Hey there!

$\bold{(2\times6)^4}$
$\bold{2\times6=12}$
$\bold{12\times12\times12\times12}$
$\bold{12\times12=144}$
$\bold{144\times144=20,736}$

$\bold{A.\downarrow}$

$\bold{4\times(2\times6)}$
$\bold{2\times6=12}$
$\bold{4\times12=48}$
$\bold{48\neq20,736}$
$\boxed{\bold{incorrect}}$

$\bold{B.\downarrow}$

$\bold{8^4}$
$\bold{8\times8\times8\times8}$

The amount of water inside each of these things is proportional to the volume of the tank the tropical fish tank has a volume of

k0ka [10]

Answer:

1920 gallons of water

Step-by-step explanation:

From the question; the amount of water is proportional to volume of the tank

i.e amount of water = volume of the tank

in a tropical fish;

3000 gallons of water = 12.5 m³ ----- Equation (1)

However, in the measurement of shark tank, we have

length = 20cm = 0.2 meters

width = 4 meters

Height = 10 meters

How many gallons of water can the shark tank hold?

From the measurement of shark tank, we can calculate the volume;

The volume of the tank = Length × width × height

Volume of the tank = 0.2 × 4 × 10 = 8 m³

since, the amount of water is proportional to volume of the tank

y ( Gallons of water ) = 8 m³ -------- Equation (2)

Equating equation 1 and 2; we have:

3000 gallons of water = 12.5 m³

y ( Gallons of water ) = 8 m³

y ( Gallons of water ) × 12.5 m³ = 3000 gallons of water × 8 m³

y ( Gallons of water ) = $\frac{3000 gallons of water * 8 m^3 }{12.5m^3}$

y ( Gallons of water ) = $\frac{24000}{12.5}$

y ( Gallons of water ) = 1920 gallons of water

Thus, the shark tank can hold 1920 gallons of water

Given f(x)=-2x-1, solve for x when f(x)=-7

Svetlanka [38]

Answer:

The answer is -15.

Step-by-step explanation:

1. 2x - 1

2. 2(-7) - 1

3. (-14) - 1

4. -15

By plugging in our x value, we are able to use PEMDAS to multiply 2 and the value of x and then, we subtract 1 from the value we got from step 3 to get -15.
