Answer:
Hi! I'm not quite sure what you entirely mean by this but I'll try to help. LxWxH is a formula used to find the volume of a rectangular prism or a box. If this is what you are using it for then there shouldn't a reason to divide. Unless maybe you're trying to find half of a box or you are trying to find the value of one of these in an equation but that's the only thing I can think of. Do you think you might be able to post an example in the comments?
Step-by-step explanation:
Consider the line 7x+5y=−2.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer: slope of a line perpendicular is [tex]\frac{5}{7}[/tex]; slope of a line parallel to this line is [tex]-\frac{7}{5}[/tex].
Step-by-step explanation:
Rewrite the line in y = mx + b form, where m is slope and b is y-intercept.
7x + 5y = -2
5y = -7x -2
y = [tex]-\frac{7}{5}[/tex]x - [tex]\frac{2}{5}[/tex]
The product of two slope of perpendicular line is -1.
Let x be the other line that perpendicular line with the line 7x + 5y = -2.
（[tex]-\frac{7}{5}[/tex])x = -1
x = [tex]\frac{5}{7}[/tex]
The slope of a line parallel to this line is the same, which is [tex]-\frac{7}{5}[/tex].
The Box is being packed without gaps or overlaps with unit cubes
The volume of a box is the product of its dimensions
The volume of the box is 11 unit cube
How to determine the volumeFrom the question, we have the following highlights
The cubes are unit cubesThe boxes are packed without gapsThe volume of a unit cube is:
Volume = 1 unit cube
There are 11 cubes in the box. So, the volume of the box is:
Volume = 11 *1 unit cube
Volume = 11 unit cube
Hence, the volume of the box is 11 unit cube

Show work for 100 POINTS!
Answer:
$204.95
Step-by-step explanation:
[tex]\mathsf{monthly \ payment=\dfrac{\frac{r}{12}\times P}{(1-(1+\frac{r}{12})^{-n}}}[/tex]
where:
P = total amount borrowedr = APR in decimal formn = total number of months of term of loanGiven:
P = 8711r = 14.5% = 0.145n = 5 × 12 = 60 monthsSubstituting given values into formula:
[tex]\implies \mathsf{monthly \ payment=\dfrac{\frac{0.145}{12}\times 8711}{(1-(1+\frac{0.145}{12})^{-60}}}[/tex]

Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 10 m, the new total area of the garden will be 169 m2. Find the length of each side of the original garden
Answer:
6m
Step-by-step explanation:
To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2

because if you graph the plots correctly you should get this
The equation of the graph of the polynomials is f ( x ) = x² ( x - a )⁵ ( x - b )
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x² ( x - a )⁵ ( x - b )
From the graph of the polynomial , we can see that
The critical points of the function f(x) = x² ( x - a )⁵ ( x - b ) are x = 0, x = a, x = b, and x = (7a + 5b)/3
Hence , the function is f ( x ) = x² ( x - a )⁵ ( x - b )

X3-Y3=28, X-Y=2, X2+XY+Y2=
it is = 14 but how?
Step-by-step explanation:
x³ - y³ = (x - y)³ + 3x²y - 3xy²
28 = (2)³ + 3xy(x - y)
28 = 8 + 3xy(2)
28 - 8 = 6xy
20 = 6xy → xy = 20/6 = 10/3
(x - y)² = 2²
x² - 2xy + y² = 4
x² - 2(10/3) + y² = 4
x² + y² = 4 + 20/3 = 32/3
x² + xy + y² = 32/3 + 10/3 = 42/3 = 14

First, create 3 equations of the form ax+by+cz=d , where a, b, c, and d are constants (integers between – 5 and 5). For example, x+2y-z=-1 . Perform row operations on your system to obtain a row-echelon form and the solution.
Go to the 3D calculator website GeoGebra: www.geogebra.org/3d?lang=pt and enter each of the equations.
After you have completed this first task, choose one of the following to complete your discussion post.
1. Reflect on what the graphs are suggesting for one equation, two equations, and three equations, and describe your observations. Think about the equation as a function f of x and y, for example, x+2y+1=z in the example above. Geogebra automatically interprets this way, that is, like z=f(x, y)=x+2y+1 , it isolates z in the equation.
Answer:
The solution is x=0, y=0, z=1
Step-by-step explanation:
Step1: -row2 + row1; -row2 + row3
x + 2y - z = -1
x + y + z = 1
x - y - z = -1

Solve the equation 3m – 10 = 5. Find the value of m
Answer:
So I don’t know if this is right cause yeha but I think that m=5
Step-by-step explanation:
we can substitute different numbers starting with one
Or this is the way I did we can do 10+5 which = 15
So that means 15/3=5
So m=5
also I don’t know if this is correct….:/
Answer:
m=5
Step-by-step explanation:
step 1:letters to the left side of the =, numbers to the right (If there are numbers attached to the letter, keep it on the left) if a number is being taken to the right, change the sign to the opposite of what it was
3m= 5+10
step 2: add the numbers on the right
3m=15
step 2: divide both sides by 3 to get m alone
m=5
4,000 i savings at end of 3 years earn 960 in simple interest how much in account
Answer:
She would have had $120 more should the rate were 1% greater.
Step-by-step explanation:
At the end of 3 years the amount in the account = Principal + Interest
Amount = 4000 + 960 = 4960
Amount at the end of 3 years = $4960
b) Formula for Rate , R = 100I/(PT)
Where I = Interest = 960, P = Principal = 4000, T= Time = 3 years
R = (100 × 960) / ( 4000 × 3)
R = 8
Rate, R = 8% per annum.
c) If the rate was 1% more, R = 8 + 1 = 9% per annum
Interest, I = PRT/100
Interest, I = 4000 × 9 × 3 /100 = 1080
Amount in her account would have been = $4000 + $1080 = $5080
Amount more = $5080 - $4960 = $120
Aiko works in the fish department of a pet store. She is asked to drain, clean, and refill two reef tanks.
The first tank holds 175 gallons of water and the second tank holds 200 gallons of water. The hoses that
she uses drain the tanks at a rate of 25 gallons of water per hour.
1. write an equation for each tank that represents the total amount of water in the gallons in the tank in terms of the number of hours that the tanks are draining
tank one equation ________
tank two equation ________
2. how much water is in each tank after 3 hours?
tank one ___
tank two___
The equation for the first tank will be 175 - 25h and the equation for the second tank is 200 - 25h.
How to solve the equation?From the information given, the first tank holds 175 gallons of water and the second tank holds 200 gallons of water while the hoses that she uses drain the tanks at a rate of 25 gallons of water per hour.
Therefore, the equation for the first tank will be:
= 175 - (25 × h)
= 175 - 25h
The equation for the second tank will be:
= 200 - (25 × h)
= 200 - 25h
The quantity in the first tank after three hours will be:
= 175 - 25h
= 175 - (25 × 3)
= 175 - 75
= 100 gallons.
The quantity in the second tank after three hours will be:
= 200 - 25h
= 200 - (25 × 3)
= 200 - 75
= 125 gallons.
