The given equation 5n – 6 > 8n – 3n does not satisfy the inequality conditions.
What is referred as inequality?In mathematics, an inequality is a connection between two expressions as well as values that aren't equal to each other. Inequality results from a lack of balance.a statement of an order relationship among two numbers or algebraic expressions (greater than, greater than or comparable to, less than, or less than or equal to).The given inequality is;
5n – 6 > 8n – 3n
Ad 3n on the both side of inequality.
5n – 6 + 3n > 8n – 3n + 3n
Now, subtract the variable part,
8n - 6 > 8n
Subtract 8n both side.
8n - 6 - 8n > 8n - 8n
0 - 6 > 0
-6 > 0
But, -6 not not greater than 0.
Thus, the inequality is not valid.

Yes , the given logarithm is a common logarithmic.
A base 10 logarithm is a common logarithm.It is also known as decimal logarithm and is named after its base. It is also known as the Briggs logarithm, and the "standard logarithm", after Henry Briggs, the English mathematician who pioneered its use.Calculators usually say "logarithm", but mathematicians usually mean the natural logarithm (the logarithm with base e ≈ 2.71828), not the common logarithm when writing "logarithm". To reduce this ambiguity [tex]log_{10}x[/tex] should be written lg(x) and [tex]log_ex[/tex] must be ln(x).We have given an logarithm function which is [tex]log_{10}100[/tex] ..... (1)

Ilana says that a fraction with a prime number in the numerator is always in simplest form. Is Ilana correct? Explain.

She is correct.
In order to turn a fraction into its simplist form, you need to not be able to divide the numerator or the denominator by ANY integer. A prime number is not divisible by anything, so it is its simplist form.
Find the midpoint and distance for each:
1. A(0, 0) & B(8,4)
The midpoint between two points A(0,0) and B(8,4) is (4,2)
The distance between two points A(0,0) and B(8,4) is 4√5
To find the midpoint of two points,
We need to take an average of both the x and y components of both points
Two points A(x ₁,y₁) and B(x₂ ,y₂) are (0,0) and (8,4) respectively
Let M be the mid-point M(x, y),
x = x₁+x₂/2
= 0+8/2
= 8/2
= 4
Similarly
y = y₁+y₂/2
= 0+4/2
= 4/2
= 2
So, the midpoint of the two points A(0,0) and B(8,4) is (4,2)
To find the distance between two points,
We need to take the square root of the difference square of x and y, which is
d² = Δx² + Δy²
d = √(Δx²+Δy²)
Δx = x₂-x₁
= 8-0
= 8
Δy = y₂-y₁
= 4-0
= 4
Thus,
d = √(8²+4²)
d = √(64 + 16)
d = √80
d = 4√5
So the distance between the two points is 4√5

The percentage of people living on boat in Florida is 15.4%. The equivalent of this percentage to decimal is 0.154 and to fraction is 77/500.
55% live in a house, 25% live in an apartment, 4.6% in condo while the rest live on a boat. If all the percentages are summed up, they must be equal to 100%.
Let a% equals to the percentage of adult living on boat
55+25+4.6+a = 100
84.6 + a = 100
Collect like terms
a = 100 - 84.6
a = 15.4%
Therefore, the percentage of adult living on boat is 15.4%
To convert the percentage to decimal equivalence, one must divide it by 100%
15.4%/100%
= 15.4/100
= 0.154
To convert the percentage to fraction equivalence, one have to divide it by 100%
15.4%/100%
= 15.4/100
One has to make both the numerator and denominator of the fraction whole numbers, to do that one has to shift the decimal place behind the last digit, for a number without decimal point a 0 is added to the back of the number.

An oceanic -oceanic convergence give rise to volcanic island arcs.
When one oceanic plate subducts another, oceanic-oceanic convergence occurs, leading in the creation of volcanic islands and trenches.Volcanic arcs are volcanoes that originate over a subducting plate and have the shape of an arc. Volcanic activity along a subduction zone, which happens when an oceanic plate falls beneath an oceanic or continental plate, leads to volcanic island arcs.What kind of convergence results in the arcs of volcanic islands?
A volcanic island arc is created when two oceanic plates collide, with the older and heavier of the two subducting beneath the other to start volcanic activity. This process is similar to what happens in an oceanic-continental convergent plate boundary.Learn more about volcanic island arc

In the cuboid, the line segment parallel to AD is BC as they both lie on same plane and are directed in same direction.
What are parallel lines?Two lines are said to be parallel if they lie on the same plane and are directed towards the same direction.
Given in the question is a labelled cuboid.
From the definition of parallel lines, they should lie on the same plane. Therefore, we will eliminate EB and EH because they don't lie in the plane of AB. CD lies in the plane of AB, but is directed perpendicular to AB. BC is in the same plane in which AB lies and is also directed in the direction of AB.

A rectangular garden has an area of 3m - 7m - 6.
Use the dimensions from Part A to determine an expression that gives the perimeter of the garden.
Reminder: P = 2L + 2W.
The perimeter of the whole figure includes the sum of the side lengths and the value is -2 - 4m units
What are areas?The area of a shape is the amount of space on the shape.
For most regular shapes, the area is the product of their width and the length
How to determine the expression for the perimeter of the figure?The area of this rectangle is given as
Area = 3m - 7m - 6
Evaluate the like terms
So, we have
Area = -4m - 6
The common factor of 4 and 6 is 2
So, we have the following equation
Area = 2(-2m - 3)
The area of the rectangle is
Area = Length * Width
So, we have
Length, L = 2
Width, W = -2m - 3
The perimeter of the rectangle is calculated as
P = 2 x (L + W)
So, we have
P = 2 x (2 - 2m - 3)
Evaluate the like terms in the above expression
So, we have
P = 2 x (-1 - 2m)
Open the bracket in the above expression
So, we have
P = -2 - 4m
Hence, the perimeter of the whole figure is -2 - 4m units

When making lasagna, Mr. Singleton uses 1 pound of sausage for every 3/4 of a pound of mozzarella cheese. For a dinner party, Mr. Singleton wants to make an extra lasagna with 1 pound of mozzarella cheese. How much sausage will he need?
Using ratio we can calculate that Mr. Singleton used approximately 1.33 pounds of sausage .
A ratio demonstrates how frequently one number is found within another. For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.
A ratio can therefore be thought of as an ordered pair of integers, a fraction with the first number in the numerator and the second in the denominator, or as the value represented by this fraction. Ratios of counts that are expressed in terms of (non-zero) natural numbers are rational numbers and occasionally natural numbers as well. The ratio of two numbers is a dimensionless number when they are measured using the same unit, which happens frequently. A rate is the product of two quantities that are divided by their respective units of measurement.He uses 1 pound sausage for every 3/4 pound of cheese.
Ratio of sausage to cheese = 1 : 0.75 = 4 : 3 .
Now he uses 1 pound of cheese therefore let he uses x pounds of sausage.
Now using ratio:
x : 1 = 4 : 3
or , x / 1 = 4 / 3
or, x = 1.333..
or, x ≈ 1.33 pounds
Hence he uses 1.33 about pounds of sausage
