in a certain clothing store, the ratio of the number of full-time employees to the number of employees who are not full-time is 1 to 4. if 5 more full-time employees were hired, the ratio would be 2 to 3. how many employees are employed by the store?
Answer: Total number of employees are employed by the store = 15 employees.
Step-by-step explanation:
The ratio of Full time employees to Not Full time employees would be 1 to 4.
Let, Full time employees F =1
Not Full time employees N =4
We can write:
F/N = ¼
Cross multiply to get:
N=4F
If 5 more Full time employees were hired, then the ratio would be 2 to 3.
This would be mean there are no (F+5) Full time employees.
Also there are still Not Full time employees.
We can write:
(F+5) / N = 2/3
Cross multiply to get:
3(F+5) =2N
Expand to get:
3F+15=2N
Replace N with 4F to get:
3F+15=2(4F)
Solve to get:
3F+15=8F
15=8F-3F
15=5F
F=3
So, there are presently 3 Full time employees.
How many employees does the store have?
Since F=3,
we can use the equation N=4F
To help find the value of N Replace F with 3 to get:
N = 4(3)
Solve to get:
N=12
So, Full time employees F=3
Not Full time employees N=12
Then, Total number of employees = F+N
= 3+12
= 15.
Hence, Total number of employees = 15 employees.

Simplify the expression by combining like terms:
Answer:
2b² + 2b
Step-by-step explanation:

Answer:
[tex] \sf \: {2b}^{2} + 2b [/tex]
Step-by-step explanation:
Given expression,
→ b + 3b² + b - b²
Let's simplify the expression,
→ b + 3b² + b - b²
→ (3b² - b²) + (b + b)
→ (2b²) + (2b)
→ 2b² + 2b
→ 2b(b + 1)

What is the distributive property?The distributive property states that for an expression a(b + c), it can be evaluated to ab + ac.
SolveTo distribute, expand the algebraic expression using the aforementioned policy.
[tex]-6(a+8)[/tex]
Multiply a and b together.
[tex]-6\times a=-6a[/tex]
Then, multiply a and c together.
[tex]-6\times8=-48[/tex]
Finally, add the two values together.
[tex]-6a+(-48)=-6a-48[/tex]
Final Answer[tex]\boxed{\bold{-6a-48}}[/tex]
Hey there!
Distributive Property formula:
a(b + c)
= a(b) + a(c)
= a * b + a * c
= ab + ac
Your equation: -6(a + 8)
Solving:
-6(a + 8)
= -6(a) - 6(8)
= -6 * a - 6 * 8
= -6a - 48
Therefore, your answer should be:
-6a - 48

10 feet above sea level. What is the difference in elevation between the bottom of the canyon and the bird's nest?
The difference in the elevation between the canyon and the bird's nest is 737. 3 feet
How to determine the value
From the information given, we have that;
The distance below the sea level = 52 3/ 5 feet , this would take a negative valueThe distance above sea level = 789 3/ 10, this would take a positive valueLet's convert the mixed fractions to improper fraction;
= - 263/ 5 = - 52. 6 feet
789 3/ 10 = 7893/ 10 = 789. 3 feet
The difference in the elevation between the canyon and the bird's nest ;
= -52. 6 + 789. 9
= 737. 3 feet
Thus, the difference in the elevation between the canyon and the bird's nest is 737. 3 feet

The highest recorded temperature on earth is 134 degrees fahrenheit. the lowest is -128.6 degrees fahrenheit. what is the difference between these temperatures?
The difference between the highest recorded temperature on Earth of 134 degrees Fahrenheit and the lowest recorded temperature of -128.6 is equal to 262.6 degrees Fahrenheit.
In mathematics, the difference can be described as the result of the subtraction of one numeral or value to another.
Hence the difference between the highest recorded temperature and the lowest recorded temperature on Earth can be found by the subtraction of the highest and lowest recorded temperatures.
The difference in the two temperatures = highest recorded temperature - lowest recorded temperature
Difference in Farenheit = 134 - ( -128.6)
Difference in Farenheit = 134 + 128.6
Difference in Farenheit = 262.6
Hence, the difference between the highest recorded temperature and the lowest recorded temperature is calculated to be 262.6 degrees fahrenheit.

