Answer:

∠BAD=20°20'

∠ADB=34°90'

Step-by-step explanation:

AB is tangent to the circle k(O), then AB⊥BO. If the measure of arc BD is 110°20', then central angle ∠BOD=110°20'.

Consider isosceles triangle BOD (BO=OD=radius of the circle). Angles adjacent to the base BD are equal, so ∠DBO=∠BDO. The sum of all triangle's angles is 180°, thus

∠BOD+∠BDO+∠DBO=180°

∠BDO+∠DBO=180°-110°20'=69°80'

∠BDO=∠DBO=34°90'

So ∠ADB=34°90'

Angles BOD and BOA are supplementary (add up to 180°), so

∠BOA=180°-110°20'=69°80'

In right triangle ABO,

∠ABO+∠BOA+∠OAB=180°

90°+69°80'+∠OAB=180°

∠OAB=180°-90°-69°80'

∠OAB=20°20'

So, ∠BAD=20°20'

Answer:

The measure of ∠BAD and ∠ADB is 20°20' and 34°90' respectively.

Step-by-step explanation:

Given that AB is tangent to the circle k(O) at B, and AD is a secant, which goes through center O. Point O is between A and D∈k(O).

measure of arc BD is 110°20'.

we have to find the measure of ∠BAD and ∠ADB

∠4=110°22'

In ΔOBD, by angle sum property of triangle

∠1+∠2+∠4=180°

∠1+∠2+110°20'=180°

∠1+∠2=69°80'

Since OB=OD(both radii of same circle) therefore ∠1=∠2

[tex]2\angle 2=69^{\circ}80'[/tex]

[tex]\angle 2=\frac{69^{\circ}80'}{2}=34^{\circ}90'[/tex]

m∠ADB=34°90'

As OB is radius of circle and AB is tangent therefore by theorem which states that radius is perpendicular on the tangent line gives

[tex]\angle 6=90^{\circ}[/tex]

By exterior angle property

∠5=∠1+∠2=69°80'

By angle sum property in ΔABO

∠3+∠6+∠5=180°

∠3+90°+69°80'=180°

∠3=20°20'

Answer:3100 with 9%

Step-by-step explanation:

Answer:

The answer is $3,100 at 9%; $4,900 at 11%

Step-by-step explanation:

You can solve this problem with a system of equations, that is, a system that can contain 2 or more equations. In this case, arms 2 linear equations with two variables: x and y. So first you define what your variables are:

Now you can define the system of equations. On the one hand you know that in the account that has 11% interest Mr. Brownwood deposited $1800 more than in the other account. In an equation and according to the previously defined variables this means: y=x+1800 Equation (A)

On the other hand, you know Mr. Brownwood earned $ 818 in interest. This means that the sum between the interest generated in the account deposited with 9% interest plus the interest generated in the account deposited with 11% interest is $ 818. And to calculate the amount of money generated by interest you multiply the percentage of interest by the amount deposited.  Remember that to convert from percentage to decimal you must divide the number by 100. Then 9% is 0.09 and 11% is 0.11. In summary, considering this, you get the equation: 0.09*x+0.11*y=818 Equation (B)

Now you have both equations with the two variables to solve the system. There are several ways to solve the system. One of the most used ways is substitution, which consists in isolating one of the variables from one of the equations and replacing it in the other equation.

In this case you isolate the variable "y" from equation A, and you get:  y=1800+x

Now replace it in equation (B): 0.09*x+0.11*(1800+x)=818

First you apply distributive property, which consists of distributing the multiplication by the terms within the parenthesis:

0.09*x+0.11*1800+0.11*x=818

0.09*x+198+0.11*x=818

Now, we leave the variable x on one side of the equality, in this case the left, and the numbers without the variable on the other side, in this case the right. To pass the numbers from one side of the equality to the other, you must keep in mind that you must use the opposite operation, that is, if the number 198 is adding on one side of the equality, the other side is subtracted:

0.09*x+0.11*x=818-198

Now you perform the corresponding operations. Then you isolate the variable and, and as in the previous case, you pass the number that accompanies the variable on the other side of equality with the opposite operation. In this case it is multiplying and its opposite operation is the division:

0.2*x=620

[tex]x=\frac{620}{0.2}[/tex]

x=3100

Now you replace this value in either of the two equations, A or B, and solve that equation to get the value of y. So: y=4900

Remembering that x was amount of money invested in the account with 9% interest and y was amount of money invested in the account with 11% interest, you can say that $3100 was the amount invested at 9% and $4900 was the amount invested at 11%

Answer:

The correct answer is option C.

Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1

Step-by-step explanation:

The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.

