Answer:
7.405882353 years
Step-by-step explanation:
Simple interest is
A = P(1+rt)
Where A is the amount in the account
P is the principle invested
r is the rate and
t is the time
6593.75 = 5000( 1+ .0425*t)
Divide each side by 5000
6593.75/5000 = ( 1+ .0425*t)
1.31475 = ( 1+ .0425*t)
Subtract 1 from each side
.31475 = .0425t
Divide each side by.0425
.31475/.0425 = .0425t/.0425
7.405882353 = t
time =31.029 close to 31
A=PRT ( A: amounted investment, p is the investment, R is the rate, T is the time)
rate=%4.25=0.0425
6593.75=5000*0.0425
t=6593.75/(5000*0.0425)
t=31 ( month or weeks the question did not mention the period of time)
C. 155.5 cm2
area = 5*15 + (15+8)*7/2 = 75 + 80.5 = 155.5 cm2
Rule:
