Answer: 20%
Step-by-step explanation:
We have to find out how many prime numbers there are from 20 to 30.
There are only 23 and 29. We have to make a fraction out of 2 over 10.
The fraction can be: [tex]\frac{2}{10}[/tex]
[tex]\frac{2}{10}[/tex] can be written as a percent as 20%.
The answer is 20%

Which of the following regular polygons circumscribed about a circle provides the best estimate for the area of that circle?
dodecagon
decagon
20-gon
11-gon
Answer:
The correct option is;
20-gon
Step-by-step explanation:
The area, A, of a regular polygon is given as follows;
[tex]A = \dfrac{n \times s \times a}{2} = \dfrac{P_p \times a}{2}[/tex]
Where;
n = The number of sides
s = The length of one side of the polygon
a = The apothem
[tex]P_p[/tex] = The perimeter of the polygon
Where
The area of a circle, A[tex]_c[/tex] = π×r² = π × r × r = 2× π × r × r/2 = P/2 × r
Given that the apothem, a, of a 20-gon circumscribed about a circle is approximately the length of the radius of the circle, and the perimeter of the 20-gon is approximately the perimeter (circumference) of the circle, the area of the 20-gon circumscribed about a circle provides the best estimate for the area of the circle.

im confused any help?
Answer:
60 points
Step-by-step explanation:
Every time he earns points we add.
Every time he loses points we subtract.
We can write an equation to resemble the problem and simplify.

8. What is the result of (11x + 18i)(117 - 18i)?
Please help with these angles!!!
Answer:
23. y = 47
Step-by-step explanation:
40 + 5x =180 (angls on a straight line add up to 180 degrees)
5x=140 (minus 40 from both sides)
x = 28 (divide both sides by 5)
3y - 1 = 140
3y =141 (add 1 to both sides)
y = 47 (divide both sides by 3)
Answer:
y=47

Step-by-step explanation:
If p represents doubling the dimensions of a rectangle and q represents the area increasing by a factor of 4, which are true? Select two options.
p → q represents the original conditional statement.
~p → ~q represents the inverse of the original conditional statement.
q → p represents the original conditional statement.
~q → ~p represents the converse of the original conditional statement.
p → ~q represents the contrapositive of the original conditional statement.
Answer:
p → q represents the original conditional statement.
Step-by-step explanation:
In the case when p represents the dimensions that is double of a rectangle while on the other hand the q represent the area i.e. increased by a factor of 4
So this both shows the conditional statement i..e real
where,
P termed as hypothesis
And, q termed as a conclusion
Therefore
The first option is correct

On which interval is y = sin(x) strictly increasing?
(Negative pi, negative StartFraction pi Over 2 EndFraction)
(0, pi)
(StartFraction pi Over 2 EndFraction, StartFraction 3 pi Over 2 EndFraction)
(0, StartFraction pi Over 2 EndFraction)
Answer:
The function is strictly increasing on (0, π/2)
Step-by-step explanation:
We are given the function;
y = sin x
Let's find the derivative;
dy/dx = cos x
Now, Cos 0 = 1
Cos (π/4) = 1/√2
Cos (π/2) = 0
From the above, we can see that as x approaches 0 from (π/2), the value of (cos x) approaches 1. This means it's increasing from 0 to 1.
Thus, the function is strictly increasing on the interval (0, π/2)
Answer:
D. (0, pi/2)
Step-by-step explanation:
If you graph y=sin(X) (I used desmos) then you find that the graph is increasing from 0 to pi/2 :)

Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change. If Tristan used a coupon for 25% off, what was the original price for one ticket?
Answer:
$36
Step-by-step explanation:
Tristan paid $50 for the tickets of the school play and was given $23 as change. The amount Tristan paid for the ticket is given as:
Price for ticket = amount paid - change = $50 - $23 = $27
Price for ticket = $27
Given that the ticket was sold at 25% off. Let x be the original price of the ticket, therefore:
x - 25% of x = $27
x - 0.25x = 27
0.75x = 27
x = 27/ 0.75
x = 36
Therefore the original price of the ticket is $36
Answer:
27.00

If f(x) = 0.41x is a function that represents the cost to mail
x number of letters, what is a reasonable domain for f?
O all real numbers
o all real numbers greater than 0
O the set of all whole numbers
o the set of all integers
Answer:
B
Step-by-step explanation:
The domain of the function 'f' represents the set of all whole numbers.
What is a function?A function is a relation between two sets. One set is called domain of the function and the other one is called range range of the function.
Given function is: f(x) = 0.41x.
f(x) represents the cost of mail.
Here, x represents the number of letters in the mail.
It can't be real numbers because, real numbers consist of negative numbers, fractions, etc.
It can not be integers, real numbers consist of negative numbers.
Therefore, the domain of must be all whole numbers.
