$37,500 profit
To solve this, find the unit rate by dividing 2500 by 20. This will get you an average of $125 profit made per product sold. Then multiply that by 300 (the number of products sold in total) to get your answer of $37,500 profit total.
Answer:
Assuming that the profit is the same for each sale, the amount they make is 37,500
Step-by-step explanation:
In order to find this, we set up a proportion using those numbers.
2500/20 = x/300 ----> Cross multiply
20*x = 2500*300 ----> Multiply
20x = 750,000 ----> Divide by 20
x = 37,500

why are diagrams that show how matter moves through organisms and the environment called cycles
"The correct answer is that diagrams showing how matter moves through organisms and the environment are called cycles because they depict continuous, circular pathways.
In ecosystems, matter is not created or destroyed but is continuously recycled. This recycling process occurs in a loop or cycle, where matter moves from the environment to organisms and then back to the environment. For example, in the carbon cycle, carbon dioxide is taken in by plants during photosynthesis, then passed on to animals that consume the plants, and eventually returned to the environment through processes like respiration and decomposition.
These cycles are essential for the sustainability of ecosystems because they ensure that nutrients and other materials are reused and not depleted. The term ""cycle"" reflects the repeating and ongoing nature of these processes, highlighting the interconnectedness and interdependence of organisms and their environment. By using diagrams to represent these cycles, we can visualize and better understand the complex interactions and pathways that matter follows in ecosystems."

Jane is X years old today. her brother Kenny is four years older l. after seven years of their total combined age will be 24 years. Write a linear equation for their total combination age after seven years
Answer:
The linear equation for the total combination age is [tex]X+7+(X+4)+7=24[/tex]
Step-by-step explanation:
If Jane is X years old today. And her brother is 4 years older then her brothers age is,
X+4.
Jane's age after 7 years = X+7
Jane's Brothers age after 7 years = (X+4)+7
So after seven years their combined age will be 24, Lets write this in an equation form,
[tex]X+7+(X+4)+7=24[/tex]
So the linear equation for the total combination age is,
[tex]X+7+(X+4)+7=24[/tex]

A boy jogs 250 meters in 110 seconds. What is his average speed in m/s?
Answer:
2.72 m/s
Step-by-step explanation:
We are given that
Boy jogs=250 meters
Time taken by boy=110 seconds
We have to find the average speed in m/s
In order to find the average speed then we will divide distance by time
[tex]Average\;Speed=\frac{distance}{time}[/tex]
Using the formula then we get
Average speed=[tex]\frac{250}{110}=2.72 m/s[/tex]
Hence, the average speed=2.72 m/s
Final answer:
To calculate the average speed, the boy's distance jogged (250 meters) is divided by the time taken (110 seconds), yielding an average speed of 2.27 m/s.
Explanation:
The student's question asks how to calculate the average speed of a boy who jogs a certain distance in a given amount of time. To find the average speed, you divide the total distance traveled by the total time taken. In this case, the boy jogs 250 meters in 110 seconds.
The calculation for the average speed (v) would be:
Distance (d) = 250 meters
Time (t) = 110 seconds
Average Speed (v) = d / t
Plugging the values into the equation yields:
Average Speed (v) = 250 m / 110 s = 2.27 m/s
Hence, the boy's average speed is 2.27 meters per second.

Henry deposited $420 into a savings account. There is a $5.00 per month service fee on the account. Also, Henry decides he wants to withdraw $25 a week for spending money. In how many months will Henry run out of money? A) 3 months Eliminate B) 4 months C) 5 months D) 6 months
Answer:
Step-by-step explanation:
Given that Henry deposited $420 into a savings account. There is a $5.00 per month service fee on the account. Also, Henry decides he wants to withdraw $25 a week for spending money.
Let us convert everything into days.
30 days a month and 7 days in a week
Service charges for 30 days = 5
withdrawn amount for 7 days = 25
Let x be the total no of days
Then [tex]\frac{25x}{7} +\frac{5x}{30}= 420\\\\750x+35x=420(7)(30)\\785x=420(7)(30)\\x=112.3567[/tex]
i.e. between 3 and 4 months

