how to calculate Bi weekly pay?
Calculating bi-weekly pay involves determining the total earnings for a two-week period. Here's the process 1. Determine the hourly rate: Start by determining the hourly rate of pay. For example, let's say the hourly rate is $15.
2. Calculate regular earnings: Determine the number of hours worked in a two-week period. Let's assume 80 hours. Multiply the hourly rate by the number of hours worked to calculate the regular earnings: $15/hour x 80 hours = $1200.
3. Calculate overtime (if applicable): If there are any overtime hours, calculate the overtime earnings separately. Typically, overtime is paid at a higher rate (e.g., 1.5 times the regular hourly rate) for hours worked beyond a certain threshold (e.g., 40 hours per week). Multiply the overtime hours by the overtime rate and add this amount to the regular earnings.
4. Deduct taxes and other withholdings: Subtract the applicable taxes and other withholdings from the total earnings. This may include federal income tax, state income tax, Social Security tax, Medicare tax, and any other deductions.
5. Determine the net pay: Subtract the deductions from the total earnings to calculate the net pay—the amount the employee takes home after taxes and withholdings.
It's important to note that bi-weekly pay may also include additional components such as bonuses, commissions, or other allowances. These should be factored into the calculations accordingly.
By following these steps, you can calculate an employee's bi-weekly pay based on their hourly rate, hours worked, and any additional components or deductions involved.

raj bought 300 mangoes at per 10 mangoes for RS 100 and sold them at a profit of 25% at what rate he sell per 15 mangoes
Raj would sell 15 mangoes at a rate of Rs 187.50 in order to achieve a profit of 25%.
To find the selling rate per 15 mangoes, we need to consider the buying price, profit percentage, and the number of mangoes.
Given:
Number of mangoes bought = 300
Buying price for 10 mangoes = Rs 100
Profit percentage = 25%
Calculate the cost price of 1 mango.
Cost price per mango = Buying price for 10 mangoes / 10
Cost price per mango = Rs 100 / 10
Cost price per mango = Rs 10
Calculate the selling price of 1 mango, including the profit.
Profit per mango = Cost price per mango * Profit percentage
Profit per mango = Rs 10 * 25/100
Profit per mango = Rs 2.50
Selling price per mango = Cost price per mango + Profit per mango
Selling price per mango = Rs 10 + Rs 2.50
Selling price per mango = Rs 12.50
Calculate the selling price for 15 mangoes.
Selling price per 15 mangoes = Selling price per mango * 15
Selling price per 15 mangoes = Rs 12.50 * 15
Selling price per 15 mangoes = Rs 187.50
Therefore, Raj would sell 15 mangoes at a rate of Rs 187.50 in order to achieve a profit of 25%.

ABCD is a kite, if RA=20yds and BD=44yds find AB
Answer:
Step-by-step explanation:
In a kite, the diagonals intersect at right angles, and the longer diagonal is the perpendicular bisector of the shorter diagonal. In this case, we have BD as the longer diagonal and RA as the shorter diagonal.
Given that BD is 44 yards and RA is 20 yards, we can determine the length of AB by using the properties of a kite.
The length of AB can be found by applying the Pythagorean theorem to the right triangle formed by AB, BD, and the segment of the longer diagonal perpendicular to the shorter diagonal.
Using the Pythagorean theorem, we have:
AB^2 = BD^2 - RA^2
AB^2 = 44^2 - 20^2
AB^2 = 1936 - 400
AB^2 = 1536
Taking the square root of both sides:
AB = √1536
Simplifying the square root:
AB ≈ 39.19
Therefore, AB is approximately 39.19 yards.

5.3 Suppose the radius of a second solid metal ball, B₂, is half the radius of ball B₁. Suppose ball B₂ was put into the tank of water instead of ball B₁. Would the surface of the water be 4cm below the top of the tank? Explain your answer. (5)
If ball B₂ is placed in the tank instead of B₁, the surface of the water would not be 4cm below the top of the tank. It would be lower than that, indicating that ball B₂ causes a lesser rise in the water level due to its smaller volume.
No, the surface of the water would not be 4cm below the top of the tank if ball B₂ with a radius half of B₁ was placed in the tank instead.
The water level in a tank is determined by the volume of the object submerged in it, not just the radius of the object. The volume of a sphere is directly proportional to the cube of its radius.
Let's assume the radius of ball B₁ is r. Then, the radius of ball B₂ would be (1/2) * r.
The volume of ball B₁ can be calculated as V₁ = (4/3) * π * r³.
Similarly, the volume of ball B₂ can be calculated as V₂ = (4/3) * π * (1/2 * r)³ = (1/6) * (4/3) * π * r³.
The volume of water displaced by ball B₁ would be equal to V₁, which would cause the water level to rise.
However, the volume of water displaced by ball B₂ would be equal to V₂, which is only (1/6) of V₁. This means that ball B₂ would displace less water compared to B₁, resulting in a lower rise in the water level.
Therefore, if ball B₂ is placed in the tank instead of B₁, the surface of the water would not be 4cm below the top of the tank. It would be lower than that, indicating that ball B₂ causes a lesser rise in the water level due to its smaller volume.

