In this problem it is asking how many gallons the pool holds. It gives you a method of exchange from cubic feet to this however, so in order to solve for this, we first have to solve for how many cubic feet is in the swimming pool, or how much volume the swimming pool has. The formula for the volume of a rectangle is Length*Width*Depth=Volume. Plugging in what we have we get 30*20*6=Volume, or Volume = 3600. As there are 7.5 gallons of water in each cubic foot, we simply multiply 7.5 times 3600 to get the answer. This is 27000.

bianca and nick are both musicians who sell their songs online.During the same year,bianca sold 8×10 to the power of 3 downloads
Elza [17]
I think for this item we lack or missed out to include in the given the number of songs that Nick sold during that same year. However to determine the number of times that the number of songs that Nick sold than that of Bianca, we just have to divide the number of songs that Nick sold by the number of songs that Bianca did.

What is the equation of a hyperbola with a = 5 and c = 15? Assume that the transverse axis is horizontal.
gogolik [260]

Answer:

\frac{x^2}{25} -\frac{y^2}{200} =1

Step-by-step explanation:

Recall that the equation of  hyperbola centered at the origin with transverse horizontal axis has the general form:

\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}

since we know that a = 5 ,and c = 15,we can solve for b:

15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\

then the equation of the hyperbola becomes:

\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1
