El señor Rodríguez firma un pagaré por $675 a 8 meses de plazo y al 10%. Si efectúa dos pagos antes del vencimiento, uno por $150 a los 2 meses, y otro por $200 a los 4 meses, ¿cuál es el saldo que debe pagar al vencerse el pagaré?

Answers

Answer 1

Answer:

El saldo que el Sr. Rodríguez debe pagar cuando vence el pagaré es de $ 370

Step-by-step explanation:

Los parámetros dados del préstamo son;

El monto principal del préstamo, P = $ 675

La duración del préstamo, T = 8 meses = 2/3 años

La tasa de interés aplicada al préstamo, R = 10%

La cantidad que paga el Sr. Rodríguez en el segundo mes = $ 150

La cantidad que paga el Sr. Rodríguez en el cuarto mes = $ 200

Interés simple = P · R · T / 100 = 675 × 10 × 2/3/100 = 45

El interés simple del préstamo, I = $ 45

La cantidad total que el Sr. Rodríguez tiene que pagar, A = P + I = 675 + 45 = 720

La cantidad de reembolso que realiza el Sr. Rodríguez, R = 150 + 200 = 350

El saldo que debe pagar el señor Rodríguez, B = 720 - 350 = 370

El saldo que el señor Rodríguez debe pagar cuando el pagaré no vence, B = $ 370

Answer 2

Al vencerse el pagaré el señor Rodríguez deberá pagar $370.

Dado que el señor Rodríguez firma un pagaré por $675 a 8 meses de plazo y al 10%, si efectúa dos pagos antes del vencimiento, uno por $150 a los 2 meses, y otro por $200 a los 4 meses, para determinar cuál es el saldo que debe pagar al vencerse el pagaré se debe realizar el siguiente cálculo:

10/12 x 8 = 6.666(675 x 1.06666) - 150 - 200 = X720 - 350 = X370 = X

Por lo tanto, al vencerse el pagaré el señor Rodríguez deberá pagar $370.

Ravi works as a tutor for an hour and as a waiter for an hour. This month, he worked a combined total of hours at his two jobs. Let be the number of hours Ravi worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.

Answers

The expression for his total earnings can be derived by multiplying the number of tutoring hours by the tutoring rate and adding it to the product of the number of waiter hours and the waiter rate.

Let's assume the hourly rate for Ravi's tutoring job is "t" dollars and the hourly rate for his waiter job is "w" dollars.

Since Ravi worked as a tutor for "x" hours this month, he earned a total of x * t dollars from his tutoring job.

Similarly, as he worked as a waiter for 1 hour each day this month, he earned a total of 1 * w dollars from his waiter job.

To calculate the combined total dollar amount he earned this month, we can express it as x * t + 1 * w, which represents the earnings from his tutoring job plus the earnings from his waiter job.

This expression provides the total dollar amount Ravi earned based on the given hourly rates and the number of tutoring hours.

(01.08 mc) a high school's student council wants to purchase spirit shirts for its upcoming homecoming event. purchases of 25 shirts or less cost $20 per shirt, plus $20 shipping and handling. when more than 25 shirts are ordered, the price is $15 per shirt, plus $15 shipping and handling. if $720 was spent on shirts, how many shirts did the student council order?

Answers

When more than 25 shirts are ordered, the price is $15 per shirt, plus $15 shipping and handling.  If $720 was spent on shirts,  the student council ordered 47 shirts.

Let x be the number of shirts ordered. We can set up an equation based on the given information:

If x ≤ 25, then the cost of the shirts is 20x + 20.

If x > 25, then the cost of the shirts is 15x + 15.

We know that the total cost of the shirts is $720. So, we can write:

20x + 20 if x ≤ 25

15x + 15 if x > 25

Setting these equal to each other, we get:

20x + 20 = 15x + 15

5x = 5

x = 1

This doesn't make sense, because the number of shirts ordered must be greater than 1. Therefore, we know that the student council ordered more than 25 shirts.

Using the equation 15x + 15 = 720, we can solve for x:

15x + 15 = 720

15x = 705

x = 47

To check, we can calculate the cost of the shirts:

If 47 shirts are ordered, then the cost is 15(47) + 15 = $720.

Answers

To compute the z-score for the applicant, we can use the formula:

z = (x - μ) / σ

Where:

x is the applicant's score

μ is the mean

σ is the standard deviation

Given that the applicant's score is 21.0, the mean is 18.0, and the standard deviation is -3.0, we can substitute these values into the formula to calculate the z-score.

z = (21.0 - 18.0) / (-3.0)

z = 3.0 / -3.0

z = -1.0

Therefore, the z-score for the applicant is -1.0.

he line y =-x passes through the origin in the xy-plane, what is the measure of the angle that the line makes with the positive x-axis?

