Answer:

b = 17.55

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + b^2 = 18^2

16 + b^2 = 324

<u>-16              -16</u>

b^2 = 308

square root them

<u>b = 17.55</u>

let me know if it is correct!

Calls from a call box are charged per minute at one rate for the five minutes, then a different rate for each additional minute.
nirvana33 [79]

Answer:

  c.  $0.75 per minute at one rate for the first 5 minutes and $0.25 per minute thereafter

Step-by-step explanation:

The last 5 minutes of the 12-minute call cost ...

  $5.50 -4.25 = $1.25

so the per-minute rate at that time is ...

  $1.25/(5 min) = $0.25/min . . . . . . . . matches choice C only

__

You know the answer at this point, but if you want to check the rate for the first 5 minutes, you can subtract 2 minutes from the 7-minute call to find that ...

  The first 5 minutes cost $4.25 - 2·0.25 = $3.75, so are charged at ...

     $3.75/(5 min) = $0.75/min . . . . . . . matches choice C

KIM [24]

Answer:

<em>1885.5 m^3 of water</em>

<em></em>

Step-by-step explanation:

I'll assume this is the complete question

<em>Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the pool. When the pool is filled to this recommended level, approximately how many cubic feet of water will it contain? Use π = 3.14 </em>

<u><em>The pool forms</em></u><em> a cylinder with a radius of 12 feet and a height of 4.5 feet.</em>

<em></em>

height of pool = 4.5 ft

radius of pool12^{2} = 12 ft

height of water is 4 inches below pool top

<em>12 inches make 1 ft</em>

4 inches = 4/12 ft = 0.33 ft

Therefore, height of water = 4.5 - 0.33 = 4.17 ft

<em>volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed</em>

volume of cylinder formed by the water = volume of water = πr^{2}h

volume = 3.14  x 12^{2} x 4.17 = <em>1885.5 m^3 of water</em>
