Step-by-step explanation:

Answer 2

Answer:

not proportional

Step-by-step explanation:

A graph that’s proportional would have to be linear a straight line but that cannot happen since the numbers are proportional

Its constant of proportionality is 12 and 10 so it could not work.

Paying 13 mortgage payments instead of 12 per year can save to you thousands in interest cost. If you had a $175,000 mortgage at 6% for 30 years, how much extra would you have to pay per year to make 13 instead of a 12 mortgage mortgage payments per year? How much would you pay if you paid 1/12 of it per month?

Answers

You would pay $14,583.33 per month if you divided the mortgage amount into equal monthly payments.

To calculate the additional amount you would have to pay per year to make 13 mortgage payments instead of 12, we need to determine the monthly mortgage payment first.

Using the formula for a fixed-rate mortgage:

[tex]M = \dfrac{P(r(1 + r)^n)} { ((1 + r)^n - 1)}[/tex]

M = P(r(1 + r)^n) / ((1 + r)^n - 1)

Here:

M = Monthly mortgage payment

P = Principal amount (mortgage amount)

r = Monthly interest rate (annual interest rate / 12)

n = Total number of payments (number of years × 12)

Let's calculate the monthly mortgage payment first:

P = $175,000

r = 6% / 12 = 0.005

n = 30 × 12 = 360

[tex]M = 175,000 \times\dfrac{ (0.005(1 + 0.005)^{360})}{ ((1 + 0.005)^{360} - 1)}[/tex]

M = $1,049.91

With a monthly mortgage payment of $1,049.91, we can calculate the additional amount you would need to pay per year to make 13 payments instead of 12.

Additional payment per year = Monthly payment × 12 - Monthly payment

Additional payment per year = $1,049.91 × 12 - $1,049.91

Additional payment per year = $12,599.92 - $1,049.91

Additional payment per year = $11,550.01

Therefore, you would need to pay $11,550.01 extra per year to make 13 mortgage payments instead of 12.

Now, let's calculate the amount you would pay if you made equal monthly payments throughout the year (1/12 of the mortgage amount per month).

Amount paid per month = Mortgage amount / 12

Amount paid per month = $175,000 / 12

Amount paid per month ≈ $14,583.33

Thus, you would pay $14,583.33 per month if you divided the mortgage amount into equal monthly payments.

The number increased by 25%.

Step-by-step explanation:

If you divide 32 into 40 (40 / 32), it will get you 1.25.

There are 12 boxes of books to put on shelves. Each box has 31 books.Each shelve holds 18 books. Kevin estimates he will need 20 shelves for all the books

Answers

Answer: False. 21 Shelves.

Step-by-step explanation:

First, 12 x 31= 372

This indicates that there are 372 books.

Then, 372 ÷ 18= 20.6666666667

Since we have a decimal that is above 4 we round up.

This leaves 21 shelves needed for all the books o fit on a shelf.

if the set of values represent points on a line, what is the value of a?

Answers

Answer:

a = 7

Step-by-step explanation:

Equation of line : y = mx + b

m = slope

Plug in coordinates:  

Slope = Change in y/Change in X

Slope = 13-4/5-2 = 9/3 = 3

Plug in coordinates:

y - intercept = b

13 = 5(3) + b

13 = 15 + b

b = -2

Equation: y = 3x - 2

Dante argues that point P is the circumcenter of the triangle. Determine if
Dante is correct and justify your answer.

Answers

Dante is incorrect because point P is not the circumcenter of the triangle.

What is the circumcenter of a triangle?

The circumcenter of a triangle is a specific point or location either inside or outside the triangle that represents the center if a circumcircle is drawn or if a circle that touches all the vertices of a triangle is drawn.

How to identify a circumcenter?

There are some simple characteristics to determine if a circumcenter is correct.

All the vertices of a triangle have the same distance from the circumcenter.In obtuse triangles like the one shown in the image, this point is located outside the triangle.

Based on these characteristics we can conclude Dante is incorrect because the distance from point P to the three vertices is not the same and this point should be located outside not inside the triangle.

What is a linear equation?

A straight line on a coordinate plane is represented by a linear equation. Y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept, which can be used to represent the equation (the point where the line intersects the y-axis).

The slope of a line, which reflects the steepness of the line, is calculated as the ratio of the change in y to the change in x between any two locations on the line. The line's intersection with the y-axis, or the value of y when x = 0, is known as the y-intercept.

The equation y = 0.8x represents the cost "y" of "x" packs of bubble gum. The coefficient of "x" in this equation is 0.8, which represents the cost per pack of bubble gum.

Therefore, the unit cost of bubble gum is $0.8 per pack.

Answers

By computing the product between his hourly wage and the number of hours he works per week, we will see that his weekly pay is $876.20

We know that Andrew charges $13.00 per hour, and we know that, in a week, he works for a total of 67.4 hours.

Then the money that he earns each week is just the product between the amount he wins per hour and the number of hours that he works each week.

This gives:

($13.00 h^-1)*(67.4 h) = $876.20

This means that Andrew wins $876.20 per week with this job.
