Answer:

24 ft^2

Step-by-step explanation:

The small aquarium:

1 * 3 * 2 = 6 ft^2

The large aquarium

(1 + 1) * (3 + 2) * (2 + 1)

2 * 5 * 3 = 30 ft^2

Difference between the larger aquarium and the smaller aquarium:

30 - 6, or 24.

This means that the answer to this question is a, 24 ft^2

2) [tex](-\infty,-2]U(\frac{1}{2},\infty)[/tex]

Explicación paso a paso:

1)

[tex]x^{2}<10-3x[/tex]

Para comenzar este problema, debemos moverlo todo al lado izquierdo de la inecuación, por lo que obtenemos:

[tex]x^{2}+3x-10<0[/tex]

Ahora podemos factorizar el lado izquierdo para obtener:

[tex](x+5)(x-2)<0[/tex]

Ahora podemos cambiar el símbolo < por un = para encontrar los valores de x en los cuales la inecuación es igual a cero.

(x+5)(x-2)=0

Y luego despejamos x.

x+5=0

x=-5

y

x-2=0

x=2

Ahora construimos nuestros intervalos posibles.

[tex](-\infty,-5)[/tex]

(-5,2)

y

[tex](2,\infty)[/tex]

Y escogemos algunos valores de prueba. Estos nos ayudarán a determinar si cada intervalo hace que la inecuación sea verdadera o falsa.

[tex](-\infty,-5)[/tex]

Para este intervalo escojamos -6 y evaluemoslo en la inecuación.

(x+5)(x-2)<0

(-6+5)(-6-2)<0

(-1)(-8)<0

8<0

falso, así que este intervalo no es parte de nuestra respuesta.

(-5,2)

para este escojamos x=0 y probémoslo en la inecuación.

(x+5)(x-2)<0

(0+5)(0-2)<0

(5)(-2)<0

-10<0

verdadero, así que este intervalo es parte de nuestra respuesta.

[tex](2,\infty)[/tex]

Para este escojamos 3 y probémoslo en unestra inecuación.

(x+5)(x-2)<0

(3+5)(3-2)<0

(8)(1)<0

8<0

falso, así que este intervalo no es parte de nuestra respuesta.

así que nuestra respuesta es:  (-5,2)

2)

[tex]2x^{2}+3x\geq2[/tex]

Para resolver este problema, comenzamos moviéndolo todo al lado izquierdo de la inecuación.

[tex]2x^{2}+3x-2\geq0[/tex]

Ahora podemos factorizar el lado izquierdo de la inecuación para obtener:

[tex](2x-1)(x+2)\geq0[/tex]

Ahora podemos cambién el símbolo ≥ por un símbolop de = para obtener los valores de x que hacen que la inecuación sea igual a 0.

(2x-1)(x+2)=0

y ahora despejamos x.

2x-1=0

[tex]x=\frac{1}{2}[/tex]

y

x+2=0

x=-2

Ahora construimos nuestros intervalos posible.

[tex](-\infty,-2][/tex]

[tex][-2,\frac{1}{2}][/tex]

y

[tex][\frac{1}{2},\infty)[/tex]

Ahora escogemos los valores de prueba correspondientes.

[tex](-\infty,-2][/tex]

para este, escojamos -3 y probémoslo en la inecuación.

[tex](2x-1)(x+2)\geq0[/tex]

[tex](2(-3)-1)(-3+2)\geq0[/tex]

[tex](-7)(-1)\geq0[/tex]

[tex]7\geq0[/tex]

verdadero, así que este intervalo es parte de nuestra respuesta.

[tex][-2,\frac{1}{2}][/tex]

para este, utilicemos 0 como valor de prueba.

[tex](2x-1)(x+2)\geq0[/tex]

[tex](2(0)-1)(0+2)\geq0[/tex]

[tex](-1)(2)\geq0[/tex]

[tex]-2\geq0[/tex]

falso, así que este intervalo no es parte de nuestra respuesta.

[tex][\frac{1}{2},\infty)[/tex]

para este, utilicemos 1 como valor de prueba.

[tex](2x-1)(x+2)\geq0[/tex]

[tex](2(1)-1)(1+2)\geq0[/tex]

[tex](1)(3)\geq0[/tex]

[tex]3\geq0[/tex]

verdadero, así que este intervalo es parte de nuestra respuesta.

Así que nuestra respuesta es la unión entre los dos intervalos que resultaron verdadero, por lo que nuestra respuesta es:

[tex](-\infty,-2]U[\frac{1}{2},\infty)[/tex]

Step-by-step explanation:

The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.

Diameter is a straight line passing through the centre of a circle or other safe, or the length of first as millimetre centimetre inches and feet.

here, we have,

The expression that represents the volume of the shaded part of the sphere is (4/3)πr³,

where r is the radius of the sphere,

which is 10 feet (1/2 the diameter).

Therefore, the expression for the volume of the shaded part of the sphere is

(4/3)π(10)³,

or 4,188.7902 cubic feet.

Hence, The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.

Answer:

the value of x = -3

Step-by-step explanation:

10 (x-5) = -80

10x - 50 = -80

10x = -30

x = -3

CHECK:

10 ( -3 - 5) = -80

10 (-8) = -80

-80 = -80

Volume without holes = 3 x 6 x 11 = 198 cubic inches.

Calculate volume of one hole:

3.14 x 0.5^2 x 3 = 2.355 cubic inches

There are 3 holes: 3 x 2.355 = 7.065

Subtract volume of the holes from the brick:

198 - 7.065 = 190.935 cubic inches.

Rounded to the nearest tenth: 190.9 cubic inches.

Answer:

190.9 inches^3

Step-by-step explanation:

First of all we have to find the total volume:

V = dimension 1 x dimension 2 x dimension 3

V = 3 x 6 x 11 = 198 inches^3

now we have to find the volume of the cylinders:

V= radius^2 x pi x height = 0.5^2 x 3.14 x 3 = 2.355 inches^3

the cylinders are three so:

V = 2.355 x 3 = 7.065 inches^3

at least we have to subtract this value at the total volume:

V= 198 - 7.065 = 190.935 = 190.9 inches^3

Answer:

x=2, y= 4

Step-by-step explanation:

Equation 1 is 2x-4y = -12

Equation 2 is 2x+y = 8

Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).

Simplifying we get -5y = -20 and y =4

Substituting y =4 into original equation back we get 2x -4(4) =-12

This equals 2x -16 =-12 and 2x = 4 and x =2

Answer:

The area of this circle is 50.27

Step-by-step explanation:

The area of this circle is 50.3 units² or 16π

The incircle is defined as the largest circle that can be made in a triangle and is tangent to each side of the triangle.

The area of the circle is the product of the pie and the square of the radius.

The area of the circle = πr²

We are given that radius of the circle as r = 4.

Then we know that

Area = πr²

Substitute the values r = 4

π = 3.14

Area = 3.14(4)²

Area = 3.14 × 16

Area = 50.3

Answer:

36

Step-by-step explanation:

The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

percentage, a relative value indicating hundredth parts of any quantity.

The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.

The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.

The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.

Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.

r = (18,000/20,000) - 1 = -0.1

So the percent change per year is -10%, which means that statement A is true.

Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
