An angle measures 3. 4° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer 1

Answer:

Let x be the measure of the angle we are trying to find, in degrees.

The complementary angle to x is 90° - x, since the sum of complementary angles is 90 degrees.

The problem tells us that x is 3.4 degrees less than its complementary angle, so we can set up the following equation:

x = (90 - x) - 3.4

Simplifying and solving for x, we get:

x = 86.6/2

x = 43.3

Therefore, the angle we are trying to find has a measure of 43.3 degrees, and its complementary angle has a measure of 90 - 43.3 = 46.7 degrees.

What is the smallest positive integer divisible by 6 and 2 you can write using at least one 2 and one 6?

Answers

The smallest positive integer divisible by 6 and 2 that can be written using at least one 2 and one 6 is 6.

The smallest positive integer that is divisible by both 2 and 6 is their least common multiple (LCM), which is equal to the product of the highest power of each prime factor that appears in the factorization of 2 and 6.

The prime factorization of 2 is simply 2, while the prime factorization of 6 is 2 × 3. The highest power of 2 that appears in the factorization of 6 is just 2 itself, so the LCM of 2 and 6 is 2 × 3 = 6.

We are asked to write this integer using at least one 2 and one 6. We can do this by simply writing 6, which is the LCM of 2 and 6 and is divisible by both of them. Since 6 contains one 2 and one 6, this meets the requirement of the problem. Therefore, the smallest positive integer divisible by 6 and 2 that can be written using at least one 2 and one 6 is 6.

The sum of first two angles is 120 degree and that of last two angles is 130 degree. Find all the angles in degrees.

Answers

The four angles are: A = 110 degrees, B = 10 degrees, C = 120 degrees,   D = 120 degrees

What are angles ?

Angles are geometric shapes created when two lines, rays, or line segments cross at a single point.

The two lines or line segments that make up the angle are referred to as the sides or arms of the angle, and this shared point is known as the vertex of the angle.

The amount of rotation required to shift one side to overlap with the opposite side determines the magnitude of an angle.

Angles are commonly expressed in degrees, with 360 degrees representing a full rotation around a point.

Acute angles (less than 90 degrees),

right angles (exactly 90 degrees),

obtuse angles (more than 90 degrees but less than 180 degrees), and straight angles (exactly 180 degrees) are some frequent forms of angles.

What are degrees ?

Angles are measured in degrees, a unit of measurement. 1/360th of a full revolution around a point is equivalent to one degree (1°).

Two perpendicular lines can be used to create a right angle, which has a 90 degree angle.

A straight angle, created by a straight line, has a degree value of 180.

Angles, rotations, and slopes are frequently measured in degrees in the fields of mathematics, physics, engineering, and several others.

The freezing point of water is 0 degrees Celsius (or 32 degrees Fahrenheit), whereas the boiling point is 100 degrees Celsius. In daily life, degrees are frequently used to express temperatures. (or 212 degrees Fahrenheit).

According to question :-

Let the four angles be A, B, C, and D. We know that:

A + B + C + D = 360 (the sum of all angles in a quadrilateral is 360 degrees)

We also know that:

A + B = 120 (the sum of the first two angles is 120 degrees)

C + D = 130 (the sum of the last two angles is 130 degrees)

We can use these equations to solve for the individual angles. First, we can rearrange the equation A + B = 120 to get:

A = 120 - B

Similarly, we can rearrange the equation C + D = 130 to get:

D = 130 - C

Substituting these expressions for A and D in terms of B and C into the equation A + B + C + D = 360, we get:

(120 - B) + B + C + (130 - C) = 360

Simplifying, we get:

250 - B + C = 360

Subtracting 250 from both sides, we get:

C - B = 110

Now we have two equations with two unknowns:

C + B = 130 (from the equation C + D = 130)

C - B = 110

We can add these equations to eliminate B and get:

2C = 240

Dividing by 2, we get:

C = 120

Substituting this value for C into either of the equations above, we get:

B = 10

Now we can use the equation A + B = 120 to find A:

A + 10 = 120

A = 110

Finally, we can use the equation A + B + C + D = 360 to find D:

110 + 10 + 120 + D = 360

D = 120

Therefore, the four angles are:

A = 110 degrees

B = 10 degrees

C = 120 degrees

D = 120 degrees

Find its price

Answers

a) The zero rates for the five maturities are: 1 year is 2.01%, 2 years is 2.48%, 3 years is 2.77%, 4 years is 1.73%, and 5 years is 4.32%.

b) The price of the security is $128.31.

a) To find the zero rates for all 5 maturities, we can use the formula for the present value of a bond:

PV = C / [tex](1+r)^n[/tex]

where PV is the present value,

C is the coupon payment,

r is the zero rate, and

n is the number of years to maturity.