2. Why did she accuse me?
3. Why did Nyla look at me after being accused but didn't laugh
4. Why did Ms. Nee (the teacher) tell me to move after I was accused
1) It's possible that Lia had a mean smirk because she found the situation amusing or thought it was funny to accuse someone.
2) Lia might have accused you based on the assumption that you were laughing
3) Nyla might have looked at you out of curiosity or suspicion, wanting to see your reaction to the accusation.
4) Ms. Nee might have asked you to move in an attempt to diffuse the situation or prevent any further disruptions.
How do we analyze the situation?Lia could have been amused by the event or thought it was hilarious to blame someone, hence her cruel smirk. Another possibility is that she made the charge because she was upset with you personally and wanted to humiliate or degrade you.
Lia could have charged you if she thought you were laughing, which she took to be an admission of guilt. Additionally, she might have been looking for someone to point the finger at and chose you as the victim of choice without any solid proof.
Nyla may have glanced your way to see how you would respond to the charge out of curiosity or suspicion. Her lack of laughter could indicate that she wasn't sure about your involvement or that she simply didn't find the situation amusing.
Everyone present may find it distracting and uncomfortable when jokes and accusations are made in the classroom. Ms. Nee might have asked you to relocate in an effort to bring back some sense of calm and concentration in the classroom.

The paint needed for a 980 ft2 room costs $35.25 per gallon. What is the total cost of the paint
needed to paint the room?
Note: Assume that one gallon of paint will cover a total of 350 square feet.
O $88.60
O $98.70
O $88.12
O $89.07
Answer:
$98.70
Step-by-step explanation:
Number of gallons = Area of room / Coverage per gallon
Number of gallons = 980 ft^2 / 350 ft^2/gallon
Number of gallons = 2.8 gallons
Therefore, we need 2.8 gallons of paint to cover the room. The cost of one gallon of paint is given as $35.25, so the total cost of the paint needed to paint the room is:
Total cost = Number of gallons × Cost per gallon
Total cost = 2.8 gallons × $35.25/gallon
Total cost = $98.70
So, the total cost of the paint needed to paint the room is $98.70.

The measure of side length EF in the right triangle is 24.
What is the measure of side length EF?The Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
It is expressed as;
c² = a² + b²
From the diagram:
Hypotenuse DE = c = 26
Leg DF = a = 10
Leg EF = b = ?
Plug in the values and solve for b:
c² = a² + b²
26² = 10² + b²
676 = 100 + b²
b² = 676 - 100
b² = 576
b = +√576 ( we take the positive value since we are dealing with dimensions)
b = 24
Therefore, the length EF is 24.

What graph represents the piecewise-defined function ? y={6 if x <-3, 3 if -32
The graph of the piecewise-defined function will consist of two horizontal line segments.
The piecewise-defined function can be represented using a graph with two separate segments.
First, let's consider the segment where the value of y is 6 when x is less than -3. This means that for any x-value less than -3, the corresponding y-value is 6. This segment will be a horizontal line parallel to the x-axis, located at the y-coordinate of 6.
Next, let's consider the segment where the value of y is 3 when x is greater than or equal to -3 and less than or equal to 2. This means that for any x-value between -3 and 2 (inclusive), the corresponding y-value is 3. This segment will also be a horizontal line parallel to the x-axis, located at the y-coordinate of 3.
To summarize:
For x < -3, y = 6.
For -3 ≤ x ≤ 2, y = 3.
Therefore, Two horizontal line segments make up the graph of the piecewise-defined function. One segment will be located at y = 6, and the other segment will be located at y = 3. The vertical range of the graph will extend to include both y-values (6 and 3), while the horizontal range will depend on the given x-values and the interval specified.

What is 52% of 78? Round to one decimal place.
Answer:
40.6
Step-by-step explanation:
Step 1: Convert 52% to a decimal:
We can find 52% of 78 by multiplying the decimal form of the percentage by 78.To convert a percentage to a decimal, imagine the percentage sign as a decimal place with two 0s after the decimal. Thus, imagine 52% as 52.00.Then, you move the decimal two places to the left (this is the same as dividing by 100 since a percentage is always out of 100):Thus, 52% as a decimal is 0.52.
Step 2: Multiply 0.52 by 78 and round to one decimal place:
Now we can multiply 0.52 by 78 and round to one decimal place to find 52% of 78:
0.52 * 78
40.56
40.6
Thus, 52% of 78 is about 40.6,
