Answer:

75.25

Step-by-step explanation:

to find the area of the square you multiply 5.5×5.5

you then add that to the are of the trapezoid using the formula a=a+b/2 h

you plug it all in and get (5.5×5.5)+((5.5+9.5/2)6)

Step-by-step explanation:here is a example:Recall that the volume of a regular prism is given by the area of the base times the height.

Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.

The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.

Recall that the are of a triangle is given by 1/2 base times height.

Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by volume=7x(2x+1)=14x2+7x

The scale factor showing the view of the original building as a dilation of the toy is 0.00111.

The scale factor is a smaller or bigger representation of an object or shape.

The scale factor shows the ratio of the bigger or smaller scale to the original scale.

The scale factor shows the dilation of the toy when the new scale is reduced.  It can also show the larger transformation of the toy when the original scale is increased by the scale factor.

The area of the scale model of the front side of the toy building = 1 ft²

The area of the front side of the original building = 900 ft²

The scale factor = 0.00111 (1 ft²/900 ft²)

Thus, we can conclude that the toy train's scale model is dilated by a scale factor of 0.00111.

A go-fuel kart's and maintenance costs are calculated as follows: c=10x+1200, where x is the number of rides. $40 is the cost per ride. it takes x = 40 to break even.

The cost function given here is

c(x) = 10x + 1200

Where x = number of rides

c(x) is the total cost including the fixed cost.

Also it is given that each ride costs $40

So Revenue function for x number of rides shall be

R(X) = 40x

For break even

the cost must be equal to the revenue

Hence

R(x) = C(x)

40x = 10x + 1200

Subtracting 10x from both sides we get

30x = 1200

Dividing by 30 on both sides

Orthocenter: Solve system of 3 eqs. using 3 altitudes' equation & vertices' coordinates.

What is coordinate ?

Coordinate is a value or set of values that identify the position of a point in a certain space. Represented by ordered pair or triple of numbers (x,y) or (x,y,z) respectively.

The orthocenter of a triangle is the point where the three altitudes of the triangle intersect. To find the orthocenter of a triangle with coordinates, you can use the following steps:

1) Find the equation of the three altitudes of the triangle. To do this, you will need the coordinates of the three vertices of the triangle, as well as the slope of the line perpendicular to the side opposite each vertex.

2) Once you have the equations of the three altitudes, you can use them to find the coordinates of the orthocenter. To do this, you will need to solve a system of three equations with three variables (the x and y coordinates of the orthocenter, and the y-intercept of the altitude).

3) Once you have the coordinates of the orthocenter, you can use them to check your work by verifying that the point is indeed on each of the three altitudes.

The ratio of the central angle measure to the circumference of a circle is called the "arc measure" and it is given by the formula:

arc measure = central angle measure / circumference

For a given central angle measure in degrees, the formula will be:

arc measure = (central angle measure in degrees) / 360

It's worth noting that this ratio is equal to the fraction of the circumference that the arc of the central angle measures.

For example, if the central angle measure is 90 degrees, the arc measure will be 90/360 = 1/4, meaning that the arc that is formed by the central angle measure is 1/4 of the circle's circumference.

It's also important to note that this ratio is also equal to the fraction of the total area of the circle that the sector formed by the central angle measures.

It's also worth noting that this ratio is always less than 1, since the central angle can't be greater than 360 degrees.

Therefore, The ratio of the central angle measure to the circumference of a circle is called the "arc measure" and it is given by the formula: arc measure = central angle measure / circumference

Nico, Raj and Sandra are correct.

And the explanation is given.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

An equation,

2/5(5 +x) = 8.

Nico, Aditi, Erick, Raj, and Sandra are solving the equation.

Approach 1:

Multiply by 5/2.

(5/2)(2/5)(5 +x) = 8(5/2)

5 + x = 20

x = 15.

Approach 2:

Multiply by 1/2 both sides

(1/2)(2/5)(5 +x) = 8(1/2)

5 + x = 4(5)

x = 15.

Approach 3:

Simplifying,

2 + 2/5x = 8

2x/5 = 6

x = 30/2

The graphs of absolute value functions are called "V-shaped" or "V-graphs" because their graph is in the shape of a "V".

The graph of an absolute value function is a V-shape that opens upward or downward, depending on the function.

The vertex of the V is the point where the absolute value function equals zero. The two arms of the V extend out from this point, going in opposite directions along the number line.

The absolute value function is defined as |x| where x is any real number and |x| represents the distance of x from zero on the number line, i.e., always non-negative.

Example of an absolute function is f(x) = |x + 3|. The vertex is where

x + 3 = 0

That is at x = -3.

Here the function opens upward, but if the function was -|x + 3|, it will open downward.

The surface area that minimizes the weight of the storage bin is:

70x cm^2

To minimize the weight of an open-top storage bin in the shape of a rectangular prism, we need to minimize its surface area.

The volume of the storage bin is given as 3500 cm^3. Since the base of the bin is a square, we can let the length of one side of the base be x cm.

Therefore, the area of the base is x^2 cm^2.

          V = x^2 * h

where V is the volume and h is the height of the bin

So, we can substitute the value of V in the above equation to get:

3500 = x^2 * h

To minimize the surface area of the bin, we must minimize the sum of the areas of all its faces. The surface area of the rectangular prism is given by the formula:

           2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism respectively.

Since the base of the bin is a square, we can let the length and width be equal to x. Therefore, we can use the equation of the height of the bin and the formula of the surface area of the rectangular prism to get:

     2x^2 + 2xh = 2x^2 + 2x(3500/x^2)

Now, we can simplify the above equation to:

       2x^2 + 2x(3500/x^2) = 2x^2 + 70x

To minimize the surface area, we need to minimize the value of x. We can see that the second term of the equation is a linear function of x and has a negative slope, which means that as x increases, the surface area decreases. Therefore, the surface area will be minimized when x is at its maximum value.

   Therefore, the surface area that minimizes the weight of the storage bin is 70x cm^2.

Answer:

y = 5/2 x - 13

Step-by-step explanation:

A line perpendicular to y=-2/5x-1 has a slope equal to the negative reciprocal of -2/5. The slope of the line passing through (2,-8) can be calculated as follows:

m = -(-5/2) = 5/2

The equation of the line in point-slope form is:

y - (-8) = (5/2)(x - 2)

Expanding the equation gives:

y + 8 = 5/2 x - 5

Solving for y:

y = 5/2 x - 5 - 8

y = 5/2 x - 13