We can solve for r by rearranging the formula:

r = [tex](C/PV)^{(1/n) }[/tex]- 1

Using the bond data given in the question, we can calculate the zero rates for each maturity as follows:

For the 1-year bond, PV = 98 and C = 0, so r = 2.01%.

For the 2-year bond, PV = 101, C = 2.48, and n = 2, so r = 2.48%.

For the 3-year bond, PV = 103, C = 2.91, and n = 3, so r = 2.77%.

For the 4-year bond, PV = 101, C = 2, and n = 4, so r = 1.73%.

For the 5-year bond, PV = 103, C = 5, and n = 5, so r = 4.32%.

Alternatively, we can use linear algebra to find the zero rates. We can write the present value equation in matrix form:

PV = A × x

where A is a matrix of coefficients, x is a vector of unknowns (the zero rates), and PV is a vector of present values.

To solve for x, we can use the equation:

x = ([tex]A^{-1}[/tex]) x PV

where ([tex]A^{-1}[/tex]) is the inverse of matrix A.

Using this method, we can solve for the zero rates as follows:

[2.01% ]

[2.48% ]

[2.77% ] = x

[1.73% ]

[4.32% ]

PV = [tex]A^{-1}[/tex] x  [98]

                   [101]

                   [103]

                   [101]

                   [103]

PV =   [-0.0201]

          [ 0.0248]

          [ 0.0277]

          [-0.0173]

          [ 0.0432]

b) To find the price of the security which pays cash flows of $10 in one year, $25 in two years, and $100 in four years, we can use the formula for the present value of a series of cash flows:

PV = [tex]C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^4[/tex]

where PV is the present value, C1, C2, and C3 are the cash flows, r is the zero rate, and the exponents correspond to the number of years until each cash flow is received.

Using the zero rates calculated in part (a), we can calculate the present value of each cash flow:

PV1 = $10 /(1+2.01 % [tex])^1[/tex] = $9.80

PV2 = $25/(1+2.48%[tex])^2[/tex] = $22.15

PV3 = $100/(1+1.73%[tex])^4[/tex] = $81.36

Then, the price of the security is the sum of the present values:

PV = $9.80 + $22.15 + $81.36 = $128.31

Therefore, the price of the security is $128.31.

How many hamburgers were sold on Sunday

Let's assume that the number of hamburgers sold on Sunday was x.

According to the problem, the number of cheeseburgers sold was three times the number of hamburgers sold.

Therefore, the number of cheeseburgers sold can be expressed as 3x.

The total number of hamburgers and cheeseburgers sold was 356.

Therefore, we can write an equation to represent this information:

x + 3x = 356

Simplifying the left-hand side of the equation, we get:

4x = 356

Dividing both sides by 4, we get:

x = 89

a) Less than 200mg/dl
b) More than 200mg/dl
c) Between 190mg/dl and 210mg/dl
d) Write a brief report on the guidance you would give a woman having high cholesterol level in this age group

Answers

a) The probability of a given woman in this age group having a cholesterol level less than 200mg/dl is 6.68%.

b) The probability of a given woman in this age group having a cholesterol level more than 200mg/dl is 93.32%.

c) The probability of a given woman in this age group having a cholesterol level between 190mg/dl and 210mg/dl is 15.87%.

d) If a woman in this age group has a cholesterol level higher than 230mg/dl, it is considered high and puts her at risk of heart disease

To calculate the probability of a given woman in this age group having a cholesterol level less than 200mg/dl, we need to find the z-score first. The z-score is the number of standard deviations that a given value is from the mean. The formula to calculate the z-score is:

z = (x - μ) / σ

where x is the given value, μ is the mean, and σ is the standard deviation.

For a cholesterol level of 200mg/dl, the z-score is:

z = (200 - 230) / 20 = -1.5

We can then use a z-table or calculator to find the probability of a z-score being less than -1.5, which is 0.0668 or approximately 6.68%.

Next, to find the probability of a given woman in this age group having a cholesterol level more than 200mg/dl, we can use the same process but subtract the probability of a z-score being less than -1.5 from 1 because the total probability is always 1.

