Answer:

0.328\ l

Step-by-step explanation:

Remember that

1\ l=1,000\ cm^{3}

step 1

Find the volume of the aquarium

The volume is equal to

V=b^{3}

we have

b=12\ cm

substitute

V=(12)^{3}=1,728\ cm^{3}

step 2

Convert to liters

1,728\ cm^{3}=1,728/1,000=1.728\ l

step 3

Calculate how much more water is needed to fill the aquarium completely

Find the difference between the volume of the aquarium and the water that contains the aquarium

1.728\ l-1.40\ l=0.328\ l

Burka [1]
Let's assign three blanks for each digit of the unknown number. But let's fill in the tens digit because it is already specified.

_ 4 _

The last digit should be even to make it even. The possible digits for this are 2, 4, 6, and 8. The first digit could be any digit from 1 to 9. Therefore, the possible answers are 

142  242  342  442  542  642  742  842  942
144  244  344  444  544  644  744  844  944

3. Given AB with coordinates A(-4,5) and B(12,13). Find the horizontal distance and the vertical
SCORPION-xisa [38]

The required distance would be 17.88 units coordinates A(-4,5) and B(12,13) and the horizontal distance is 16 units and the vertical distance is 8 units from A to B which are determined by the graphing method.

<h3>What is the distance between two points?</h3>

The distance between two points is defined as the length of the line segment between two places representing their distance.

Given AB with coordinates A(-4,5) and B(12,13).

The formula of the distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: d (A, B) = √ (x₂ – x₁)² + (y₂ – y₁) ².

x₁ = -4, y₁ = 5

x₂ = 12, y₂ = 13

distance = √ (12 – (-4))² + (13 – 5)²

distance = √ (12 + 4)² + (8)²

distance = √ (16)² + (8)²

distance = √ (256 + 64)

distance = √320

distance = 17.88 units

The horizontal distance is 16 units and the vertical distance is 8 units from A to B which are determined by the graphing method.

A quadratic always has two solutions. They could be two real number solutions (the parabola crosses the x-axis in two places), one real number double solution (the parabola just touches the x-axis in one spot) to two complex (imaginary) solutions where the parabola doesn't cross the x-axis.

Mazyrski [523]

Answer: 500+5x=800

Step-by-step explanation:

Given: The rent of waterslide per day  = $500

Let x be the a charge per hour of use.

The number of hours bounce house was used  = 5 hours

Since, the total charge was $800.

Therefore, the equation can be used to find the charge x, in dollars, per hour of use is given by :-

Fixed charge+5 times x=Total charge

\Rightarrow500+5x=800
