Find the Value of X.

The sine of 48 Degrees is equal to one-half.

The cosine of an angle is equal to one-half when the angle is 60 degrees. Therefore, if the cosine of 42 degrees is one-half, it means that the angle of 42 degrees is complementary to the angle of 60 degrees.

Since the angles are complementary, the sine of one angle is equal to the cosine of the other angle. In this case, the sine of 48 degrees will be equal to the cosine of its complementary angle, which is 42 degrees.

Therefore, the sine of 48 degrees is equal to one-half.

The correct answer is: 1/2, because the angles are complementary.

The dimensions of the container in the shape of a rectangular solid are 3.41 m by 4.41 m by 7.81 m.

Let the width of the container be w.

The length of the container is w + 1.

The height of the container is 2w + 1.

The volume of the container is 84 m3.

Set up the following equation to represent the volume of the container:

w(w + 1)(2w + 1) = 84

Solve for w by expanding the left-hand side of the equation:

2w³ + 3w² + w - 84 = 0

Then use the quadratic formula to solve for w:

w = (-3 ± √(3² - 4 × 2 × (-84))) / (4 × 2)

w = (-3 ± √(9 + 672)) / 8

w = (-3 ± √681) / 8

w = (-3 ± 26.09) / 8

w = 3.41 or -5.59

Since w is the width of the container, it must be positive. Therefore, w = 3.41.

The length of the container is w + 1 = 3.41 + 1 = 4.41.

The height of the container is 2w + 1 = 2 × 3.41 + 1 = 7.81.

Therefore, the dimensions of the container are 3.41 m by 4.41 m by 7.81 m.

Answer:

x = 30

y = 120

Step-by-step explanation:

okay so , 3x - 30 = 60 (opposite each other)

60 + 30 = 90

90 / 3 = 30

x = 30

all angles have to equal 360

we already have two 60 degrees

60 + 60 = 120

360 - 120 = 240

240 / 2 = 120

y = 120

The value of y when a = 1 and b = 2 is 22.

The equation of can be solved as follows: We will substitute the value of a and b  in the equation to find the value of y.

Therefore,

y = 3ab + 2b³

Let's find y when a = 1 and b = 2

Answer:

To calculate each person's share, we first add up the parts of the ratio, which is 1+3+6=10.

Next, we divide the total amount shared, GH4000, by the ratio sum (10):

GH4000/10= GH400

Finally, to find each person's share, we multiply the ratio part by GH400:

- Harrison's share: 1 part out of 10 parts = 1/10 * GH4000 = GH400

- Anny's share: 3 parts out of 10 parts = 3/10 * GH4000 = GH1200

- Ekua's share: 6 parts out of 10 parts = 6/10 * GH4000 = GH2400

Therefore, Harrison's share is GH400, Anny's share is GH1200, and Ekua's share is GH2400.

There were 5 1/4 bags of popcorn left after eating 4 bags.

To find out how much popcorn was left after eating 4 bags, we need to subtract the amount eaten from the total amount Brianna made.

Brianna made 9 1/4 bags of popcorn, which can be represented as a mixed number. To perform calculations, let's convert it to an improper fraction:

9 1/4 = (4 * 9 + 1) / 4 = 37/4

Now, let's subtract the 4 bags eaten from the total:

37/4 - 4

To subtract fractions, we need a common denominator. The common denominator of 4 and 1 is 4. Therefore, we can rewrite the expression as:

37/4 - 4/1

Now, let's find a common denominator and subtract the fractions:

37/4 - 16/4 = (37 - 16) / 4 = 21/4

The result is 21/4, which is an improper fraction. Let's convert it back to a mixed number:

21/4 = 5 1/4

Therefore, there were 5 1/4 bags of popcorn left after eating 4 bags.

Rajani's age is calculated to be 24 years old.

Let's assume the two-digit number representing Rajani's age is written as AB,

where

A represents the tens digit and

B represents the units digit.

According to the given information, Rajani's age, AB, is equal to:

Based on this information, we can form the equation:

10A + B = 4(A + B) + 6(A * B)

10A + B = 4A + 4B + 6AB

rearranging the terms:

10A - 4A = 4B + 6AB - B

6A = 3B + B(6A - 4)

6A = 3B + 2B(3A - 2)

Dividing both sides by 3A - 2:

6A / (3A - 2) = 3B / (3A - 2) + 2B

at this point, we need to check the possible values for A and B that satisfy this equation. Since the problem states that Rajani's age consists of two digits, A and B must be integers ranging from 0 to 9.

