Rosetta listed her assets and liabilities on a personal balance sheet.
avanturin [10]

Answer:

$50,000

Step-by-step explanation:

The computation of the amount received after paying off the mortgage is shown below

= Value of the house - mortgage amount

= $150,000 - $100,000

= $50,000

By deducting the mortgage amount from the value of the house we can get the amount received and the same is shown in the computation part

Since in the question it is given that the Rosetta sells her house and paid off mortgage so only these two items are considered and others are to be ignored

Freshman geometry!!! number for please help!!
BARSIC [14]

Option C:

The perimeter of the rhombus is 100 inches.

Solution:

AC = 30 inches, BD = 40 inches

In rhombus, diagonals bisect each other at right angles.

AE = CE = 15 inches

BE = ED = 20 inches

In ΔAED, ∠E = 90°

Using Pythagorean theorem,

AD^2=AE^2 +ED^2

AD^2=15^2 +20^2

AD^2=225+400

AD^2=625

AD^2=25^2

Taking square root on both sides, we get

AD = 25 inches

In rhombus, all sides are equal in length.

AD = DC = CB = BA = 25 inches.

Perimeter = AD + DC + CB + BA

                 = 25 + 25 + 25 + 25

                 = 100 inches

The perimeter of the rhombus is 100 inches.

Option C is the correct answer.
