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.

(x-3)^2/64 + (y+5)^2/100 = 1

a. Identify the coordinates of the center of the ellipse.
b. Find the length of the major and minor axes.
c. Find the coordinates of the foci.
d. Graph the ellipse. Label the center and foci.,

Answers

Your ellipse is given in the form:
[tex]\frac{(x - xc)^{2} }{ a^{2} } + \frac{(y - yc)^{2} }{ b^{2} } = 1[/tex]

Indeed, you have:

[tex]\frac{(x-3)^{2} }{64} + \frac{(y+5)^{2} }{100} = 1[/tex]

Therefore you can easily find:

a) the coordinates of the center:
in your case xc = 3 and yc = -5
hence C(3 , -5)

b) lenght of the major and minor axis:
in your case a² < b²:
a² = 64 ⇒ a = 8 (ATTENTION! This is the semi-minor axis)
b² = 100 ⇒ b = 10 (again, this is the semi-major axis)
Therefore,
minor axis 2a = 16 and major axis 2b = 20

c) coordinates of the foci:
Since you have a² < b², foci have the generic coordinates F₁₂ (xc , yc+/-c)
where c = √(b² - a²)

Let's compute c = √(100 - 64) = √36 = 6
yf₁ = -5 - 6 = -11
yf₂ = -5 + 6 = -1
Therefore:
F₁ (3, -11) and F₂(3, +1)

Answers

You can consider the tree perpendicular to its shadow, therefore you get a triangle rectangle of which you know the two legs and you need to find the angle between the shadow and the hypothenuse, opposite to the tree.

In this case, the angle α can be easily found with trigonometry:
tan α = (opposite side / adjacent side)

Therefore:
α = tan⁻¹ (tree / shadow) = tan⁻¹ (10 / 14) = 35°

NOTE:
tan⁻¹ is sometimes found written as arctan.

Answers

A room's length is 3 feet less than twice its width. The area of the room is 135 sq feet. What are the room's dimensions?

Hope this helps:

A= L x W
135 = (2w-3)(W)
135 = (2w squared - 3W)
135 = 2w^2-3w
2w^2-3w-135 = 0
-----

Use the quadratic formula to get:
w = [3 +- sqrt(9 - 4*2*-135)]/4

Positive solution:
w = [3 + sqrt(1089)/4
w = [3 + 33]/4
w = 9 ft
L = 2W-3 = 2*9-3 = 15 ft.

If the width is w, the length is l = 2w-3.
The total area is length x width = w*(2w-3)
Solve
w*(2w-3)=135 to find w.
2w^2-3w-135=0

w = (3 +/- sqrt ( 9 +8*135))/4

The positive solution is
w = ( 3 + 33) /4 = 9 and then l = 15.

The dimensions of room are: Length = 15 feet and Width = 9 feet.

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:

Juliana and Maria logged a total of 90 hours working for their dad. Juliana worked 2 hours more than three times as much as Maria. How many hours did Juliana work?

Answers

Answer:
Juliana worked 68 hours

Explanation:
Assume the hours logged by Juliana is x
Assume the hours logged by Maria is y

We are given that:
1- Total hours logged by both is 90. This means that:
x + y = 90
This equation can be rewritten as:
x = 90 - y ...........> equation I

2- Juliana worked 2 hours more than 3 times as much as Maria. This means that:
x = 3y + 2 ...........> equation II

Substitute with equation I in equation II and solve for y as follows:
x = 3y + 2
90 - y = 3y + 2
88 = 4y
y = 22

Substitute with y in equation I to get x as follows:
x = 90 - y
x = 90 - 22
x = 68

Based on the above:
Hours logged by Juliana = x = 68 hours
Hours logged by Maria = y = 22 hours

Hope this helps :)

Let

x---------> the hours logged by Juliana

y---------> the hours logged by Maria

we know that

[tex]x+y=90[/tex] ---------> equation [tex]1[/tex]

[tex]x=3y+2[/tex] ---------> equation [tex]2[/tex]

Substitute equation [tex]2[/tex] in equation [tex]1[/tex]

Answers

3.75+15+2.6+4.25=$25.60 *1.2 = $30.72

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

cos(pi/3-pi/5) = cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(pi/3-pi/5)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(5pi/15-3pi/15)

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.

Answers

I'm guessing it's about 16 days.

Hope this helped!

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.

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?

Answers

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.

A sign standing 6 feet tall is situated 18 feet away from a flag pole. at a certain time of day the sign's shadow is 3 feet long and the flagpole's shadow is 24 feet long. how tall is the flagpole?

Answers

Observe attached picture.

On picture we have:
A = height of flagpole = x ft
B = length of flagpole's shadow = 24 ft
C = height of sign = 6 ft
D = length of sign's shadow = 3 ft

When we draw a picture representing this problem we can also add another line marked in red. This way we can see that we have two right-angle triangles. We can see that both have same angle marked with α.

We can apply trigonometry rules to find height of flagpole.

From small triangle containing sign we can find tangens function:
[tex]tan \alpha = \frac{C}{D} [/tex]
Similarly we can do for large triangle containing flagpole:
[tex]tan \alpha = \frac{A}{B} [/tex]

We see that these two equations have same left sides. This means that their right sides must also be same:
[tex]\frac{C}{D} = \frac{A}{B}[/tex]
We can solve for A:
[tex]CB=AD \\ A= \frac{CB}{D} \\ A= \frac{6*24}{3} \\ A=48 ft[/tex]

Height of flagpole is 48 feet.
