Using the simple interest formula, the interest paid for the loan of $7890 at 11.5% for a term of 5 years will be:
S.I=(PRT)/100
S.I=(7890×11.5×5)/100
=$4536.75
To find the length of the missing side, subtract all of the known side from the perimeter.
14 + 19 + 25 = 58.
73 - 58 = 15.
The fourth side is 15 feet
I hope that helps!
Answer:
He needs to work for a minimum of 4 weeks
Step-by-step explanation:
Amount he has saved=$375
Amount he needs to earns to buy a dirt bike=He earns $155 per week=155×Number of weeks he's worked(N)
This can be expressed as;
The total amount he earns=(Amount saved)+(Amount he earns per week)
Where;
Amount he needs to earn to buy a dirt bike=$900
Amount saved=$375
Amount he earns per week=155N
Replacing in the expression above
900=375+155N
900-375=155N
525/155=155N/155
N=3.4 weeks
Number of weeks=N=3.4 weeks
Minimum Number of weeks he needs to work=4 weeks
