A rectangular turtle aquarium is 6 ft long by 4 ft wide. The aquarium is enlarged by increasing
My name is Ann [436]

Answer:

8ft x 6ft

Step-by-step explanation:

For this problem, we want to create measurements of length and width that double our current area.  First we need to find the current area.

C_Length = 6 ft

C_Width = 4 ft

C_Area = C_Length * C_Width

C_Area = 6 ft * 4 ft = 24 ft^2

Now we want our new area to be double the old area.

N_Area = 2C_Area

N_Area = 2 * 24 ft^2

N_Area = 48 ft^2

Now we simply need to find the increase in width and length, distributed equally, that will create the new area.

N_Area = (C_Length + x) * (C_Width + x)

Where x is the amount that each variable is increased by to create the new area.

Now we simply solve for x.

N_Area = (C_Length + x) * (C_Width + x)

48 = (6 + x) * (4 + x)

48 = 24 + 10x + x^2

0 = -24 + 10x + x^2

Now we can either apply the quadratic formula or attempt to factor using the constant break down method.

(x + 12) (x - 2) = 0

x = -12; x = 2

Note that we will choose x = 2 since the other option would require us to have negative material, which is impossible.

Now we can check to validate our answer by plugging in the value of x.

48 ?= (6 + 2) * (4 + 2)

48 ?= (8) * (6)

48 == 48

Thus, we have found the dimensions of the new aquarium, 8ft x 6ft.

Cheers.

The polynomial –16t2 + vt + h0 models the height, in feet, of a ball t seconds after it is thrown. In this polynomial, v represe
MAVERICK [17]
Well if the equation is -16t^2 + vt + h0,

and we know v = 30, because that's the velocity,

and we also know h0 = 6 because that's the height,

then the equation will read: -16t^2 + 30t + 6

Need help in 17 again
dolphi86 [110]

When you divide a whole number by something, you're asking:

                     "How many times can I put this thing
                      into the whole number ?"

If the thing is ' 1 ', then each time you put it into the whole number,
it takes up the space of ' 1 ', and you can do that exactly the same
whole number of times.

If the thing is more than ' 1 ', then each time you stuff it into the
whole number, it takes up the space of more than ' 1 ', so you
can't do that as many times as the whole number.

If the thing is less than ' 1 ', then each time you stuff it into the
whole number, it only takes up the space of less than ' 1 ', so
there'll be enough space in there to let you do that more than
the whole number of times.
______________________________________

Another way to look at it:

When you divide a whole number by something, you're asking:

                 "How many times can I take this thing away from
                  the whole number?"

If the thing is ' 1 ', then each time you take it away from the
whole number, you take away exactly ' 1 ', and you can do that
exactly the same number of times as the whole number.

If the thing is more than ' 1 ', then each time you take it away from
the whole number, you take away more than ' 1 ', so you can't do
that as many times as the whole number.

If the thing is less than ' 1 ', then each time you you take it away
from the whole number, you only take away a piece of ' 1 ', so
you can do that more times than the whole number.
