Fisherman catches in fish their total mass is 15kg write down the average mass of fish in terms of n. if the average mass of a fish was 3/4 kg. Find the number of fish caught
Therefore , the solution of problem of average the number of
fish caught is 20.
How can we determine the average?Average The arithmetic mean is calculated by adding a set of numbers, dividing by their count, and then taking the result.
For instance, the result of 30 division by 6 is 5, which is the average of 2, 3, 3, 5, 7, and 10.
Here,
Given,
total mass of fish=15kg
average of fish=3/4kg
number of fish=?
Number of fish=total mass/average
number of fish=15/(3/4)=20
Therefore , the solution of problem of average the number of times is
fish caught is 20.

What is Simultaneous equation?Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations. This implies that the simultaneous equations have a common solution. Some of the examples of simultaneous equations are: 2x - 4y = 4, 5x + 8y = 3.
represent small box by x and large box by y
12x + 8y = 276 equation 1
6x + 9y = 228 equation 1
make the coefficients of x equal by multiplying equation 2 by 2
12x + 8y = 276 equation 3
12x + 18y = 456 equation 4
subtract equation 3 from 4
10y = 180
y = 180/10
y = 18
substitute 18 for y in equation 1
12x + 6×18 = 276
12x = 276-108
12x = 168
x = 168/12

How can I open my cervix naturally?
Natural methods that may help to open the cervix include acupuncture, herbs such as red raspberry leaf, exercise, sex and nipple stimulation.
There are several natural methods that may help to soften and open the cervix in preparation for childbirth, including:
Acupuncture: Acupuncture has been found to be effective in helping to prepare the cervix for labor by promoting the release of oxytocin, a hormone that can help to soften and open the cervix.
Herbs: Certain herbs, such as red raspberry leaf, can help to tone the uterus and prepare the cervix for labor.
Exercise: Regular physical activity can help to maintain good health and prepare the body for labor.
Sex: Semen contains prostaglandins which can help to soften the cervix.
Nipple stimulation: Stimulating the nipples can also cause the release of oxytocin, which can help to soften and open the cervix.
It is important to note that these methods may not work for everyone, and it is best to consult with a healthcare provider before trying any new method.
Also, It's not advisable to self-induce labor or try to open the cervix before it's time as it can cause problems for both mother and baby.

What is mean by polygon interior angle theorem? The Polygon Interior Angle Theorem states that the sum of all the interior angles of a polygon is equal to (n - 2)180 degrees, where n is the number of sides of the polygon. This theorem applies to all regular polygons, which are polygons with all sides of equal length. The theorem can be used to calculate the measure of an interior angle of a regular polygon by dividing the total sum of all the interior angles by the number of sides. For example, if a regular pentagon has five sides, the sum of the interior angles is 5(180) or 900 degrees. Therefore, the measure of each interior angle is 900/5 or 180 degrees. This theorem is also known as the Gauss-Bonnet theorem.
Solution:
Interior angle = (n-2) . 180°
(6 - 2) . 180°
Measure of Interior angle = 720°
x + 102 + 146 + 120 + 124 + 158 = 720°

what is sequence ?In mathematics, a sequence is a list of things that are in a particular order (or events). It has members, much like a set (also called elements, or terms). The number of ordered items determines the sequence's length (potentially infinite). Arithmetic sequences, geometric sequences, quadratic sequences, and special sequences are the four primary types of sequences that you should be aware with. A number sequence is a group of numbers connected by a rule. If you understand the rule, you can figure out the subsequent numbers in the series. Each number in this case differs from the others by 6. Because of this, the rule for this sequence is to add 6 each time.

The possible values of x, so that the relation does not form a function, is given as follows:

The points for the function in this problem are given as follows:
(-2,5),(-5,9),(x,-3)
The meaning of each point is that:
(-2,5): input of -2 is mapped to an output of 5.(-5,9): input of -5 is mapped to an output of 9.(x, -3): input of x is mapped to an output of -3.The relation is not a function, meaning that the value of x is either of x = -2 or x = -5, which are already mapped to another value of x.

A bathtub contains 6012
gallons of water. When the drain plug is pulled, the tub drains at an average rate of 4.5 gallons per minute. In how many minutes will the amount of water in the bathtub be 24.5 gallons?
Answer:
1326.78 minutes
Step-by-step explanation:
We know that the bathtub starts with 6012 gallons of water and that it drains at an average rate of 4.5 gallons per minute. To find how many minutes it will take to reach 24.5 gallons, we can use the formula:
time = (initial amount - final amount) / rate
Plugging in the given values, we get:
time = (6012 - 24.5) / 4.5
Solving for time:
time = 1326.78 minutes
It will take 1326.78 minutes for the bathtub to drain to 24.5 gallons of water.

What is the solution of 7x 9 16?
The solution of 7x -9 = 16 is x = 25/7. It is called a linear equation as it contains a highest degree of 1.
The general form of a linear equation is ax + by + c = 0, where a, b, c are real numbers and at least one of a or b is not zero.
In the given equation above, 7x - 9 - 16 = 0.
7x - 25 = 0
Here, a = 7, b = 0, c = -25
To find the solution of this equation, we must make x as subject.
7x - 25 = 0
7x = 25
x = 25/7
Thus, the required solution of the given equation is calculated to be 25/7.

What is an example of a two-step inequality?
A two-step inequality is an inequality that requires more than one step to solve. An example of a two-step inequality is to solve the inequality 2x - 3 ≥ 5.
Example: Solve the inequality 2x - 3 ≥ 5
Step 1: Isolate the variable by adding 3 to both sides: 2x ≥ 8
Step 2: Divide both sides by 2: x ≥ 4
In this example, the first step is to isolate the variable x by adding 3 to both sides of the inequality. In the second step, we divide both sides by 2 to get the final solution of x ≥ 4.
It's worth noting that this inequality has a solution that is an interval, it is x ≥ 4, which means that all values of x that are greater or equal to 4 are solutions of the inequality.
It's important to keep in mind that inequalities may require multiple steps to solve and may not always have a single solution. It's important to check the solution by substituting back into the inequality to make sure it holds true.

A train left Vicky' town and traveled for 4 hour and 50 minute to Wildgrove. Then it traveled 2 hour and arrived in Wetminter at 12:28 P. M. What time did the train leave Vicky' town?
The train left Vicky's town at 7:38 A.M. after traveling for 4 hours and 50 minutes to Wildgrove.
To calculate this, we need to work backward from the arrival time in Westminster. The train arrived in Wetminter at 12:28 P.M. and it took 2 hours to travel from Wildgrove to Westminster. So, if we subtract 2 hours from 12:28 P.M., we get 10:28 A.M.
Next, we need to take into account the time it took for the train to travel from Vicky's town to Wildgrove. The train traveled for 4 hours and 50 minutes to Wildgrove.
So, if we convert 4 hours and 50 minutes to minutes (4*60+50 = 290 minutes) and subtract it from 10:28 A.M., we get 7:38 A.M. This is the time the train left Vicky's town.
