Can someone really help me please!!

Answer:

x=15.5

Step-by-step explanation:

2x+1=32

2x=32-1

2x=31

x=15.5

Answer:

x = [tex]\frac{31}{2}[/tex]

Step-by-step explanation:

Given

2x + 1 = 32 ( subtract 1 from both sides )

2x = 31 ( divide both sides by 2 )

x = [tex]\frac{31}{2}[/tex]

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:

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:

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: quadratic

which quadratic equation best models the data in the graph?

ANSWER: y=0.433x^2

The function that models here is quadratic.

We know,

The curve-shaped graph of a quadratic function is known as a parabola. The vertex of a parabola is one of its focal points. On the graph, it is either the highest or lowest point.

As, The graph shows that the value of x and value of y both increase.

Also, the value of y increases almost as the value of x.

Here the graph represent the Quadratic Equation.

Answer:

x=7/2

Step-by-step explanation:

Answer:

x=7/2

Step-by-step explanation:

x-(2x+1)=8-(3x+2)

x-2x-1=8-3x-2

-x-1=6-3x

+x on both sides

-1=6-2x

-6 on both sides

-7=-2x

7=2x

÷2 on both sides

7/2=x

Answer:

B

Step-by-step explanation:

Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.

8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.

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}

24.000litros

4.000litros

=

I think I understand what you mean. If Alex got $50 and already spent 22 to get into the actual game, then they would have $28 after getting into the actual game.

So $28 dollars.

(Hope that's what you meant.)  

Answer:

The answer is above the solid line.

Step-by-step explanation:

Step-by-step explanation:

If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.

1. 40-22=18

2.18/40=.45

3.45=45%