Answers

The line y = -x, passing through the origin in the xy-plane, forms a 45-degree angle with the positive x-axis.

The slope-intercept form of a linear equation is y = mx + b, where m represents the slope of the line. In this case, the equation y = -x has a slope of -1. The slope indicates the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

To determine the angle between the line and the positive x-axis, we need to find the angle that the line's slope makes with the x-axis. Since the slope is -1, the line rises 1 unit for every 1 unit it runs. This means the line forms a 45-degree angle with the x-axis.

The angle can also be determined using trigonometry. The slope of the line (-1) is equal to the tangent of the angle formed with the x-axis. Therefore, we can take the inverse tangent (arctan) of -1 to find the angle. The arctan(-1) is -45 degrees or -π/4 radians. However, since the line is in the positive x-axis direction, the angle is conventionally expressed as 45 degrees or π/4 radians.

a man has 32 coins in his pocket, all of which are dimes and quarters. if the total value of his change is 620 cents, how many dimes and how many quarters does he have? your answer is

Answers

If the total value of his change is 620 cents, the man has 12 dimes and 20 quarters in his pocket.

Let's assume that the man has x dimes and y quarters in his pocket. We know that he has 32 coins in total,

x + y = 32.

We also know that the total value of his change is 620 cents, which can be expressed as

10x + 25y = 620.

To solve for x and y, we can use either substitution or elimination. Let's use substitution. Solving the first equation for x, we get

x = 32 - y.

Substituting this into the second equation, we get

10(32 - y) + 25y = 620

Simplifying this equation, we get

320 - 10y + 25y = 620

which yields

15y = 300.

Therefore, y = 20, and x = 32 - 20 = 12.

So the man has 12 dimes and 20 quarters in his pocket. We can check that this is correct by verifying that

12(10) + 20(25)

= 120 + 500

= 620.

In summary, we can solve the problem by setting up a system of equations, either using substitution or elimination to solve for the variables, and then checking our answer to make sure it is correct.

Planes x = 2, y = 4 and z =4, respectively, carrying charges of 14nC/m², 17nC/m² and 22nC/m². If the line charges of 10nC/m, 15nC/m and 20nC/m at x = 10, y = 5; y=6, z = 5 and x 9, z = 6, respectively. Calculate the total electric flux density at the following locations: a. P1(2, 2, 5)

Answers

The total electric flux density at P1(2, 2, 5) is 66,102.3 Nm²/C.

To calculate the total electric flux density at P1(2, 2, 5), we'll use Gauss's law:  ΦE = q/ε₀. Where ΦE represents the total electric flux, q is the net charge inside the closed surface, and ε₀ is the permittivity of free space. We'll need to first determine the total charge enclosed by the Gaussian surface at P1(2,2,5).

Here are the steps to do so:

Step 1: Define the Gaussian surface

We'll define a Gaussian surface such that it passes through P1(2, 2, 5), as shown below: \(\vec{A}\) is the area vector, which is perpendicular to the Gaussian surface. Its direction is pointing outward.

Step 2: Calculate the net charge enclosed by the Gaussian surfaceThe Gaussian surface passes through the three planes x=2, y=4 and z=4, which carry charges of 14nC/m², 17nC/m² and 22nC/m², respectively. The Gaussian surface also passes through four line charges: 10nC/m, 15nC/m, 15nC/m, and 20nC/m.

We'll use these charges to find the total charge enclosed by the Gaussian surface.q = Σqinwhere qin is the charge enclosed by each part of the Gaussian surface. We can calculate qin using the surface charge density for the planes and the line charge density for the lines.

For example, the charge enclosed by the plane x = 2 isqin = σA

where σ = 14nC/m² is the surface charge density and A is the area of the part of the Gaussian surface that intersects with the plane. Since the Gaussian surface passes through x = 2 at y = 2 to y = 4 and z = 4 to z = 5, we can find A by calculating the area of the rectangle defined by these points: A = (4-2) x (5-4) = 2m²

Therefore,qx=2 = σxA = 14nC/m² x 2m² = 28nC

Similarly, the charge enclosed by the planes y = 4 and z = 4 are qy=4 = σyA = 17nC/m² x 2m² = 34nC and qz=4 = σzA = 22nC/m² x 2m² = 44nC, respectively.