The table is easily available on the internet.

WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.

The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.

So

Sin 45 = √2/2

Cos 45 = √2/2

and

Tan 45 = 1

So the correct option is C.

The sine, cosine, and tangent of 45 degrees can be found using the values of the adjacent side, opposite side, and hypotenuse of a right triangle. The sine of 45 degrees is (√2) / 2, the cosine is (√2) / 2, and the tangent is 1.

The sine, cosine, and tangent of 45 degrees can be found using the values of the adjacent side, opposite side, and hypotenuse of a right triangle. In this case, for a 45-degree angle, the adjacent side and opposite side are equal, so we can use the Pythagorean theorem to find the value of the hypotenuse. Let's denote the length of the adjacent and opposite sides as x.

Sine (sin) 45 degrees: sin 45 degrees = opposite side / hypotenuse = x / √2x = 1 / √2 = (√2) / 2

Cosine (cos) 45 degrees: cos 45 degrees = adjacent side / hypotenuse = x / √2x = 1 / √2 = (√2) / 2

Tangent (tan) 45 degrees: tan 45 degrees = opposite side / adjacent side = x / x = 1

Answer:

The location of point K is (1 , 2)

The location of point L is (7 , 0)

Step-by-step explanation:

* Lets revise how to find the location of a point between two points

- If point (x , y) is between two points (x1 , y1) , (x2 , y2) at a ratio

 m1 from (x1 , y1) and m2 from (x2 , y2)

∴ x = [x1(m2) + x2(m1)]/(m1 + m2)

∴ y = [y1(m2) + y2(m1)]/(m1 + m2)

* Now lets solve the problem

- Point J is (-5 , 4) and point M is (10 , -1)

∵ Point K is 2/5 of JM

∴ m1 = 2 ⇒ ratio from K to J

∴ m2 = 5 - 2 = 3 ⇒ ratio from K to M

∴ x = [(-5)(3) + (10)(2)]/(2 + 3) = [-15 + 20]/5 = 5/5 = 1

∴ y = [(4)(3) + (-1)(2)]/(2 + 3) = [12 + -2]/5 = 10/5 = 2

* The location of point K is (1 , 2)

∵ Point L is 4/5 of JM

∴ m1 = 4 ⇒ ratio from K to J

∴ m2 = 5 - 4 = 1 ⇒ ratio from K to M

∴ x = [(-5)(1) + (10)(4)]/(2 + 3) = [-5 + 40]/5 = 35/5 = 7

∴ y = [(4)(1) + (-1)(4)]/(2 + 3) = [4 + -4]/5 = 0/5 = 0

* The location of point L is (7 , 0)

Eve should knit between 3 and 6 scarves per day in the next 2 days to meet her goal, with a minimum total of 15 and a maximum of 21 scarves for the week.

Eve has already knitted 9 scarves and wants to knit at least 15 scarves and at most 21 scarves by the end of the week. With 2 days left in her work week, we need to calculate how many more scarves she should knit each day to achieve her goal.

First, let's calculate the minimum number of scarves she needs to knit to meet her goal of 15 scarves. She needs to knit 15 - 9 = 6 more scarves. Dividing 6 scarves by 2 days, we find she needs to knit a minimum of 3 scarves per day.

Now, let's calculate the maximum number of scarves to meet her goal of 21 scarves. She needs to knit 21 - 9 = 12 more scarves. Dividing 12 scarves by 2 days, we find she needs to knit a maximum of 6 scarves per day.

Therefore, to meet her goal for the week, Eve should knit between 3 and 6 scarves per day for the remaining two days.

Eve should knit between 3 and 6 scarves per day in the next two days to meet her goal.

To determine the number of scarves Eve should knit each day, we need to find how many more scarves she needs to meet her goal and then spread that number evenly over the 2 remaining days. Eve has made 9 scarves already.

The maximum and minimum scarves can be calculated as below:

Minimum scarves needed [tex]= 15 - 9 = 6[/tex]

Maximum scarves needed [tex]= 21 - 9 = 12[/tex]

Now the remaining scarves need to be completed in 2 days. So, it find number of remaining scarves to be completed per day we divide the maximum and minimum value by 2 as follows:

Minimum scarves per day [tex]= \frac{6}{2} = 3[/tex]

Maximum scarves per day [tex]= \frac{12}{2} = 6[/tex]

Therefore, Eve should knit between 3 and 6 scarves per day in the next two days to meet her goal.

Answer:

10.92 m

Step-by-step explanation:

  To solve for the height, we first find the area of the triangle. Since the area of a triangle is 1/2 of the base times the height, we get the area to be 109.2. Dividing it by 20 and then multiplying by 2, we get 10.92 as the height.

