Answer:$32


Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.

You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.
aliina [53]

Answer:

  A. 14040 cubic inches

  B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

  V = LWH

__

<h3>A.</h3>

One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.

One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.

The volume of the fish tank is ...

  V = (39 in)(18 in)(20 in) = 14,040 in³

The volume is 14,040 cubic inches.

__

<h3>B.</h3>

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

<em>Additional comment</em>

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

Find the distance between the two points rounding to the nearest tenth (if necessary)
Andrews [41]

Answer:

The answer is

<h2>2.8 units </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,3) and (-1,5)

The distance is

d =  \sqrt{( { - 3 + 1})^{2} +  ({3 - 5})^{2}  }    \\  =  \sqrt{ ({ - 2})^{2} + ( { - 2})^{2}  }  \\  =  \sqrt{4 + 4}  \\  =  \sqrt{8}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 2 \sqrt{2}  \:  \:  \:  \:  \:  \:  \\  = 2.82842

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you

Sami's square yard needs to be fenced to keep her dog, Sophie, home. Her yard is 400 square feet. How much fencing does she need
Aleksandr-060686 [28]
Answer: The answer is 1,600.
Explanation: since her back yard is a square that means it has 4 sides, and her yard is 400 sq ft. So you multiply 400 by 4 which equals 1,600. I haven’t done this in a long time so I’m not positive. But that should be it.
