I would say direct because the more gallons of gasoline used, the bigger the cost.

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

Anarel [89]

<u><em>Answer:</em></u>

D. 272 poles

<u><em>Explanation:</em></u>

<u>We are given that:</u>

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

<u>We can note that</u> each layer has 4 poles more that the one above it

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

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

<u>This is done as follows:</u>

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

Total number of poles = 272 poles

Hope this helps :)

Is this correct? If not please tell the correct answer and how u got it

ICE Princess25 [194]

Answer:

Its incorrect

Step-by-step explanation:

Area is width times height but in this case its 3 numbers so after you did width time height if I'm not mistaken you multiply that number by 4 so you were supposed to multiply 5 and 6 the answer is 30 and then multiply 30 by 4 which is 120 I think.

To complete bookshelves, a customer at your store needs to purchase vertical brackets to attach to the wall. The customer wants

stiks02 [169]

We are given with
height = 9 feet
length = 10 feet
wall brackets:
48-in costing $12.95
60-in costing $16.95
distance of brackets from ends = 1 foot
maximum distance between brackets= 24 inches

The brackets are
48/12 = 4 feet
and
60/12 = 5 feet

One of each must be used to cover the height of the shelf

The length of the shelf is
60 inch
subtracting 1 in from each side for the allowance
60 - 2 = 58 in
Dividing by 24 inches
58/24 = 2.41 ~ 3

The total cost is
($12.95 + <span>$16.95) * 3 = $89.7
The total cost of the brackets is </span>$89.7