To find the angle ∠KL, knowing m∠KJL = 27°, it is essential to apply the properties of tangents and circles.

The angle ∠KJL can be determined using the properties of tangents and circles. Since JK is a tangent to circle C, we know that angle ∠KJL is equal to half of the intercepted arc KL. Therefore, if m∠KJL = 27°, then m∠KL = 2 × 27° = 54°.

Formula

Area of Hexagon = 3*sqrt(3)*a^2 / 2

Area of a Square = a^2

In both cases a is a side length

Givens

A = 384*sqrt(3)

Solution

384*sqrt(3) = 3*sqrt(3)*a^2 / 2     Divide by sqrt(3) on both sides.

384 = 3 * a^2 / 2                           Multiply by 2

768 = 3 * a^2                                Divide by 3

256 = a^2                                     Take the square root of both sides

a = 16

Each side of the square will be = a

The area of the square = a^2

The tangents meet the circumference of the circle at a 90o angle when the radius is connected by the point of  contact. Call the central angle (LON) = x

The two tangents and the two radii form a kite which is a quadrilateral.

All quadrilaterals have 4 angles that add up to 360.

x + 90 + 90 + 60 = 360           Combine the like terms on the left

x + 240 = 360                           Subtract 240 from both sides

x = 360 - 240

x = 120

The length of the arc is given by (Central angle / 360) * Circumference

x is the central angle so the central angle = 120

Length = (120 / 360) * 96

Length = 1/3 * 96

Length = 32

Answer:

The true properties are:

A.) The circumcenter of a right triangle falls on the side opposite the right angle

B.) The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides

D.) The circumcenter is equidistant from each vertex of a triangle - The circumcenter of a triangle is the point which is equidistant from the three vertices of the triangle.

The false property is :

C.) The circumcenter of a triangle is always inside it - The circumcenter is not always inside the triangle. Its a point where all three lines intersect and its not necessary that it lies within the triangle.

Final answer:

The circumcenter is defined as the point where the perpendicular bisectors of a triangle's sides intersect and is equidistant from each vertex, which applies to all types of triangles. However, it lies on the hypotenuse for right triangles and can be outside the triangle for obtuse ones.

Explanation:

The properties of the circumcenter of a triangle are a critical concept in geometry. Here's how each option relates to this concept:

B.) The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides. This is a defining property of the circumcenter and is always true regardless of the type of the triangle.

D.) The circumcenter is equidistant from each vertex of a triangle. By definition, the circumcenter is the point from where you can draw a circle (circumcircle) that encompasses all three vertices of the triangle at equal distances.

Now for the other options that are not always true:

A.) The circumcenter of a right triangle falls on the side opposite the right angle. This is true specifically for right triangles, but it's not a general property of the circumcenter for all types of triangles.

C.) The circumcenter of a triangle is always inside it. This is not true. For obtuse triangles, the circumcenter lies outside the triangle, while for acute triangles it is inside, and for right triangles, it is on the triangle.

Answer:

C

Step-by-step explanation:

We can multiply each equation by a constant so they'll equal either 15 or -15 since that is the LCM.

Since the answer choices want us to make the top a negative 15, we'll do that.

[tex]2x-5y=-21 \\ \\ 3(2x-5y)=(-21)*3 \\ \\ 6x-15y=-63[/tex]

To make the y's cancel out, the second equation would have to have the y's coefficient equal 15.

Let's do that.

[tex]3x-3y=-18 \\ \\ -5(3x-3y)=(-18)*-5 \\ \\ -15x+15y=90[/tex]

So the resulting equations are answer choice C.

Answer:

  D.  f(q) = 2q + 3

Step-by-step explanation:

Choices B and C are eliminated right away because there is no "q" in the definition, just "s". If the function is to be a function of "q", then "q" is expected to appear in the definition.

__

The two variables in the given equation are "s" and "q". If "q" is designated as the independent variable, then the dependent variable is "s". The equation must be solved for "s":

  6q = 3s - 9

We observe that the coefficient of "s" is 3, and that all numbers are multiples of 3, so we can divide by 3 to simplify this a bit:

  2q = s - 3

Since we want an expression for s alone, we can add 3 to get ...

  2q +3 = s

Now, we can write ...

  s = f(q) = 2q +3

To find the perimeter of the dilated rectangle A'B'C'D', we need to know the dimensions of the original rectangle ABCD and the scale factor of the dilation. The perimeter of A'B'C'D' is equal to the sum of the lengths of all the sides in the dilated rectangle. Since AB = A'B' and BD = B'D', the perimeter can be simplified to AB + BC + CD + BD.

