Dale will receive $1200, Evelyn will receive $1800, and Frank will receive $1500 of the $4500 profit.
What is profit ?
Profit is a financial term that refers to the difference between the revenue earned by a business or individual and the expenses incurred in producing or delivering goods or services. In other words, profit is the amount of money that is left over after all the costs of doing business have been paid.
Profit is an important indicator of the financial health of a business or individual, as it measures how much money is being earned from a particular activity or investment. A positive profit indicates that revenues are higher than expenses, while a negative profit indicates that expenses are higher than revenues.
According to the question:
The total investment is $4000 + $6000 + $5000 = $15000.
The proportion of the profit that each person will receive is equal to their investment divided by the total investment:
Dale's proportion = $4000 / $15000 = 4/15
Evelyn's proportion = $6000 / $15000 = 2/5
Frank's proportion = $5000 / $15000 = 1/3
To find each person's share of the profit, we multiply the total profit by their proportion:
Dale's share = (4/15) x $4500 = $1200
Evelyn's share = (2/5) x $4500 = $1800
Frank's share = (1/3) x $4500 = $1500
Therefore, Dale will receive $1200, Evelyn will receive $1800, and Frank will receive $1500 of the $4500 profit.

A shop is having a 40% sale. A jumper originally costs £50. How much will it be in sale?
Answer:
30 pounds
Step-by-step explanation:
Since the jumper costs 50 pounds, the decimal for the number will be:
50.
To find ten percent of the number, you move the decimal one time to the LEFT.
Therefore, 10% of 50 pounds will be 5 pounds. To find 40%, we simply will multiply the 10% amount by 4.
40% of 50 will be:
20
Therefore, the jumper will have 20 pounds off.
Since the original cost is 50 pounds, we simply will just subtract 50 - 20:
50 - 20 = 30
The jumper will cost 30 pounds with the sale deal.

fill in the blank. Find the kinetic energy of the following particles that each have a de Broglie wavelength of 0.50 nm.? (a) photons ____eV = 2480eV
The kinetic energy of particle with a de Broglie wavelength of 0.50 nm is 82.6 eV.
The given de Broglie wavelength of 0.50 nm corresponds to photons. The formula for the kinetic energy of a particle with a given de Broglie wavelength λ is given by:
K = (hc/λ) - mc^2
where h is Planck's constant, c is the speed of light, and m is the rest mass of the particle.
For photons, the rest mass is zero, so the formula simplifies to:
K = hc/λ
Plugging in the given wavelength of 0.50 nm, we get:
K = (6.626 × 10^-34 J s × 3.00 × 10^8 m/s) / (0.50 × 10^-9 m)
K = 1.3252 × 10^-17 J
Converting to electronvolts (eV), we use the conversion factor 1 eV = 1.602 × 10^-19 J:
K = (1.3252 × 10^-17 J) / (1.602 × 10^-19 J/eV)
K = 82.6 eV (rounded to three significant figures)
Therefore, the kinetic energy of photons with a de Broglie wavelength of 0.50 nm is 82.6 eV (rounded to three significant figures).

Amelia uses 99 balls of yarn in all to make the sweaters and scarves.
What is addition ?
Addition is a basic mathematical operation that combines two or more quantities to find a total or a sum. It is denoted by the symbol "+" and is usually taught in elementary school. In addition, the order of the numbers does not matter, meaning that you can add them in any order and still get the same result. For example, 3 + 5 is the same as 5 + 3, and the answer is 8 in both cases.
According to the question:
To find the total number of balls of yarn that Amelia uses, we can start by finding the total number of balls of yarn she uses to make the sweaters and scarves separately, and then add those amounts together.
To make 7 sweaters, Amelia uses 7 x 9 = 63 balls of yarn.
To make 9 scarves, Amelia uses 9 x 4 = 36 balls of yarn.

What is the degree measure of the smaller angle between the hour and minute hands of the clock at 5:10 PM?
F. 110°
G. 105°
H. 100°
J. 95°
K. 90°
Answer:
At 5:10 PM, the minute hand is at the 2-minute mark, and the hour hand is between the 5 and 6 marks, closer to the 5.
The minute hand is at the 2-minute mark, which is 1/30th of the way around the clock face. So, the minute hand has traveled 1/30th of a full circle, which is 360°, or 12°.
The hour hand is between the 5 and 6 marks, closer to the 5. It has passed the 5 and is 1/6th of the way to the 6. Since the clock face is divided into 12 hours, 1/6th of the way from 5 to 6 is 5 + 1/6 = 5.166... hours.
Each hour mark represents 30 degrees, so the hour hand has traveled 5.166... × 30 = 155 degrees from the 12 o'clock position.
The smaller angle between the hands is the angle between the hour hand and the minute hand that is less than 180 degrees. We can find this angle by subtracting the smaller angle between the hands from 360 degrees.
To find the smaller angle between the hands, we can subtract the angle traveled by the hour hand from the angle traveled by the minute hand:
12° - 155° = -143°
The negative sign indicates that the angle is measured clockwise from the 12 o'clock position. To find the positive angle between the hands, we add 360 degrees:
360° - 143° = 217°
Therefore, the degree measure of the smaller angle between the hour and minute hands of the clock at 5:10 PM is approximately 217 degrees. Since this value is not one of the answer choices, we can round it to the nearest choice, which is F. 110°

