Answer:
Aiden and his sister have 360 quarters together. If Aiden has twice as much as his sister, he has 180 quarters.
360/2 = 180
Aiden divides his quarters into 3 equal piles.
180/3 = 60
Aiden has 60 quarters in each of his 3 piles.
You divide 15 by 15 and you get 1.
Answer: the interest rate is 3.67%
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
I represents interest paid on the bond.
P represents the principal or amount at which you bought the bond.
R represents interest rate on the bond
T represents the duration of the bond in years.
From the information given,
P = 3000
T = 10 years
I = 4100 - 3000 = 1100
Therefore,
1100 = (3000 × R × 10)/100 = 300R
R = 1100/300
R = 3.67%
5(6 - 4v)=v+21
30 - 20v=v+21
30-21=v+20v
9=21v both side divided by 21
9÷21=v
0,428=v
