There are 12 inches in 1 foot, so in 25 feet there are then 25(12) inches, or 300 inches.

now, we know that 300 inches then, is 6 bucks, how much is it for 1 only?

\bf \begin{array}{ccll}
inches&\$\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
300&6\\
1&x
\end{array}\implies \cfrac{300}{1}=\cfrac{6}{x}\implies x=\cfrac{1\cdot 6}{300}\impliedby 2~pennies

12 in = 1 ft
25 ft cost $6
25 × 12 = 300
6 ÷ 300 = 0.02
Each inch costs 2 cents

When a number is raised to a power it is multiplied by itself so the number gets larger. Because the answer is a fraction, this means the power is a negative value.

Find the number 5 has to be raised to be 125 and then make is negative:

5 x 5 x 5 =125

Five-sixths of the boats in the marina are white, 2 5 of the remaining boats are blue, and the rest are red. If there are 12 red
Inga [223]

Answer: There are 120 boats in the marina.

Step-by-step explanation:

Let's suppose that there are N boats

We know that 5/6 of them are white, then we have: (5/6)*N white boats.

The remaining is: N - (5/6)*N = (1/6)*N

We know that 2/5 of the remaining are blue, then we have:

(2/5)*(1/6)*N blue boats

And the rest are red, the rest is:

(1/6)*N - (2/5)*(1/6)*N = (3/5)*(1/6)*N

Then we have (3/5)*(1/6)*N red boats.

And we know that there are 12 red boats, then:

(3/5)*(1/6)*N = 12

Now we can solve this for N, which is the total number of boats in the marina.

N = 12*(6)*(5/3) = 120

There are 120 boats in the marina.

Need help I u get it right I’ll mark u as branniest
Luda [366]

Answer:

primero debemos resolver la ecuacion  sumamos 3d mas 10d luego pasamos el mumero 8 al otro lado entonces se convertira en negativo 8 el resulatdo de esta ecuacion sera 13d elevado al cubo =-8

13d^{3}=-8 entonces

entonces remplazamos en la formula cuadratica 3d=a  0=b  -8=c y lo rremplazas en la formula cuadratica

Step-by-step explanation:

First we must solve the equation we add 3d plus 10d then we pass the number 8 to the other side then it will become negative 8 the result of this equation will be 13d cubed = -8

13d 3 = - 8 then

then we replace in the quadratic formula 3d = a 0 = b -8 = c and you replace it in the quadratic formula