Case 1
|(x - 19) + 11| = |x - 8|
|x - 8| = x - 8 for x > 8
|x - 8| = 0 for x = 8
|x - 8| = 8 - x for x < 8
Case 2

Show that,the sum of an infinite arithmetic progressive sequence with a positive common difference is +∞.
The sum of the arithmetic progressive sequence will be +∞, for common difference as positive that is d >0.
Explain about the arithmetic progression?The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP).
A good example of an arithmetic progression (AP) is the series 2, 6, 10, 14,..., which follows a pattern in which each number is created by increasing 4 to the previous term. This annual income of a worker whose pay rises by a predetermined amount of $5000 each year serves as a real-world illustration of an AP.
The expression for an arithmetic progression:
a is the first term
l is last term
d is common difference
n is total number of terms
Sn = the sum of term
A.P = a,a+d,a+2d,a+3d,…, a+(n-1)d
l = a+(n-1)d
Sum formula:
Sn=n/2 [a+(n-1)d]
Or, Sn=n/2 [a+l]

Milly took a loan of N$900 with simple interest for as many years as the rate of interest. If she paid N$324 as
interest at the end of the loan period, what was the rate of interest?
Answer:
Let's assume that the rate of interest is r (in decimals), and the time period is also r years. Then we can use the simple interest formula:
I = P * r * t
where I is the interest paid, P is the principal amount (the loan amount in this case), r is the rate of interest per year, and t is the time period in years.
Substituting the given values, we get:
324 = 900 * r * r
Simplifying, we get:
r² = 324/900
r² = 0.36
Taking the square root of both sides, we get:
r = ±0.6
Since the rate of interest cannot be negative, we can take r = 0.6. Therefore, the rate of interest is 0.6 or 60% per year.

Step-by-step explanation:
you have a total of 60mg, it is asked how much hours it takes to remove half the caffeine which is 30mg
1 hour removes 15%, 15% of 60 is 9g
(15/100×60) = 9
now it removes only 9g in an hour, we have to find out how long (hours) it'll take to remove 30g
30÷9= 3.33 hours
A box containing 5 balls costs $8.50. If the balls are bought individually, they cost $2.00 each. How much cheaper is it, in percentage terms, to buy the box as opposed to buying 5 individual balls?
Answer: The total cost of buying 5 balls individually is $2.00 x 5 = $10.00.
The box costs $8.50, which means it is $10.00 - $8.50 = $1.50 cheaper to buy the box.
To calculate the percentage difference, we can use the formula:
% difference = (difference ÷ original value) x 100%
In this case, the difference is $1.50, and the original value is $10.00.
% difference = ($1.50 ÷ $10.00) x 100%
% difference = 0.15 x 100%
% difference = 15%
Therefore, it is 15% cheaper to buy the box than to buy 5 individual balls.

The equation of the line passing through A and B is y = (4/5)x - (2/5).
What is the line example's equation?A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis. The y-axis intercept is denoted by the number c. A straight line with gradient m and intercept c on the y-axis has the equation y = mx + c.
The point-slope form of a linear equation can be used to find the equation of the line passing through points A and B:
y - y1 = m(x - x1) (x - x1)
where m denotes the slope of the line, (x1, y1) denotes the coordinates of point A or B, and (x, y) denotes the coordinates of any other point on the line.
To calculate the slope, we can use points A (3, 2) and B (8, 6).
m = (y2 - y1) / (x2 - x1) = (6 - 2) / (8 - 3)\s= 4 / 5
So the equation for the line connecting A and B is:
y - 2 = (4/5)(x - 3) (x - 3)
This equation can be simplified by multiplying both sides by 5:
5y - 10 = 4x - 12
Then we can rearrange it to form the slope-intercept equation, y = mx + b:
5y = 4x - 2
y = (4/5)x - (2/5)
As a result, the equation for the line connecting A and B is y = (4/5)x - (2/5).