By trying different values for A and B, we find that A = 2 and B = 4 satisfy the equation:

6 * 2 / (3 * 2 - 2) = 3 * 4 / (3 * 2 - 2) + 2 * 4

12 / 4 = 12 / 4 + 8

3 = 3 + 8

To calculate the annuity payment for each of the given scenarios, we can use the formula for the present value of an ordinary annuity:

Annuity Payment = Future Value / [(1 - (1 + r)^(-n)) / r]

Where:

Future Value = Future value of the annuity

r = Interest rate per period (in decimal form)

n = Total number of periods

Let's calculate the annuity payment for each scenario:

Scenario 1:

Future Value = $25,850

Year = 8

Interest rate = 8% (0.08 as a decimal)

Annuity Payment = $25,850 / [(1 - (1 + 0.08)^(-8)) / 0.08]

Scenario 2:

Future Value = $1,130,000

Year = 43

Interest rate = 10% (0.10 as a decimal)

Annuity Payment = $1,130,000 / [(1 - (1 + 0.10)^(-43)) / 0.10]

Scenario 3:

Future Value = $976,000

Year = 29

Interest rate = 11% (0.11 as a decimal)

Annuity Payment = $976,000 / [(1 - (1 + 0.11)^(-29)) / 0.11]

Scenario 4:

Future Value = $149,000

Year = 16

Interest rate = 7% (0.07 as a decimal)

Annuity Payment = $149,000 / [(1 - (1 + 0.07)^(-16)) / 0.07]

After performing the calculations, you will obtain the annuity payment for each scenario.

Answer:

Average time per day = 1.2 hours per day
Average time per day = 72 minutes per day

Step-by-step explanation:

To find Clarence's average time per day, we need to divide the total time he takes to walk the 15.5 miles by the number of days he walks, which is five.

Let's calculate his average time per day:

Average time per day = Total time / Number of days

Since Clarence takes a total of 6 hours to walk the 15.5 miles, we'll divide 6 by 5 to find his average time per day:

Average time per day = 6 hours / 5

Average time per day = 1.2 hours per day

To convert hours to minutes, we'll multiply the average time per day by 60:

Average time per day = 1.2 hours * 60 minutes

Average time per day = 72 minutes per day

Therefore, Clarence's average time per day is 72 minutes.

Therefore, we can expect that approximately 95.45% of the 3000 metal rods produced will fall between 74.5 cm and 75.5 cm in length. To find the actual number, we multiply 0.9545 by 3000, yielding approximately 2864 rods.

To determine how many metal rods will be between 74.5 cm and 75.5 cm in length, we can use the properties of the normal distribution.

Given that the lengths of the metal rods are normally distributed with a mean of 75.0 cm and a standard deviation of 0.25 cm, we can calculate the probability of a rod falling within the specified range.

First, we find the z-scores for the lower and upper limits of the range. The z-score for 74.5 cm is

[tex]\frac{ (74.5 - 75.0) }{ 0.25} = -2,[/tex]

and the z-score for 75.5 cm is

[tex]\frac{(75.5 - 75.0)} { 0.25} = 2.[/tex]

Using a standard normal distribution table or a statistical calculator, we can determine the area under the curve between these z-scores, which represents the probability.

The solution to the system of equations is:

x = -36,

y = 23,

z = -10.

To solve the system of linear equations using the inverse method, we first need to represent the system in matrix form.

Let's rewrite the system of equations:

1x + 2y - 1z = 7 ...(1)

2x - 3y - 4z = -3 ...(2)

1x + 1y + 1z = 0 ...(3)

We can express this system in matrix form as AX = B, where:

A = [[1, 2, -1],

[2, -3, -4],

[1, 1, 1]]

X = [[x],

[y],

[z]]

B = [[7],

[-3],

Now, to solve for X, we need to find the inverse of matrix A. If A is invertible, we can solve for X by multiplying the inverse of A with B:

X = A⁻¹ × B

Let's calculate the inverse of matrix A:

A⁻¹ = [[-3, 5, -1],

[2, -3, 1],

[-1, 1, 0]]

Now, we can solve for X:

X = A⁻¹B

X = [[-3, 5, -1],

[2, -3, 1],

[-1, 1, 0]]  [[7],

Multiplying the matrices, we get:

X = [[-3×7 + 5(-3) + (-1)0],

[2×7 + (-3)(-3) + 10],

[-1×7 + 1(-3) + 0*0]]

X = [[-21 - 15 + 0],

[14 + 9 + 0],

[-7 - 3 + 0]]

X = [[-36],

Step-by-step explanation:

In the case of a hard money or short-term loan, the calculation for the monthly payment is slightly different. Typically, hard money loans have interest-only payments during the loan term, and the principal amount is due at the end of the term.

To calculate the monthly payment for an interest-only loan, you can use the following formula:

Monthly Payment = Loan amount * (Annual interest rate / 12)

Given:

Condo cost = $80,000

Down payment = $30,000

Loan amount = Condo cost - Down payment = $80,000 - $30,000 = $50,000

Annual interest rate = 6.00%

Loan term = 30 months

First, calculate the monthly interest rate:

Monthly interest rate = (Annual interest rate / 100) / 12 = (6.00 / 100) / 12 = 0.005

Next, substitute the values into the formula:

Monthly Payment = $50,000 * 0.005

After performing the calculations, the monthly payment for this hard money loan is $250.
