Answer: The amount of long will it take the plant to grow is [tex]5\frac{2}{7}[/tex] weeks.
Step-by-step explanation:
Given data,
A certain days plant grows 1 1/6 inches
It take the plant to grow 6 1/6 inches
Let us assume,
A certain days plant grows = x
It take the plant to grow = y
So ,
we can write,
x = 1 and 1/6
x = 1*1/6
L.C.M is '6',
Then,
x = (6+1) / 6
x = 7/6
Then,
y = 6 and 1/6
y = 6*1/6
y =(1+36) / 6
y = 37/6
So, divide y/x = (37/6) / (7/6)
= 37/6 * 6/7
L.C.M is 42
= 222/42
= 5 12/42
= 5 2/7 weeks
Therefore,
The amount of long will it take the plant to grow is [tex]5\frac{2}{7}[/tex] weeks.

Which equation below combines with the equation -4 x+6 y=3 to form a system with an infinite number of solutions?
A. 0.5+x=1.5 y
B. 0.75+2 x=1.5 y
C. 0.5+2 x=1.5 y
D. 0.75+x=1.5 y
To form a system with an infinite number of solutions, the equation -4x + 6y = 3 must be combined with D. 0.75 + x = 1.5 y.
A system of equations is a set of two or more equations which includes common variables.
To form a system with an infinite number of solutions, the lines should be the same or overlapping. These lines must have the same slope and y-intercept. The equations of these lines must be the multiple of one another.
Given the equation -4x + 6y = 3, rewrite this in the form c + ax = by(same as the form of the choices).
-4x + 6y = 3 ⇒ 3 + 4x = 6y
To make 6y into 1.5y, divide both sides by 4.
3 + 4x = 6y ⇒ 0.75 + x = 1.5 y
Hence, the equation -4x + 6y = 3 must be combined with 0.75 + x = 1.5 y to form a system with an infinite number of solutions.

A triangle has three interior angle measures; x is the largest angle, y is the next largest angle, and z is the smallest angle.
The measure of the largest angle is 40 degrees less than the sum of the measure of the other two angles.
The largest angle is twice the smaller angle minus 30 degrees.
The sum of the triangle's interior angles is x + y + z = 180.
Which two equations represent the remaining angle relationships?
Select each correct answer.
1) x=y−z+40
2) x=2z−30
3) x=y+z−40
4) x=30−2z
5) x = y + z + 40
The correct answer would be option 2 and 3:
2) x=2z−303) x=y+z−40How to solve for the anglesWe have to sove the problem by carefully trying to understand the statements
x = largest angle
y = next largest angle
z = smallest.
1. For the first statement: The measure of the largest angle is 40 degrees less than the sum of the measure of the other two angles.
largest angle < y + z
This would be represented as
x = y + z - 40
2. The largest angle is twice the smaller angle minus 30 degrees.
This is represented as
2 times of smallest = 2 * z = 2z
minus 30 degrees = 2z - 30

Find the distance between each pair of parallel lines with the given equations.
y=-2 x+1 y=-2 x+16
The distance between each pair of parallel lines with the given equations y = -2x+1 and y = -2x+16 is 15 units.
We can find the points passing through the lines.
Hence,
The points passing through the line y = x - 11 are:-
Let x = 0
y = -2(0) +1
(0,1)
and;
Let x = 1/2
y = -2(1/2) + 1 = -1 +1
(-1/2,0)
The points passing through the line y = -2x + 16 are:-
Let x = 0
y = -2(0) + 16 =16
(0,16)
and;
Let x = 8
y = -2(8) + 16 = -16 + 16
(8,0)
Hence, using distance formula, the distance between the parallel lines will be:-