So, the probability of a given woman in this age group having a cholesterol level more than 200mg/dl is:

1 - 0.0668 = 0.9332 or approximately 93.32%.

Finally, to find the probability of a given woman in this age group having a cholesterol level between 190mg/dl and 210mg/dl, we need to find the z-scores for both values.

For a cholesterol level of 190mg/dl, the z-score is:

z = (190 - 230) / 20 = -2

For a cholesterol level of 210mg/dl, the z-score is:

z = (210 - 230) / 20 = -1

We can then use the z-table or calculator to find the probability of a z-score being between -2 and -1, which is 0.1587 or approximately 15.87%.

Finally, a brief report on the guidance that you would give a woman having high cholesterol levels in this age group is:

It is essential to make lifestyle changes such as eating a healthy diet, exercising regularly, quitting smoking, and managing stress to lower cholesterol levels.

Statistical significance does not necessarily imply practical significance, and there may still be a meaningful difference between the groups that is not detected by the statistical test.

Additionally, the interpretation of a p-value depends on the study design, sample size, and other factors, and should be considered in conjunction with other information about the study.

The value of "a" is approximately 1.83 given that the absolute value of the difference of the two roots of the quadratic equation "ax squared plus 5x minus 3 equals 0" is the square root of 61 divided by 3, and "a" is positive.

We are given that the absolute value of the difference between the two roots of the quadratic equation "ax squared plus 5x minus 3 equals 0" is the square root of 61 divided by 3, and "a" is positive. We need to find the value of "a".

Let the two roots of the equation be r1 and r2, where r1 is not equal to r2. Then, we have:

|r1 - r2| = √(61) / 3

The sum of the roots of the quadratic equation is given by r1 + r2 = -5 / a, and the product of the roots is given by r1 × r2 = -3 / a.

We can express the difference between the roots in terms of the sum and product of the roots as follows:

r1 - r2 = √((r1 + r2)² - 4r1r2)

Substituting the expressions we obtained earlier, we have:

r1 - r2 = √(((-5 / a)²) + (4 × (3 / a)))

Simplifying, we get:

r1 - r2 = √((25 / a²) + (12 / a))

Taking the absolute value of both sides, we get:

|r1 - r2| = √((25 / a²) + (12 / a))

Comparing this with the given expression |r1 - r2| = √(61) / 3, we get:

√((25 / a²) + (12 / a)) = √(61) / 3

Squaring both sides and simplifying, we get:

25 / a² + 12 / a - 61 / 9 = 0

Multiplying both sides by 9a², we get:

225 + 108a - 61a² = 0

Solving this quadratic equation for "a", we get:

a = (108 + √(108² + 4 × 61 × 225)) / (2 × 61)

Since "a" must be positive, we take the positive root:

a = (108 + √(108² + 4 × 61 × 225)) / (2 × 61) ≈ 1.83

Therefore, the value of "a" is approximately 1.83.

A primary credit cardholder's card has an APR of 22. 99%. The current monthly balance, before interest, is $4,528. 34. Determine how much more the cardholder will pay, making monthly payments of $200, until the balance is paid off, instead of paying off the current balance in full

Answers

The cardholder will pay an additional $1,471.66 in interest by making monthly payments of $200 until the balance is paid off instead of paying off the current balance in full.

First, we need to calculate the total interest that will accrue on the current balance of $4,528.34. We can do this using the formula

Interest = Balance x (APR/12)

where APR is the annual percentage rate and is divided by 12 to get the monthly interest rate. Plugging in the values, we get:

credit card Interest = $4,528.34 x (22.99%/12) = $87.80

So the total interest that will accrue on the current balance is $87.80.

Next, we need to calculate how long it will take to pay off the balance by making monthly payments of $200. We can use a credit card repayment calculator to do this, but we'll use a simplified formula here

Months = -log(1 - (Balance x (APR/12))/Payment) / log(1 + (APR/12))

where Payment is the monthly payment amount. Plugging in the values, we get

Months = -log(1 - ($4,528.34 x (22.99%/12))/$200) / log(1 + (22.99%/12)) = 29.6 months

So it will take about 30 months (or 2.5 years) to pay off the balance by making monthly payments of $200.

Finally, we can calculate how much more the cardholder will pay in total by subtracting the current balance from the total amount paid over 30 months

Total amount paid = $200 x 30 = $6,000

Total interest paid = $6,000 - $4,528.34 = $1,471.66

The Johnson family lives 432 miles from the beach. They drive 52% of the distance before stopping for lunch. About how many miles do they drive before lunch? Explain how you can use mental math to find the answer.​

Answers

To find the distance the Johnson family drives before stopping for lunch, we can multiply the total distance to the beach by the percentage of the distance they drive before stopping for lunch.

