What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is a fictional shrinking man shrinks proportionately to 1/10 his original height.
Assume the weight to be [W]. Then -
W = mg
m = ρV {ρ is density}
Then -
W = ρVg
Assume the body to be cylinder of radius [r] and height [h], we can write-
W = πr²ρgh
Than, the initial weight will be -
W = πr²ρgh
After Shrinking -
W' = πr²ρgh/10
Then -
W'/W = {πr²ρgh/10}/{πr²ρgh}
W'/W = πr²ρgh/10 x 1/πr²ρgh
W'/W = 1/10
W' = W/10
Therefore, the final weight will be reduced by 1/10 of its original weight.

A bicycle store costs $1700 per month to operate. The store pays an average of $75 per month. The average selling price of each bicycle is $95. How many bicycles must the store sell each month to break even?
The formula in computing the break-even point is:
Break-even = fixed cost / contribution margin
The fixed cost is already given which is $1700 per month. To compute for the contribution margin, you have to deduct the average cost per month ($75) to the selling price of each bicycle ($95). The contribution margin is $20 ($95 - $75).
Substituting the amounts to the formula:
Break-even = $1,700/$20
= 85
Therefore, the store must sell 85 bicycles each month to break even.

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
we have,
A room's length is 3 feet less than twice its width.
The area of the room is 135 square feet.
let the width be x then length = 2x - 3.
So, Area of Room
135 = l w
135 = x (2x- 3)
2x² - 3x - 135= 0
2x² + 15x - 18x - 135 = 0
x (2x+ 15) - 9 (2x- 15)= 0
(2x+ 15)(x- 9)=0
x= -15/2 or x= 9.
Thus, the dimensions of room are:
Length = 2(9)-3 = 15 feet
Width = 9 feet

Sonya has four straws of different lengths: 2cm,8cm,14cm,and 16cm. How many triangles can she make using the straws?
There is no way to make a triangle with numbers 2,8,14, nor 2,8,16, nor 2,14, and 16. Using 6, 14, and 16 straws, you can form a triangle.
I'm guessing you're not supposed to stick any one of the straws together. Kindly see the accompanying document for more information. As a result, B is represented by one triangle. All two sides add up to more than the third side. As a result, the difference between the two sides is less than the difference between the first and third sides.Therefore, the final answer is "one triangle".

Company A can produce 100 CPUs in 3 days while Company B can produce 150 CPUs in 4 days. If the two companies join forces, how many days would it take them to produce 1000 CPUs?
Answer: They would need 15 days
Step-by-step explanation:
The data is:
Company A produce 100 CPUs in 3 days, so the rate per day is:
Ra = 100/3 CPUs per day: 33.33 CPUs per day.
Company B produce 150 CPUs in 4 days, then it produces:
Rb = 150/4 = 37.5 CPUs per day.
Then, if both companies work toggeter, they produce
Ra + Rb = 33.33 + 37.5 CPUs per day = 70.83 CPUs per day.
We want to know the number X of days needed to make 1000 CPUs, then we need to solve:
70.83*X = 1000
X = 1000/70.83 = 14.11 days, we could round it up to 15 days if we want to have a whole number.

Marge orders the following items and would like to leave a 20 percent tip based on her bill. There is no tax on her meal. What is the total cost of her dinner including gratuity? Item Amount Soup $3.75 Shrimp scampi $15.00 Iced tea $2.60 Dessert $4.25.
Answer:
The total cost of her dinner including tip would be $30.72
Step-by-step explanation:
Marge orders the following items on her meal.
Soup = $3.75
Shrimp scampi = $15.00
Iced tea = $2.60
Dessert = $4.25
The total cost of her dinner including gratuity is
3.75 + 15.00 + 2.60 + 4.25 = $25.60
She would like to leave a 20% tip based on her bill
Therefore, 20% of $25.60
= 0.20 × 25.60 = $5.12
Now add this tip amount to the bill amount.
$25.60 + $5.12 = $30.72
The total cost of her dinner including tip would be $30.72

A right rectangular prism has a square base and a height of 9 feet. its volume, v, is 144 cubic feet. what is the length of s, the sides of the base?
The length of the sides of the base of a rectangular prism is 4 feet.
Given that, a right rectangular prism has a square base and a height of 9 feet.
What is a rectangular prism?A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same.
Volume of a rectangular prism = Area of a base × Height.
Here, the volume of a rectangular prism = 144 cubic feet
Area of base = Area of a square = s²
So, 144 = s² × 9
⇒ s² = 16
⇒ s = 4 feet
Therefore, the length of the sides of the base of a rectangular prism is 4 feet.

In the United States the speed limit signs are in miles per hour. Unfortunately, your speedometer only reads in km/hour. How fast are you allowed to go if the speed sign says 70 mph (rounded to the nearest hundredth)
Answer:
The speed limit will be 112.65 kph.
Step-by-step explanation:
In order to find how fast one can go when speed sign says 70mph and the speedometer reads in km per hour we convert mph to kmph.
The conversion unit is 1mph= 1.609344kph
So 70mph = 70x1.609344=112.6541kph
Or 70mph=112.65 kph
One can travel at 112.65 kph.
