Does anyone know what the monthly payment is?:/

Answers

Answer:  700.22 dollars

====================================================

Explanation:

The formula given is

[tex]M = \frac{P*\left(\frac{r}{12}\right)*\left(1+\frac{r}{12}\right)^{12*t}}{\left(1+\frac{r}{12}\right)^{12*t}-1}\\\\[/tex]

which to be honest is a big ugly mess of variables. The fractions also make things even more messy. Through trial and error, you can find various ways to help clean up the formula.

Notice how the "r/12" seems to show up a lot. Let's replace that fraction with the variable A.

So we'll make A = r/12

Because of that, the expression [tex]\left(1+\frac{r}{12}\right)^{12*t}[/tex] turns into [tex]\left(1+A\right)^{12*t}[/tex]

After replacing all the "r/12" terms with "A", we have the formula

[tex]M = \frac{P*\left(\frac{r}{12}\right)*\left(1+\frac{r}{12}\right)^{12*t}}{\left(1+\frac{r}{12}\right)^{12*t}-1}\\\\[/tex]

turn into

[tex]M = \frac{P*A*\left(1+A\right)^{12*t}}{\left(1+A\right)^{12*t}-1}\\\\[/tex]

which is a bit simpler in my opinion.

------------------

We could also let

B = (1+A)^(12t)

which would then allow us to go from this

[tex]M = \frac{P*A*\left(1+A\right)^{12*t}}{\left(1+A\right)^{12*t}-1}\\\\[/tex]

to this

[tex]M = \frac{P*A*B}{B-1}\\\\[/tex]

and that's even more simple

---------------------

We're given the following values

P = 75,000 = amount loanedr = 0.023 = annual interest rate in decimal formt = 10 = number of years

Based on those values, we can say

A = r/12 = 0.023/12 = 0.00191667 approximatelyB = (1+A)^(12*t) = (1+0.00191667)^(12*10) = 1.25832348 approximately

From here, we plug the values of P, A, and B into the simplified version of the formula below.

[tex]M = \frac{P*A*B}{B-1}\\\\M \approx \frac{75000*0.00191667*1.25832348}{1.25832348-1}\\\\M \approx \frac{180.88431483087}{0.25832348}\\\\M \approx 700.22405563\\\\M \approx 700.22\\\\[/tex]

The monthly payment is roughly $700.22

During the month of june, jessica volunteers at a library every 6 days and at a veterinarians office every 10 days. jessica’s first visit to the library was on June 6 and her first visit to the veterinarian office was on June 1th.


What day in June will jessica volunteer at both locations?


Anwser Options

june 24

june 30

Answers

The day in June, Jessica volunteered at both locations if she volunteers at the library every 6 days and at a veterinarian's office every 10 days is June 30, so option F is correct.

What is LCM?

The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.

For instance: The LCM of 2 and 3 is 6.

Given:

Jessica volunteers library every 6 days,

Jessica's veterinarian's office, every 10 days,

So for her visit to both, the place takes the LCM of 6 and 10,

LCM of 6 and 10 = 30,

Hence, on the 30th day, she visits both places so if she starts volunteering from the 1st of June then she will visit both places on the 30th of June.

Therefore, The day in June, Jessica volunteered at both the location if she volunteers at a library every 6 days and at a veterinarian's office every 10 days. Jessica’s first visit to the library was on June 6 and her first visit to the veterinarian's office was on June, 1st is June 30.

Two lines intersect, and you know the measure of one angle. How can you determine the measures of the other three angles

Answers

Answer:

Opposite angles are the same measure.

Angles around a point = 360°

When you add all the angles, you get 360.

Angle a and b would measure the same and so would angle d and c. So you double the measure for one of those angles and subtract it from 360.

Then, you half that value( divide by 2) and this is to find the measure of the other angle

The answer is angle around the point =360

Mr. Litterski creates a ball from rubber bands.



The circumference of the ball is 9.4 inches. What is the approximate surface area and volume of the ball? Round your answers to the nearest unit. HELP PLEASE!!

Answers

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

[tex]A = 4\pi r[/tex]

In which r is the radius.

Volume:

[tex]V = \frac{4\pi r^3}{3}[/tex]

The circumference of the ball is 9.4 inches.

So the radius is:

[tex]6.2832r = 9.4[/tex]

[tex]r = \frac{9.4}{6.2832} = 1.53[/tex]

Surface area

[tex]A = 4\pi(1.53)^2 = 29.3[/tex]

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

[tex]V = \frac{4\pi (1.53)^3}{3} = 14.9[/tex]

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

Step-by-step explanation:

Given that

The return percentage is 7.5%

And, the monthly net is $810

We need to find the property listed price

Since we assume that the return percentage is on annual basis

So, for monthly, it is

= 7.5% ÷ 12

= 0.625%

Answer: See explanation

Step-by-step explanation:

Correlation is a term which simply measures the strength of the linear relationship that exist between two variables that are quantitative.

In the scenario in the question, since the correlation coefficient between the variables is +0.64, it means that there is a positive correlation between the two variables which means there's a positive relationship between the repeated visits to the coffee shop and the customer's age but they're weakly positively correlated .

Answers

Answer:

It is an arithmetic sequence and the common difference is 5

Step-by-step explanation:

4+5 = 9; 9+5=14 (adding is arithmetic, multiplying is geometric)

In an Arithmetic Sequence, there is a common number added or subtracted from each term to get the next
In a Geometric Sequence, there is a common number multiplied or divided from each term to get the next

4, 9, 14
(4+5) = 9
(9+5) = 14

So sequence is arithmetic and the common difference is 5
