Answer:
Step-by-step explanation:
I = PTR/100
Given from the question:
I = $168
R = 7%
T = 8
P = ?
Substituting into the formula , we have
168 = P X 8 X 7 / 100
168 X 100 = 56P
16800 = 56P
Therefore
P = 16800/5
P = 300
Therefore the original amount in the account is $ 300
Answer:
surface area of the cube is 96m² and the volume is 64m³
Step-by-step explanation:
Surface area of the cube = 6x²
x is the side length
Given
x = 4metres
Surface area of the cube = 6(4)²
Surface area of the cube = 6(16)
Surface area of the cube = 96m²
Volume of the cube = x³
Volume of the cube = 4³
Volume of the cube = 64m³
Hence the surface area of the cube is 96m² and the volume is 64m³
Answer:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
Step-by-step explanation:
A = P(1 + r/n)^nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
Answer:
84
Step-by-step explanation:
4 * 2 = 8
8+4 = 12
X -3y = -15
Subtract 'x' from each side:
-3y = -x - 15
Divide each side by -3 :
<em>y = 1/3 x + 5</em>
This is 'slope-intercept' form.
