you take a break from doing your physics homework and go to the grocery store to buy pasta. the store is out of your favorite kind of pasta so, instead, you buy pasta that is the same shape as your usual pasta but is twice as big in every dimension (twice as long, twice as wide, etc.). one box of the bigger pasta pieces has the same net weight as one box of your usual pasta.
In linear equation, oil required to cover oil all the pieces in one box of big pasta with same thin layer of oil = 1/2 of the oil.
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Let the dimensions of one piece of your favorite kind of pasta be l, b, h.
Volume of one piece of pasta = l b h
Surface area of one piece of pasta = 2( lb + bh + lh)
Let the no of pasta piece in the box ( favorite one ) be 'n' = .
Total volume = n × lbh
Total Surface area = n . 2( lb + bh + lh)
In the bigger size pasta box dimensions of one piece of of pasta 2l , 2h , 2b .
∴ Volume of one piece of pasta = 2l × 2b × 2h = 8lbh
Surface area of one piece of pasta = 2( 4lb × 4bh × 4lh)
= 2 × 4 ( lb × bh × lh )
Let the no of pasta pieces in the bigger pasta box in m.
Total volume of pasta = m × 8lbh
total surface area = m . 4 × 2 ( lb × bh × lh )
the total volume of pasta is also same in the box.
mass = density × volume
D × m .8 lbh = D × n . lbh
m = n/8
total surface area of pastas in bigger pasta box = m × 4 × 2 ( lb × bh × lh)
= n/8 × 4 × 2 ( lb × bh × lh )
= n/8 × 1/2 × n× 2 ( lb × bh × lh )
= 1/2 × surface area (total) of small pasta
∴ oil required to cover oil all the pieces in one box of big pasta with same thin layer of oil = 1/2 of the oil

Determine which integers in the set S: {−2, −3, −4, −5} will make the inequality 3p − 10 ≥ 7p + 6 true.
The integers in the solution set of 3p − 10 ≥ 7p + 6 are -4 and -5
What are inequality expressions?Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
How to determine the integers in the set?The set is given as
S: {−2, −3, −4, −5}
The inequality expression is given as
3p − 10 ≥ 7p + 6
We start by evaluating the inequality expression
So, we have
3p − 10 ≥ 7p + 6
Subtract 7p from both sides of the inequality expression
So, we have
-4p − 10 ≥ 6
Add 10 to both sides of the inequality expression
So, we have
-4p ≥ 16
Divide both sides of the inequality expression hy -4
So, we have
p ≤ -4
This means that the integers in the solution set are integers that do not exceed -4
These integers are -4 and -5
Hence, the solution is -4 and -5

if r and s are integers and an expression of the form (x − r)(x − s) is multiplied out, a quadratic polynomial with integer coefficients is obtained. for instance, (x − 2)(x − 7)
The quadratic expression when ( x - 2) ( x - 7 ) is multiplied is x² - 9x + 14.
A polynomial of degree two or a quadratic polynomial that has two as the highest exponent of the variable. A quadratic polynomial will typically have the following form: p(x): ax² + bx + c, a ≠ 0.
A coefficient is a multiplicative factor in a polynomial term, a series term, or an expression; it often has the form of a number but can also take the form of any expression.
When an expression ( x - r )( x - s ) is multiplied, where r and s are integers, we obtain a quadratic polynomial.
Therefore, when ( x - 2 )( x - 7 ) is multiplied we get:
( x - 2 )( x - 7 ) = x( x - 7 ) - 2( x - 7 )
( x - 2 )( x - 7 ) = x² - 7x - 2x + 14
( x - 2 )( x - 7 ) = x² - 9x + 14

A fashion photographer needs to hire a stylist to prepare his models.
Let the number of hours stylist take = x
Jayla charges $156 for showing up, plus $63 per hour. So, this can be mathematically written as ,

How to determine the properties of equality applied in solving the equation?The complete question is added at the end of the solution
From the complete question, the equation is given as:
(1/3d + 4 = 28)
Start by removing the bracket in the given equation
So, we have
1/3d + 4 = 28
Next, we continue by applying the subtraction properties of equality
This means that we subtract 4 from both sides of the equation.
So, we have:
1/3d + 4 - 4= 28 - 4
Evaluate the difference in the above equation
So, we have
1/3d = 24
Next, we continue by applying the product properties of equality
This means that we multiply both sides of the equation by 3
So, we have:
3 * 1/3d = 24 * 3
Evaluate the products in the above equation

Where:
aₙ is the nth term of a geometric sequence.r represents the common ratio.a₁ represents the first term of a geometric sequence.For this exercise, we would formulate an equation from the common ratio of this geometric sequence as follows:
r = a₂/a₁ = a₃/a₁
Substituting the given parameters into the common ratio formula, we have;

Next, we would take the square of both sides, we have:
1/x + 1 = x - 1/1
Cross-multiplying, we have:
(x + 1)(x - 1) = 1
x² - x + x - 1 = 1
