Simple Interest Rate Formula:
- A is final amount
- P is principle amount
- r is rate
- t is time
Step-by-step explanation:
<u>Step 1: Define</u>
A = 960
r = 0.12
t = 5
<u>Step 2: Solve for </u><em><u>P</u></em>
- Substitute in variables [Simple Interest Rate Formula]:
- [Interest] (Parenthesis) Add:
- [Interest] Evaluate exponents:
- [Interest] [Division Property of Equality] Isolate <em>P</em>:
- [Interest] Rewrite:
Answer:
31.6 feet by 15.8 feet.
Step-by-step explanation:
Area of a Rectangle = Length X Breadth = LB
The area of the playground is to be 500 square feet
Therefore:
LB=500
Perimeter of the Rectangle = 2(L+B)
The Chain link fence that costs $2 per linear foot on three sides and a fancier wooden fence that costs $6 per linear foot on the fourth side.
Cost = ${2(L+2B)+6L}=2L+4B+6L=8L+4B
Cost= $(8L+4B)
From: LB=500, B=500/L
Substitute B into 8L+4B
C(L) =
C(L)=
The minimum cost of the fencing occurs when the dimensions are minimum.
If we take the derivative of C(L)
At
Recall: B=500/L
The dimensions that minimizes the total cost of the fencing are 31.6 feet by 15.8 feet.
If 19 out of 28 renters keep a pet, there are renters who don't keep a pet.
Whenever you have a subset of some set, and you want to know which percentage of the set the subset represents, you simply have to compute
So, in your case, you're wondering what percentage of 28 does 9 represent. So, the formula becomes
