x = 16 .................. ( equation 3 )
8x + 4y = 12 .................. ( equation 4 )
Now the coefficient of x in both equations are same but opposite sign. So, we have to add the equations.
Here we get , -8x + 8x + 4y = 16 + 12
Or, 4y = 28
Or, y = 7
Now, we have to put the value of y in any equation.
4x + 2.7 = 6 ( equation 2 )
Or, 4x = 6 - 14 = -8
Or, x = -2
