Answer:
A) $157,555
Step-by-step explanation:
The sum of assets is ...
house + 2 cars = $280,000 +5,200 +15,600 = $300,800
The sum of liabilities is ...
mortgage +car loan +credit card +wedding
= $113,545 +9,200 +2,300 +18,200 = $143,245
The family's net worth is the difference between assets and liabilities:
$300,800 -143,245 = $157,555
Solution:
Perimeter is the sum of the figure's sides.
<u>Note that:</u>
- 10 + 10 + 4 + 10 + 4 + 10 + 10 + 30 = Perimeter of figure
<u>Simplify the expression:</u>
- 5(10) + 2(4) + 30 = Perimeter of figure
- => 50 + 8 + 30 = Perimeter of figure
- => 88 cm = Perimeter of figure
Answer:
The correct option is option D
Step-by-step explanation:
The volume of a pyramid is:
V=1/3(B)(H)
Where
B:Base = s^2
H:Height = 2/3s
Then:
V=1/3(B)(H) = 1/3(s^2)(2/3s) = 2/9s^3
The correct option is option D