52% of 432 miles can be found by multiplying 0.52 by 432:

0.52 * 432 = 224.64 miles

To use mental math to find the answer, we can round 432 to 400, which makes the calculation easier.

52% of 400 can be found by multiplying 0.5 by 400 and adding 2% of 400:

0.5 * 400 + 0.02 * 400 = 200 + 8 = 208 miles

Then, we can adjust for the fact that we rounded 432 to 400 by adding 32/400, which is 0.08, to the result:

208 + 0.08 * 432 = 208 + 34.56 = 242.56 miles

Therefore, the Johnson family drives about 242.56 miles before stopping for lunch.

The correct answer is: Fast Chicken, because it has a smaller median.

What is median?

Median is a measure of central tendency that represents the middle value in a dataset when the values are arranged in order of magnitude. To find the median, you need to arrange the values in order from smallest to largest and then find the middle value.

Based on the information provided, the drive-thru restaurant with less wait time is Fast Chicken, as it has a smaller median wait time of 12.5 minutes compared to the median wait time of 12 minutes for Super Fast Food. The mean wait time is not given, and even if it were, the median is a better measure of central tendency to compare in this scenario, as the box plots suggest some potential outliers.

2. x = 9.7 for f(x) and x = 50 for g(x), f(x) reaches 100 first.

1. Which function reaches 50 first?

To answer this, we need to solve for x in each function when the output is 50:

For f(x): 50 = 10x + 3

47 = 10x

x = 4.7

For g(x): 50 = 2x

x = 25

Since x = 4.7 for f(x) and x = 25 for g(x), f(x) reaches 50 first.

2. Which function reaches 100 first?

Similarly, we'll solve for x in each function when the output is 100:

For f(x): 100 = 10x + 3

97 = 10x

x = 9.7

For g(x): 100 = 2x
x = 50

Since x = 9.7 for f(x) and x = 50 for g(x), f(x) reaches 100 first.

Answers

The given information describes the measures of two angles, A and B. Angle A is represented as ∠A and has a measure of 6x-2 degrees. Angle B is represented as ∠B and has a measure of 4x+48 degrees. These measures are respectively shown in the colors #11accd and #28ae7b.

The question gives us two equations, one for angle A and one for angle B, in terms of x. We will have to solve for x and then find the measure of angle A.

To solve for x, we can set the expressions for ∠A and ∠B equal to each other and solve for x

∠A = ∠B

6x - 2 = 4x + 48

Subtracting 4x from both sides we get

2x - 2 = 48

Adding 2 to both sides we get

2x = 50

Dividing by 2 we get

x = 25

Now that we have found the value of x, we can substitute it into the expression for ∠A

∠A = 6x - 2

∠A = 6(25) - 2

By multiplying 6 with 25 we get

∠A = 150 - 2

By Subtracting we get

∠A = 148

Hence, the measure of angle A is 148 degrees.

Which are the coordinates of the vertex of F(x)=x^2-2x-3

Answers

Therefore , the solution of the given problem of coordinates comes out to be  (1, -4) are the coordinates of the vertex of the function  F(x) = x² - 2x - 3.

What does coordinate plane actually mean?

When used in connection with particular other algebraic components on this place, such as Euclidean space, a parameter can reliably detect placement using a number of qualities or coordinates. Coordinates, which appear as collections of numbers when traversing in reflected space, can be utilised to identify particular places or things. Using the two y & x measurements, one can find something over both sides.

Here,

The formula x = -b/2a can be used to determine the vertex of a quadratic function with the form

F(x) = ax² + bx + c. A and B are equal in the given function

=>  F(x) = x² - 2x - 3.

With these values entered into the formula, we obtain:

=> x = -b/2a x = -(-2)/(2*1)

=> x = 2/2 x = 1

Consequently, the vertex's x-coordinate is 1.

Now, we can enter the value of x into the following function, F(x), to determine the vertex's y-coordinate:

=> F(1) = 1² - 2(1) - 3

=> F(1) = 1 - 2 - 3

=> F(1) = -4

Therefore, the vertex's y-coordinate is -4.

As a result, (1, -4) are the coordinates of the vertex of the function

=> F(x) = x² - 2x - 3.
