What is th result of converting 20 ounces into pounds?
Harrizon [31]
Hello!

The Correct Answer would be:

"1.25 Pounds"

Why? Well:

1 ounce (oz) is equal to 0.0625 pounds (lb).

1 oz = (1/16) lb = 0.0625 lb

The mass m in pounds (lb) is equal to the mass m in ounces (oz) divided by 16:

m(lb) = m(oz) / 16


So as Result, The Answer is 1.25 Pounds.


Hope this Helps! Have A Wonderful Day! :)

I NEED IT&lt;&lt;&lt; I WILL MAKE YOU THE BRAINLIEST IF YOU CAN HELP ME
erma4kov [3.2K]

Answer:$728

Step-by-step explanation:

$156,000 less 20% is $124,800.

That is the amount that is being financed. If the rate is7% per year the first months interest is:

124,800*.07/12 = $728

You didn't ask but if the mortgage is like most conventional mortgages the 30 * 12 = 360 payments are all approximately equal, with less money expended on paying down the principal at first. Their equal payment would be: $830.30
