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.

Solve the system of equations using subtraction. 2x-4y= -12 2x+y=8 plz help
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

What is the area of the following circle?
r = 4
Answer:
The area of this circle is 50.27
Step-by-step explanation:
The area of this circle is 50.3 units² or 16π
What is incircle?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:
it would be (10)- (4)
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.
What is diameter?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.

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

Which statement is true?
A.
The situation can be modeled by an exponential decay function with a percent change of -10%.
B.
The situation can be modeled by an exponential growth function with a percent change of 11%.
C.
The situation can be modeled by an exponential decay function with a percent change of -11%.
D.
The situation can be modeled by an exponential growth function with a percent change of 10%.
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?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.

Resolver las siguientes inecuaciones cuadráticas y presentar el conjunto solución en forma de intervalo y gráficamente. 1) X2 < 10 – 3x 2) 2x2 + 3x ≥ 2
Respuesta:
1) (-5,2)
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.
