The cube root of r varies inversely with the square of s. Which two equations model this relationship?
Step-by-step explanation:
³√r =(k×1/s²)
³√r = k/s²
The equation given in the option which shows the relationship given in the question is ∛r = k/s²and [tex]\rm s^2 r^{1/3} = k[/tex], the correct options are B and C.
What is Inverse Variation?When a variable varies inversely with the other variable, i.e. on increasing one variable the other decreases is called Inverse Variation.
The statement for modelling the relation is
The cube root of r varies inversely with the square of s.
∛r ∝ (1/s²)
∛r = k/s²
Here k is the proportionality constant
The equations which model this relationship is given by ∛r = k/s²and [tex]\rm s^2 r^{1/3} = k[/tex].

Dan was thinking of a number. Dan divides by 5, then adds 3 to get an answer of 3. What was
the original number?
Answer:
The original number was: x = 0
Step-by-step explanation:
Let 'x' be the number
Given that:
Dan first divides it by 5
x/5
Then adds 3
x/5 + 3
To get an answer of 3
x/5 + 3 = 3
now solving the expression
[tex]\frac{x}{5}+3=3[/tex]
Subtract 3 from both sides
[tex]\frac{x}{5}+3-3=3-3[/tex]
Simplify
[tex]\frac{x}{5}=0[/tex]
Multiply both sides by 5
[tex]\frac{5x}{5}=0\cdot \:5[/tex]
Simplify
[tex]x=0[/tex]
Therefore, the original number was: x = 0

Lucas bought square tiles to retile the
lobby of Town Travel Agency. Each
side of a tile is 11 inches long. If Lucas
uses the formula for the area of a
square, A = s2, how many square
inches will each tile cover?
00 ft.?
Answer:
121 in² ; 0.840 ft²
Step-by-step explanation:
Given that:
Side length of square tile, s = 11 inches
The Area of a square = a² ;
Where a = side length
Hence, we Can get the area of the square tile using the area of square formula :
Area of square tile = 11² = 121 in²
Area in feets :
1 ft² = 144 in²
x = 121 in²
144 x = 121
x = 121 / 144
x = 0.840 ft²

Answer: the answer is D
Step-by-step explanation:I had that question on a quiz
The points after dilation is (27, 18).
What is Dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.
Enlargements are dilations that result in a larger image. Reduction is the name for a dilatation that shrinks the image. The initial figure is stretched or contracted by a dilatation.
Given:
Scale Factor= 3
Points (9, 6).
If the coordinates is dilated by factor 3.
Then, (9, 6).
= (9(3), 6(3)).
= (27, 18)
Hence, the points after dilation is (27, 18).

The value of n is 5 + 8/y for that expressions (3y + 1) + (2y + 8) and (ny + 9) are equivalent.
What is an algebraic expression?An algebraic expression is consists of variables, numbers with various mathematical operations.
The given expressions are (3y + 1) + (2y + 8) and (ny + 9)
Also, both the expressions are equivalent to each other.
To find the value of n, equate expressions (3y + 1) + (2y + 8) and (ny + 9),
3y + 1 + 2y + 8 = n y + 1
5y + 9 = n y + 1
5y + 9 - 1 = n y
5y + 8 = n y
n = (5y + 8) / y

Your dinner costs $21.50 before tax. If you used a fifteen percent off coupon
and then you are charged seven percent sales tax, what is your balance with tax?
Answer:
$19.55
Step-by-step explanation:
Discount = 15% of 21.50
= 0.15 * 21.50
= 3.225
= $ 3.23
Balance need pay = 21.50 - 3.23 = $ 18.27
Tax = 7% of 18.27
= 0.07 * 18.27
= $1.28
Balance with tax = 18.27 + 1.28 = $ 19.55

Jayson has 97 tickets to give away. He gave 4 tickets to each student in his class and has one leftover.
How many students in his class?
Answer:
4 ; 24
Step-by-step explanation:
A.)
Fixed fee, x = $5
Hourly rate, y = $3
Total rent fee, t= $17
Number of rent hours :
$17 = $5 + $3y
17 - 5 = 3y
12 = 3y
y = 12/3
y = 4 hours
B.)
Total Number of tickets , t = 97
Tickets per student, r = 4
Tickets left = 1
Number of students in class:
(97 - 1) / 4
96 /4
= 24 students

Which system of inequalities is shown?
A y<x y>4 B y>x y
Given:
The graph of the system of inequalities.
To find:
The system of inequalities.
Solution:
In the given graph, we have two dotted boundary lines.
First boundary line is passes through (-1,1), (0,0) and (1,1), so it represents a proportional relationship and the equation of this boundary line is
[tex]y=x[/tex]
Second boundary line is a horizontal line passes through the point (0,4). So, the equation of this boundary line is
[tex]y=4[/tex]
Shaded portion lies below these boundary line and these boundary lines are dotted. So, the sign of inequity must be <.
The system of inequalities is
[tex]y<x[/tex]
[tex]y<4[/tex]

For the system of equations that follows, use Gaussian elimination to obtain an equivalent system whose coefficient matrix is in row echelon form. Indicate whether the system is consistent. If the system is consistent and involves no free variables, use back substitution to find the unique solution. If the system is consistent and there are free variables, transform it to reduced row echelon form and find all solutions.
