NEED ANSWER ASAP- FOR FINALS

Answer:

Height: 6 feet, Length: 14 feet, Width: 35 feet.

Step-by-step explanation:

The volume of a rectangular prism is length * width * height.

We know that the height of the pool is 6 feet and that one side is 2.5 times longer than the other. It doesn't matter which side, as long it's not the height. So let's just say the width is 2.5 times bigger than the length.

That means our equation can be rewritten as V = height * length* 2.5 * length.

Plugging in what we know, we get:

2940=(6)(l)(2.5l)\\196=l^{2} \\l=14 feet

Now we need to find the width.

w=2.5l\\w=2.5(14)\\w= 35feet

Answer:

All you have to do is subtract 999 from both sides of the equation.

999 + k = 1,721

k = 722

The answer is C.) k = 722

Hope this helps you!

The 80th term of an arithmetic sequence is twice the 30th term. If the first term of the sequence is 7, what is the 40th term?
VikaD [51]
It seems that "d" or the common difference is a number that makes the sequence go into the larger positive realm of numbers. Therefore, 2*(7+30d)=7+80d. d=35/100. Now just do 7 + 40(35/100) = 21. 21 is your answer!

Alguien me ayuda a desplegar -9x+3=5 por favor
Sidana [21]

Answer:

x=-\frac{2}{9}

Step-by-step explanation:

Supongo que te refieres a ''despejar'' la variable.

-9x+3=5

Primero, aisla los terminos independientes en la derecha y los que tienen variables, en la izquierda. En este caso, el 3 es independiente y no está en la derecha. Para poder moverlo, debo hacer la operación contraria. Por ejemplo, está siendo sumado, para ponerlo del otro lado, lo voy a restar.

-9x+3-3=5-3

Resuelvo;

-9x=2

Ahora, tengo un -9 multiplicándome la variable x, para poder deshacer esta multiplicación y dejar la variable sola, debo hacer la operación contraria; es decir, dividir por -9.

\frac{-9x}{-9}=\frac{2}{-9}

Resuelvo;

x=-\frac{2}{9}

Y, si ya no se puede seguir, este sería mi resultado.

Para comprobar si es correcto, reemplazo en la ecuación original por el valor que ya he encontrado y las respuestas deben ser iguales.

-9x+3=5\\-9(-\frac{2}{9})+3=5\\ 2+3=5\\5=5
