The arc length of the sector is 10π inches, and the area of the sector is 60π square inches.

What is the arc length and area of the sector of a circle?

Arc length = [tex] \frac{ \theta}{ {360}^{o} } \times 2\pi \: r[/tex]

Area of sector = [tex] \frac{ \theta}{ {360}^{o} } \times \pi \: {r}^{2} [/tex]

Where r is the radius of the circle, angle is the central angle in degrees, and π is the mathematical constant pi (approximately equal to 3.14159).

Given that the angle is 150° and the radius is 12 inches, we can substitute these values into the formulas to get:

Arc length

[tex]= \frac{150}{360} \times 2π(12) \\ = \frac{5}{12} \times 2π(12) \\ = 10π \: inches[/tex]

Area of sector

[tex]= \frac{150}{360} \times π(12)^2 \\ = \frac{5}{12} \times π(144) \\ = 60π \: square \: inches[/tex]

Therefore, the arc length of the sector is 10π inches, and the area of the sector is 60π square inches.

Answer:

  cos(L) = (√46)/11

Step-by-step explanation:

You want cos(L) in simplest terms, given right triangle side lengths LK=√46 and JK=√75.

The cosine is the ratio ...

  Cos = Adjacent/Hypotenuse

The side adjacent to vertex L is LK. The hypotenuse of the triangle is LJ. This means the desired ratio is ...

  cos(L) = LK/LJ

The length of hypotenuse LJ can be found using the Pythagorean theorem.

  LJ² = LK² +JK²

  LJ² = (√46)² +(√75)² = 46 +75 = 121

  LJ = √121 = 11

Then the desired ratio is ...

  cos(L) = (√46)/11

The brace must be approximately 38.1 cm long.

To find the length of the brace for the closet rod holder,

we can use the Pythagorean theorem,

which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the vertical side is 15 cm and the horizontal side is 35 cm.

Let's call the length of the brace (the hypotenuse) "c".

According to the Pythagorean theorem:
[tex]c^2 = (15 cm)^2 + (35 cm)^2[/tex]
[tex]c^2 = 225 cm^2 + 1225 cm^2[/tex]
[tex]c^2 = 1450 cm^2[/tex]
Now, to find the length of the brace, we need to take the square root of both sides:
[tex]c = \sqrt{(1450 cm^2)}[/tex]
c ≈ 38.1 cm.

The solutions for y are:

We can simplify the expression sqrt(160) by factoring 160 into its prime factors:

160 = 2^5 * 5

Taking the square root of each factor, we get:

sqrt(160) = sqrt(2^5 * 5) = sqrt(2^4 * 2 * 5) = 2^2 * sqrt(2 * 5) = 4 * sqrt(10)

Therefore, we can simplify the expression for y as follows:

y = (7 +- sqrt(160))/10 = (7 +- 4sqrt(10))/10

So the solutions for y are:

y = (7 + 4sqrt(10))/10

y = (7 - 4sqrt(10))/10

Therefore, the probability that a student who did not complete the homework passed the test is 2/5 or 0.4 (or 40%).

Probability is a measure of the likelihood of an event occurring. It is a numerical value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To calculate the probability of an event, we divide the number of favorable outcomes by the total number of possible outcomes. For example, if we toss a fair coin, the probability of getting heads is 1/2 because there is one favorable outcome (getting heads) out of two possible outcomes (getting heads or tails).

Let's define the following events:

A: passing the test

B: completing the assignment

We know that:

[tex]P(A) = 18/28 = 9/14[/tex] (since 18 students out of 28 passed the test)

[tex]P(B) = 19/28[/tex] (since 19 students out of 28 completed the assignment)

P (A ∩ B) = P(B) = 19/28 (since every student who completed the assignment also took the test)

We want to find P (A | not B), which represents the probability of passing the test given that the student did not complete the assignment.

Using Bayes' theorem, we have:

P (A | not B) = P (not B | A) * P (A) / P (not B)

We know that:

P (not B | A) = P (A' ∩ B') / P(A') = 7/28 / 10/28 = 7/10 (since 7 students failed the test and did not complete the assignment)

P (not B) = 1 - P(B) = 9/28 (since not completing the assignment is the complement of completing the assignment)

Plugging in these values, we get:

[tex]P(A | not B) = (7/10) * (9/14) / (9/28)[/tex]

[tex]P(A | not B) = 2/5[/tex]

Answer:

y in (7,y) = 14

Step-by-step explanation:

A General Linear function is as the following:

y = mx + c, Where: m: slope of the line, c: y-intercept

Given that:

Point 1 (P1) = (1,5)

Point 2 (P2) = (3, 11)

Point 3 (P3) = (7,y)

By substituting in the linear function with P1:

