Answer: 1000 different flags

Step-by-step explanation:

So for the flag there are 10 color options and you need to have 3 different stripes. Where you are able to use a color more than once.

For the first stripe there are 10 options so it can be any of the 10 choices.

For the second option you are able to use any of the 10 colors again so it can be any of the 10 colors.

For the last option for stripe 3 you can pick from ay of the 10 colors so there are 10 color options is could be.

Now that you know the how many choices of color there can be for each stripe you multiple the color choice for each stripe by each other to get the number of combinations for different flags.

colors for stripe 1x  colors for stripe 2x colors for stripe 3= # of different flags

10x10x10=1000

so there can be 1000 different 3 stripe flags that can be made with 10 colors

Answer: - sqrt3/2

Step-by-step explanation:

Applying angle relationships, the value of x in each figure is determined as:

E. x = 8

F. x = 26

I. x = 9

J. x = 4

Using angle relationship based on the angles involved, create an equation in each case, to enable you find the value of x.

E. 27 + 8x - 1 = 90 [the angle relationship is that they are complimentary angles].

Solve for the value of x:

26 + 8x = 90

8x = 90 - 26

8x = 64

x = 8

F. 7x - 44 = 75 + 63 [vertical angles are congruent]

7x = 182

7x/7 = 182/7

x = 26

I. 180 - (5x - 3 + 13x + 4) = 17 [vertical angles are congruent]

180 - (18x + 1) = 17

180 - 18x - 1 = 17

179 - 18x = 17

-18x = 17 - 179

-18x = -162

x = 9

J. 3y + 10 = 5y - 24 [vertical angles are congruent]

Solve for y

3y - 5y = -10 - 24

-2y = -34

y = 17

Find the value of x:

3y + 10 + 9x + 1 + 82 = 180 [angles on a straight line equals 180 degrees]

3y + 9x + 93 = 180

Plug in the value of y

3(17) + 9x + 93 = 180

51 + 9x + 93 = 180

9x + 144 = 180

9x = 180 - 144

9x = 36

x = 4

Speed is generally the change in distance per unit time. (rate of change of distance)

To calculate speed, we will use speed = distance/time.

speed = 360/3

           = 120km/hr

Since, the train is moving with a constant speed the ratio of distance and time will be equal to 120 throughout the journey.

The required equation is g(x) = 10(3)x which is the correct answer would be an option (A).

The graph of g(x) is obtained by stretching the graph of f(x) vertically by a factor of 2.

Since the vertical stretch of a graph multiplies the y-coordinates of each point on the graph by a constant factor, the equation of g(x) must be obtained by multiplying the y-coordinate of each point on the graph of f(x) by 2.

In the given equation f(x) = 5(3)x, the y-coordinate of each point on the graph of f(x) is 5(3)x.

Thus, to stretch the graph of f(x) vertically by a factor of 2, we need to multiply this y-coordinate by 2 to get the y-coordinate of the corresponding point on the graph of g(x). This gives us the following equation for g(x):

⇒ g(x) = 2 × 5(3)x = 10(3)x

Therefore, the required equation is g(x) = 10(3)x.

The length of shorter leg is 15 inches, length of longer leg is 36 inches and the length of hypotenuse is 39 inches.

What is right triangle?

A right triangle, also known as a right-angled triangle, an orthogonal triangle, or formerly a rectangled triangle, is a triangle with one right angle, meaning that its two sides are perpendicular. Trigonometry's foundation is the relationship between the right triangle's sides and other angle.

Let,

x = Longer leg of triangle

y = Shorter leg of triangle

h = Hypotenuse of triangle

Given: The length of the longer leg of a right triangle is 6inches more than twice the length of the shorter leg.

The length of the hypotenuse is 9inches more than twice the length of the shorter leg.

⇒  x = 6 + 2y

    h = 9 + 2y

The given triangle is a right angled triangle.

⇒                                 x^2 + y^2 = h^2

                          (6 + 2y)^2 + y^2 = (9 + 2y)^2

                36 + 24y + 4y^2 + y^2 = 81 + 36y + 4y^2

                          36 + 24y + 5y^2 = 81 + 36y + 4y^2

36 - 81 + 24y - 36y + 5y^2 - 4y^2 = 0

                             -45 - 12y + y^2 = 0

                               y^2 - 12y - 45 = 0

                       y^2 - 15y + 3y - 45 = 0

                        y(y - 15) + 3(y - 15) = 0

                                 (y - 15)(y + 3) = 0

y - 15 = 0,   y + 3 = 0

y = 15,     y = -3

Since the length is not negative.

So, y = 15

Hence,

Shorter leg = 15 inchs

Longer leg = 6 + 2y = 6 + 2(15) = 36 inches

Hypotenuse = 9 + 2y = 9 + 2(15) = 39 inches

Answer:

1/8

Step-by-step explanation:

To simplify the expression √3/√8, we can first simplify the square root terms by finding the prime factorization of each number under the square root. The prime factorization of 3 is 3, and the prime factorization of 8 is 2 * 2 * 2.

We can then rewrite the square root terms as follows:

√3/√8 = √(3) / √(2 * 2 * 2)

Next, we can use the property of square roots that says that the square root of a number is equal to the square root of each of its prime factors. This means that we can rewrite the square root term as follows:

√(3) / √(2 * 2 * 2) = √(3) / √(2) / √(2) / √(2)

Since the square root of a number is the same as the number itself, we can simplify the expression further by removing the square root symbols from the prime numbers 2:

√(3) / √(2) / √(2) / √(2) = √(3) / 2 / 2 / 2

Finally, we can use the rules of division to simplify the expression even further:

√(3) / 2 / 2 / 2 = √(3) / (2 * 2 * 2)

Since any number divided by itself is equal to 1, we can simplify the expression one last time to get our final answer:

√(3) / (2 * 2 * 2) = 1/2 * 1/2 * 1/2 = 1/8

Therefore, the simplified form of the expression √3/√8 is 1/8.

Reciprocal of zero is undefined. So all the real numbers do not have the

The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.

We have the statement,

''All real numbers have a reciprocal''.

To find a counterexample:

The reciprocal of the number zero will always have the value "undefined".

Since there is no number that, when multiplied by zero, produces the result 1.

If n is a real number, then 1/n will be n's reciprocal.

n = 1,

So, the reciprocal of 1 is 1/1 = 1.

n = -7,

So, the reciprocal of -7 is 1/-7= -1/7.

And n = 1/4

So, the reciprocal of 1/4 is 1/(1/4)= 4/1 = 4.

By evaluating a linear equation, we get that the amount she spent is $ 8.20 at the coffee shop.

What is linear equation explain?

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept is called a "linear equation of two variables," where y and x are the variables.

Assuming x refills, the price is $ 2.95 for the initial cup and $ 1.50 for each additional cup.

     C(x) = $ 2.95 + $ 1.50 * x

We also know that she chose to purchase a bagel for $2.75 and that she received a $0.50 discount.

   By adding these we get

C(x) = $ 2.95 + $ 1.50 * x  + $ 2.75 = $ 0.50

C(x) = $5.20 + $ 1.50 * x

Now we want to find that she had 2 refills , then the total cost is

C(2) = $ 5.20 + $ 1.50 * 2

       = $ 8.20

Therefore, the total cost she spend at the coffee shop = $ 8.20
