Michael obtains a 30/8 balloon mortgage to finance $425,500 at 6.55%. How much principal and interest will he have already paid

STALIN [3.7K]

Answer:

$259 532

Step-by-step explanation:

Step 1. Calculate the monthly payments on a 30-year loan.

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate

of r % is

$P = A(\frac{r}{1-(1+r)^{-n}})$

Data:

We must express the interest rate on a monthly basis.

i = 6.55 %/yr = 0.545 83 %/mo = 0.005 4583

A = $425 500

n = 360 mo

Calculation:

$P = 425 500(\frac{0.005 4853}{1-(1+0.005 4583)^{-360}})$

$P = \frac{2332.22}{{1- {1.005 4583}}^{-360}}$

$P = \frac{2332.52}{1 – 0.140907}$

$P = \frac{2332.52}{0.859 093}$

P = $2703.46

B. Total Payment (T) after 8 years

T = nP

T = 96 × 2703.46

T = $259 532

Michael will have paid $259 532 at the end of eight years.

Angle measurements of the triangle from least to greatest:

35,40,105

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

So we know that 40+3x+x=180.

First step is to combine the like terms on the left hand side:

40+4x=180

Second step is to subtract 40 on both sides.

4x=140

Third step is to divide both sides by 4:

x=35

The angle that is given is the one that is 40 degrees.

So the angle whose measurement is x is really 35 degrees.

The angle whose measurement is 3x is real 3(35)=105 degrees.

In order from least to greatest we have:

35,40,105

Write an inequality the sum of 1 and x is less than 5. 3 is less than y minus 2

bagirrra123 [75]

If an expression has an equal to sign, it is called an equation.

If it has less than or greater than sign, then it is called inequality.

It is also an inequality if it has greater than or equal to or less than or equal to signs. ( ≥, ≤)

The sum of 1 & x is x+1

This sum is less than 5

So we have

x + 1 < 5

Now y minus 2 means

y - 2

Now it says 3 is less than (y-2)

So we get

3 < y - 2

the sum of 1 and x is less than 5 => x + 1 < 5

3 is less than y minus 2 => 3 < y - 2

In the figure below, \overline{AD} AD start overline, A, D, end overline and \overline{BE} BE start overline, B, E, end overline

Troyanec [42]

Answer:

The measure of the arc CD = 64°

Step-by-step explanation:

The rest of the question is the attached figure.

It is required to find the measure of the arc CD in degrees.

as shown at the graph

BE and AD are are diameters of circle P

And ∠APE is a right angle ⇒ ∠APE = 90°

∠APE and ∠BPE are supplementary angles

So, ∠APE + ∠BPE = 180°

∠BPE + 90 = 180°

∴ ∠BPE = 180 -90 = 90° ⇒(1)

But it is given: ∠BPE = (33k-9)° ⇒(2)

From (1) and (2)

∴ 33k - 9 = 90

∴ 33k = 90 + 9 = 99

∴ k = 99/33 = 3

The measure of the arc CD = ∠CPD = 20k + 4

By substitution with k

∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°
