Answer:
Step-by-step explanation:
Area of a triangle = 1/2 * Base * height | Plug in values
82.5 = 1/2 * 15 * height | Multiple both sides by 2
165 inches = 15 * height | Divide both sides by 15
Height = 165/15 = 11 inches
Answer:
36, 45
Step-by-step explanation:
Using equations you get 
because one number is 9 more than the other and the sum is 81. Simplifying you get, 
. Divide both sides by 2 to get 
. Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.
The interest for each method will be:
- Previous Balance Method = $37.50
- Adjusted Balance Method = $36.88
- Average Daily Balance Method = $2966.67
<h3>How to calculate the interest?</h3>
The Previous Balance Method will be:
= PTR
= 3000 × (1/12) × 0.15
= $37.50
The Adjusted Balance Method will be:
P = 3000 - 50 = 2950
t = 1/12
r = 15% = 0.15
I = 2950 × (1/12) × 0.15
= $36.88
The Average Daily Balance Method will be:
= (3000 × 10) +(2950 × 20)/30
= 89000/30
= $2966.67
