Jerome opened the account 17 years ago
<em><u>Solution:</u></em>
Jerome deposited $8,000 into a new retirement account with a simple interest rate of 2.8%
Therefore,
Principal = $ 8000
Rate of interest = 2.8 %
The account has earned $3,808 in interest
Simple interest earned = $ 3808
<em><u>The formula for simple interest is given as:</u></em>
Where,
"p" is the principal and "n" is the number of years and "r" is the rate of interest
Substituting the known values,
Thus he opened the account 17 years ago

4. 3x+7=37, 3x=37-7=30 x=30÷3=10
5. 31=7x-11, 7x=31+11=42 x=42÷7=6
6. 11k-84=92, 11k=92+84=176 k=176÷11=16
7. 4r+13=57, 4r=57-13=44 r=44÷4=11
8. z÷4+16=21, z÷4=21-16=5 z=5×4=20

Answer:
75 in³
x: 30
y: 20 35
Step-by-step explanation:
v = πr²h / 3
v = 3.14 * 3² * 8 / 3
v = 3.14 * 9 * 8 / 3
v = 75.36 in³
Rounded
v = 75 in³
