15 dance tickets were sold in one half hour. If this rate continues, how many hours would you expect it to take to sell 270 tickets?
First, you would divided 270 by 15
270 ÷ 15 = 18
Then, you would divide 18 by 2 because it only takes half an hour to sell 15.
18÷2 = 9
Therefore, it would take 9 hours!
-----
Another Way!
First, multiply 15 by 2 because it only takes half an hour to sell 15.
15×2 = 30
Then, divide 270 by 30!
270÷30 = 9
Therefore, it would take 9 hours!

Ethan uses the function f(x) = 2x2 + 2x + 4 to track the temperature of a substance over 8 hours. You know that f(3) = 28 meaning that the temperature of the substance is 28°C when you plug in a 3 for x. What is the domain of Ethan’s function?
The domain of the function f(x) = 2x² + 2x + 4 is (-∞, ∞).
What is Quadratic equation?The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of:
ax² + bx + c = 0
where x is the unknown variable and a, b and c are the constant terms.
You have the quadratic function
f(x) = 2x² + 2x + 4 ,
and remember that all quadratic functions are parabolas opening at point called the vertex.
Since you can plug any real number in our parabola here, its domain is all the real numbers, and this is true for all the quadratic functions of the form ax² + bx + c = 0.
Thus, in interval notation the domain of the function is (-∞, ∞).

Please help!!! The function d= 16t2 models the distance d, in feet, that an object falls in t seconds.
Find the inverse function and use the inverse function to estimate the time it takes an
object to fall 100 feet.
The inverse function is t = d/4
The time the object falls is 5 seconds.
The inverse function is t = d/16
The time the object falls is 0.625 seconds.
The inverse function is t = d/4
The time the object falls is 2.5 seconds.
The inverse function is t = d/16
The time the object falls is 6.67 seconds.

the sum of two and a number is less than five
Answer:
Please check the explanation.
Step-by-step explanation:
Given the English statement
''The sum of two and number is less than five''.
Let us breakdown the statement.
Let 'n' be the number. The sum of two and number = 2 + nWe know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
2 + n < 5Let us solve the algebraic expression.
[tex]2+n<5[/tex]
Subtract 2 from both sides
[tex]2+n-2<5-2[/tex]
Simplify
[tex]n<3[/tex]
Thus, the solution is:
[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

solve for x and b
Answer:
2x + 60 = 4x( Vertically opposite angle)
60 = 4x - 2x
4x - 2x = 60
2x = 60
x = 60÷2
x = 30
2x + 60 + B = 180° ( Linear Pair )
2(30) + 60 + B = 180°
60 + 60 + B = 180°
120 + B = 180°
B = 180° - 120
B = 60
