Answer:

30

Step-by-step explanation:

i believe that the 13 is there to throw you off. anyway to solve just do 5•12=60

60÷2=30 so 30 is area of triangle

area of triangle =1/2×base×height

area of triangle=1/2×12×5

area of triangle=30 unit²

Answer:

Jordan is tracking a recent online purchase. The shipping costs state that the item will be shipped in a 24-inch long box with a volume of 2,880 cubic inches. The width of the box is seven inches less than the height.

The volume of a rectangular prism is found using the formula V = lwh, where l is the length, w is the width, and h is the height.  Complete the equation that models the volume of the box in terms of its height, x, in inches.  24 x2 -  168 x = 2,880

Is it possible for the height of the box to be 15 inches?  

Yes

Answer:

24 x2 -  168x = 2,880, Yes

Answer:

From bottom = 30 cm

Below top = 20 cm

Step-by-step explanation:

Length & breadth of the aquarium = 40cm(as it is square)

Volume of aquarium = l x b x h

volume of aquarium = 40 x 40 x 50 = 80000 cm³

Volume of water = ½ half of aquarium

Volume of water = ½ x 80000 = 40000 cm³

Volume of the solid cube = a³ = (20cm)³ = 8000cm³

Surely, 40000>>>8000, level doesnt reach the top of the tank.

Volume acquired = 40000+8000=48000 cm³

Now, let it has reached reached a height h from the ground(bottom).

Volume = 48000 => lx b x h = 48000

=> 40 x 40 x h = 48000

=> h = 30 cm

The height at which water has reached is 30 cm(from bottom).

Thus, below the top it has reached = total height - 30 cm = 50 - 30 = 20 cm

Answer 870.15

Step-by-step explanation:

Answer:

40 cm^2

Step-by-step explanation:

The area of the polygon is comprised of two triangles, each of which can be broken down into two right triangles for a total of four right triangles when split vertically.

The formula for the area of a triangle is: A = 1/2 * base * height.

The base for both triangles is 8 cm, and the height for both triangles is given on the right (6 cm for the top triangle and 4 cm for the bottom triangle).

The area of the top triangle will be:

A = 1/2 * 8 * 6

A = 4 * 6

A = 24

The area of the bottom triangle will be:

A = 1/2 * 8 * 4

A = 4 * 4

A = 16

Adding the values of the two areas, we get a total area of 40 cm^2.

Answer:

f(x) = A*∛(x + 2) + 3

Step-by-step explanation:

Suppose a generic cube as:

f(x) = A*∛(x - b) + C

We will have a turning point at the x value:

x = b

Then if we have a turning point at (-2, 3)

This means that the turning point is at x = -2 and y = 3

Then b = -2

And our cube root function will be something like:

f(x) = A*∛(x - (-2)) + C

f(x) = A*∛(x + 2) + C

And we know that f(-2) = 3

then:

f(-2) = A*∛(-2 + 2) + C = 3

f(-2) =  A*∛(0) + C = 3

      = C = 3

Then the general equation will be something like:

f(x) = A*∛(x + 2) + 3

Answer:

y= 169 −  [tex]100^{2}[/tex]

Step-by-step explanation:

A parabola is a symmetrical plane curve that forms when a cone intersects with a plane parallel to its side.

Standard form of a quadratic function represent a parabola.

The equation of parabola is [tex]y=-x^{2} +1.69[/tex]

We have to find the formula for the parabola that has x- intercepts  [tex](1.3,0)[/tex] and [tex](-1.3,0)[/tex], and y- intercept [tex](0,1.69)[/tex]

So that, the intercept form of the quadratic equation is;

                    [tex]y=a(x-p)(x-q)[/tex]

where [tex](-1.3,0)=(p,0)[/tex]  and [tex](1.3,0)[/tex] is[tex](q,0)[/tex].

Since, with the vertex being at the y axis and the intercepts at the x axis means that the parabola opens down.

So that,

           [tex]1.69=a(0+1.3)(0-1.3)\\ \\1.69=-1.69 a\\ \\a=-1[/tex]

Substituting value of a in above equation.

           [tex]y=-1(x+1.3)(x-1.3)\\\\y=-1(x^{2}-1.69 )\\\\y=-x^{2} +1.69[/tex]

Hence, the equation of parabola is [tex]y=-x^{2} +1.69[/tex]

Answer:

60

Step-by-step explanation:

If -30 is its only zero, than the factors are (x+30)(x+30) = [tex]x^2 + 60x + 900[/tex]

Than b = 60

The value of b of the function f (x) would be,

⇒ b = 60

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = x² + bx + 900

And, -30 as its only zero.

Now, The value of zero of function is satisfy the function as;

⇒ f (- 30) = 0

⇒ (- 30)² + (- 30)b + 900 = 0

⇒ 900 - 30b + 900 = 0

⇒ 1,800 = 30b

⇒ b = 60

Thus, The value of b of the function f (x) would be,

⇒ b = 60

Step-by-step explanation:

Step-by-step explanation:

Un deposito de riego tiene una capacidad de 24000 litros. Un día se consumen 2/3 del deposito. al día siguiente no se riega y el deposito recupera 1/3 de su capacidad. Al día siguiente se consumen 6000 litros. Si inicialmente el deposito contenía 18000 litros. ¿Que fracción del total queda el ultimo día?

Comenzamos:

El deposito tiene: 18.000 litros

Se consumen 2/3 del depósito: 24.000 * 2/3 = 16.000 litros

Queda: 18.000 - 16.000 = 2.000 litros

Recupera 1/3 de su capacidad: 24.000 * 1/3 = 8.000 litros

Ahora tiene: 8.000 + 2.000 = 10.000 litros

Se consumen 6.000 litros: 10.000 - 6.000 = 4.000 litros

Fracción que representa sobre el total:

\frac{4.000litros}{24.000litros}=\frac{1}{6}
