Answer:
.
Step-by-step explanation:
Two angles are supplements of one another if their sum is
.
Two angles are complements of one another if their sum is
.
Let
be the measure of the angle in question.
The supplement of this angle would be
.
The complement of this angle would be
.
According to the question:
.
Solve this equation for
:
.
Thus, this angle would measure should
.
The supplement of this angle would measure
. The complement of this angle would measure
.
Three times the complement of this angle would be
, which is indeed
greater than the supplement of this angle.
Answer:
<em>Correct choice: C. $320</em>
Step-by-step explanation:
<u>Simple Interest</u>
Definition: Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Marving is saving money in a savings account with a simple interest rate of r=7.5%=0.075. It's known that after t=12 years, the account had earned $288 interest. Substituting in the formula:
288 = P*0.075*12
Calculating:
288 = 0.9P
Dividing by 0.9:
P = $320
Correct choice: C. $320
