ill decides to move her fish from a 20 gallon aquarium to a 50 gallon aquarium. She added 3 tablespoons of salt to her old aquar

klemol [59]

In the old aquarium, 3 tablespoons of salt were used for 20 gallons. That's a conversion ratio of

$\dfrac{3\,\rm tbsp}{20\,\rm{gal}}=0.15\,\dfrac{\rm tbsp}{\rm gal}$

That is, for every gallon of water in the aquarium, there was 0.15 tbsp of salt. So a 50 gallon aquarium, Ill should add

$(50\,\rm{gal})\left(0.15\,\dfrac{\rm tbsp}{\rm gal}\right)=7.5\,\rm{tbsp}$

to maintain the salinity.

Find a Cartesian equation for the curve.

Galina-37 [17]

$r = 3sec( \alpha ) \\ r = \frac{3}{cos( \alpha )}$

$x = rcos( \alpha ) \: \: \: \: \: \: \: cos( \alpha ) = \frac{x}{r}$

$r = \frac{3}{ \frac{x}{r} } \\ r = \frac{3r}{x} \: \: \: \: \: \: x = 3 \\ line$

You mix 1/2 cup of oats for every 1/4 cup of honey to make 12 cups of granola. How much oats and how much honey do you use?

Shalnov [3]

<h2>Answer: </h2>

I will use 6 cups of oats and 1 cup of honey to make 12 cups of granula .

<h3>Explanation: </h3>

Let x be the number of cups of oats and let y be the number of cups of honey. Given statement can be expressed in fractions as

½ x / ¼ y = 12

4x/2y = 12

2x/y = 12

x/y = 12/2 = 6/1

x=6, y=1

Therefore number of cups of oats = x = 6 cups

Number of cups of honey = y = 1 cup