For the lines, we'll use the line charge density and the length of the part of the line that intersects with the Gaussian surface. For example, the charge enclosed by the line at x = 10, y = 5 isqin = λlwhere λ = 10nC/m is the line charge density and l is the length of the part of the line that intersects with the Gaussian surface. The part of the line that intersects with the Gaussian surface is a straight line segment that goes from (2, 5, 5) to (10, 5, 5), which has a length of l = √((10-2)² + (5-5)² + (5-5)²) = 8m

Therefore,qx=10,y=5 = λl = 10nC/m x 8m = 80nC

Similarly, the charges enclosed by the other lines are:qy=6,x=10 = λl = 15nC/m x 8m = 120nCqy=5,x=9 = λl = 15nC/m x 8m = 120nCqz=6,x=9 = λl = 20nC/m x 8m = 160nCTherefore, the total charge enclosed by the Gaussian surface is:q = qx=2 + qy=4 + qz=4 + qy=5,x=10 + qy=6,x=10 + qy=5,x=9 + qz=6,x=9= 28nC + 34nC + 44nC + 80nC + 120nC + 120nC + 160nC = 586nC

Step 3: Calculate the total electric flux density at P1(2, 2, 5)We can now use Gauss's law to find the total electric flux density at P1(2, 2, 5).ΦE = q/ε₀ε₀ = 8.85 x 10^-12 F/mΦE = (586 x 10^-9 C)/(8.85 x 10^-12 F/m)ΦE = 66,102.3 Nm²/C

How to evaluate for the solutions of the equations by elimination

we shall write the equations as:

2x - 3y = 50...(1)

7x + 8y = -10...(2)

multiply equation (1) by 7 to get equation (3) and equation (2) by 2 to get equation (4)

7(2x - 3y) = 7 × 50

14x - 21y = 350...(3)

2(7x + 8y) = 2 × -10

14x + 16y = -20...(4)

subtract equation (3) from (4) to eliminate x

14x + 16y - 14x + 21y = -20 - 350

37y = -370

divide through by 37

y = -10

put the value -10 for y in equation (1) to get x

2x - 3(-10) = 50

2x + 30 = 50

2x = 50 - 30 {subtract 30 from both sides}

2x = 20

x = 20/2 {divide through by 2}

x = 10

Answer:

See attachment below

Step-by-step explanation:

For the first option, we are given m = - 2 / 3, b = 3. This is likely in the point - slope form y = mx + b, where m = slope and b = y - intercept. Thus, the equation of the line in point - slope form given this information, should be y = - 2 / 3x + 3. It seems as if none of the following equations match this form, so let us interchange the equation a bit,

y = - 2 / 3x + 3,

y + 2 / 3x = 3,

2x + 3y = 9 - Option C

_______________________________________________________

Next we are given m = - 3 / 2, and that this line passes through the point ( 4, - 1 ). Substitute m as - 3 / 2, x as 4, y as - 1, knowing point ( 4, - 1 ), into the form y = mx + b - solving for b.

- 1 = ( - 3 / 2 )( 4 ) + b,

b = 5,

Thus the equation in point - slope form should be y = - 3 / 2x + 5. None of the choices match this, so let us again alter the equation,

y = - 3 / 2x + 5,

2y = - 3x + 10,

- 2y = 3x - 10 - Option A

_______________________________________________________

( 6, 3 ) and ( 3, 1 ) is given to lie on this line. The slope of the line should be as follows,

Slope = 3 - 1 / 6 - 3 = 2 / 3

Now let us determine the y - intercept ( b ) by substitute one of the points, say ( 6, 3 ). In this case x = 6, and y = 3,

3 = ( 2 / 3 )( 6 ) + b,

b = - 1,

y = 2 / 3x - 1 = Option D

in a random sample of 100 ucla students, 35 have travelled outside the us. estimate the true population proportion of ucla students who travelled outside the us using a 99% confidence interval. find the most reasonable formula to find the interval.

Answers

The most reasonable formula to find the interval is

0.35 ± 2.576 (√ (0.35 × 0.65)/100).

The subset chosen from the larger set to make assumptions is known as a random sample. A range of values is a confidence interval.  

According to the given problem, n =100 and x = 35

To estimate the true population of students who travelled outside the US using a 99% confidence interval:

p   =   x / n

    =   35 / 100

p   =   0.35

At 99% confidence,

α   =   1 - 0.99

α   =   0.01

α/2   =   0.01/2

α/2   =   0.005

∴  z(α/2)   =   \(z_{0.005}\)   =   2.576

99% confidence interval (CI) is,

CI    =   p ± z(α/2) * √(p(1-p)/n)

      =   0.35 ± 2.576 * \(\sqrt{\frac{0.35(1-0.35)}{100} }\)

      =   0.35 ± 2.576 * \(\sqrt{\frac{0.35(0.65)}{100} }\)

      =   0.35 ± 2.576 * \(\sqrt{\frac{0.2275}{100} }\)

      =   0.35 ± 2.576 * \(\sqrt{0.002275}\)

      =   0.35 ± 2.576 * 0.0476969600

      =   0.35 ± 0.122867391

      =   ( 0.35 - 0.1229,0.35 + 0.1229 )

CI    =   ( 0.2271,0.4729 )

Therefore, the most reasonable formula to find the interval is,

0.35 ± 2.576 × \(\sqrt{\frac{0.35 * 0.65}{100} }\)

The population of an island was 2 million in 1950. The population grew in an exponential trend for 63 years and became 6.5 million in 2013. It is estimated that the carrying capacity of the island is 10 million. Assuming the population growth rate in the future remains the same as in the last 50 years, what will be the population of the island in 2050? (Assume constant carrying capacity and consumption/capita.)

