if a circle is centered at the vertex of the angle, then the arc subtended by the angle's rays is times as long as 1/360th of the circumference of the circle. a circle is centered at the vertex of the angle, and 1/360th of the circumference is 0.03 cm long. what is the length of the arc subtended by the angle's rays?
Answers
To find the length of the arc subtended by the angle's rays, we'll use the information given: the circle is centered at the vertex of the angle, and 1/360th of the circumference is 0.03 cm long.
Step 1: Calculate the full circumference.
Since 1/360th of the circumference is 0.03 cm, we can find the full circumference by multiplying 0.03 cm by 360.
Circumference = 0.03 cm * 360 = 10.8 cm
Step 2: Determine the angle subtended by the arc.
In this case, we don't have the specific angle mentioned, so let's assume the angle is θ degrees.
Step 3: Calculate the length of the arc subtended by the angle's rays.
To find the length of the arc, we will use the formula:
Arc length = (θ/360) * Circumference
Since we don't have the exact value for θ, the answer will be in terms of θ:
Arc length = (θ/360) * 10.8 cm

To find the square root of a fraction, find the square root of the numerator and denominator individually
So, √9 = 3
√49 = 7
Put them back as a fraction = 3/7
Hope this helps
Please mark brainiest
Answer:
3/7
Step-by-step explanation:
We want to find the square root of 9/49.
Remember that when we take the square root of a fraction, it's equal to taking the square root of each of the numerator and denominator.
Let's split this up into the numerator and denominator:
Numerator:
The numerator is 9, and we know that the square root of 9 is 3. This is because 3 * 3 = 9.
Denominator:
The denominator is 49, and we know the square root of 49 is 7 because 7 * 7 = 49.
Thus, we have:
\(\sqrt{\frac{9}{49} } =\frac{\sqrt{9} }{\sqrt{49} } =3/7\)
The answer is hence 3/7.

At Mathville Middle School, there were 50 students and 50 lockers. Each year for Pi Day (March 14), the students lined up in alphabetical order and performed the following strange ritual. The first student opened every locker. The second student went to every second locker and closed it. The third student went to every third locker and changed it (i.e. if the locker was open, the student closed it; if the locker was closed, the student opened it). In a similar manner, the fourth, fifth, sixth, . . . student changed every fourth, fifth, sixth, . . . locker. After all 50 students had passed by the lockers, which lockers were left open?
PLZZZZ help me T^T
Answers
Step-by-step explanation:
This problem is a bit tedious to work out all at once. The first student opens every locker so lockers 1 to 50 are open.
The second student closes every two lockers so every even locker is closed while every odd locker is open. This will repeat over and over and will take too long.
An alternative for this would be checking the factors of each number. For example, 4 has three unique factors, which are 1, 2 and 4. The number of unique factors determine whether the locker is open or closed. In this case, locker 4 will be open after all 50 students finished. Student 1 opens locker 4, student 2 closes locker 4, student 3 doesn't change locker 4 and student 4 opens locker 4. However, students 5 to 50 will never change the locker.

Answers
163.79 students were surveyed.
The survey asked randomly selected students whether they preferred vanilla ice cream or chocolate ice cream. 58% of the students said they preferred vanilla ice cream, with a 5% margin of error. To calculate the total number of students surveyed, we can use the following formula:
Number of Students Surveyed = (100 - Margin of Error) ÷ (Percentage that Prefer Vanilla/100)
In this case, we get:
Number of Students Surveyed = (100 - 5) ÷ (58/100)
Number of Students Surveyed = 95 ÷ 0.58
Number of Students Surveyed = 163.79
Therefore, 163.79 students were surveyed.

Tell how many roots of the following polynomial are in the right half-plane, in the left half-plane, and on the jω-axis: [Section: 6.3] P(s) = s^5 + 6s^3 + 5s^2 + 8s + 20
Answers
To determine the number of roots of P(s) in the right half-plane, left half-plane, and on the jω-axis, we can use the Routh-Hurwitz stability criterion.
First, we construct the Routh array:
| 1 | 5 | 8 |
| 6 | 5 | 0 |
| -5.6 | 8 |
The first column of the Routh array has all positive elements, indicating that all the roots of the polynomial have positive real parts or are located on the jω-axis. However, the second column has one negative element, indicating that there is one root in the left half-plane.
To determine the number of roots on the jω-axis, we look for the number of sign changes in the first column of the Routh array. In this case, there is one sign change, indicating that there is one root on the jω-axis.
Therefore, the number of roots in the right half-plane is 0, the number of roots in the left half-plane is 1, and the number of roots on the jω-axis is 1.
The Routh array is a tabular method used in control engineering to determine the stability of a linear time-invariant system. It was introduced by Edward John Routh in the 19th century and is a valuable tool in analyzing the roots of a polynomial equation.
To construct a Routh array, the coefficients of the polynomial equation are arranged in a table, starting from the highest order term down to the constant term. The first two rows of the table are then calculated using the coefficients in the polynomial equation as follows:
The first row consists of the coefficients of the even powers of the polynomial.The second row consists of the coefficients of the odd powers of the polynomial.Visit here to learn more about Routh array brainly.com/question/31318894