Explanation:

To find the perimeter of the dilated rectangle A'B'C'D', we need to know the dimensions of the original rectangle ABCD and the scale factor of the dilation.

If the scale factor is 3, it means that each side of the original rectangle will be multiplied by 3 to get the corresponding side of the dilated rectangle.

Since the rectangle ABCD is dilated with a center of dilation at vertex D, the length of side AB remains the same in the dilated rectangle A'B'.

To find the perimeter of A'B'C'D', we need to compute the lengths of all the sides in the dilated rectangle and sum them up.

Perimeter of A'B'C'D' = A'B' + B'C' + C'D' + D'A'

Since AB = A'B' and BD = B'D', the perimeter can be simplified to:

Perimeter of A'B'C'D' = AB + BC + CD + BD

The perimeter of rectangle A'B'C'D', which is a dilation of rectangle ABCD by a scale factor of 3 with center D, is three times larger than the original perimeter of ABCD.

If rectangle ABCD is dilated by a scale factor of 3 with a center of dilation at vertex D, to find the perimeter of A'B'C'D', we must first understand that a dilation scales all dimensions by the given factor. If the original lengths of the sides of rectangle ABCD are 'a' and 'b', with CD and AD being adjacent to vertex D, then after the dilation, the lengths of the corresponding sides would be '3a' and '3b'.

Since the perimeter of a rectangle is calculated by adding together the lengths of all its sides, the formula for the perimeter 'P' before dilation is P = 2a + 2b. After dilation, the new perimeter 'P' of A'B'C'D' will be P = 2(3a) + 2(3b) = 6a + 6b, which is simply three times the original perimeter. Therefore, the perimeter of rectangle A'B'C'D' after dilation is three times larger than the perimeter of the original rectangle ABCD.

To find the standard deviation for the number of defects per batch, use the formula for the standard deviation of a binomial distribution.

Explanation:

To find the standard deviation for the number of defects per batch, we need to use the formula for the standard deviation of a binomial distribution.

Given that the company manufactures televisions in batches of 25 and there is a 1% rate of defects, we can calculate the mean and variance of the number of defects per batch.

The mean (μ) of a binomial distribution is given by μ = np, where n is the number of trials (batch size) and p is the probability of success (defect rate). In this case, μ = 25 * 0.01 = 0.25. The variance (σ^2) of a binomial distribution is given by σ² = np(1-p). In this case, σ² = 25 * 0.01 * (1-0.01) = 0.2475.

The standard deviation (σ) is the square root of the variance, so σ ≈ √0.2475 ≈ 0.4975. Therefore, the standard deviation for the number of defects per batch is approximately 0.4975.

To calculate the standard deviation for the number of defects per batch with a 1% defect rate, use the formula for the standard deviation of a binomial distribution. The standard deviation is approximately 0.4975, indicating the variation in defects per batch.

The question you asked is about finding the standard deviation for the number of defects per batch in a manufacturing process where there is a 1% rate of defects.

To calculate the standard deviation for a binomial distribution, which is the case here since each television can be either defective or not, we use the formula: σ = √(np(1-p)), where σ is the standard deviation, n is the number of trials (or televisions), and p is the probability of success (or defect in this context).

Since each batch contains 25 televisions and the defect rate is 1% (0.01), we have:

n = 25
p = 0.01
1-p = 0.99

Plugging these values into the formula we get:

σ = √(25 * 0.01 * 0.99) = √(0.2475) ≈ 0.4975

Therefore, the standard deviation for the number of defects per batch is approximately 0.4975, which means – on average – you would expect the number of defects to vary around this value.

A bc the Y numbers increase by 17 every time X increases by 1

The common difference of the associated arithmetic sequence is:

          Option: A

                  17

We know that the sequence is said to be arithmetic if each of the sequence is differ by the preceding term by a fix constant which is known as a common difference.

i.e. d is called a common difference of the sequence if [tex]a_n\ and\ a_{n+1}[/tex]

are the nth and (n+1)th term of the sequence then,

[tex]a_{n+1}-a_n=d[/tex]

Here we have a  table of values as:

X     Y              d

1      4        

2    21        21-4=17

3    38       38-21=17  

4    55        55-38=17

5    72        72-55=17

Hence, we get that the common difference is: 17

Answer:

$25.11

Step-by-step explanation:

You have to divide 75.33 by the total number of shirts, 3, to see what one costs.

75.33/3=25.11

Answer:

each shirt will cost $25.11

Step-by-step explanation:

if each of the three friends gets a shirt and the total for all of them is $75.33, each shirt costs $25.11

75.33/3=25.11