Answer:
[tex]\mathrm{Focus:\;\;} \left(-\frac{5}{3},\:2\right)[/tex]
[tex]\mathrm{Directrix:\;\;}x=-\frac{1}{3}[/tex]
Step-by-step explanation:
The standard equation for a parabola is
[tex]4p\left(x-h\right)=\left(y-k\right)^2[/tex]
with vertex at (h, k) and a focal length of |p|
[tex]\mathrm{Rewrite}\:x=-\frac{3}{8}\left(y-2\right)^2-1\:\mathrm{in\:the\:standard\:form}[/tex]:
[tex]\mathrm{Add\:}1\mathrm{\:to\:both\:sides}[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}-\frac{3}{8}[/tex]
[tex]\frac{x+1}{-\frac{3}{8}}=\frac{-\frac{3}{8}\left(y-2\right)^2}{-\frac{3}{8}}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]-\frac{8x}{3}-\frac{8}{3}=\left(y-2\right)^2[/tex]
[tex]\mathrm{Factor\:}-\frac{8}{3}[/tex]
[tex]\left(-\frac{8}{3}\right)\left(x+\frac{-\frac{8}{3}}{-\frac{8}{3}}\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]\left(-\frac{8}{3}\right)\left(x+1\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{Factor\:}4[/tex]
[tex]4\cdot \frac{-\frac{8}{3}}{4}\left(x+1\right)=\left(y-2\right)^2[/tex]
[tex]\mathrm{Simplify}[/tex]

[tex]\mathrm{We\; can\; rewrite\:this\;as}[/tex]
[tex]4\left(-\frac{2}{3}\right)\left(x-\left(-1\right)\right)=\left(y-2\right)^2[/tex]
Comparing this with the standard form we get
[tex]\left(h,\:k\right)=\left(-1,\:2\right)[/tex]
[tex]\:p=-\frac{2}{3}[/tex]
The parabola is symmetric around the x-axis.
The focus lies a distance [tex]p[/tex] from the center [tex]\left(-1,\:2\right)[/tex] along the x axis
So focus is at
[tex]\left(-1+p,\:2\right)[/tex] [tex]=\left(-1+\left(-\frac{2}{3}\right),\:2\right)[/tex] [tex]=\bold{ \left(-\frac{5}{3},\:2\right)}[/tex]
The parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis at a distance -p from the center
[tex]x=-1-p[/tex]
[tex]x=-1-\left(-\frac{2}{3}\right) = \bold{-\frac{1}{3}}[/tex]

Step-by-step explanation:
1. Needed points is 184 and rewards points was 70
2. So he need extra 114 points for free movie ticket
3. 114 divide by 9.5 which is earn piont for every time he buy ticket
The equation 70 + 9.5x = 184 represents the situation and the number of visits is 12 if Marques has a points card for a movie theater.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Marques has a points card for a movie theater. • He receives 70 rewards points just for signing up
Let x be the number of visits.
The linear equation can be framed as follows:
70 + 9.5x = 184
9.5x = 184 - 70
After solving the above linear equation in one variable:
9.5x = 114
x = 12
Thus, the equation 70 + 9.5x = 184 represents the situation and the number of visits is 12 if Marques has a points card for a movie theater.

A translation along the directed line segment NB then a reflection over the vertical line about B so sequence A is correct therefore option (A) will be correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the triangle MNO and ABC
Now,
If we translate MNO along the directed line segment NB and reflect over B then M will coincide with A and N with B and O with C.
In sequence B if we reflect on MO then M will not coincide with A and it will not form a triangle ABC.

how many ways can a parent distribute five one-dollar bills to her three children? (b) how many ways can she accomplish this if each child gets at least one dollar?
By the concept of Permutations and Combinations, we get:
Number of ways to distribute 5 dollar bills among three children = 21
and
Number of ways to distribute 5 dollar bills such that each child gets at least one dollar = 6
What is permutations and combinations?A permutation is an orderly arrangement of the items or numbers. Combinations are a means to choose items or numbers from a collection or set of items without regard for the items' chronological sequence.Given:
Number of 1 dollar bills = 5Number of children = 3To find: (A) number of ways to distribute the dollar bills among the children
(B) number of ways to do the same if each child gets at least a dollar.
Finding:
By using the formula: [tex]\binom{n+r-1}{r-1}[/tex],
Number of ways to distribute 5 dollar bills among three children = [tex]\binom{5+3-1}{3-1} = \binom{7}{2}= \frac{7\times6}{2}[/tex] = 21 ways.
Similarly, upon modifying the above formula as: [tex]\binom{n-1}{r-1}[/tex],
