A set of telephone poles is stacked in a pile, 8 layers high. The top layer consists of 20 telephone

Anarel [89]

Answer:

D. 272 poles

Explanation:

We are given that:

The top layer has 20 poles, the next down one has 24 poles and the third one has 28 poles

We can note that each layer has 4 poles more that the one above it

Based on this, we can get the number of poles in each layer as follows:

Top layer has 20 poles

Second one has 20 + 4 = 24 poles

Third one has 24 + 4 = 28 poles

Fourth one has 28 + 4 = 32 poles

Fifth one has 32 + 4 = 36 poles

Sixth one has 36 + 4 = 40 poles

Seventh one has 40 + 4 = 44 poles

Eighth one has 44 + 4 = 48 poles

Now, we can get the total number of poles by adding the poles in all layers

This is done as follows:

Total number of poles = 20 + 24 + 28 + 32 + 36 + 40 + 44 + 48

Total number of poles = 272 poles

Hope this helps :)

Find the area of the figure

Vikentia [17]

Answer: 20

Step-by-step explanation:

The base square is 4 x 4, which is 16. That part is easy, but the other part needs more thinking.

We have two more visible full squares, which we can add on to our 16, putting it at 18. But that half squares, we have 4 total have squares. We know that 1/2 + 1/2 = 1

So, 1/2 + 1/2 + 1/2 + 1/2 = 2.

We eventually get 16 (original square) + 2 (two other full squares) + 2 (half squares) resutling in 20.
