Step-by-step explanation:
Number of nickels = $1 * 1 nickel/$0.05 = 20 nickels
Thickness of 20 nickels = 20 nickels * 1.95 mm = 39 mm
Let's do the same for the quarters. Each quarter is worth $0.25.
Number of quarters = $1 * 1 quarter/$0.25 = 4 quarters
Thickness of 4 quarters = 4 quarters * 1.75 mm = 7 mm
Find the ratio of the two:
39 mm/7 mm = 5.57
Answer:
$248.75
Step-by-step explanation:
We are told that the interest rate is 13% per Annum = 13% per year
Hence, the interest rate in a month = 13% /12
= 1.0833333333% in a month
Tony Giacomin deposited $1600 on July 3rd in a special investment account which earns 13% p.A. Simple interest.
Interest = Principal × rate × time
Rate = 13% = 0.13
Time = July 3rd - November 12 = 132 days
= $1600 × 0.13 × 132/365
= $75.221917808
On August 17th he deposited another $5600 in the account. If he closed the account on November 12th
Interest = Principal × rate × time
Rate = 13% = 0.13
Time = August 17th - November 12 = 87 days
= $5600 × 0.13 × 87/365
= $173.52328767123288
The next step would be to add these Interests together
$173.52328767123288 + $75.221917808
= $248.74520548
Approximately ≈ $248.75
Therefore, his investment that he has earned over this period of time is $248.75

Answer:
No..
Step-by-step explanation:
=> 7(2n+3) and 14n +3
(lets solve 7(2n+3) = 14n+3)
=> 7(2n+3)
=> (7×2n)+(7×3)
=> 14n + 21
•°• 7(2n+3) not equal to 14n +3
