How do I solve angle measurements and find the value of x on a polygon

Each term is 6 greater than the previous term.

First term is "7".

So,

a = 7

d = 6

Let's find the formula for the series,

We can immediately eliminate the firsst and third choice.

The variable is "t", so the general formula will be:

How many terms are there?

The series starts from t = 1,

since 6(1) + 1 = 6 + 1 = 7

and 6(2) + 1 = 12 + 1 = 13

The terms match!

So, 2nd answer choice is correct!!

Explanation

We need to present the information given in a table as follows:

The second column shows the probability of obtaining each event. Since they are equiprobable events, their probability are 1/6.

The next column determine the cost of obtaining each event; keeping in mid that each play costs $15.

The last column shows the expected value.

We know that If the value of the game is zero i.e. there is no loss or gain for any player, then the game is fair.

According to the table, there is a loss of 25/6, hence, the game is not fair.

We will have that the equation with no real solution is:

Because:

Based on the diagram, the base length of the new shape is half the circumference of the circle as indicated by 1/2C.

We know that the multiplication of both sides of the rectangle is the area of it.

In this case

We have here working with estimating a population proportion.

We have the following information from the question:

• The sample size, n, is equal to 1200 (n = 1200).

• We have that the fraction that responded "Yes" is 800.

• We need to find a 95% level of confidence for the margin error associated with the poll.

Now, we have the sample proportion for the sample size, n = 1200 is as follows:

Therefore, the sample proportion for the sample size is 800/1200, which is, approximately, 0.67.

The margin of error, in this case, is given by the next formula:

Where:

Now, we have that, for a level of confidence of 95%, the critical value is equal to z = 1.96:

Now, using all of the values at our disposal, we can use the formula to find the margin of error as follows:

Therefore, in summary, we have that:

1. The sample proportion is:

2. The margin of error associated with the poll is:

You have the following expression:

The area of the floor plan for the office is 2200 m².

We are given a diagram. The diagram shows the floor plan of an office. The height of the office is 50 meters. The length of the floor of the office is 55 meters. The width of the floor of the office is 40 meters. We need to find the area of the floor of the office.

The shape of the floor of the office is a rectangle. The area of a rectangle is calculated as the product of its length and width. Let the area of the floor of the office be represented by the variable "A".

A = 55*40

A = 2200

Hence, the area of the floor of the office is 2200 m².

Explanation:

assumption S1 is the distance to the grocery store

assumption S2 is the distance to the south post office

assumption S3 is the distance to the north bank

assumption S is the total distance

according to the question

S1= 10 miles S2=6 miles S3=8 miles

S=S1+S2+S3=10+6+8=24 miles

Required answer:

option D

she already had 44 photos

She took 24 photos each day for 6 days.

The function is:

y= 44+24x

where y is the total number of photos and x is the number of days.

The initial value is when x=0

y= 44+24(0) =44

The initial value is 44.

The formula for equation of line pasing through point (x_1,y_1) with slope m is,

Substitute point and slope in the equation to obtain the equation of line.

So equation of line is y=5x+4.

The expression would be:

Where x are the meters climbed.

For 2,000 m we'll have:

A 20°C decrease in temperature.

The equation of the line which represents the given graph is -3x + 6y = 36

We can infer from the graph that the equation of the line passes through the points (0,6) and (-12,0).

Therefore the slope of the line passing through these two points is given by:

m = (0-6)/(-12-0)

or, m = 1 / 2

Now we can use the general equation of the line to get the required equation.

y-6 = 1/2 (x-0)

or, 2y - x = 12

Now we will multiply throughout by 3 we get:

6y - 3x = 36

or, -3x + 6y = 36

The general equation for a straight line is y = mx + c, where m stands for the line's slope and c for its y-intercept. The most frequently used straight line equation is one that has to do with geometry.

There are numerous ways to express the equation of a straight line, such as slope-intercept form,  point-slope form, standard form, general form,  etc.

Hence the required equation is -3x + 6y = 36 .

The farmer would like to eclose a rectangle

First we know that the perimeter of the rectangle is

We also know that we have 36 ft of fence, that is we only can enclose a rectangle of 36 ft of perimeter. Then

From this we can find y

The area of the rectangle is

But we know the value of y, plugging this value into the last equation we have that

To find three possible values for the area we only have to give values to x. This values have to be positive (since we can't have a negative lenght). We also notice that the value can't exceed 18 since that would mean a zero area. With those point in consideration we choose three values between zero and 18.

If x=3, then the area is

If x=9, then the area is

if x=15, then the area is

Then we have three possible areas for the rectangle.

The maximum value for the area is 81, and we see that because the equation for the area is a parabola that opens down with vertex in the point (9,81)

The sum of integers should be written like:

First, let's find the area circular sector:

Where:

Now, let's find the area of the triangle, that triangle is an isosceles triangle, so, we can use the following formula in order to find its area:

where:

s = one of the equal sides = 7

θ = angle = 150

so:

Therefore, the area of the white region will be, the area of the circular sector minus the area of the isosceles triangle, so:

-34 = x*y

Considering the provided measures, we are going to calculate the requested surface area, so we obtain the following:

So to calculate the surface area we will use the following formula:

A = a(a + √(a^2 + 4h^2))

A = 8 cm(8cm + √((8 cm)^2 + 4(3 cm)^2))

A = 8 cm(8cm + √(64 cm^2 + 4*9 cm^2))

A = 8 cm(8cm + √(64 cm^2 + 36 cm^2))

A = 8 cm(8cm + √(100 cm^2))

A = 8 cm(8cm + 10 cm)

A = 8 cm(18 cm)

total surface areaA = 144 m^2

Finally we obtain that the total surface area is equal to 144 m^2
