STEP 1: Convert interest rate of 2% per 6 months into rate per year.
rate per year = rate per 6 month⋅2=2%⋅2=4%
STEP 2: Convert 9 months into years.
9 months =
9
12
years=0.75 years
STEP 3: Find principal by using the formula
I=P⋅i⋅t
, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example I = $15, i = 4% and t = 0.75 years, so
I
P
P
P
=P⋅i⋅t
=
I
i⋅t
=
15
0.04⋅0.75

Answer:
x = 55 degree
Step-by-step explanation:
let the another angle be y
y+108=125 (sum of two interior opposite angle is equal to the exterioe angle formed)
y=125-108
y=17
y+x+108=180 degree (sum of interior angle of a triangle)
17 + x + 108 =180
x + 125 =180
x = 180-125
x=55
Answer: Option B.
Step-by-step explanation:
Given the polynomial:
Observe that 
and 
are perfect squares. Then, you can rewrite the polynomial in this form:
You can identify that:
Then, we can check if 
Since 
, the polynomial <em>IS NOT </em>a perfect square trinomial of the form 
X=area of the country A
y=area of the country B
we saggest this system of equations:
x+y=178,973
x=y+373
we solve this system of equations by substitution method.
(y+373)+y=178,973
2y=178,973-373
2y=178600
y=178,600/2=89,300
x=y+373
x=89300+373=89,673
answer:
area of the country A=89,673 Km²
area of the country B=89,300 Km²
To check
The combined land area of the countries A and B is =89,673 Km²+89,300 Km²=178,973 Km²
Country A (89,673 Km²) is 373 Km² more larger than country B (89,300 Km²).
89,673 Km²=89,300 Km²+373 Km²
