Answer:
you saved $10.00

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 40 × 25/100

Discount = 40 x 0.25

Answer:

10

Step-by-step explanation:

What is 25% of 40?

Y is 25% of 40

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 25% * 40

Converting percent to decimal:

p = 25%/100 = 0.25

Y = 0.25 * 40

Y = 10

Answer:

Step-by-step explanation:

[tex]12000 \times {1.05}^{4} = 14586[/tex]

Step-by-step explanation:

8x+ 14y= 4

-6×-7y= -10

For elimination method we can decide to eliminate either the y or x variable I'm going to eliminate the x variable so either of the one am eliminating we multiply the first equation by the coefficient of the variable we are eliminating in other words

8x +14y=4.....*-6

-6×-7y= -10......*8

-48x-84y= -24

-48x-56y= 80

then we multiply the second equation all through by -1

-48x-84y= -24

48x+ 56y= -80

28y=-104

y= 26/7

x= 8/3

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position. The coordinates of the point Q are (25,13).

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Let the coordinates of the point Q be represented by Q(a,b).

Given the Ratio from P to Q is 2:3.

The internal division of the line segment using the ratios will be,

PR/RQ = 2/3

3P = 2Q

3(-10, 3) = 2(a, b)

Now, the coordinates of R can be rewritten as,

[tex]R = (\dfrac{-30+2a}{2+3},\ \dfrac{9+2b}{2+3}) = (4,7)[/tex]

Comparing the coordinates,

(-30+2a)/(2+3) = 4

a = 25

(9+2b)/(2+3) = 7

b = 13

Hence, the coordinates of the point Q are (25,13).

Right triangles are triangles with a measure of 90 degrees

The value of x is 76/11

The equation is given as:

sin (3x+5) = cos (8x+9)

To solve for x, we make use of the following theorem

If sin(A) = cos(B), then

A + b = 90

So, we have:

3x + 5 + 8x + 9 = 90

Collect like terms

3x + 8x = 90 - 5 - 9

Evaluate the like terms

11x = 76

Divide both sides by 11

x = 76/11

Hence, the value of x is 76/11

Step-by-step explanation:

we're looking for x which is the opposite in the diagram we've been given the hypotenuse in the question as 1.8

so we use sin = opp/hypotenuse

sin50= x/1.8

x = sin50× 1.8

Chaos theory has a wide range of real-world applications and is used in fields such as weather prediction, finance, and biology.

Chaos theory is a branch of mathematics that studies the behavior of systems that are highly sensitive to initial conditions. The "butterfly effect" is a popular term used to describe the idea that small variations in initial conditions can lead to vastly different outcomes over time. This theory has many real-world applications in various fields.

One of the fields that makes use of chaos theory is weather prediction. Meteorologists use chaos theory to understand how small variations in atmospheric conditions can lead to large-scale weather patterns. They use computer simulations to model how different initial conditions can lead to different weather outcomes. This helps them make more accurate weather predictions and plan for extreme weather events.

Another field that uses chaos theory is finance. Financial analysts use chaos theory to understand how small fluctuations in financial markets can have a significant impact on the economy. They use mathematical models to analyze stock prices and interest rates and determine how small changes can lead to large market movements. This helps them make informed investment decisions and minimize risk.

Chaos theory is also used in biology to study the behavior of populations of animals, plants, and microorganisms. Biologists use chaos theory to understand how small changes in the environment can have a major impact on the growth and survival of populations. This helps them make informed decisions about the conservation and management of natural resources.

In conclusion, chaos theory has a wide range of real-world applications and is used in fields such as weather prediction, finance, and biology. The idea that small variations in initial conditions can lead to vastly different outcomes over time is a powerful tool for understanding complex systems and making informed decisions.

Answer:

There are two ways to do this problem algebraically or trigonometrically.

Algebraically/geometrically

The ratios of the sides of a 30/60/90 tri. are x, x√3, 2x (short leg, long leg, hyp). Therefore, if the long leg is 6 'units'. then 6 = x√3. x = 6√3.

The hyp is 2x then the hypotenuse is 2(6√3) = 12√3, rationalizing is 12√3/3 = 4√3

Using Trig.

We can use sinx = y/r = opp/hyp. The long leg of 6 is opposite 60 degrees (pi/3).

Therefore, sin(pi/3) = 6/r =

r = 6/sin(pi/3) = 6/(√3/2) = 12/√3, when you rationalize you get 12√3/3 = 4√3

The sine and cosine ratios for a 30°–60°–90° triangle with a hypotenuse of 6, when θ = 60° are  6√3 and 4√3.

This is defined as the longest side of a right-angled triangle and is opposite to the right angle.

The ratios of the sides of a 30/60/90 triangle are x, x√3, 2x (short leg, long leg, hyp). We can infer that the long leg is 6 'units' which is

6 = x√3

x = 6√3.

The hypotenuse is 2x then the hypotenuse is 2(6√3)

= 12√3 when rationalized