Answers

The population of an island in 1950 was 2 million. The population grew exponentially for 63 years and reached 6.5 million in 2013. The carrying capacity of the island is estimated to be 10 million.

If the population growth rate in the future is similar to the last 50 years, what will the population be in 2050

The population is given to be increasing exponentially, which means it will follow the equation:

\($P(t) = P_0 e^{rt}$\)Here,\($P(t)$\) is the population after a period of time \($t$, $P_0$\) is the initial population, $r$ is the annual growth rate (which we are given is the same as the growth rate of the last 50 years), and \($t$\) is the time.

We can find the annual growth rate $r$ using the formula:\($$r = \frac{\ln{\frac{P(t)}{P_0}}}{t}$$\)
We know\($P_0 = 2$ million, $P(t) = 6.5$ million, and $t = 63$\) years. Substituting these values, we get:

\($r = \frac{\ln{\frac{6.5}{2}}}{63} = 0.032$\) (rounded to 3 decimal places)

Since the carrying capacity of the island is 10 million, we know that the population will not exceed this limit.

Therefore, we can use the logistic model to find the population growth over time. The logistic growth model is:

\($$\frac{dP}{dt} = r P \left(1 - \frac{P}{K}\right)$$\)

where $K$ is the carrying capacity of the environment. This can be solved to give:\($P(t) = \frac{K}{1 + A e^{-rt}}$\)

where \($A = \frac{K-P_0}{P_0}$. We know $K = 10$ million, $P_0 = 2$ million, and $r = 0.032$\). Substituting these values, we get:\($A = \frac{10-2}{2} = 4$\)

Therefore, the equation for the population of the island is:\($P(t) = \frac{10}{1 + 4 e^{-0.032t}}$\)

To find the population in 2050, we substitute\($t = 100$\) (since 63 years have already passed and we want to find the population in 2050, which is 100 years after 1950):

\($P(100) = \frac{10}{1 + 4 e^{-0.032 \times 100}} \approx \boxed{8.76}$ million\)
Therefore, the estimated population of the island in 2050, assuming constant carrying capacity and consumption per capita, is approximately 8.76 million.

Answers

Answer:

The y coordinates of B' is: 8

Step-by-step explanation:

Given

\(A = (-5,2)\)

\(B =(1,2)\)

\(C = (-4,1)\)

\(D = (-5,-4)\)

Translation of (x, y) → (x + 6, y – 10)  ---Missing from the question

Required

Determine the y coordinates of B'

We have:

(x, y) → (x + 6, y – 10)  

And

\(B =(1,2)\)

So the translation from B to B' is:

\(B (1,2) \to B'(1+6,2-10)\)

\(B (1,2) \to B'(7,-8)\)

So, we have:

\(B' = (7,-8)\)

suppose a baseball pitcher throws fastballs 80% of the time and curveballs 20% of the time. suppose a batter hits a home run on 8% of all fastball pitches, and on 5% of all curveball pitches. what is the probability that this batter will hit a home run on this pitcher’s next pitch?

Answers

The probability that this batter will hit a home run on this pitcher's next pitch is approximately 0.074, or 7.4%.

To determine the probability that the batter will hit a home run on the pitcher's next pitch,

we need to consider the probabilities of the pitcher throwing a fastball and a curveball, as well as the probabilities of hitting a home run on each type of pitch.

Given that the pitcher throws fastballs 80% of the time and curveballs 20% of the time, we can calculate the probability of the batter facing each type of pitch:

- Probability of facing a fastball = 80% = 0.8
- Probability of facing a curveball = 20% = 0.2

Now, we need to determine the probability of hitting a home run on each type of pitch:

- Probability of hitting a home run on a fastball = 8% = 0.08
- Probability of hitting a home run on a curveball = 5% = 0.05

To find the overall probability of hitting a home run on the pitcher's next pitch, we can use the following formula:

Overall probability = (Probability of facing a fastball * Probability of hitting a home run on a fastball) + (Probability of facing a curveball * Probability of hitting a home run on a curveball)

Plugging in the values we have:

Overall probability = (0.8 * 0.08) + (0.2 * 0.05)
Overall probability = 0.064 + 0.01
Overall probability = 0.074

Therefore, the probability that this batter will hit a home run on this pitcher's next pitch is approximately 0.074, or 7.4%.
