Which expression is equivalent to 2x^2 +7x+4

Answer:

41.6 m

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length ), then

s² = 108.16 ( take the square root of both sides )

s = [tex]\sqrt{108.16}[/tex] = 10.4

Then

perimeter = 4s = 4 × 10.4 = 41.6 m

Answer:

$679,857.92

Step-by-step explanation:

The computation of the total amount of money would be owed is shown below

A = P × (1 + r)^t

where

A represents the total money owed

P represent the borrowed amount

r represent the rate of interest

t represents the time period

So,

= $150,000 × (1 + 0.06)^15

= $150,000 × 1.06^15

= $679,857.92

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:

45

Step-by-step explanation:

So a triangle adds up to 180 and so does a line.

180-93=87

And because of vertical angle proof, 48 is the other angle of the triangle.

87+48=135

180-135=45

Answer:

x = 45

Step-by-step explanation:

To get to the interior of the triangle from 48 use vertically opposite angles. That means that the two remote interior angles = 93

Put in simpler language

48 = interior angle

93 = x + 48

93 - 48 = x

x = 45

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:

x=21

Step-by-step explanation:

61+34 = 95  

360( a circle) - 95 = 265

265 +7 +22 = 294

9x+5x=14x

294=14x (divide both by 14 to get x)

X=21

Answer:

x = 21

Step-by-step explanation:

A circle makes a 360 degree turn

So the measure of the arcs should add up to equal 360

That being said we create an equation to solve for x

360 = 61 + 5x - 7 + 34 + 9x - 22

Now we solve for x using basic algebra

Step 1 combine like terms

61 - 7 + 34 - 22 = 66

5x + 9x = 14x

now we have 360 = 14x + 66

step 2 subtract 66 from each side

66 - 66 cancels out

360 - 66 = 294

now we have 294 = 14x

step 3 divide each side by 14

294/14=21

14x/14=x

we're left with x = 21

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:

ask the internet this question sorry not being rude its becausd no ones answered it

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

=
