Answers
2048 people would fill the stadium to its full capacity
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that a stadium is filled to 80% capacity
There are 2,560 people are in the stadium
We need to find how many people would fill the stadium to its full capacity.
We have to convert 80% to decimal by dividing 2560 with 100
80/100
0.8
Now multiply 0.8 with 2560
0.8×2560
2048
Hence, 2048 people would fill the stadium to its full capacity

Which expression is the factored form of 2x^2 7x 3?
Answers
The factored form of quadratic equation 2x² + 7x + 3 is 2(x + 1/2) (x + 3)
A quadratic equation can be expressed in:
- Standard form: y = ax² + bx + c
- factored form: y = a(x - x₁) (x - x₂)
Here, x₁ and x₂ are the roots of the given function.
Suppose we are given a quadratic equation:
y = ax² + bx + c
To find the factored form, use the following properties:
x₁ . x₂ = c/a
x₁ + x₂ = - b/a
In this case, the quadratic function is:
y = 2x² + 7x + 3
We have to find x₁ and x₂ such that:
x₁ . x₂ = 3/2
x₁ + x₂ = - 7/2
Hence,
x₁ = - 1/2
x₂ = - 3
Therefore the factored form is:
y = 2(x + 1/2) (x + 3)

is the relationship between the variables in the table an inverse variation or a direct variation? write an equation to model it.
x= 2 6 7 14
y= 21 7 6 3
Answers
The relationship between the variables in the table is an inverse variation The equation to model is y = 42/x.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 8 is an equation.
We have,
x: 2 6 7 14
y: 21 7 6 3
Now,
When x = 2, y = 21
This can be written as,
y = kx
21 = 2k
k = 21/2
The equation is y = (21/2)x _____(1)
or
y = k/x
21 = k/2
k = 42
The equation is y = 42/x _____(2)
Now,
We will check which equation fits the table.
From (1)
y = (21/2)x
When x = 6,
y = (21/2) x 6 = 21 x 3 = 63
From (2),
When x = 6,
y = 42/6 = 7
When x = 7,
y = 42/7 = 6
When x = 14,
y = 42/14 = 3
This equation satisfies the table.
Thus,
The relationship is an inverse variation.
The equation is y = 42/x.

Answers
Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11 gets 3a³ + 4a² - a + 5.
The answer in descending powers of a is 3a³ + 4a² - a + 5.
A polynomial is a mathematical expression consisting of a sum of powers in one or more variables (indeterminates) with non-negative integer exponents.
Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11
(3a³ + 8a - 6) + (4a² - 9a + 11) = 3a³ + 4a² - a + 5
The coefficients of a³, a², a and 1 is 3, 4, -1 and 5 respectively.
Descending powers of a in the polynomial is a³, a², a. So the answer in descending powers of a is 3a³ + 4a² - a + 5.

If $x$ is a positive multiple of 8 and $x^2>100$, but $x<20$, what is $x$?
Answers
Answer:
16
Step-by-step explanation:
16 is a positive multiple of 8, in which 16²=256>100 and 16<20 are true statements.
Answer:
[tex]$x=\boxed{16}$[/tex]
Step-by-step explanation:
Since $x$ is a positive multiple of 8, it must be at least 8. Since $x^2>100$ and $x$ is at least 8, the only solution is $x=16$.
To verify this, note that $x=8$ does not satisfy the inequality $x^2>100$, but $x=16$ does, so $x=16$ is the only solution that works.
Therefore, $x=\boxed{16}$.

Eight candy bars cost $6.00. How many candy bars cost $27.00?
Answers
Answer:
36 candy bars. (32 if sold in packs)
Step-by-step explanation:
We know that eight candy bars cost 6 dollars, and we purchased $27 dollars worth of them.
Therefore, we can use 27/6 = 4.5 to see how many packs/sets of candy bars we purchased. Since there are 8 in a pack/set, we do 8x4.5 = 36 to see we can purchase 36 candy bars. However, if you can only buy them in packs of 8, then you can only purchased 4 packs/32 bars since 6x5 = 30 and we only have 27 dollars.
