Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 30000
r = 6% = 6/100 = 0.06
n = 4 because it was compounded 4 times in a year.
t = 10 years
Therefore,.
A = 30000(1 + 0.06/4)^4 × 10
A = 30000(1 + 0.015)^40
A = 30000(1.015)^40
A = $54421
The amount of interest earned after 10 years is
54421 - 30000 = $24421
Answer:
JUST C
Step-by-step explanation:
use the pythagorean theorem
A fraction is a piece of a whole 3/5
a opposite number is like -5 and +5
a reciprocal is the inverse operation -5 and +5 again
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.
4 / 6 = 28 / 42 ;
6 / 7 = 36 / 42 ;
But, 36 > 28 ;
36 / 42 > 28 / 42 ;
6 / 7 > 4 / 6 ;
6 / 7 is larger than 4 / 6 ;
