What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts.
Or, A number which is expressed as a quotient is called fraction.
It can be written as the form of p : q, which is equivalent to p / q.
Given that;
Sally has completed 1/3 of her shift.
Jerry has completed 5/6 of his shift.
David has finished 1/2 of his shift.
Mona has 7/8 of her shift remaining.
Now,
Since, Mona has 7/8 of her shift remaining.
Hence, The time for Mona = 1 - 7/8
= 1/8
We make all the denominator equal by taking LCM of 3, 6, 2, 8.
Thus, LCM of [3, 6, 2, 8] = 24
Hence, Sally has completed 8/24 of her shift.
Jerry has completed 20/24 of his shift.
David has finished 12/24 of his shift.
Mona has completed 3/24 of his shift.
Clearly, Jerry completed the most work time.
Thus, Jerry completed the most work time.

Answers
How do I solve this
Answers
Since the complementary angle adds up to 90 degrees, we would add 55° and (3x + 8)° and set it equal to 90°.
55° + (3x + 8)° = 90°
Now, to find x, we simplify.
63 + 3x = 90
3x = 27
x = 9
So, x is 9 degrees.

your primary jobs gross income is 3468.73/month deductions are fica (7.65%) federal tax witholding (11.5%) and state tax withholding (7.8%) how much are your ficed expenses if they are 36% of your relized income
Answers
$1,388.65
$814.92
$912.21
$1,068.57
To get your realized income you: add your deductions which equals to a total of 26.95%.
Then you subtract that amount from your gross income.
(3468.72 - 26.95% = 2533.91)
After that you need to find what 36% of your realized income equals to:
and it equals to, 912.20.
Therefore, your answer is C.
Answer 2:
our deductions are 7.65% , 11.5% and 7.8% . Total 26.95% .
So deduct that from your Gross . $3468.73 - 26.95% leaves you with $ 2533.91.
That's your Realized Income . $2533.91 .
So you need to find 36% of that . It's $912.20.
And that is your answer . Your fixed expenses are $ 912.20 .
Answer:
$912.21
Step-by-step explanation:
Your primary jobs gross income = $3468.73
All deductions 7.65% (fica) + 11.5% (federal) + 7.8% (state tax) = 26.95%
Income after deductions = 3468.73 - ( 26.95% × 3468.73 )
= 3468.73 - (0.2695 × 3468.73)
= 3468.73 - 934.82
= $2,533.91
Fixed expenses on your realized income = 36%
Fixed expenses = 36% × 2,533.91
= 0.36 × 2,533.91
= $912.2076 ≈ $912.21
Fixed expenses are $912.21
Use a property of equality to solve this equation: 4.5x = 18 (never mind i figured out the answer.)
Answers

[tex] \frac{4.5x}{4.5} = \frac{18}{4.5} [/tex]
[tex]x= \frac{18}{4.5} [/tex]
[tex]x=4[/tex]
The solution to the equation 4.5x = 18 is x = 4.
We have,
To solve the equation 4.5x = 18, we can use the property of equality which states that if two quantities are equal, then multiplying or dividing both sides by the same non-zero number will still yield an equal equation.
In this case,
We want to isolate x, so we need to get rid of the coefficient 4.5.
To do this, we can divide both sides of the equation by 4.5:
(4.5x) / 4.5 = 18 / 4.5
Simplifying, we have:
x = 4
Therefore,
The solution to the equation 4.5x = 18 is x = 4.

IF the area of the frame was 64inches², what would be 2 possible sets of dimensions that could be used to make a frame with that area?

We know that the area of the frame is 64 inches^2. Let's list the factors of 64. They are:
1, 2, 4, 8, 16, 32, and 64.
There are many possible sets of dimensions.
The dimensions could be 1 in × 64 in, 2 in × 32 in, 4 in × 16 in, or 8 in × 8 in.
If the frame is shaped like a rectangle, then the first three sets of dimensions would be possible.
If it is a square, then the last (8 × 8) are possible.
Solve 5x + 1 = 2x2 + 9x. Which are steps in the process of completing the square used to solve the equation?
ANSWER CHOICES
1 = 2(x2 + 2x)
1 = 2x2 + 4x
2 = 2(x2 + 2x + 1)
3 = 2(x + 1)2
2 = 2(x + 1)2
Answers
Answer:
Choices (1), (2) and (4)
Step-by-step explanation:
5x + 1 = 2x² + 9x
By subtracting 5x form both the sides of the equation.
(5x + 1) - 5x = 2x² + 9x - 5x
1 = 2x² + 4x
1 = 2(x² + 2x)
By adding 2 on both the sides
1 + 2 = 2(x² + 2x) + 2
1 + 2 = 2(x² + 2x + 1)
3 = 2(x² + 2x + 1)
3 = 2(x + 1)²
Therefore, choices (1), (2) and (4) are the steps that have been used to complete the square.
To solve the equation 5x + 1 = 2x^2 + 9x using the method of completing the square, follow these steps: move all terms to one side of the equation, combine like terms, divide all terms by the coefficient of x^2, take half of the coefficient of x, square it, and add it to both sides of the equation, factor the left side of the equation, take the square root of both sides, and solve for x.
Explanation:To solve the equation 5x + 1 = 2x2 + 9x using the method of completing the square, the following steps are used:
Move all terms to one side of the equation: 2x2 + 9x - 5x - 1 = 0Combine like terms: 2x2 + 4x - 1 = 0Divide all terms by the coefficient of x2: x2 + 2x - 1/2 = 0Take half of the coefficient of x, square it, and add it to both sides of the equation: x2 + 2x + 1 = 1/4Factor the left side of the equation: (x + 1)2 = 1/4Take the square root of both sides: x + 1 = ±1/2Solve for x: x = -1 ± 1/2A garage contains a combination of 20 bikes and tricycles.

