Find all the factors of 32, as they come in pairs.
The pairs will give you how many rows you can have, as well as the number of stamps in each row.
1x32 would be 1 row, 32 stamps each
2x16 would be 2 rows, 16 stamps each.
4x8 would be 4 rows, 8 stamps each.
Once you reach the point that it flips around, you can count up all those ways as well.
8x4 is 8 rows with 4 stamps each
16x2 is 16 rows with 2 stamps each
32x1 is 32 rows with 1 stamp each
The total number of factor pairs is 6, meaning he can display the stamps in 6 different ways that follow his want of having the same number of stamps in each row.
The answer would be 49 + 42b if you multiply 7*7 and 7*6b
Answer: <em>time = 55.48 years</em>
Explanation:
Given:
Principal amount = $10000
Interest rate = 2% p.a
Amount = $30000
We can evaluate the time taken using the following formula:


Solving the above equation, we get

Now taking log on both sides, we get;

<em>time = 55.48 years</em>
Answer:

Step-by-step explanation:
Let x be the number of miles Jan can drive in a taxi.
The cost of this ride consists of
- $5.00 flat rate
- $.065 per mile
So, per x miles Jan will pay $0.65x and the total cost of the ride will be
$5.00+$0.65x
Jan has no more than $20 to spend on a ride, then the total cost of his ride must be less or equal to $20. Mathematically, you can write this as