What are comparison in math?The process of comparison reveals the shared characteristics of several objects. This is the fundamental idea in mathematics that guides our descriptions of whether two numbers are equal, one is more than, one is less than, or both are equal. Comparing fractions, decimals, and rational numbers are all possible.
The coordinates of the point are:
J (2, 4)
K (7, 8)
L (1, -1)
The distance between two points is given by the formula:
D = √(x2 - x1)² + (y2 - y1)²
The distance between JK is:
JK = √(7 - 2)² + (8 - 4)
JK = √25 + 16 = √41 = 6.40
The distance between JL is:
JL = √(1 - 2)² + (-1 - 4)²
JL = √1 + 25 = √26 = 5.09
Hence, the statement about JK and JL is, JK is longer than JL.

The complete question is:
the scores on a standardized test are normally distributed with μ=1000 and σ = 250. what score would be necessary to score at the 85th percentile?
Answers
we first need to understand what the term percentile means in the context of a standardized test. A percentile is a statistical measure that indicates the percentage of scores that fall below a particular score.
For example, if a student scores in the 85th percentile on a standardized test, it means that their score is higher than 85% of the scores of all the students who took the test.
Given that the scores on a standardized test are normally distributed with a mean (μ) of 1000 and a standard deviation (σ) of 250, we can use the normal distribution formula to find the score necessary to score at the 85th percentile.
The first step is to convert the percentile to a z-score using the z-score formula:
z = (x - μ) / σ
where x is the score we want to find, μ is the mean, and σ is the standard deviation.
To find the z-score for the 85th percentile, we need to find the z-score that corresponds to the area of 0.85 under the standard normal distribution curve. We can look up this value in a standard normal distribution table or use a calculator to get z = 1.04.
Now we can use the z-score formula to solve for x:
1.04 = (x - 1000) / 250
Solving for x, we get:
x = 1.04 * 250 + 1000 = 1260
Therefore, a score of 1260 would be necessary to score at the 85th percentile on this standardized test.

Answers
According to the problem, Han and Clare are stuffing envelopes. He can stuff 20 envelopes in one minute and Clare can stuff 10 envelopes in one minute. This means that they can jointly stuff 30 envelopes in one minute.
Now, mathematically we know that the number of time it will take to finish stuffing would be:
\(\frac{number\text{ of envelopes}}{joint\text{ rate}}\text{ =}\frac{1000\text{ envelopes}}{30\text{ envelopes per minute}}\)If we simplify this expression, we get:
\(\frac{100\text{ envelopes}}{3\text{ envelopes per minute}}\)this can be written as:
\(33\text{ + }\frac{1}{3}\text{ minutes}\)this is true since:
\(33\text{ + }\frac{1}{3}=\frac{33(3)\text{ + 1}}{3}=\frac{99\text{ + 1}}{3}=\frac{100}{3}\text{ minutes}\)thus, we obtain that it will take them 33 minutes and 20 seconds
Then, we can conclude that the correct answer is:

You go to the doctor and he gives you 14 milligrams of radioactive dye. After 16 minutes, 5.25 milligrams of dye remain in your system. To leave the doctor's office, you must pass through a radiation detector without sounding the alarm. If the detector will sound the alarm if more than 2 milligrams of the dye are in your system, how long will your visit to the doctor take, assuming you were given the dye as soon as you arrived
Answers
Answer:
31.7 min
Step-by-step explanation:
Given that;
N(t) = Noe^kt
No = amount of radioactive isotope initially present
N(t) = amount of radioactive isotope present at time t
t = time taken
k = decay constant
5.25 = 14e^-k16
5.25/14 = e^-k16
0.375 = e^=k16
ln(0.375) = =-16k
k = ln(0.375)/-16
k = 0.0613 min^-1
So time taken for 2 mg to remain;
2 = 14e^-0.0613t
2/14 = e^-0.0613t
0.1429 = e^-0.0613t
ln(0.1429) = -0.0613t
t = ln(0.1429)/-0.0613
t = 31.7 min
A farmer is going to divide her 40 acre farm between two crops. Seed for crop A costs $15 per acre. Seed for crop B costs $30 per acre. The farmer can spend at most $900 on seed. If crop B brings in a profit of $50 per acre, and crop A brings in a profit of $110 per acre, how many acres of each crop should the farmer plant to maximize her profit? acres of crop A acres of crop B
Answers
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of acre on which crop A is farmed and B represent the number of acre crop B is farmed.
Therefore:
Since there is a total of 40 acre farm, hence:
x + y = 40 (1)
The farmer can spend at most $900 on seed, crop A seed cost $15 and crop B seed cost $50, hence:
15x + 50y ≤ 900 (2)
Her profit is given as:
Profit = 50x + 110y
From the geogebra plot, the point that maximizes the profit is at (60, 0)
Therefore the maximum profit = 50(60) + 110(0) = $3000
