Answer:

x=8/3

Step-by-step explanation:

3x+4=12

3x =12_4

3x =8

x =8/3

Answer:

Step-by-step explanation:

x  - the smallest angle

3x  - the middle angle

2x   - twice the smallest angle

3·3x   -  3 times the middle angle

twice the measure of the largest angle (the difference of 3 times the middle angle and twice the smallest angle):  3·3x - 2x = 7x

7x÷2 = 3.5x  - the largest angle

The sum of angles in any triangle is 180°, so:

x + 3x + 3.5x = 180°

7.5x = 180°           {divide both sides by 7.5}

x = 24°

small angle:   x = 24°

middle angle:  3x = 3·24° = 72°

large angle:    3.5·24° = 84°

Answer:

[tex]Surface\ area = 6728.3125(pi)\\\\Surface\ area = 21137.6171211[/tex]

Step-by-step explanation:

The lateral surface area of an object is the surface area of the subject excluding the base and the top of the 3-dimensional figure. The surface area of the object is the 2-dimensional space of an object, in essence, if one was going to wrap the object, the amount of material they would need to cover the object. To find the lateral surface area of a cylinder, one must find the circumference of the circle at the top of the cylinder, and then multiply it by the height of the cylinder. The circumference of a circle is the distance around it, the perimeter.

The formula one would use is,

[tex]A_s = (pi)(r^2)(h)[/tex]

Were (pi) represent the value (3.1415...), (r) represent the radius of the base, that is the distance from the center point of the circle on the base, to the outside distance of the circle. The radius of a circle is always half of the diameter. (h) represents the height of the figure.

[tex]A_s = (pi)(r^2)(h)\\\\= (pi)((\frac{3.5}{2})^2))(13)\\\\= (pi)(1.75)^2(13)\\\\= (517.5625)(13)(pi)\\\\=(6728.3125)(pi)\\\\= ~21137.6171211[/tex]

[tex] r(θ)= \frac{1}{32} {v}^{2} sin2θ[/tex]

Step-by-step explanation:

[tex]r(θ)= \frac{1}{16 }v^2 sinθ cosθ. \\ \\ r(θ)= \frac{1}{16 } v^2 \times \frac{2sinθ cosθ}{2} . \\ \\ r(θ)= \frac{1}{16} {v}^{2} \times \frac{1}{2} \times sin2θ \\ \\ r(θ)= \frac{1}{16} \times \frac{1}{2} {v}^{2} sin2θ \\ \\ r(θ)= \frac{1}{32} {v}^{2} sin2θ[/tex]

The given modeled function for a launched rocket is transformed to  [tex]r(\theta)=1/32 v^2 sin2\theta[/tex]

The range of a launched rocket is modeled by the function r(θ)=1/16 v^2 sinθ cosθ. using a double angle to determine identity to rewrite the formula.

Functions are the relationship between sets of values. i.e. y=f(x), for every value of input x there is its existing output in a set of y. x is the independent variable while Y is the dependent variable.

Here, using identity
[tex]sin2\theta=2sin\theta cos\theta[/tex]
We have, [tex]r(\theta)=1/16 v^2 sin\theta cos\theta.[/tex]
multiply by 2 to the numerator and denominator of the right-hand side.
[tex]r(\theta)=1/(16*2) v^2 2sin\theta cos\theta.\\r(\theta)=1/(32) v^2 sin2\theta[/tex]

Thus, the given modeled function for a launched rocket is transformed to  [tex]r(\theta)=1/32 v^2 sin2\theta[/tex]

Given:

The equation is

[tex]2x+3y=0[/tex]

To find:

Whether the equation represents a direct variation. If it does, find the constant of variation.

Solution:

The general equation of direct variation is

[tex]y=kx[/tex]               ...(i)

Where, k is the constant of variation.

The equation of direct variation is always true for (0,0).

The given equation is

[tex]2x+3y=0[/tex]

It can be written as

[tex]3y=-2x[/tex]

[tex]y=-\dfrac{2}{3}x[/tex]           ...(ii)

For x=0,

[tex]y=-\dfrac{2}{3}(0)[/tex]

[tex]y=0[/tex]

The given equation is true for (0,0). So, it represents a direct variation.

On comparing (i) and (ii), we get

[tex]k=-\dfrac{2}{3}[/tex]

Therefore, the constant of variation is [tex]-\dfrac{2}{3}[/tex].

Answer:

X= 3

Y= -2

Has to be negative to be able to equal zero.

Answer:

x = 3

y = -2

Step-by-step explanation:

4x + 5y = 2........i

2x + 3y = 0........ii

Let's start by eliminating x, so we multiply i by 2 and ii by 4

2|4x + 5y = 2

4|2x + 3y = 0

So that we have

8x + 10y = 4..........iii

8x + 12y = 0..........iv

Subtracting iv from III, we have

-2y = 4

y = 4/-2

y = -2

Going ahead and substituting this value of y in eqn i, we have

4x + 5(-2) = 2

4x - 10 = 2

4x = 2 + 10

4x = 12

x = 12/4

x = 3

Answer:

Step-by-step explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger

Step-by-step explanation:

Let x = cost of a hot dog

     y = cost of a cheeseburger

(1)      2x + 4y = 23.5           (2)    5x + y = 18.25    

                                                           y =  18.25 - 5x

        2x +4(18.25 - 5x) = 23.5

         2x + 73 - 20x = 23.5

         -18x + 73 = 23.5

                  -18x = -49.5

                       x = 2.75                       y = 18.25 - 5(2.75)

                                                           y = 18.25 - 13.75

                                                           y = 4.50

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger

Answer:

The length of the diagonal, d is approximately 24.49 cm

Step-by-step explanation:

The question asks to find the length of the interior diagonal of a rectangular prism, also known as a cuboid;

The parameters of the prism are;

The height of the prism = 10 cm

The width of the prism = 10 cm

The length of the prim = 20 cm

The length of the given diagonal of the cuboid is found by Pythagoras's theorem from the height, 'h', of the cuboid and the diagonal of the base of the cuboid

Let 'l' represent the diagonal of the base of the cuboid, we have, by Pythagoras's theorem;

l² = ((20 cm)² + (10 cm)²) = 500 cm²

The length of the diagonal, 'd', by Pythagoras's theorem is given as follows;

d = √(l² + (²10 cm))

By plugging in the known value for 'l² = 500 cm²', we get;

d = √(500 cm² + (²10 cm)) = √(600 cm²) = 10·√6 cm

The length of the diagonal, d = 10·√6 cm ≈ 24.49 cm (by rounding to the nearest hundredth cm)
