Answer:

8.1

Step-by-step explanation:

Formula for volume of cube. V = Volume and A = Edge.

[tex]V=a^{3}[/tex]

[tex]a=\sqrt[3]{v}[/tex]

Therefore we have.

[tex]528=a^{3}[/tex]

[tex]a=\sqrt[3]{528}[/tex]

We have to use the cube root function.

The cube root of (n) is the same as (n) raised to the 1/3 power.

n = a number

[tex]a=v^{\frac{1}{3} }[/tex]

So then we have.

[tex]528^{\frac{1}{3} } =a[/tex]

[tex]a=8.08248004[/tex]

Round to 1 decimal place.

[tex]a=8.1[/tex]

Answer:

Step-by-step explanation:

(a - b)² + 4ab = a² + b² - 2ab + 4ab

Combine like terms

                    = a² + b² + 2ab

                    = (a +b)²

                    = (a +b)(a + b)

Step-by-step explanation:

Answer:

55°

Step-by-step explanation:

Let's start by finding "y" (see diagram attached).

Using the given diagram, we can conclude that the angle measuring 125° and angle y are a linear pair or supplementary. This means that they add up to 180°.

We can use this information to set up an equation:

[tex]125^{\circ}+y=180^{\circ}[/tex]

Subtract 125° from both sides:

[tex]y=55^{\circ}[/tex]

The diagram displays two parallel lines cut by a transversal.

Therefore "x" and "y" are corresponding angles.

The corresponding angle theorem states that if the two lines being cut by a transversal are parallel, then corresponding angles must be congruent/equivalent.

Using this theorem we can set up an equation...

[tex]y=x[/tex]

Therefore...

[tex]x=55^{\circ}[/tex]

Answer:

  2a^3 -3a^2 -45a +50

Step-by-step explanation:

The expansion of the product of polynomials is an application of the distributive property. Usually, it needs to be applied several times.

  (2a^2+7a-10)(a-5)

  = 2a^2(a -5) +7a(a -5) -10(a -5)

  = 2a^3 -10a^2 +7a^2 -35a -10a +50

  = 2a^3 -3a^2 -45a +50

[MA]:

48 r 40

The explanation:

94 x 4 = 376

4,552 - 376 = (792 or ?)

94 x 8 = 752

792 - 752 = 40

94 is greater than 40 so we can't add anymore.

Thus, the answer is 48 r 40

Answer:

The smaller number is 23.

The bigger number is 131.

Step-by-step explanation:

"difference" means subtraction. In this question "more than" means adding. This can be done with one variable. And would take more reasoning with the meaning of the words, but less complicated algebra.

If you are learning systems of equations in high school or college, then you may want to use two variables. The set up is way more straight forward. But then you also need strategies to solve a system of equations.

There are two solutions attached. You only need one that matches the math you are studying. see images.

Answer:

Step-by-step explanation:

Ratio = 7 : 5

Numbers are 7x , 5x

[tex]\dfrac{7x-2}{5x-2}=\dfrac{3}{2}\\\\\\[/tex]

Cross multiply,

2*(7x - 2) = 3*(5x -2)

2*7x - 2*2 = 3*5x - 3*2

14x - 4       = 15x - 6    

14x - 4 + 6 = 15x   {Add 6 to both sides}

14x  + 2      = 15x

            2    = 15x - 14x       {Subtract '4x' from both sides}

   x = 2

7x = 7*2 = 14

5x = 5*2 = 10

Numbers are 14 , 10  

Answer: 8/15 + 2/5 = 0.93etc or 14/15

Step-by-step explanation:

Hey there!

2x^2 - 5 / x + 9

= 2(-1)^2 - 5/ -1 + 9
= (2(-1)^2 - 5) / (-1 + 9)

= (2(1) - 5) / 8

= (2 - 5) / 8

= -3 / 8

≈ -0.375

Therefore, your answer is:

-3/8 OR -0.375

EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER!

Good luck on your assignment & enjoy your day!

Answer:

Step-by-step explanation:

a) The area of Australian desert is 3,830,040km²

b)The approximate number of dingos will be  517,055

a) Given the following parameters;

Area of Sahara desert = 9,000,000km²

If the Australian desert is 42.556% of the size of the Sahara desert in Africa, then the area of the Australian desert is expressed as:

Area of Australian desert = 0.42556 * 9,000,000

Area of Australian desert = 3,830,040km²

b) If dingo density is approximately 0.135 animals km² during the dry season, the approximate number of dingos in the Australian desert during this season. will be:

number of dingos =  0.135 * 3,830,040km²

number of dingos = 517,055.4

Hence the approximate number of dingos will be  517,055
