What’s a better buy? 80 marbles for $4.99 or 90 marbles for $5.99?
80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99
What is comparison in mathematics?
Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given are 80 marbles for $4.99 and 90 marbles for $5.99.
Using Unitary method -
80 marbles cost → $4.99
1 marble will cost → (4.99/80) = $0.062
90 marbles cost → $5.99
1 marble will cost → (5.99/90) = $0.066
Clearly $0.062 < $0.066
So, 80 marbles for $4.99 is a better buy.
Therefore, 80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99

What are the solutions of this quadratic equation?
X^2 = 16x – 65
Answer:
x= 4.3125
Step-by-step explanation:
Answer:
x=4+7i and x=4-7i
Step-by-step explanation:
Rewrite the given quadratic equation by completing the square.
x^2-8x=-65
x^2-8x+16=-65+16
x^2-8x+16=-49
(x-4)^2=-49
Now, solve the equation by applying the square root property and isolating x.
(x-4)^2=-49
√(x-4)^2 = √-49
x-4=+7i
x=4+7i
So, the solutions to the given quadratic equation are x+4+7i and x=4-7i.

A ticket to see your favorite baseball team cost $43.32. The price decreases by $0.25 for every game loss during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 24 games. What is the price of a ticket after the team loses 24 games?
Answer:
$37.82Step-by-step explanation:
Given that the cost of the ticket is
$43.32
and the price decrease is by $0.25
let the cost be C
and let the number of losses be L
the expression for the cost we be
C=43.32-0.25L
for the number of losses which is 22 we have
C=43.32-0.25(22)
C=43.32-5.5
C=37.82
Therefore the price after 22 losses is $37.82

Answer:
The students can make 70 pieces of ornament from the 5 pieces of Bristol board from the cupboard.
Step-by-step explanation:
Since each student takes 14 of a piece of Bristol board to make an ornament, and we have 5 pieces of Bristol board in the cupboard, this implies that we require 1 Bristol board makes 14 pieces of ornament. Therefore 5 pieces of Bristol Board will make 5 × 14 pieces of ornament = 70 pieces of ornament.
So, the students can make 70 pieces of ornament from the 5 pieces of Bristol board from the cupboard.

That is what mine showed for the same question and answer options.
As x approaches positive infinity, m(x) approaches positive infinity.
As x approaches negative Infinity, m(x) approaches negative Infinity.
The function f(x) = x^3 has been transformed m(x) = 1/3x^3+ 6. Than the blank space to be field.
Range of the function is the output value of the function.
Here, f(x) = x^3 transformed to m(x) = 1/3x^3+ 6,
The range of the transformed function is given by for its Domain x = (-∞,∞) is (-∞, ∞).
Thus, the range of the of m(x) for x =(-∞, ∞) is (-∞, ∞).

What is inequality?
In mathematics, an inequality is a relationship that compares two numbers or other mathematical expressions unequally.[1] It is most often used to compare two numbers by their size. Several different notations are used to denote different types of inequality:
The notation a < b means that a is less than b.
Notation a > b means that a is greater than b.
In both cases, a is not equal to b. These relationships are known as strict inequalities,meaning that a is strictly less than or strictly greater than b. Equivalence is excluded.
Unlike strict inequalities, there are two types of inequalities that are not strict:
The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or equivalently at most b or not greater than b).
The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or equivalently at least b or not less than b).
A ratio that is not greater than can also be represented as a ≯ b, with the "greater than" symbol separated by a slash "not". The same is also true for no less than and a ≮ b.
The notation a ≠ b means that a is not equal to b; this difference is sometimes considered a form of strict inequality.It does not say that one is greater than the other; it does not even require that a and b be members of an ordered set.
Here given,[tex]2x < 10[/tex]
We want to find solution set of 2x < 10
Now,2x < 10
First we are dividing both side by 2 and get,
