The number of horses occupying stalls at the county fairgrounds can be modeled by the following function, where x represents the

Elenna [48]

Answer:
_______________________________________________________
The rewritten equation is:

" - 3x² + 30 + 225 = 0 " ;

which is ultimately simplified to:

" x² − 10 − 75 = 0 " .
___________________________________________________
The number of days is: "15 days" .
___________________________________________________

Explanation:
______________________________________________
Given:

h(x) = - 3x² + 30 + 225 ;

Rewrite as: " - 3x² + 30 + 225 = 0 " ;
__________________________________________________________
Multiply EACH SIDE of the equation by "-1" ; to get rid of the "-3" ;

-1 * {- 3x² + 30 + 225 = 0} ;

to get: " 3x² − 30 − 225 = 0" ;

Divide EACH SIDE of the equation by "3" ; to simplify; since:

"3", "30", and "225" are divisible by "3" ;

{3x² − 30 − 225} / 3 = 0 / 3 ;

to get:
______________________________________
" x² − 10 − 75 = 0 " ;

______________________________________
Let us factor:

-15 + 5 = -10 ;

-15 * 5 = -75 ;
_______________________________________
Rewrite as:

(x − 15) (x + 5) = 0 ;

x = 15; and x = -5 ;
_______________________________________
The number of days cannot be "negative value"; so we stick with:

"x = 15 days"

The go fish game tank contains 30 fish the probability of catching a purple fish is 1/3 the probability of catching a green fish

timofeeve [1]

Answer:

2/3

Step-by-step explanation:

since they are just two colors of fish inside, since the probability is always 1.. so we have to minus 1/3 from 1,which is 1-1/3=2/3

Exercise

Maurinko [17]

X - nominator
y - denominator

$\frac{3x}{y+12}=\frac{3}{4}\\
\frac{x+7}{3y}=\frac{1}{2}\\\\
3(y+12)=12x\\
2(x+7)=3y\\\\
3y+36=12x\\
2x+14=3y\\\\
2x+14+36=12x\\
10x=50\\
x=5\\\\
3y=2\cdot5+14\\
3y=10+14\\
3y=24\\
y=8\\\\
\frac{x}{y}=\boxed{\frac{5}{8}}$

The difference of two perfect cubes is 386. If the cube root of the smaller of the two numbers is 7, then the cube root of the l

choli [55]

Answer:

9

Step-by-step explanation:

Let the two perfect cubes be x and y where x > y.

According to the given conditions:

${x}^{3} - {y}^{3} = 386...(1) \\ y = 7...(2) \\ plug \: y = 7 \: in \: equation \: (1) \\ {x}^{3} - {7}^{3} = 386 \\ {x}^{3} - 343 = 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 343 + 386 \\ {x}^{3} = 729 \\ x = \sqrt[3]{729} \\ x = 9$

Thus the cube root of the larger number is 9.
