A person is to install five devices each 6 7/8 inches wide with 3 1/2 inches between switches. how much space will be needed to mount these switches?
Answers
w = 6 7/8 in = 6.875 in, the width of each device.
d = 3 1/2 in = 3.50 in, the space between teo devices.
The total space needed is
D = 4(w+d) + w
= 5w + 4d
= 5*6875 + 4*3.5
D = 48.375 in or 48 3/8 in
Answer: 48 3/8 inches or 48.375 inches

Answer:
The dimension of the rectangle is [tex]16\times 17\times 18[/tex]
Step-by-step explanation:
Given : The dimensions of a rectangular bin are consecutive integers. If the volume of the bin is 4896 cubic inches.
To find : What are the dimensions of the bin?
Solution :
The dimensions of a rectangular bin are consecutive integers.
Let the consecutive integers are x,x+1,x+2
So let, length, l=x
Breadth b=x+1
Height h=x+2
The volume of the bin is
[tex]V=l\times b\times h[/tex]
[tex]4896=x\times (x+1)\times (x+2)[/tex]
[tex]4896=(x^2+x)(x+2)[/tex]
[tex]4896=x^3+2x^2+x^2+2x[/tex]
[tex]x^3+3x^2+2x-4896=0[/tex]
Plot the equation graphically to find the value of x.
Refer the attached figure below.
The value of x is 16.
So, Length is l=16
Breadth is b=x+1=16+1=17
Height is h=x+2=16+2=18
The dimension of the rectangle is [tex]16\times 17\times 18[/tex]

Point Q is the midpoint of GH. GQ=2x+3, and GH=5x−5 .
What is the length of GQ?
Enter your answer in the box.
____ units
Answers
The length of GQ is 25/3 units.
Explanation:To find the length of GQ, we need to equate GQ to GH and solve for x. Since Q is the midpoint of GH, the lengths GQ and QH are equal. Therefore, we have the equation:
2x + 3 = 5x - 5
Subtract 2x from both sides:
3 = 3x - 5
Add 5 to both sides:
8 = 3x
Divide both sides by 3:
x = 8/3
To find the length of GQ, substitute the value of x back into 2x + 3:
GQ = 2(8/3) + 3
GQ = 16/3 + 3
GQ = 16/3 + 9/3
GQ = 25/3 units
which shows the set(s) the number 2.77 is an element of?
Answers
2.77 is not a natural number (counting numbers 1, 2, 3, ...)
2.77 is not a whole number (non-negative integers 0, 1, 2, 3, ...)
2,77 is not an element of null set as a null set has no elements.
{5, 7, 9}
The elements 5, 7 and 9 are elements of set D and they are also elements of set E.
The correct answer is option a. 2.77 is an element of the set real numbers.
To determine which set(s) the number 2.77 is an element of, let's analyze each option:
1. Real numbers: The set of real numbers includes all rational and irrational numbers. This means any number that can be placed on the number line, including integers, fractions, and decimals. Since 2.77 is a decimal number, it is indeed a real number.
2. Real numbers and natural numbers: While 2.77 is a real number, natural numbers are a subset of real numbers that consist of all positive integers (1, 2, 3, ...). Since 2.77 is not a positive integer, it is not a natural number. Therefore, this option is incorrect because 2.77 is not a natural number.
3. Natural numbers and whole numbers: As mentioned, natural numbers are positive integers. Whole numbers include all natural numbers and the number 0 (0, 1, 2, 3, ...). Since 2.77 is neither a natural number nor a whole number, this option is incorrect.
4. Null set: The null set (or empty set) contains no elements. If 2.77 were in the null set, it would imply that the null set is not empty, which contradicts the definition of the null set. Therefore, this option is incorrect.
The complete question is
"Which shows the set(s) the number 2.77 is an element of?
a. real numbers
b. real numbers and natural numbers
c. natural numbers and whole numbers
d. null set"

Answer:
(2x + 1) - (–x² + 3x) is difference .
Step-by-step explanation:
Given : r(x) = –x² + 3x and s(x) = 2x + 1
To find : Find the difference of functions s and r .
Solution : We have given that r(x) = –x² + 3x and s(x) = 2x + 1.
Difference :
(s – r)(x) = s(x) - r(x)
=(2x + 1) - (–x² + 3x)
= 2x +1 + x²-3x
= x²-x +1.
Therefore, (2x + 1) - (–x² + 3x) is difference .
The difference of the function is (2x+1)-(x^2 + 3x)
Difference of functions
Given the following functions
r(x) = –x² + 3x
s(x) = 2x + 1
Taking the difference of the function will give:
(s – r)(x) = 2x - 1 - (-x^2 + 3x)
Expand
(s – r)(x) = 2x - 1 + x^2 - 3x
(s – r)(x) = x^2 - x - 1
Hence the difference of the function is (2x+1)-(x^2 + 3x)

