What is Proportion ?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal. Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
Volume= 16
Width = 4
So, we can write the relation as
Volume= k (width)
k = Volume/ width
k= 16/4
k = 4
Hence, the value of k is 4.

Willy is an avid fisherman of the world. As he travels, he goes fishing 2 times on every mainland Country he visits and goes fishing 5 times on every Island he visits.
As far as he remembers, Willy went fishing 65 times in the total of the 25 unique Countries and Islands he visited.
How many Countries and Islands did Willy visit? (Where and represent the countries and islands)
The number of mainland countries is 20 and the number of island countries is 5 countries that Willy visited.
How to calculate the value?Let the number of mainland be represented by m
Let the number of island be represented by x.
This will be illustrated as:.
m + x = 25 .... i
2m + 5x = 65 .... ii
From equation i, m = 25 - x.
Put this into equation ii
2m + 5x = 65
2(25 - x) + 5x = 65
50 - 2x + 5x = 65
3x = 65 - 50
3x = 15
Divide
x = 15 / 3
x = 5
Island countries = 5
Since m + x = 25
m = 25 - 5 = 20
Mainland countries = 20

A new student, who has had very little experience solving equations algebraically, has just joined your study group. Show and explain all of the steps necessary to solve the equation 2(x + 1) = 6(x – 1) for x. Be sure to include a step for checking the solution.
The solution of the equation 2(x + 1) = 6(x – 1), is the value of x = 2.
How to Solve an Equation?To solve an equation means to find what the value of the variable of the equation would be that would make the equation true if the value of the variable is plugged into the equation.
The necessary steps taken to find the value of x in the equation, 2(x + 1) = 6(x – 1) are explained below:
2(x + 1) = 6(x – 1) [given]
Apply the distributive property
2x + 2 = 6x - 6
Combine like terms
2x - 6x = -2 - 6
-4x = -8
Divide both sides by -4
-4x/-4 = -8/-4
x = 2
The value of x is 2. To check the solution, plug in the value of x back into the equation:
2(2 + 1) = 6(2 – 1)

Let's multiply the top equation by -2. What would be our new equation?
2x + 3y = 12
4x - 7y = -54
New equation will be 4x + 6y = 24, if we multiply the equation 2x + 3y = 12 by -2.
Define multiplication.We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group. A fact involving multiplication is the result of two distinct integers. Additionally, the product is unaffected by the arrangement of the numbers. For instance, 32=6 and 23=6. The distributive, commutative, associative, removes a common factor, and neutral element characteristics of multiplication.
Given,
Equations:
2x + 3y = 12
4x - 7y = -54
Multiplying the top equation by -2:
-2(2x + 3y) = -2(12)
-2(2x) -2(3y) = -24
Product:
-4x - 6y = -24
Taking - common,
-(4x + 6y) = -24
4x + 6y = 24

Note one gallon of water equals 231 cubic inches. If Anna is going to clean the fish tank which measures 48 inches long by 11 inches wide by 35 inches high, how many gallons of water will it take to fill the fish tank?
If any one sees this question please help me answer it because I am having a lot of trouble.
It will take 80 gallons of water to fill the fish tank.
What is volume?The amount of space occupied by a three-dimensional object or region of space.
Given that, Anna is going to clean the fish tank, which measures 48 inches long by 11 inches wide by 35 inches high
The fish tank is cuboidal,
Volume of cuboid = length*width*height
Therefore, volume of fish tank = 48*11*35 = 18,480 in³
1 gallon = 231 in³
So, 18,480 in³ = 18,480/231 gallons = 80 gallons
Hence, Volume of tank = 80 gallons

Time taken by an earthworm to accelerate from a speed of 0.01 m/s to 0.02 m/s over a distance of 0.9 m is 59.88 s
What is acceleration?
At first, it is important to know about velocity
Distance travelled by a body per unit interval of time in a particular direction is called Velocity
The rate of change of velocity is called acceleration.
Acceleration is a vector quantity as the direction is taken into account.
Initial velocity of earthworm (u)= 0.01 m/s
Final velocity of earthworm (v) = 0.02 m/s
Distance (s) = 0.9 m
We know,
[tex]v^2 = u^2 + 2as\\0.02^2 = 0.01^2 + 2 \times a \times 0.9\\0.02^2 - 0.01^2 = 1.8a\\(0.02 + 0.01)(0.02 - 0.01) = 1.8a\\a = \frac{0.03 \times 0.01}{1.8}\\a = 0.000167 \ ms^{-2}[/tex]
