c. Mr. Wilkins is laying bricks to make a
rectangular patio. The
area he is covering with bricks is 15 1/2 feet by 9 3/4 feet. What
is the area of the patio?

Answer:

<P = 78.625°

Step-by-step explanation:

All of the angles in a triangle add up to 180.

<R + <Q + <P = 180

We can use x for <P and <Q, as they represent the same value because they are congruent.

<R + x + x = 180

Now, we want to substitute known values in and work backwards to find out what angle <P and <Q are.

2x + <R = 180

Put 22.75 in for <R.

2x + 22.75 = 180

Subtract on both sides.

2x = 157.25

Divide 2 on both sides to isolate x

x = 78.625

Since x represents <P and <Q, that means they are both 78.625 degrees each.

<P = 78.625

The average monthly payment made by the customer is $638.

In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.

Given that,

The cost of Sedan for three years is $22,968.

The time in months can be calculated as,

3 × 12 = 36 months

The average payment per month can be found by dividing the total amount by total number of months as follows,

Average monthly payment = 22968/36

                                            = 638

Hence, the average monthly payment made by a customer in the  interest-free period is $638.

Length is 33.33 feet and width is 25 feet are dimensions should

be used so that the enclosed area will be a maximum.

The area of Rectangle is length times of width

Given that, a rancher has 200 feet of fencing to enclose two adjacent rectangular corrals of the same dimensions.

Here, the dimensions of the rectangles are the same.

The width of the two rectangles is W=2W+2W=4W

The length of the two rectangles is L=L+L+L=3L

Because the adjacent side has a common length.

3L+4W=200

3L=200-4W

Divide both sides by 3

L=(200-4W)/3

Let us form an equation using the area of rectangle formula:

A=2LW

=2(200-4W)/3.W

A=400-8W²/3

Let us differentiate to get the area to be maximized dA/dW=0

1/3×(400-8W²)=0

1/3(400-16W)=0

400-16W=0

400=16W

Divide both sides by 16

W=25

The width is 25 feet.

Substitute W value in equation to get L value:

L=200-4×25/3

=200-100/3

=100/3

=33.33

The length is 33.33 feet.

Now let us find the maximum area

A=2LW

=2×33.33×25

=1666.66

Hence, length is 33.33 feet and width is 25 feet are dimensions should

be used so that the enclosed area will be a maximum.

Using the coordinates of the vertices of a polygon (-3, 1), (-3, 3), (-1, 5), (2, 4), and (2, 1) the perimeter of the polygon is 16.0 units

The perimeter is calculated by summing the sides

The length of line in an ordered pair is calculated using the formula

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

where

d = distance between the points

x₂ and x₁ = points in x coordinates

y₂ and y₁ = points in y coordinates

(-3, 1) and (-3, 3) =√{(-3 - -3)² + (3 - 1)²} = 2

(-3, 3) and (-1, 5) = √{(-1 - -3)² + (5 - 3)²} = 2√2

(-1, 5) and (2, 4) = √{(2 - -1)² + (4 - 5)²} = √10

(2, 4) and (2, 1) = √{(2 - 2)² + (1 - 4)²} = 3

(2, 1) and (-3, 1) = √{(-3 - 2)² + (1 - 1)²} = 5

The equation of the new parabola, that is, the image of the parabola f(x) = x² is g(x) = - (1 / 8) · x².

In this problem we must determine the image of the parabola f(x) = x², which is the result of a sequence of two rigid transformations: (i) Reflection across the x-axis, (ii) Dilation. Each kind of rigid transformation is described below:

Reflection across the x-axis

f'(x) = - f(x)

Dilation

g(x) = k · f'(x), where k is the scale factor.

Now we proceed to determine the equation of the new parabola:

The perimeter of the figure described in the question is 42.84cm

The figure is defined by a half circle is joined to an equilateral triangle with side lengths of 12 units.

So the perimeter of the figure will be equal to half of the circumference of the triangle plus the length of the two exposed sides of the triangle.

The diameter of the circle will also be 12 units, remember that the circumference of a circle of diameter D is:

C = 3.14*D

In this case, the circumference of half circle is:

C = 3.14*D/2

Replacing the value of the diameter:

C = 3.14*12cm/2 = 18.84cm

Adding the two sides of the triangle we get the perimeter.

P = 18.84cm + 2*12cm = 42.84cm

What is an isosceles triangle?

A triangle with two sides that have the same length is said to be an isosceles. When two sides of an isosceles triangle are equal, the angles across from those two sides likewise match up and are always equal.

Given that, the isosceles triangle then

two angles are equal

So, (5x-7)° = (8x-55)°

The cost of sheet metal per square​ foot is $20.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The general equation of a straight line is -

y = mx + c

[m] is called slope and it tells the unit rate of change in [y] with respect to [x].

We have a contractor bought 10.8 ft² of sheet metal. He has used 2.3 ft² so far and has ​$170 worth of sheet metal remaining.

The equation 10.8x − 2.3x = 170 represents how much sheet metal is remaining and the cost of the remaining amount.

We have the following equation -

10.8x − 2.3x = 170

8.5x = 170

x = 170/8.5

x = 20

Therefore, the cost of sheet metal per square​ foot is $20.