5 = m + c  ---> (1)

By substituting in the linear function with P2:

11 = 3m + c   ---> (2)

By multiplying equation (1) times 3 and subtracting eq. (2) from it:

(15 = 3m + 3c) - (11 = 3m + c) =

4 = 2c

Then, c = 2

By substituting with "c" in eq. (1):

5 = m + 2

Then, m = 3

Hence,

the function of this line is:

y = 3x + 2

So,

to get "y" in P3, we are going to substitute with 7:

y = 3(7) + 2

then "y" in P3 = 23


Another Solution:

by getting the slope of the line:

[tex]Slope = \frac{\triangle y}{\triangle x}[/tex] Where: Δy: change in y points, Δx: change in x points

by utilizing P1 & P2 in slope formula:

[tex]slope = \frac{11 - 5}{3 - 1} = \frac{6}{2} = 3[/tex]

By substituting with P1 in the linear function:

5 = 3 + c

Then, c = 2

the function of the line is:

y = 3x + 2

So,

to get "y" in P3, we are going to substitute with 7:

y = 3(7) + 2

then "y" in P3 = 23

According to the given question, the center of the circle is (-9, 46) and its radius is approximately 11.09.

The equation of a circle is a formula that describes the relationship between the x and y coordinates of any point on the circle.

The standard equation of circle is:

(x - h)²+(y - k)²=r²

This equation states that the sum of the squares of the differences between the x-coordinate and the center, and the y-coordinate and the center, is equal to the square of the radius.

The equation of the circle is given by (x+9)² + (y-46)² = 123.

Comparing this to the standard equation of a circle, (x-h)² + (y-k)² = r², we can see that the center of the circle is (-9, 46) and the radius is √(123) = 11.09.

What is Algebraic expression ?

An algebraic expression is a mathematical phrase that can contain variables, constants, and operators (such as addition, subtraction, multiplication, and division) that are used to represent quantities and their relationships.

To solve the system using addition, we want to add the two equations together in a way that eliminates one of the variables. In this case, we can add the two equations directly because the x term will cancel out:

X - 4.7y = -9.1

+(-x + 5.8 = 12.4)

1.1y = 3.3

Now we can solve for y by dividing both sides by 1.1:

y = 3.3 ÷ 1.1

y = 3

Substituting y = 3 back into one of the original equations, we can solve for x:

x - 4.7y = -9.1

x - 4.7(3) = -9.1

x - 14.1 = -9.1

x = 5

Therefore, the solution to the system of equations is x = 5 and y = 3.

What is system of linear equations?

The collection of two or more linear equations is called as system of linear equations. The linear equations have the degree of variable as one. Though a single linear equation can have infinite number of solutions, but a pair of linear equation can be classified as consistent or inconsistent. The equations which are consistent have either one solution or infinte solutions. The intersecting pair of consistent equations have unique solution whereas the coinciding pair of consistent equations have infinite number of solutions. The equations which are inconsistent are the parallel lines which do not have any solution.

The estimated amount Franklin will pay in finance charges on his $1,520 purchase is $35.07.

What is annual percentage rate?

Annual Percentage Rate (APR) is the annual rate charged for borrowing or earned through an investment and is expressed as a percentage that represents the actual yearly cost of funds over the term of a loan or investment.

The finance charges on a credit card purchase can be calculated using the following formula:

finance charges = (APR/365) * balance * number of days

Where APR is the annual percentage rate, balance is the amount of the purchase, and the number of days is the time period for which the finance charges are being calculated.

Assuming that Franklin does not make any payments towards his credit card balance during the billing period, the number of days for which finance charges will be calculated will be equal to the billing cycle. Let's assume a billing cycle of 30 days for this example.

Using the formula above, we can calculate the finance charges as follows:

finance charges = (28.2%/365) * $1,520 * 30

= (0.00077397) * $1,520 * 30

= $35.07 (rounded to the nearest cent)

Answer:

The area of the path running around the square field is 475 square meters.

To find the area of the path running around a square field with a side of 45 meters and a path width of 2.5 meters,

Calculate the area of the entire square (including the path):

Side of the larger square = 45 M (side of the field) + 2.5 M (width of the path on one side) + 2.5 M (width of the path on the opposite side) = 50 M

Area of the larger square = (Side of the larger square)²

                                          = (50 M)²

                                          = 2500 M²

Calculate the area of the square field (without the path):

Side of the field = 45 M

Area of the square field = (Side of the field)²

                                       = (45 M)²

                                       = 2025 M²

Subtract the area of the square field from the area of the entire square to find the area of the path:

Area of the path = Area of the larger square - Area of the square field

                           = 2500 M² - 2025 M²

                           = 475 M²

So, the area of the path running around the square field is 475 square meters.