Answers
The solution explains how to find the number of bikes and tricycles in a garage based on the total number of wheels and the given combination.
Explanation:The question: A garage contains a combination of 20 bikes and tricycles. There are a total of 44 wheels.
Step-by-step solution:
Let's denote the number of bikes as B and the number of tricycles as T.
Each bike has 2 wheels, so the total number of wheels contributed by the bikes is 2B.
Each tricycle has 3 wheels, so the total number of wheels contributed by the tricycles is 3T.
Given that the total number of wheels is 44, we can form the equation: 2B + 3T = 44.
Since there are 20 bikes and tricycles in total, we have the equation: B + T = 20.
Solving the system of equations, we find that there are 12 bikes and 8 tricycles in the garage.

How to determine the probability?The given parameters are:
Sample size, n = 48Correct answers, x = 15Probability of right an answer, p = 0.25 i.e. 1 of 4 options is correctStart by calculating the mean
[tex]\bar x = np[/tex]
[tex]\bar x = 48 * 0.25[/tex]
[tex]\bar x = 12[/tex]
Calculate the standard deviation
[tex]\sigma = \sqrt{np(1 -p)}[/tex]
[tex]\sigma = \sqrt{12 * (1 -0.25)}[/tex]
[tex]\sigma = 3[/tex]
To get exactly 15,we make use of the range 14.5 to 15.5.
So, we calculate the z scores at these values using:
[tex]z = \frac{x - \bar x}{\sigma}[/tex]
This gives
[tex]z = \frac{14.5 - 12}{3} = 0.83[/tex]
[tex]z = \frac{15.5 - 12}{3} = 1.17[/tex]
The probability is then calculated using
P(14.5 < x < 15.5) = p(0.83 < z < 1.17)
This gives
P(14.5 < x < 15.5) = 0.082269
Approximate
P(14.5 < x < 15.5) = 0.0823
Hence, the probability that the student gets exactly 15 correct answers is 0.0823

-------------------------
At time 1.5s the height is 0 which is the resting position. The next time the height is 0 is when t = 4.5 which is a difference of 3 seconds (4.5 - 1.5 = 3). Double this to get 3*2 = 6
===============================================
Problem 2
Answer: 1.25
-------------------------
Notice how the period of this graph is 2.5 seconds. It takes 2.5 seconds for the up and down pattern to repeat fully again. The easiest way to see this is from x = 0 to x = 2.5 the down and then up pattern does one full cycle, only to repeat again from x = 2.5 to x = 5, and so on.
Half of this cycle is the length of time it takes for the particle to go from the peak to the valley, or vice versa. Half of 2.5 is 1.25 (2.5/2 = 1.25). Why is it half? Because a full cycle takes place from one valley to the next neighboring valley. The same happens with the peaks as well.
===============================================
Problem 3
Answer: 180 degrees
-------------------------
A full cycle takes 1.5 seconds, which consists of the wheel rotating 360 degrees (a full revolution)
Half a cycle is 1.5/2 = 0.75 seconds which is half a revolution 360/2 = 180 degrees

-------------------------
We plug in x = 2 since x = 0 corresponds to january, x = 1 corresponds to february, and so on
f(x) = 12.2*cos(pi*x/6) + 54.9
f(2) = 12.2*cos(pi*2/6) + 54.9
f(2) = 12.2*cos(3.14*2/6) + 54.9
f(2) = 12.2*cos(3.14/3) + 54.9
f(2) = 12.2*cos(1.04666666666667) + 54.9
f(2) = 12.2*0.5004596890082 + 54.9
f(2) = 6.10560820590003 + 54.9
f(2) = 61.0056082059
