Step-by-step explanation:

remember, the sum of all angles in a triangle is always 180°.

and the sum of all angles around a single point on one side of a line is also always 180° (because that line is like a diameter of any circle with that point as center, and half a circle is 180°).

3)

the third inner angle of the triangle is

180 = 63 + 51 + angle = 114 + angle

angle = 66°.

x = 180 - 66 = 114°

4)

the third inner angle of the triangle is

180 = 86 + 45 + angle = 131 + angle

angle = 49°

x + 30 = 180 - 49 = 131°

x = 101

Some have proposed that the playing a card game previously worked as "play cash" and addressed the stakes utilized for other betting games, and later turned out to be essential for the actual games. Others have proposed associations between playing a card game and chess or dice games, yet this is again theoretical.

Surveys, Experiments, and Observational studies are some common methods of data collection in statistical studies that involve people.

A survey is a means to gather information about a group of individuals by asking some of them to respond to questions. A survey may require participants to fill out forms, respond to online questionnaires, take part in in-person interviews, or respond to questions over the phone.

In an experiment, as opposed to an observational study, different treatments are purposefully applied to several groups, and the groups are then compared to see whether there are any differences in a certain variable of interest termed a response. Researchers can determine whether various treatments have distinct effects by using a well-designed experiment.

In an observational study, a researcher utilizes data from observations to learn about a group of people. Aside from assessing their replies, the people being watched are particularly not hampered.

The attached below is the graph and the three points to solve the equation is (0,1) , (1,5/2) and (-1,-1/2)

According to the question the equation that we have been given is

              -3x + 2y = 2

We need to graph the linear equation. For this we will first put different values of x in the above equation and then find the values of y which will be the coordinates of the graph.

First put x = 0

                  -3(0) + 2y = 2

                         2y = 2

                          y = 1

hence the first coordinate is (0,1)

Similarly put,     x = 1

                       -3(1) + 2y = 2

                           2y = 5

                             y = 5/2

            when x= -1 then y = -1/2

Thus the three point or coordinates are (0,1) , (1,5/2) and (-1,-1/2) and below is the graph.

Using proportions, the solution for the golden section is given as follows:

|AC|/|AB| = 1.6181.

A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.

For this problem, the segment lengths are given as follows:

The following proportion is true for the segment:

|AC|/|AB| = |AB|/|BC|

Hence:

1/x = x/1 - x.

x² = 1 - x

x² + x - 1 = 0.

Which is a quadratic equation with solution x = 0.618.

Then the solution for the golden section is given as follows:

|AC|/|AB| = 1/x = 1/0.618 = 1.6181.

Answer:

  (1 +√5)/2 ≈ 1.618034

Step-by-step explanation:

Given point B on segment AC, you want the "golden proportion" ratio AC/AB, such that AC/AB = AB/BC. A diagram is shown with A=0, B=x, C=1.

We can solve for the golden proportion directly by redefining points on the line segment as ...

Then we have AB = 1, AC = r, BC = r-1 and the proportion of interest is ...

  AC/AB = AB/BC

  r/1 = 1/(r -1)

Cross-multiplying gives ...

  r² -r = 1

Completing the square, we have ...

  r² -r + 1/4 = 5/4

  (r -1/2)² = 5/4

Taking the square root gives ...

  r - 1/2 = 1/2√5

  r = 1/2 + 1/2√5 = (1 +√5)/2 ≈ 1.618034

The golden ratio is (1+√5)/2 ≈ 1.618034.

The magnitude of the resultant velocity of the soccer ball is 10 m/s .

Let the horizontal component of velocity be [tex]V_{x}[/tex] and the vertical component  of velocity be [tex]V_{y}[/tex].

The magnitude of the resultant velocity will be represented by V.

So, we can write

The horizontal component of velocity = [tex]V_{x}[/tex] = 8 m/s

The vertical component  of velocity = [tex]V_{y}[/tex] = 6 m/s

The relation between horizontal component, vertical component and resultant velocity is,

[tex]V^{2} = V_{x} ^{2} + V_{y} ^{2}[/tex]

On substituting value of horizontal component and vertical component, we get

[tex]V^{2}[/tex] = [tex](8)^{2} + (6)^{2}[/tex]

[tex]V^{2}[/tex] = 64 + 36

[tex]V^{2}[/tex] = 100

The function which can be used to determine the amount of money he has left over after x rides is f(x)=-2x+70.

This function is linear. A linear variable function can be written in the form of y=f(x)=a+bx, where a and b are integers and x, is the variable. This function has one independent variable and one dependent variable. In the above given function y=f(x)=a+bx; y is the dependent variable and x is the independent variable.

Here since x number of rides are taken and the cost per ride is x so the total cost of x rides is given as 2x.

Since there is a total of $100 and an amount of ($10+$20=$30) is spent on entry and food respectively.

Therefore, total amount left after all the expenses can be expressed as:

f(x)=100-(30+2x)

f(x)=70-2x

f(x)=-2x+70

It takes Hiroshi 30 years to reach his investment goal.

The formula for calculating the amount received on the principal amount (P) after t years at r% rate of interest is-

Amount = P(1 + r/100)^t

Let the principle amount with Hiroshi be P

then, the amount that Giulio starts with = 3P

Let time period for Giulio's investment = t

Then, the time period for Hiroshi's investment = 5t

Rate = 5%

As the investment goals of both the people are equal, they will get the same amount.

Therefore, we get the following equation-

P(1 + 20/100)^5t/4 = 3P(1 + 20/100)^t/4

(1 + 20/100)^5t/4 = 3(1 + 20/100)^t/4

[(1 + 20/100)^5t/4] /[(1 + 20/100)^t/4] = 3

(1 + 20/100)^(5t/4- t/4) = 3

(1 + 20/100)^(4t/4) = 3

(1 +0.2)^t = 3

(1.2)^t = 3

Taking log on both sides-

Log (1.2)^t = log 3

t log 1.2 = log 3

t = log 3/ log 1.2

t = 6.025

Time taken by Hiroshi to reach his investment goal = 5t

= 5(6.025)

= 30.128

Thus, it takes Hiroshi 30 years to reach his investment goal.

Convert 99 grams into pounds is 0.22.

In the US, the pound is the unit of mass that is utilized. It is symbolized by the letter lbs. Therefore, we must calculate the estimated number of grams in a pound. Both pounds and grams can be converted into one another as units of mass.

Since both systems of units may carry the same mass, the fundamental conversion rate between pounds and grams is crucial for international trade. Because just writing the numbers makes no sense, units should always be written after the final solution has been evaluated. The method of transposition may be used to discover the conversion of a given number of values from one unit to another by multiplying or dividing both sides of the equation by the same number.
