Answer:

The 99th tower contains 9900 blocks.

Step-by-step explanation:

From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:

n + n²

Now let us use the diagram to validate the idea.

Tower 1:

n = 1

Number of blocks = 1 + 1² = 2

Tower 2:

Number of blocks = 2 + 2² = 6

Tower 3:

Number of blocks = 3 + 3² = 12

Using same idea, we can obtain the number of blocks in the 99th tower as follow:

Tower 99:

n = 99

Number of blocks = 99 + 99² = 9900

Therefore, the 99th tower contains 9900 blocks.

For me being 100% honest:

grade 9-11 no homework, pay attention in class and study night before.

Grade 12: pay attention more in class, do some homework when concepts hard, study night before.

Uni: Read notes, do class homework, read textbook, study week before.

Answer:

105

Step-by-step explanation:

500 goes into 100, 5 times

21 times 5 is 105

So 21/100 is equal to 105/500

Or you can do

500*0.21=105