Your gross weekly salary is $800.00. Your federal income tax deduction is $53. The Social Security tax is 6.2%. The Medicare tax is 1.45% of gross pay. The state tax is 1.5% of gross pay. Each week you have $28.40 deducted for medical insurance and $12.00 for a health savings account. What is your net pay?
Answers
The net weekly pay is $633.4
How to determine the net pay?The gross pay is given as:
Gross = $800.00
The deductions are:
Federal income tax deduction = $53.Social Security tax = 6.2%. Medicare tax = 1.45%State tax = 1.5%Medical insurance = $28.40Health savings account = $12.00The net pay is then calculated as:
Net pay = 800.00 - (53 + 6.2% * 800 + 1.45% * 800 + 1.5% * 800 + 28.40 + 12.00)

The stage manager of a school play creates a rectangular acting area of 42 square yards. String lights will outline the acting area. To the nearest whole number, how many yards of string lights does the manager need to enclose this area?
Answers
Let the length of the rectangular acting area be x, then the width is given by 42 / x.
The number of yards of string lights that the manager need to enclose the area is given by the perimeter of the rectangular area.
Recall that the perimeter of a rectangle is given by
P = 2(length + width) = 2(x + 42/x) = 2x + 84/x
The perimeter is minimum when the differenciation of 2x + 84/x is equal to 0.
i.e. [tex]2 - \frac{84}{x^2}=0\\ \\ \Rightarrow2x^2-84=0\\ \\ \Rightarrow x^2=42\\ \\ \Rightarrow x\approx6.48[/tex]
Therefore, the minimum number of yards of string lights the manager need to enclose this area is given by
[tex]2(6.48)+ \frac{84}{6.48} =12.96+12.96=25.92\approx26\ yards[/tex]

Determine the axis of symmetry and the vertex of the given function. y = 2x2 − 12x + 21 Axis of symmetry: x = Vertex: ( , )
Answers
Answer:
The vertex of the function is (h,k)=(3,3)
The axis of symmetry is x=3.
Step-by-step explanation:
Given : Function [tex]y=2x^2-12x+21[/tex]
To find : Determine the axis of symmetry and the vertex of the given function.
Solution :
The quadratic function is in the form, [tex]y=ax^2+bx+c[/tex]
On comparing, a=2 , b=-12 and c=21
The vertex of the graph is denote by (h,k) and the formula to find the vertex is
For h, The x-coordinate of the vertex is given by,
[tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{-12}{2(2)}[/tex]
[tex]h=\frac{12}{4}[/tex]
[tex]h=3[/tex]
For k, The y-coordinate of the vertex is given by,
[tex]k=f(h)[/tex]
[tex]k=2h^2-12h+21[/tex]
[tex]k=2(3)^2-12(3)+21[/tex]
[tex]k=18-36+21[/tex]
[tex]k=3[/tex]
The vertex of the function is (h,k)=(3,3)
The x-coordinate of the vertex i.e. [tex]x=-\frac{b}{2a}[/tex] is the axis of symmetry,
So, [tex]x=-\frac{b}{2a}=3[/tex] (solved above)
So, The axis of symmetry is x=3.
The ages of mark and adam add up to 28 years total. mark is 20 years older than adam. how many years old is adam
Answers
Eqn 1: x + y = 28
Eqn 2: x = 20 + y
Subsituting Eqn 2 to Eqn 1,
20 + y + y = 28
2y = 28 - 20 = 8
y = 8/2 = 4
Therefore, Adam is 4 years old.
Adam is 4 years old. This conclusion is reached by setting up a system of equations based on the information that Mark and Adam's ages add up to 28 years and Mark is 20 years older than Adam.
The student is asking how old Adam is, given that the total age of Mark and Adam is 28 years, and Mark is 20 years older than Adam. To solve this, we can set up a system of equations. Let Mark's age be represented by M and Adam's age be represented by A. The two equations based on the given information would be:
M + A = 28 (The sum of their ages is 28)M = A + 20 (Mark is 20 years older than Adam)Now, substituting the second equation into the first one, we get:
A + 20 + A = 28
This simplifies to:
2A + 20 = 28
Subtracting 20 from both sides, we have:
2A = 8
Dividing both sides by 2, we find:
A = 4
So, Adam is 4 years old.