x = 4, y = -3x = 1, y = -2.5Please find attached the graph showing the feasible region, which is the solution of the system of inequalities, created with MS ExcelPlease find attached the graph showing the solution of the system of inequalitiesHow can the solution of a system of equations be found graphically?In order to find the solution of the system of equations by graphing, the lines are graphed on the same coordinate plane and the point at which the two graphs intersect is the solution of the system of equations.
1) y = (1/4)·x - 4, y = (-1/2)·x - 1,
The x-coordinates at the point of intersection, can be found by noting that the y-values of both equations are the same
Please find attached the graph of the system of equations with the point of intersection, (4, -3), which corresponds to x = 4, and y = -3, created with MS Excel
The solution of the system of equations therefore is; x = 4, y = -3
2. 3·x - 2·y = 8
x - 2·y = 4
Making y the subject of both equations, we get;
y = (3/2)·x - 4
y = (1/2)·x - 2
The graph of the above two equations can be plotted on the same coordinate plane using MS Excel, is attached
The point of intersection of the two graphs is (1, -2.5)
The solution of the system of equations is therefore; x = 1, and y = -2.5
3) The solution of the system of inequalities is the feasible region, corresponding to the region that satisfies both inequalities;
Please find attached the graph of the inequalities, showing the positive region that satisfies both inequalities, which is the triangle with vertices, (0.51, 0), (1, 1), and (1.5, 0)
4) The inequalities can be graphed by making y the subject of both inequalities and graphing the equations on the same coordinate plane.
x + y > -2, therefore; y > -2 - x
6·x - y ≥ 3, therefore; y ≤ 6·x - 3
6·x - 3 = -2 - x
The points in the feasible region of the graph are; points below and on the line, y = 6·x - 3, above the line y = -2 - x, and to the right of the point (1/7, -2 1/7)

A road crew is widening a street that is 24 m wide. Their scale drawing says the new street has to be 125% of the width of the old street. How wide should the new street be? A. 19.2 m B. 28 m C. 30 m D. 300 m
If the street is already 24 m wide, and it is being expanded by 125%, then the correct answer is C. 30 m!
125% simply means 1 1/4. 1/4 of 24 is 6. So, you have 24 + 6 = 30!
Answer:
The correct answer is C: the new street should be 30m wide.
Step-by-step explanation:
This is a simple problem of per-cents. Perhaps the easiest way to do it is to use a basic ‘‘rule of three’’. In this particular case the 100% is the width of the old street, i.e. 24 m; and we want to know the new width, that is 125% of the old street. So,
24 ---- 100%
x ----- 125%
To find x we use the formula
[tex]x = \frac{24*125}{100} = 3000/100=30[/tex]
So, the width of the new street is 30m.

at 1:30 in the afternoon an old freight train and a new dart express train pull out of the new garland station going in opposite directions the dart express train goes three times faster than the hold freight train. fifteen minutes later the two trains are already 30 miles apart find the speed of each train?
Answer:
[tex]V_{E} = -22.5 / 15 = 1.5 miles/minute\\V_{F} = 7.5 / 15 = 0.5 miles/minute[/tex]
Step-by-step explanation:
To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.
If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.
So
[tex]F + E = 30\\[/tex]
We also know that:
[tex]E = 3F[/tex]
Since the express train travels 3 times faster than the freight train.
So, like both equations, we have to:
[tex]F + 3F = 30\\F = 30/4\\F = 7.5 miles\\[/tex]
Then [tex]E = 7.5*3 = 22.5[/tex] miles in the opposite direction.
This is the distance you traveled in 15 minutes.
Therefore, the speed of the express train ([tex]V_{E}[/tex]) is the distance traveled between the time it did
[tex]V_{E} = -22.5 / 15 = 1.5 miles/minute\\V_{F} = 7.5 / 15 = 0.5 miles/minute[/tex]
The second of three numbers is 6 more than the first. The third number is twice the first. The sum of the three number is 26. Find the three numbers
Let's have the first number be x, the second number y, and the third number z.
Because the second number is six more than the first, y = x + 6.
Because the third number is twice the first, z = 2x.
The three numbers added together equals 26, so 26 = x + y + z.
Let's substitute y = x + 6 and z = 2x into 26 = x + y + z. This gives us:
26 = x + x + 6 + 2x
26 = 4x + 6
We subtract 6 from both sides of the equation and divide by 4 to get:
5 = x
Now, we'll put x = 5 into our previous to equations to find y and z:
y = 5 + 6
y = 11
z = 2*5
z = 10
Let's check out answer. 10 + 11 + 5 = 26. 10 is twice of 5 and 11 is 6 more than 5. Thus our three numbers are 10, 11, and 5.
The three numbers are 5, 11 (5 + 6), and 10 (2 * 5)
Explanation:Let's call the first number x
The second number is 6 more than the first, so it is x + 6
The third number is twice the first, so it is 2x
The sum of the three numbers is 26, so we have the equation x + (x + 6) + 2x = 26
Combining like terms, we get 4x + 6 = 26
Subtracting 6 from both sides, we get 4x = 20
Dividing both sides by 4, we get x = 5
So the three numbers are 5, 11 (5 + 6), and 10 (2 * 5)