1. Factor the expression: x^6–729. Show your work for full credit.
2. Solve the equation 2x^2+16x–11= -7 by completing the square. Show your work for full credit.
3. Factor over the complex numbers. Show your work for full credit. x^4–5x^2–36
1) Factorizing the expression x⁶ - 729 is; (x + 3)(x - 3)(x⁴ + 9x² + 81)
2) Solving the equation 2x² + 16x – 11 = -7 by completing the square is; x = -4 + √18 or -4 - √18
3) Factorizing x⁴ – 5x² – 36 over the complex numbers is; (x + 3i)(x - 3i)(x + 2)(x - 2)
How to factorize expressions?
1) We are given the expression; x⁶ - 729
It can also be written as;
(x²)³ - 9³
Now, from factorization of algebra, we know that;
a³ - b³ = (a - b)(a² + ab + b²)
Thus;
(x²)³ - 9³ = (x² - 9)((x²)² + 9x² + 9²)
= (x² - 9)(x⁴ + 9x² + 81)
= (x + 3)(x - 3)(x⁴ + 9x² + 81)
2) We want to solve the equation 2x² + 16x – 11 = -7 by completing the square.
Add 7 to both sides to get;
2x² + 16x – 11 + 7 = -7 + 7
2x² + 16x – 4 = 0
Divide through by 2 to get;
x² + 8x – 2 = 0
Add 2 to both sides to get;
x² + 8x = 2
Take half of the x term and square it and then add the result to both sides to get;
x² + 8x + 16 = 2 + 16
Rewrite the perfect square on the left to get;
(x + 4)² = 18
Take square root of both sides to get;
x + 4 = ±√18
Subtract 4 from both sides to get;
x = -4 ± √18
x = -4 + √18 or -4 - √18
3) We want to factorize x⁴ – 5x² – 36
Using the difference of squares identity, we know that;
a² - b² = (a + b)(a - b)
Thus;
x⁴ – 5x² – 36 = (x² + 9)(x² - 4)
Now, (x² + 9) factored over the complex numbers gives;
(x² + 9) = (x + 3i)(x - 3i)
Thus;
x⁴ – 5x² – 36 = (x + 3i)(x - 3i)(x + 2)(x - 2)

Find the geometric mean between pair of numbers.
3√5/4 and 5√5/4
The geometric mean of 3√5/4 and 5√5/4 is 5√3/4.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Solving for the geometric mean between 3√5/4 and 5√5/4 using the formula:
GM = n√x1 x2 . . . xn
where n = 2, x1 = 3√5/4, and x2 = 5√5/4
GM = √(3√5/4)(5√5/4)
GM = √(75/16)
GM = 5√3/4
Hence, the geometric mean of 3√5/4 and 5√5/4 is 5√3/4.

Answer:
Step-by-step explanation:
Rate: 54000 brochures per hour
Formula: D=RT Distance=Rate x Time (In this case distance is the amount)
(I’m not sure if you meant to type 3 1/4 or 314. I’ll include both)
D=54,000(3 1/4)
Two ways
1. 54,000(3 1/4)=175,500
2. 54,000x3 is 162,000, and 1/4 of 54,000 is 54,000/4=13,500. 162,000+13,500=175,500.

Which statements prove that m || n?
Answer:
The first 2 and the 2nd to last equations
Step-by-step explanation:
Angles 8 and 10 are alternate interiors, which would only work if m and n are parallel.
Angles 1 and 9 are congruent angles, which would only work if m and n are parallel.
Angle 1 and 3 are on the same line, so that can't prove it.
m8 and m9 could only add up to 180 if m and n are parallel, which makes this also true.
Angles 7 and 10 add up to 180, but can't be congruent.

Using least common multiple (LCM), the Vasquez family both visit their grandmother and host the neighbor hood party after 24 weeks. After 48 weeks, all three events will occur at the same time.
A common multiple is defined as a whole number, that is a shared multiple of each set of numbers. The least common multiple (LCM) of two integers is the smallest positive integer that is divisible by both numbers.
If the Vasquez family visit their grandmother every 3 weeks and host a neighbor hood party every 8 weeks, to know when will these event will occur at the same time, solve for the LCM of 3 and 8.
3 : 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, . . .
8 : 8, 16, 24, 32, 40, . . .
LCM = 24
Hence, after 24 weeks, both will occur at the same time.
To know when will the three events will occur at the same time, solve for their LCM.

Suppose a total of 15 ounces of medicine is added to the original mixture (so that the total volume is now 25 ounces with 18 ounces of medicine and 7 ounces of water). How much water must now be added so that the mixture has the same proportion of medicine and water as the original mixture?
We have to add 35 ounces of water to the mixture to make the proportion of medicine and water same as the original mixture.
Given,
The quantity of medicine added to the original mixture = 15 ounces
New quantity of medicine in the mixture = 18 ounces
Quantity of water in the mixture = 7 ounces
Total new quantity of mixture = 18 + 7 = 25 ounces
Original quantity of medicine in the mixture = 18 - 15 = 3 ounces
Original quantity of water in the mixture = 7 ounces
Total original quantity of mixture = 3 + 7 = 10 ounces
We have to find the amount of water to add into the new mixture to make the proportion of medicine and water same as the original mixture.
Here,
Proportion of medicine and water in original mixture = 3:7
Quantity of medicine and water in new mixture = 18:7
Now,
18 ÷ 3 = 6
Then, 7 × 6 = 42
So, 42 - 7 = 35
Therefore, we have to add 35 ounces of water to the mixture to make the proportion of medicine and water same as the original mixture.
