Answer:

80/140 = (80:20)/(140:20) = 4/7

4/7 = (4*4)/(7*4) = 16/28

4/7 = (4*5)/(7*5) = 20/35 not 20/28 not 20/32

4/7 = (4*5.5)/(7*5.5) = 22/38.5 not 22/37

Answer:

$1015.67

Step-by-step explanation:

The appropriate formula for the payment amount (A) for principal P and interest rate r over time period t years is ...

A = P·(r/12)/(1 -(1 +r/12)^(-12t))

Filling in the given numbers, you get ...

A = 176,900·(.0482/12)/(1 -(1 +0.0482/12)^-300) ≈ 1015.67

Violet's monthly payment for principal and interest is $1015.67.

How do you know what angle degree goes on each corner?

Dahasolnce [82]

Let'sSo, we gave 2 parallel lines and 2 transversals, we have to match the angles.

Let's start with angle b,

$\begin{gathered} b+65=180\text{ (angles in a straight line)} \\ b=180-65 \\ b=115^o \end{gathered}$

Let's move on to angle e,

$\begin{gathered} e=b\text{ (Vertically opposite angles)} \\ \text{but b = 115}^o \\ e=115^o^{} \end{gathered}$

Let's move on to angle d,

$d=110^o\text{ (V}ertically\text{ opposite angles)}$

Moving to angle c, we have;

$c=45^o\text{ (Vertically opposite angles)}$

And, angle a;

$\begin{gathered} a=b\text{ (Alternate angles)} \\ a=115^o \end{gathered}$
