Twelve out of Sixty students are trying out for the spring musical. What is the percentage of students trying out for the musical?
If Twelve out of Sixty students are trying out for the spring musical, the percentage of students trying out for the musical is , 20%.
What are percentages?In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
Why are percentage representations important?The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
In above question, if Twelve out of Sixty students are trying out for the spring musical, we have,
Number of students trying out for the musical = 12
Total number of students = 60
Percentage of students trying out for the musical is , [tex]\frac{12}{60} *100[/tex] = 20%

Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in dollars for ordering 5 tickets is $108.00. Which linear function represents c, the total cost, when x tickets are ordered? (A service fee is a single fee applied to the total, no matter the number of tickets purchased).
Considering the definition of a line, the linear function that represents the total cost when x tickets are ordered is c= 20.5x + 5.50.
What is a linear equationA linear equation o line can be expressed in the form y = mx + b

x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Total cost in this caseIn this case, you know:
Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. This is, as service fee is a single fee applied to the total, no matter the number of tickets purchased, the value of "b" is 5.50.The total cost in dollars for ordering 5 tickets is $108.00Being Total cost= set price per ticket× amount of tickets + 5.50, then:
108=set price per ticket× 5 + 5.50
108 - 5.50= set price per ticket× 5
102.5= set price per ticket× 5
102.5÷5= set price per ticket
20.5= set price per ticket
Finally, the total cost is Total cost= 20.5× amount of tickets + 5.50.

SA = [ ? ]in2
The total surface area of the cone in terms of pi is 360π square inches
Total surface area of a cone is expressed as
TSA = πr(r+l)
Given that
radius = 10in
Height = 24in
Get the slant height 'l'.
l² = h²+r²
l² = 24²+10²
l² = 576+100
l² = 676
l = 26in
Substitute the given values into the formula
TSA = pi(10)(10+26)
TSA = pi(36)(10)
TSA = 360π in²
Hence the total surface area of the cone in terms of pi is 360π square inches

what is rectangle ?An example of a quadrilateral is a rectangle, which has four vertices that are all 90 degrees apart and parallel sides that are equal to one another. As a result, it is sometimes referred to as an equiangular quadrilateral. The rectangle is a 2D shape with 4 sides, 4 corners, and 4 right angles. The length of each pair of the diagonal sides of a rectangle is equal, with one pair being longer than the other. If all the sides of a rectangle were the same size, the shape would be referred to as a square.

The triangle flap of an envelope has two sides that are 6 centimeters long and meet at a right angle. How long is the envelope? Round to the 10ths if needed.
Answer:
Step-by-step explanation:
This is a right triangle that has two equal sides - so it is also isosceles.
It can be solved using Pythagoren Theorem.
a² + b² = c²
In this case a = b
so:
6² + 6² = c²
36 + 36 = c²
72 = c²
[tex]\sqrt{72[/tex] = [tex]\sqrt{c^{2} }[/tex]
8.49 = c

This is the length of the flap.
What is the range of the function with the graph given below ?
The graph in the question is a parabola that opens downwards.
What is function?A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions. These functions are called user-defined functions.
This means that the range of the function is all real numbers less than or equal to the y-intercept of the parabola, which is 0 in this case. Therefore, the range of the function is all real numbers less than or equal to 0.

Answer:
x = 30°y = 20°Step-by-step explanation:
The relevant relations are ...
the sum of the arcs of a circle is 360°an inscribed angle subtends an arc twice its measureThese give rise to two equations. (x and y are in degrees)
6y +6y +4x = 360
6y = 2(2x)
Substituting the latter into the former gives ...
6y +6y +6y = 360
y = 20 . . . . . . . . . . . . divide by 18
Then using this in the second equation, we have ...
6(20) = 4x
30 = x . . . . . . . . divide by 4

using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{x}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x = 6[tex]\sqrt{2}[/tex]

Step-by-step explanation:

From inspection of the given right triangle:
