evaluate 150-(2=x)3 when x=2

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

The function is determined using speed and is found to be d = 120t.

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.

120 = d/t

Hence, d = 120t.

Answer:

Step-by-step explanation:

A parallelogram has 4 sides.

Each pair of opposite sides is congruent.

To find the perimeter, find the length of 2 adjacent sides and multiply by 2.

Length of side (0, 0) to (5, 0) is 5.

Length of side (5, 0) to (8, 4) is the hypotenuse of a right triangle with legs of lengths 3 and 4.

a² + b² = c²

3² + 4² = c²

c² = 9 + 16

c² = 25

c = √25

c = 5

The hypotenuse measures 5 units.

perimeter = 2(5 + 5)

perimeter = 2(10)

perimeter = 20

Answer:

To factor the expression 2/3x + 4, we first need to find the greatest common factor (GCF) of the coefficients of the terms in the expression. In this case, the GCF is 2/3, so we can write the expression as (2/3)(x + 12/2). This is the factored form of the expression, and it can be simplified to (1/3)(2x + 6).

7.79 percent.

Take 7.79 percent of 74,000.

0.0779 * 74,000 = 5764.6

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

The fuel efficiency for the speed of 60 mph is (d) 38.55 mpg

From the question, we have the following least-squares regression line equation that can be used in our computation:

ln(Fuel Efficiency) = 1.437 +0.541 In(Speed)

Also from the question, we have the following parameters:

Speed = 60 mph

This means that we substitute 60 mph for speed in the given equation

ln(Fuel Efficiency) = 1.437 + 0.541 In(Speed)

So, we have the following representation

ln(Fuel Efficiency) = 1.437 + 0.541 In(60)

Take the natural logarithm of 60

This gives

ln(Fuel Efficiency) = 1.437 + 0.541 * 4.09434456222

Evaluate the products

So, we have the following representation

ln(Fuel Efficiency) = 1.437 + 2.21504040816

Evaluate the sum

So, we have the following representation

ln(Fuel Efficiency) = 3.65204040816

Take the exponent of both sides

Fuel Efficiency = e^(3.65204040816)

Evaluate

Fuel Efficiency = 38.5532502162

Fuel Efficiency = 38.55 mpg

Step-by-step explanation:

The points on the rhombus M(?, 0) and H(5, 0), and the location of the point O of the rhombus, indicates that the length of a side of a rhombus is 5 units from which Pythagorean Theorem indicates that the x-coordinate of the point M is 3

Pythagorean Theorem states that the sum of the squares of the legs of a right triangle is equivalent to the square of the length of the hypotenuse side of a right triangle.

The shape of the quadrilateral RHOM = A rhombus

The specified coordinates of the vertices of the rhombus are;

Point M = (?, 4)

Point H = (5, 0)

A rhombus is a parallelogram that have all four sides of the same length

The length of side OH, which is on the x-axis  = 5 - 0 = 5

Therefore, the length of OM = 5 (properties of a rhombus)

Let x represent the x-coordinate of the point M

According to Pythagorean Theorem, we get;

x² + 4² = 5²

Where x = The horizontal distance of the point M from the y-axis

x² = 5² - 4² = 9

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

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

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
