A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.
Alecsey [184]

Monthly payment is $1082.84.

Solution:

Given data:

Principal = $195000

Rate per year = 5.3\% =\frac{5.3}{100}=0.053

Rate per month = \frac{0.053}{12} =0.004416

Time = 30 × 12 = 360 month

<u>To find the monthly payment using formula:</u>

$\text{Monthly payment}=P\times\frac{r(1+r)^n}{(1+r)^n-1}

                           $=195000\times\frac{0.004416(1+0.004416)^{360}}{(1+0.004416)^{360}-1}

                           $=195000\times\frac{0.004416(1.004416)^{360}}{(1.004416)^{360}-1}

If you simplify this using calculator, we get

                           =1082.84

Monthly payment = $1082.84

Option C is the correct answer.

Hence monthly payment is $1082.84.

55) Louis started a simple interest savings account with $1500 that earned 3.5% interest. He left the account untouched until so
ASHA 777 [7]

Answer:

  3.5 years

Step-by-step explanation:

Each year, Louis earned

  $1500×0.035 = $52.50

in interest.

The amount of interest that had been credited to his account at the time of withdrawal was ...

  $1683.75 -1500.00 = $183.75

Then the length of time the money had been in the account was ...

  $183.75/($52.50/yr) = 3.5 yr

_____

<em>Comment on the problem</em>

We have assumed the account earned simple interest. Given the neatness of the answer, we believe that to be a correct assumption.

If 50 people can fit into 6 rooms. How many people<br> fit into 42 rooms?
fiasKO [112]

Answer:

350 people can fit into 42 rooms

Step-by-step explanation:

So we can write it as a relation fraction equation:

\frac{50}{6}=\frac{x}{42}

Where:

x represents the people can fit in 42 rooms

x=\frac{50*42}{6}

x=350

Therefore, <u>350 people can fit into 42 rooms.</u>

I hope it helps you!

One of Newton’s laws of motion states that objects in motion tend to stay in motion. What is the reason that this law may not al
Nastasia [14]

The answer is D.

The full specification of Newton's First Law is (from Wikipedia)

In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

On earth we're generally in slightly a non-inertial frame, with rotation and revolution around the sun. It's also impossible to turn of gravity, so objects are being acted upon by an outside force. Typically there's also the outside force of friction, which makes things tend to stop.
