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
=500
Answer:
$81
Step-by-step explanation:
9/2 = 4.5
4.5 x 18 = 81
Answer:
y-1=0
Step-by-step explanation:
To rewrite the equation 5x - 8y + 3 = 5x - 7y + 2, combine like terms across the equal sign using inverse operations.
5x - 8y + 3 = 5x - 7y + 2
5x - 5x - 8y + 3 = 5x - 5x -7y + 2
-8y + 3 = -7y + 2
-y +3 = 2
-y = -1
y- 1 = 0
Answer:
C= 15
Step-by-step explanation:
subtracting 32 from both sides
Dividing both sides by 9/ 5
Answer:
Step-by-step explanation:
x=5c, c=3.14d
x=5(3.14)d
d=x/15.7, x=43.18ft
d=43.18/15.7
d=2.75ft
